Domain Name System (DNS)

What is Domain Name System (DNS)? How DNS Works?

Domain Name System (DNS)

Domain Name System (  DNS ) is a hierarchical naming system distributed over open  (WAN) or closed networks  (LAN) and built on a database.

The most  important feature is that it converts human-readable and catchy domain names  (eg: R10.net) to the IP  (Internet Protocol) address of the connected network device,  allowing the world to find and connect the relevant device.

DNS is a system responsible for the translation of a domain name to its IP address in the global database.

In the early days of the Internet, it was easy for people to remember their respective IP addresses because of restricted IP addresses. However, after a while, it became difficult to remember these IP addresses. As the number of servers and  clients in the network  increased, it became increasingly difficult to operate with IP addresses in mind. Even if it is possible to reach a site that you already know its IP address directly with its IP address,  DNS is of great importance today.

The emergence of DNS

In order to link these domain names and IP addresses together in the early days of the Internet,  Elizabeth Feinler of Stanford defined a file named “hosts.txt” with IP and domain name matches for each computer connected to the Internet  . When this situation started to become insufficient with the growth of the internet day by day, in 1983,  USC  (University of Southern California) research assistant named Paul Mockapetris was assigned to solve this problem. The solution was a solution called DNS that we use today  .

Today, DNS standards  are set by the Internet Engineering Task Force  (IETF) .

How do DNS servers work?

DNS directories are distributed worldwide and  are stored on specialized servers called DNS servers  (DNS servers) that communicate with each other.

DNS servers store and present information to clients that map a domain name to one or more IP addresses.

When the client tries to go to a domain address, the DNS server, which is at the optimum distance to the person, directs the relevant request to the IP address and the client accesses the device related to the domain name. With DNS caching, this process can be optimized and performance can be increased.

Accelerating transformation with SAP on Azure

Microsoft continues to expand its presence in the cloud by building more data centers globally, with over 61 Azure regions in 140 countries. They are expanding their reach and capabilities to meet all the customer needs. The transition from a cloudless domain like DRDC to the entire cloud platform is possible within no time, and a serverless future awaits. Microsoft gives the platform to build and innovate at a rapid speed. Microsoft is enhancing new capabilities to meet cloud services' demands and needs, from IaaS to PaaS Data, AI, ML, and IoT. There are over 600 services available on Azure with a cloud adoption framework and enterprise-scale landing zone. Many companies look at Microsoft Azure security compliance as a significant migration driver. Microsoft Azure has an extensive list of compliance certifications across the globe. The Microsoft services have several beneficial characteristics; capabilities are broad, deep, and suited to any industry, along with a global network of skilled professionals and partners. Expertise in the Microsoft portfolio includes both technology integration and digital transformation. Accountability for the long term, addressing complex challenges while mitigating risk. Flexibility to engage in the way that works for you with the global reach to satisfy the target business audience.

SAP and Microsoft Azure

SAP and Microsoft bring together the power of industry-specific best practices, reference architectures, and professional services and support to simplify and safeguard your migration to SAP in the cloud and help manage the ongoing business operations now and in the future. SAP and Microsoft have collaborated to design and deliver a seamless, optimized experience to help manage migration and business operations as you move from on-premises editions of SAP solutions to SAP S/4 HANA on Microsoft Azure. It reduces complexity, minimizes costs, and supports end-to-end SAP migration and operations strategy, platform, and services. As a result, one can safeguard the cloud migration with out-of-box functionality and industry-specific best practices while immaculately handling the risk and optimizing the IT environment. Furthermore, the migration assimilates best-in-class technologies from SAP and Microsoft, packed with a unified business cloud platform. 

SAP Deployment Options on Azure

SAP system is deployed on-premises or in Azure. One can deploy different systems into different landscapes either on Azure or on-premises. SAP HANA on Azure large instances intend to host the SAP application layer of SAP systems in Virtual Machines and the related SAP HANA instance on the unit in the 'SAP HANA Azure Large Instance Stamp.' 'A Large Instance Stamp' is a hardware infrastructure stack that is SAP HANA TDI certified and dedicated to running SAP HANA instances within Azure. 'SAP HANA Large Instances' is the official name for the solution in Azure to run HANA instances on SAP HANA TDI certified hardware that gets deployed in ‘Large Instance Stamps’ in different Azure regions. SAP or HANA Large Instances or HLI are physical servers meaning bare metal servers. HLI does not reside in the same data center as Azure services but is in close proximity and connected through high throughput links to satisfy SAP HANA network latency requirements. HLI comes in two flavors- Type 1 and 2. IaaS can install SAP HANA on a virtual machine running on Azure. Running SAP HANA on IaaS supports more Linux versions than HLI. For example, you can install SAP Netweaver on Windows and Linux IaaS Virtual Machines on Azure. SAP HANA can only run on RedHat and SUSE, while NetWeaver can run on windows SQL and Linux.

Azure Virtual Network

Azure Virtual Network or VNET is a core foundation of the infrastructure implementation on Azure. The VNET can be a communication boundary for those resources that need to communicate. You can have multiple VNETs in your subscription. If they weren't connected, we could call them Pierre in Azure wall; there will be no traffic flow in between. They can also share the same IP range. Understanding the requirements and proper setup is essential as changing them later, especially with the running production workloads, could cause downtime. When you provision a VNET, The private blocks must allocate address space. If you plan to connect multiple VNETs, you cannot have an overlapping address space. The IP range should not clash or overlap with the IP addressing in Azure while connecting on-premise to Azure via express route or site-site VPN. Configuring VNET to the IP address space becomes a DHP service. You can configure VNET with the DNS server's IP addresses to resolve services on-premise.VNETS can be split into different subnets and communicate freely with each other. Network security groups or NSGs are the control planes we use to filter traffic. NSGs are stateful but simple firewall rules based on the source and destination IP and ports.

 Azure Virtual Gateway

 For extensive connectivity, you must create a virtual gateway subnet. When you create a virtual gateway, you will get prompted for two options: VPN or Express Route Gateway; with VPN, you cannot connect to the Express Route Circuit. If you choose the Express Route Virtual Gateway, you can combine both.

 There are two types of VPN;

1) The point-to-site VPN is used for testing and gives the lowest throughput.

2) The site-site VPN connection can offer better benefits by bridging networks.

This VPN offers zero support for SLA and uses this connection as a backup for the recommended connection on Azure, called the express route. Express route is a dedicated circuit using hardware installed on your data center, with a constant link to ‘Microsoft Azure Edge’ devices. Express route is inevitable for maintaining the communication between application VNET running in Azure and on-premise systems to HLI servers. The express route is safer and more resilient than VPN as it provides a connection through a single circuit and facilitates second redundancy; this helps route traffic between SAP application servers inside Azure and enables low latency. Furthermore, the fast path allows routine traffic between SAP application servers inside Azure VNET and HLI through an optimized route that bypasses the virtual network gateway and directly hops through edge routers to HLA servers. Therefore, an ultra-performance express route gateway must have a Fast Path feature.

SAP HANA Architecture (VM)

This design gets centered on the SAP HANA backend on the Linux Suse or RedHat distributions. Even though the Linux OS implementation is the same, the vendor licensing differs. It incorporates always-on replication and utilizes synchronous and asynchronous replication to meet the HANA DB requirements. We have also introduced NetApp file share for DFS volumes used by each SAP component using Azure site recovery and building a DR plan for App ASCs and the web dispatches servers. Azure Active directory is used in synchronization with on-premises active directory, as SAP application user authenticates from on-premises to SAP landscape on Azure with Single Sign-On credentials. Azure high-speed express route gateway securely connects on-premises networks to Azure virtual machines and other resources. The request flows into highly available SAP central, SAP ABAP services ASCS and through SAP application servers running on Azure virtual machines. The on-demand request moves from the SAP App server to the SAP HANA server running on a high-performance Azure VM. Primary active and secondary standby servers run on SAP-certified virtual machines with a cluster availability of 99.95 at the OS level. Data replication is handled through HSR in synchronous mode from primary to secondary enabling zero recovery point objective. SAP HANA data is replicated through a disaster recovery VM in another Azure region through the Azure high-speed backbone network and using HSR in asynchronous mode. The disaster recovery VM can be smaller than the production VM to save costs.

SAP systems are network sensitive, so the network system must factor the design decisions into segmenting the VNETs and NSGs. To ensure network reliability, we must use low latency cross-connections with sufficient bandwidth and no packet loss. SAP is very sensitive to these metrics, and you could experience significant issues if traffic suffers latency or packet loss between the application and the SAP system. We can use proximity placement groups called PGS to force the grouping of different VM types into a single Azure data center to optimize the network latency between the different VM types to the best possible.

 Security Considerations

 Security is another core pillar of any design. Role-based Access control (RBAC) gets accessed through the Azure management bay. RBAC is backed up through AD using cloud-only synchronized identities. Azure AD can back up the RBAC through cloud-only or synchronized identities. RBAC will tie in those cloud or sync identities to Azure tenants, where you can give personal access to Azure for operational purposes. Network security groups are vital for securing the network traffic both within and outside the network environment. The NSGs are stateful firewalls that preserve session information. You can have a single NSG per subnet, and multiple subnets can share the same energy. Application security group or ASG handles functions such as web servers, application servers, or backend database servers combined to perform a meaningful service. Resource encryption brings the best of security with encryption in transit. SAP recommends using encryption at rest, so for the Azure storage account, we can use storage service encryption, which would use either Microsoft or customer-managed keys to manage encryption. Azure storage also adds encryption in transit, with SSL using HTTPS traffic. You can use Azure Disk Encryption (ADE) for OS and DBA encryption for SQL.

Migration of SAP Workloads to Azure

The most critical part of the migration is understanding what you are planning to migrate and accounting for dependencies, limitations, or even blockers that might stop your migration. Following an appropriate inventory process will ensure that your migration completes successfully. You can use in-hand tools to understand the current SAP landscape in the migration scope. For example, looking at your service now or CMDB catalog might reveal some of the data that expresses your SAP system. Then take that information to start drawing out your sizing in Azure. It is essential to ensure that we have a record of the current environment configuration, such as the number of servers and their names, server roles, and data about CPU and memory. It is essential to pick up the disk sizes, configuration, and throughput to ensure that your design delivers a better experience in Azure. It is also necessary to understand database replication and throughput requirements around replicas. When performing a migration, the sizing for large HANA instances is no different from sizing for HANA in general. For existing and deployment systems you want to move from other RDBMS to HANA, SAP provides several reports that run on your existing SAP systems. If migrating the database to HANA, these reports need to check the data and calculate memory requirements for the HANA instances.

When evaluating high availability and disaster recovery requirements, it is essential to consider the implications of choosing between two-tier and three-tier architectures. To avoid network contention in a two-tier arrangement, install database and Netweaver components on the same Azure VM. The database and application components get installed in three-tier configurations on separate Azure Virtual Machines. This choice has other implications regarding sizing since two-tier, and three-tier SAP ratings for a given VM differs. The high availability option is not mandatory for the SAP application servers.

You can achieve high availability by employing redundancy. To implement it, you can install individual application servers on separate Azure VMs. For example, you can achieve high availability for ASCS and SCS servers running on windows using windows failover clustering with SIOS data keeper. We can also achieve high availability with Linux clustering using Azure NetApp files. For DBMS servers, you should use DB replication technology using redundant nodes. Azure offers high availability through redundancy of its infrastructure and capabilities, such as Azure VM restarts, which play an essential role in a single VM deployment. In addition, Azure offers different SLAs depending on your configuration. For example, SAP landscapes organize SABC servers into different tiers; there are three diverse landscapes: deployment, quality assurance, and production.

Migration Strategies:- SAP landscapes to Azure

 Enterprises have SAP systems for business functions like Enterprise Resource Planning(ERP), global trade, business intelligence(BI), and others. Within those systems, there are different environments like sandbox developments, tests, and production. Each horizontal row is an environment, and each vertical dimension is the SAP system for a business function. The layers at the bottom are lower-risk environments and are less critical. Those towards the top are in high-risk environments and are more critical. As you move up the stack, there is more risk in the migration process. Production is the more critical environment. The use of test environments for business continuity is of concern. The systems at the bottom are smaller and have fewer computing resources, lower availability, size requirements, and less throughput. They have the same amount of storage as the production database with a horizontal migration strategy. To gain experience with production systems on Azure, you can use a vertical approach with low-risk factors in parallel to the horizontal design.

 Horizontal Migration Strategy

 To limit risk, start with low-impact sandboxes or training systems. Then, if something goes wrong, there is little danger associated with users or mission-critical business functions. After gaining experience in hosting, running, and administering SAP systems in Azure, apply to the next layer of systems up the stack. Then, estimate costs, limiting expenditures, performance, and optimization potential for each layer and adjust if needed.

Vertical Migration Strategy

The cost must be on guard along with legal requirements. Move systems from the sandbox to production with the lowest risk. First, the governance, risk, compliance system, and the object Event Repository gets driven towards production. Then the higher risk elements like BI and DRP. When you have a new system, it's better to start in Azure default mode rather than putting it on-premises and moving it later. The last system you move is the highest risk, mission-critical system, usually the ERP production system. Having the most performance virtual machines, SQL, and extensive storage would be best. Consider the earliest migration of standalone systems. If you have different SAP systems, always look for upstream and downstream dependencies from one SAP system to another.

Journey to SAP on Azure

Consider two main factors for the migration of SAP HANA to the cloud. The first is the end-of-life first-generation HANA appliance, causing customers to reevaluate their platform. The second is the desire to take advantage of the early value proposition of SAP business warehouse BW on HANA in a flexible DDA model over traditional databases and later BW for HANA. As a result, numerous initial migrations of SAP HANA to Microsoft Azure have focused on SAP BW to take advantage of SAP HANA's in-memory capability for the BW workloads. In addition, using the SAP database migration option DMO with the System Migration option of SUM facilitates single-step migration from the source system on-premises to the target system residing in Azure. As a result, it minimizes the overall downtime. In general, when initiating a project to deploy SAP workloads to Azure, you should divide it into the following phases. Project preparation and planning, pilot, non-production, production preparation, go-live, and post-production.

Gnoppix free DoH Server

What is DoH and why it’s important

 DNS: The Address Book with a Privacy GapThe Domain Name System (DNS) acts like an address book for the internet, translating user-friendly domain names (like Gnoppix) into numerical IP addresses that computers use. Designed in 1987, DNS didn't prioritize security or privacy. By default, DNS requests travel unencrypted, making them vulnerable to eavesdropping and manipulation. This means anyone can potentially see which websites you're trying to access.A famous example of this vulnerability is the case of Kevin Mitnick. He was caught by the FBI because he used unencrypted traffic. The FBI was not able to decrypt traffic, they were able to track his activity by monitoring unencrypted DNS requests within a group of people requesting DNS at that specific time, after interviewing them all, it was obvious who has the skills to do that. While it's true that current encryption methods for data traffic are very strong and cannot be decrypted with today's technology, the future of quantum computing might change this. Quantum computers have the potential to break many current encryption methods, which could have a significant impact, especially for financial institutions. However, the development of large-scale quantum computers is likely to be delayed for some time. The Great Firewall's DNS TrickeryChina's Great Firewall of China (GFW) exploits this weakness to censor content. Since DNS relies on a simple, unencrypted protocol, the GFW can impersonate both the user and the server to alter DNS responses. When a user tries to access a blocked website (like thepiratebay), the GFW can provide a fake IP address, directing the user to a different location within China instead of the real website. Securing Your DNS with DoHJust like HTTPS encrypts website traffic, DNS over HTTPS (DoH) encrypts your DNS requests. With DoH, your internet service provider (ISP) or other observers cannot see which websites you're trying to access. This adds a layer of privacy and security to our online browsing.

Why we run our own DoH resolver?

There are already some public DNS resolvers like 1.1.1.1 and 9.9.9.9 that support DNS over HTTPS, so you can use them. Starting with Firefox version 61, you can enable DNS over HTTPS in the browser settings, which is a big progress for Internet security and privacy. Firefox uses Cloudflare resolvers (1.1.1.1) by default. However, some folks argue that this allows Cloudflare (and others) to gather information on you. They seem to have more trust in their ISP than Cloudflare. But I think if you are paranoid about privacy, you should run your own DoH resolver with your own CA or just use “our’s” so neither Cloudflare nor your ISP can spy on you. I’m pretty sure here, the government agencies have direct access to the public DNS from those popular services. I can confirm, ISP’s have the government “black boxes” installed!

DoH vs DoT

Besides DNS over HTTPS, there’s another protocol that also aims to encrypt DNS queries. It’s called DNS over TLS (DoT).It’s more advantageous to use DoH.- DoT operates on TCP port 853, which can be easily blocked by a national firewall. - DoH operates on TCP port 443, which is the standard port for HTTPS websites, which makes DoH super hard (almost impossible) to block, because if TCP port 443 is blocked, then nearly all HTTPS websites will also be blocked. Another advantage of DoH is that it allows web applications to access DNS information via existing browser APIs, so no stub resolver is needed.Here you'll find more information and how to setup DoH  Read the full article

Making Sense of the Mess: LLMs Role in Unstructured Data Extraction

New Post has been published on https://thedigitalinsider.com/making-sense-of-the-mess-llms-role-in-unstructured-data-extraction/

Making Sense of the Mess: LLMs Role in Unstructured Data Extraction

Recent advancements in hardware such as Nvidia H100 GPU, have significantly enhanced computational capabilities. With nine times the speed of the Nvidia A100, these GPUs excel in handling deep learning workloads. This advancement has spurred the commercial use of generative AI in natural language processing (NLP) and computer vision, enabling automated and intelligent data extraction. Businesses can now easily convert unstructured data into valuable insights, marking a significant leap forward in technology integration. 

Traditional Methods of Data Extraction 

Manual Data Entry 

Surprisingly, many companies still rely on manual data entry, despite the availability of more advanced technologies. This method involves hand-keying information directly into the target system. It is often easier to adopt due to its lower initial costs. However, manual data entry is not only tedious and time-consuming but also highly prone to errors. Additionally, it poses a security risk when handling sensitive data, making it a less desirable option in the age of automation and digital security. 

Optical Character Recognition (OCR)  

OCR technology, which converts images and handwritten content into machine-readable data, offers a faster and more cost-effective solution for data extraction. However, the quality can be unreliable. For example, characters like “S” can be misinterpreted as “8” and vice versa.  

OCR’s performance is significantly influenced by the complexity and characteristics of the input data; it works well with high-resolution scanned images free from issues such as orientation tilts, watermarks, or overwriting. However, it encounters challenges with handwritten text, especially when the visuals are intricate or difficult to process. Adaptations may be necessary for improved results when handling textual inputs. The data extraction tools in the market with OCR as a base technology often put layers and layers of post-processing to improve the accuracy of the extracted data. But these solutions cannot guarantee 100% accurate results.  

Text Pattern Matching 

Text pattern matching is a method for identifying and extracting specific information from text using predefined rules or patterns. It’s faster and offers a higher ROI than other methods. It is effective across all levels of complexity and achieves 100% accuracy for files with similar layouts.  

However, its rigidity in word-for-word matches can limit adaptability, requiring a 100% exact match for successful extraction. Challenges with synonyms can lead to difficulties in identifying equivalent terms, like differentiating “weather” from “climate.”Additionally, Text Pattern Matching exhibits contextual sensitivity, lacking awareness of multiple meanings in different contexts. Striking the right balance between rigidity and adaptability remains a constant challenge in employing this method effectively. 

Named Entity Recognition (NER)  

Named entity recognition (NER), an NLP technique, identifies and categorizes key information in text. 

NER’s extractions are confined to predefined entities like organization names, locations, personal names, and dates. In other words, NER systems currently lack the inherent capability to extract custom entities beyond this predefined set, which could be specific to a particular domain or use case. Second, NER’s focus on key values associated with recognized entities does not extend to data extraction from tables, limiting its applicability to more complex or structured data types. 

 As organizations deal with increasing amounts of unstructured data, these challenges highlight the need for a comprehensive and scalable approach to extraction methodologies. 

Unlocking Unstructured Data with LLMs 

Leveraging large language models (LLMs) for unstructured data extraction is a compelling solution with distinct advantages that address critical challenges. 

Context-Aware Data Extraction 

LLMs possess strong contextual understanding, honed through extensive training on large datasets. Their ability to go beyond the surface and understand context intricacies makes them valuable in handling diverse information extraction tasks. For instance, when tasked with extracting weather values, they capture the intended information and consider related elements like climate values, seamlessly incorporating synonyms and semantics. This advanced level of comprehension establishes LLMs as a dynamic and adaptive choice in the domain of data extraction.  

Harnessing Parallel Processing Capabilities 

LLMs use parallel processing, making tasks quicker and more efficient. Unlike sequential models, LLMs optimize resource distribution, resulting in accelerated data extraction tasks. This enhances speed and contributes to the extraction process’s overall performance.  

Adapting to Varied Data Types 

While some models like Recurrent Neural Networks (RNNs) are limited to specific sequences, LLMs handle non-sequence-specific data, accommodating varied sentence structures effortlessly. This versatility encompasses diverse data forms such as tables and images. 

Enhancing Processing Pipelines 

The use of LLMs marks a significant shift in automating both preprocessing and post-processing stages. LLMs reduce the need for manual effort by automating extraction processes accurately, streamlining the handling of unstructured data. Their extensive training on diverse datasets enables them to identify patterns and correlations missed by traditional methods. 

Source: A pipeline on Generative AI

This figure of a generative AI pipeline illustrates the applicability of models such as BERT, GPT, and OPT in data extraction. These LLMs can perform various NLP operations, including data extraction. Typically, the generative AI model provides a prompt describing the desired data, and the ensuing response contains the extracted data. For instance, a prompt like “Extract the names of all the vendors from this purchase order” can yield a response containing all vendor names present in the semi-structured report. Subsequently, the extracted data can be parsed and loaded into a database table or a flat file, facilitating seamless integration into organizational workflows. 

Evolving AI Frameworks: RNNs to Transformers in Modern Data Extraction 

Generative AI operates within an encoder-decoder framework featuring two collaborative neural networks. The encoder processes input data, condensing essential features into a “Context Vector.” This vector is then utilized by the decoder for generative tasks, such as language translation. This architecture, leveraging neural networks like RNNs and Transformers, finds applications in diverse domains, including machine translation, image generation, speech synthesis, and data entity extraction. These networks excel in modeling intricate relationships and dependencies within data sequences. 

Recurrent Neural Networks 

Recurrent Neural Networks (RNNs) have been designed to tackle sequence tasks like translation and summarization, excelling in certain contexts. However, they struggle with accuracy in tasks involving long-range dependencies.  

 RNNs excel in extracting key-value pairs from sentences yet, face difficulty with table-like structures. Addressing this requires careful consideration of sequence and positional placement, requiring specialized approaches to optimize data extraction from tables. However, their adoption was limited due to low ROI and subpar performance on most text processing tasks, even after being trained on large volumes of data. 

Long Short-Term Memory Networks 

Long Short-Term Memory (LSTMs) networks emerge as a solution that addresses the limitations of RNNs, particularly through a selective updating and forgetting mechanism. Like RNNs, LSTMs excel in extracting key-value pairs from sentences,. However, they face similar challenges with table-like structures, demanding a strategic consideration of sequence and positional elements.  

 GPUs were first used for deep learning in 2012 to develop the famous AlexNet CNN model. Subsequently, some RNNs were also trained using GPUs, though they did not yield good results. Today, despite the availability of GPUs, these models have largely fallen out of use and have been replaced by transformer-based LLMs. 

Transformer – Attention Mechanism 

The introduction of transformers, notably featured in the groundbreaking “Attention is All You Need” paper (2017), revolutionized NLP by proposing the ‘transformer’ architecture. This architecture enables parallel computations and adeptly captures long-range dependencies, unlocking new possibilities for language models. LLMs like GPT, BERT, and OPT have harnessed transformers technology. At the heart of transformers lies the “attention” mechanism, a key contributor to enhanced performance in sequence-to-sequence data processing. 

The “attention” mechanism in transformers computes a weighted sum of values based on the compatibility between the ‘query’ (question prompt) and the ‘key’ (model’s understanding of each word). This approach allows focused attention during sequence generation, ensuring precise extraction. Two pivotal components within the attention mechanism are Self-Attention, capturing importance between words in the input sequence, and Multi-Head Attention, enabling diverse attention patterns for specific relationships.  

In the context of Invoice Extraction, Self-Attention recognizes the relevance of a previously mentioned date when extracting payment amounts, while Multi-Head Attention focuses independently on numerical values (amounts) and textual patterns (vendor names). Unlike RNNs, transformers don’t inherently understand the order of words. To address this, they use positional encoding to track each word’s place in a sequence. This technique is applied to both input and output embeddings, aiding in identifying keys and their corresponding values within a document.  

The combination of attention mechanisms and positional encodings is vital for a large language model’s capability to recognize a structure as tabular, considering its content, spacing, and text markers. This skill sets it apart from other unstructured data extraction techniques.

Current Trends and Developments 

The AI space unfolds with promising trends and developments, reshaping the way we extract information from unstructured data. Let’s delve into the key facets shaping the future of this field. 

Advancements in Large Language Models (LLMs) 

Generative AI is witnessing a transformative phase, with LLMs taking center stage in handling complex and diverse datasets for unstructured data extraction. Two notable strategies are propelling these advancements: 

Multimodal Learning: LLMs are expanding their capabilities by simultaneously processing various types of data, including text, images, and audio. This development enhances their ability to extract valuable information from diverse sources, increasing their utility in unstructured data extraction. Researchers are exploring efficient ways to use these models, aiming to eliminate the need for GPUs and enable the operation of large models with limited resources.

RAG Applications: Retrieval Augmented Generation (RAG) is an emerging trend that combines large pre-trained language models with external search mechanisms to enhance their capabilities. By accessing a vast corpus of documents during the generation process, RAG transforms basic language models into dynamic tools tailored for both business and consumer applications.

Evaluating LLM Performance 

The challenge of evaluating LLMs’ performance is met with a strategic approach, incorporating task-specific metrics and innovative evaluation methodologies. Key developments in this space include: 

Fine-tuned metrics: Tailored evaluation metrics are emerging to assess the quality of information extraction tasks. Precision, recall, and F1-score metrics are proving effective, particularly in tasks like entity extraction.

Human Evaluation: Human assessment remains pivotal alongside automated metrics, ensuring a comprehensive evaluation of LLMs. Integrating automated metrics with human judgment, hybrid evaluation methods offer a nuanced view of contextual correctness and relevance in extracted information.

Image and Document Processing  

Multimodal LLMs have completely replaced OCR. Users can convert scanned text from images and documents into machine-readable text, with the ability to identify and extract information directly from visual content using vision-based modules. 

Data Extraction from Links and Websites 

LLMs are evolving to meet the increasing demand for data extraction from websites and web links These models are increasingly adept at web scraping, converting data from web pages into structured formats. This trend is invaluable for tasks like news aggregation, e-commerce data collection, and competitive intelligence, enhancing contextual understanding and extracting relational data from the web. 

The Rise of Small Giants in Generative AI 

The first half of 2023 saw a focus on developing huge language models based on the “bigger is better” assumption. Yet, recent results show that smaller models like TinyLlama and Dolly-v2-3B, with less than 3 billion parameters, excel in tasks like reasoning and summarization, earning them the title of “small giants.” These models use less compute power and storage, making AI more accessible to smaller companies without the need for expensive GPUs. 

Conclusion 

Early generative AI models, including generative adversarial networks (GANs) and variational auto encoders (VAEs), introduced novel approaches for managing image-based data. However, the real breakthrough came with transformer-based large language models. These models surpassed all prior techniques in unstructured data processing owing to their encoder-decoder structure, self-attention, and multi-head attention mechanisms, granting them a deep understanding of language and enabling human-like reasoning capabilities. 

 While generative AI, offers a promising start to mining textual data from reports, the scalability of such approaches is limited. Initial steps often involve OCR processing, which can result in  errors, and challenges persist in extracting text from images within reports.  

 Whereas, extracting text inside the images in reports is another challenge. Embracing solutions like multimodal data processing and token limit extensions in GPT-4, Claud3, Gemini offers a promising path forward. However, it’s important to note that these models are accessible solely through APIs. While using APIs for data extraction from documents is both effective and cost-efficient, it comes with its own set of limitations such as latency, limited control, and security risks.  

 A more secure and customizable solution lies in fine tuning an in-house LLM. This approach not only mitigates data privacy and security concerns but also enhances control over the data extraction process. Fine-tuning an LLM for document layout understanding and for grasping the meaning of text based on its context offers a robust method for extracting key-value pairs and line items. Leveraging zero-shot and few-shot learning, a finetuned model can adapt to diverse document layouts, ensuring efficient and accurate unstructured data extraction across various domains.

Amazon Route 53 Advanced Features for Global Traffic

What is Amazon Route 53

A dependable and economical method of connecting end users to Internet applications

Sharing and then assigning numerous DNS resources to each Amazon Virtual Private Cloud (Amazon VPC) can be quite time-consuming if you are managing numerous accounts and Amazon VPC resources. You may have even gone so far as to create your own orchestration layers in order to distribute DNS configuration throughout your accounts and VPCs, but you frequently run into limitations with sharing and association.

Amazon Route 53 Resolver DNS firewall

With great pleasure, AWS now provide Amazon Route 53 Profiles, which enable you to centrally manage DNS for all accounts and VPCs in your company. Using Route 53 Profiles, you may apply a standard DNS configuration to several VPCs in the same AWS Region. This configuration includes Amazon Route 53 private hosted zone (PHZ) associations, Resolver forwarding rules, and Route 53 Resolver DNS Firewall rule groups. You can quickly and simply verify that all of your VPCs have the same DNS setup by using Profiles, saving you the trouble of managing different Route 53 resources. It is now as easy to manage DNS for several VPCs as it was for a single VPC.

Because Profiles and AWS Resource Access Manager (RAM) are naturally connected, you can exchange Profiles between accounts or with your AWS Organizations account. By enabling you to create and add pre-existing private hosted zones to your Profile, Profiles effortlessly interacts with Route 53 private hosted zones. This means that when the Profile is shared across accounts, your organizations will have access to the same settings. When accounts are initially provisioned, AWS CloudFormation enables you to utilize Profiles to define DNS settings for VPCs regularly. You may now more effectively manage DNS settings for your multi-account environments with today’s release.

Amazon Route 53 benefits

Automatic scaling and internationally distributed Domain Name System (DNS) servers ensure dependable user routing to your website

Amazon Route 53 uses globally dispersed Domain Name System (DNS) servers to provide dependable and effective end-user routing to your website. By dynamically adapting to changing workloads, automated scaling maximises efficiency and preserves a flawless user experience.

Use cases

Control network traffic worldwide

Easy-to-use global DNS features let you create, visualize, and scale complicated routing interactions between records and policies.

Construct programmes that are extremely available

In the event of a failure, configure routing policies to predetermine and automate responses, such as rerouting traffic to different Availability Zones or Regions.

Configure a private DNS

In your Amazon Virtual Private Cloud, you can assign and access custom domain names (VPC). Utilise internal AWS servers and resources to prevent DNS data from being visible to the general public.

Which actions can you perform in Amazon Route 53

The operation of Route 53 Profiles

You go to the AWS Management Console for Route 53 to begin using the Route 53 Profiles. There, you can establish Profiles, furnish them with resources, and link them to their respective VPCs. Then use AWS RAM to share the profile you made with another account.

To set up my profile, you select Profiles from the Route 53 console’s navigation pane, and then you select Create profile.

You will optionally add tags to my Profile configuration and give it a pleasant name like MyFirstRoute53Profile.

The Profile console page allows me to add new Resolver rules, private hosted zones, and DNS Firewall rule groups to my account or modify the ones that are already there.

You select which VPCs to link to the Profile. In addition to configuring recursive DNSSEC validation the DNS Firewalls linked to my VPCs’ failure mode, you are also able to add tags. Additionally, you have the ability to decide which comes first when evaluating DNS: Profile DNS first, VPC DNS second, or VPC DNS first.

Up to 5,000 VPCs can be linked to a single Profile, and you can correlate one Profile with each VPC.

You can control VPC settings for different accounts in your organization by using profiles. Instead of setting them up per-VPC, you may disable reverse DNS rules for every VPC that the Profile is connected to. To make it simple for other services to resolve hostnames from IP addresses, the Route 53 Resolver automatically generates rules for reverse DNS lookups on my behalf. You can choose between failing open and failing closed when using DNS Firewall by going into the firewall’s settings. Additionally, you may indicate if you want to employ DNSSEC signing in Amazon Route 53 (or any other provider) in order to enable recursive DNSSEC validation for the VPCs linked to the Profile.

Assume you can link a Profile to a VPC. What occurs when a query precisely matches a PHZ or resolver rule that is linked to the VPC’s Profile as well as one that is related with the VPC directly? Which DNS settings, those from the local VPCs or the profiles, take priority? In the event that the Profile includes a PHZ for example.com and the VPC is linked to a PHZ for example.com, the VPC’s local DNS settings will be applied first. The most specific name prevails when a name query for a conflicting domain name is made (for instance, the VPC is linked to a PHZ with the name account1.infra.example.com, while the Profile has a PHZ for infra.example.com).

Using AWS RAM to share Route 53 Profiles between accounts

You can share the Profile you made in the previous part with my second account using AWS Resource Access Manager (RAM).

On the Profiles detail page, you select the Share profile option. Alternatively, you may access the AWS RAM console page and select Create resource share.

You give your resource share a name, and then you go to the Resources area and look for the “Route 53 Profiles.” You choose the Profile under the list of resources. You have the option to add tags. Next is what you select.

RAM controlled permissions are used by profiles, enabling me to assign distinct permissions to various resource types. The resources inside the Profile can only be changed by the Profile’s owner, the network administrator, by default. Only the contents of the Profile (in read-only mode) will be accessible to the recipients of the Profile, which are the VPC owners. The resource must have the required permissions attached to it in order for the Profile’s recipient to add PHZs or other resources to it. Any resources that the Profile owner adds to the shared resource cannot be edited or removed by recipients.

You choose to allow access to my second account by selecting Next, leaving the default settings.

You select Allow sharing with anyone on the following screen, type in the ID of my second account, and click Add. Next, You select that account ID under Selected Principals and click Next.

You select Create resource share on the Review and create page. The creation of the resource sharing is successful.

You, now navigate to the RAM console using your other account, which you share your profile with. You select the resource name you generated in the first account under the Resource sharing section of the navigation menu. You accept the offer by selecting Accept resource share.

And that’s it! now select the Profile that was shared with you on your Amazon Route 53Profiles page.

The private hosted zones, Resolver rules, and DNS Firewall rule groups of the shared profile are all accessible to you. You are able to link this Profile to the VPCs for this account. There are no resources that you can change or remove. As regional resources, profiles are not transferable between regions.

Amazon Route 53 availability

Using the AWS Management Console, Route 53 API, AWS CloudFormation, AWS Command Line Interface (AWS CLI), and AWS SDKs, you can quickly get started with Route 53 Profiles.

With the exception of Canada West (Calgary), the AWS GovCloud (US) Regions, and the Amazon Web Services China Regions, Route 53 Profiles will be accessible in every AWS Region.
