Kubernetes is hot and everyone loses their minds

We all witnessed Pat Gelsinger invite Kubernetes to vSphere and all of a sudden every IT manager on the planet needs to have a Kubernetes strategy. There are many facets to understanding and embracing Kubernetes as the platform of the future coming from a traditional IT mindset. Are we ready?

Forgetting IaaS

With the recent announcement from SUSE to abandon OpenStack in favor of their container offerings, where are we going to run these containers? Kubernetes does not replace the need to effectively provision infrastructure resources. We need abstractions to provision servers, networks and storage to run the Kubernetes clusters on. The public cloud vendors obviously understands this but are we simply giving the hybrid cloud market to VMware? Is vSphere the only on-prem IaaS that will matter down the line? Two of the biggest cloud vendors rely on VMware for their hybrid offerings. Google Anthos and Amazon Outpost.

Rise Above

In the new brave world IT staff needs to start thinking drastically different on how they manage and consume resources. New tools need to be honed to make developers productive (and first and foremost, happy) and not have them run off with shadow IT. There’s an apparent risk that we’ll leapfrog from one paradigm to another without understanding the steps necessary in between to embrace Kubernetes.

Since my first KubeCon in 2016 I immediately understood that Kubernetes is going to become the defacto "operating system” for multi-node computing. There’s nothing you can’t do on Kubernetes you did yesterday with headless applications. It gives you way too much for free. Why would you be stuck in imperative patterns with toil overload when the declarative paradigm is readily available for your developers and operations team?

Start now Mr. IT Manager

Do not sit around and wait for Tanzu and Project Pacific to land in your lap. There are plenty of Kubernetes distributions with native integration with vSphere that allow your teams to exercise the patterns required to be successful at deploying and running K8s in a production setting.

Here’s a non-exhaustive list with direct links to the vSphere integration of each:

IaC Sights into IBM Cloud Edge VPC Deployable Architecture

VPC Management

An examination of the IaC features of the edge VPC using deployable architecture on IBM Cloud. Many organizations now find themselves forced to create a secure and customizable virtual private cloud (VPC) environment within a single region due to the constantly changing nature of cloud infrastructure. This need is met by the VPC landing zone deployable architectures, which provide a collection of initial templates that may be easily customized to meet your unique needs.

Utilizing Infrastructure as Code (IaC) concepts, the VPC Landing Zone deployable architecture enables you to describe your infrastructure in code and automate its deployment. This method facilitates updating and managing your edge VPC setup while also encouraging uniformity across deployments.

The adaptability of the VPC Landing Zone is one of its main advantages. The starting templates are simply customizable to meet the unique requirements of your organisation. This can entail making changes to security and network setups as well as adding more resources like load balancers or block volumes. You may immediately get started with the following patterns, which are starter templates.

Edge VPC setup

Pattern of landing zone VPCs: Installs a basic IBM Cloud VPC architecture devoid of any computational resources, such as Red Hat OpenShift clusters or VSIs.

QuickStart virtual server instances (VSI) pattern: In the management VPC, a jump server VSI is deployed alongside an edge VPC with one VSI.

QuickStart ROKS pattern: One ROKS cluster with two worker nodes is deployed in a workload VPC using the Quick Start ROKS pattern.

Virtual server (VSI) pattern: In every VPC, deploys the same virtual servers over the VSI subnet layer.

Red Hat Open Shift pattern: Every VPC’s VSI subnet tier has an identical cluster deployed per the Red Hat Open Shift Kubernetes (ROKS) design.

VPC Patterns that adhere to recommended standards

To arrange and oversee cloud services and VPCs, establish a resource group.

Configure Cloud Object Storage instances to hold Activity Tracker data and flow logs.

This makes it possible to store flow logs and Activity Tracker data for a long time and analyze them.

Keep your encryption keys in situations of Key Protect or Hyper Protect Crypto Services. This gives the management of encryption keys a safe, convenient location.

Establish a workload VPC for executing programmes and services, and a management VPC for monitoring and controlling network traffic.

Using a transit gateway, link the workload and management VPCs.

Install flow log collectors in every VPC to gather and examine information about network traffic. This offers visibility and insights on the performance and trends of network traffic.

Put in place the appropriate networking rules to enable VPC, instance, and service connectivity.

Route tables, network ACLs, and security groups are examples of these.

Configure each VPC’s VPEs for Cloud Object Storage.

This allows each VPC to have private and secure access to Cloud Object Storage.

Activate the management VPC VPN gateway.

This allows the management VPC and on-premises networks to communicate securely and encrypted.

Patterns of landing zones

To acquire a thorough grasp of the fundamental ideas and uses of the Landing Zone patterns, let’s investigate them.

First, the VPC Pattern

Being a modular solution that provides a strong base upon which to develop or deploy compute resources as needed, the VPC Pattern architecture stands out. This design gives you the ability to add more compute resources, such as Red Hat OpenShift clusters or virtual private islands (VSIs), to your cloud environment. This method not only makes the deployment process easier, but it also makes sure that your cloud infrastructure is safe and flexible enough to meet the changing demands of your projects.

The VSI pattern QuickStart with edge VPC

Deploying an edge VPC with a load balancer inside and one VSI in each of the three subnets is the Quickstart VSI pattern pattern. It also has a jump server VSI that exposes a public floating IP address in the management VPC. It’s vital to remember that this design, while helpful for getting started quickly, does not ensure high availability or validation within the IBM Cloud for Financial Services framework.

ROKS pattern QuickStart

A security group, an allow-all ACL, and a management VPC with a single subnet make up the Quickstart ROKS pattern pattern. The Workload VPC features a security group, an allow-all ACL, and two subnets located in two distinct availability zones. There is a Transit Gateway that connects the workload and management VPCs.

In the workload VPC, a single ROKS cluster with two worker nodes and an enabled public endpoint is also present. The cluster keys are encrypted using Key Protect for further protection, and a Cloud Object Storage instance is configured as a prerequisite for the ROKS cluster.

Pattern of virtual servers

Within the IBM Cloud environment, the VSI pattern architecture in question facilitates the establishment of a VSI on a VPC landing zone. One essential part of IBM Cloud’s secure infrastructure services is the VPC landing zone, which is made to offer a safe platform for workload deployment and management. For the purpose of building a secure infrastructure with virtual servers to perform workloads on a VPC network, the VSI on VPC landing zone architecture was created expressly.

Pattern of Red Hat OpenShift

The architecture of the ROKS pattern facilitates the establishment and implementation of a Red Hat OpenShift Container Platform in a single-region configuration inside a VPC landing zone on IBM Cloud.

This makes it possible to administer and run container apps in a safe, isolated environment that offers the tools and services required to maintain their functionality.

Because all components are located inside the same geographic region, a single-region architecture lowers latency and boosts performance for applications deployed within this environment.

It also makes the OpenShift platform easier to set up and operate.

Organizations can rapidly and effectively deploy and manage their container apps in a safe and scalable environment by utilizing IBM Cloud’s VPC landing zone to set up and manage their container infrastructure.
