If you’re an active reader of this blog, you probably have more than just a surface understanding of the growth of cloud native architectures, DevOps, containers and the benefits of Kubernetes. However, with VMworld 2021 upon us, we frequently hear requests from long-time VMware customers and users who are just starting out their Kubernetes journey, looking to understand the various flavors of VMware Tanzu and Kasten by Veeam’s support for data protection on the various Tanzu platforms and offerings.
A (Very) Short History Lesson in Virtualization, Containers and Kubernetes
It’s well-known that VMware has been a leading pioneer in server virtualization since the release of VMware Workstation 1.0 back in May of 1999, and the bare metal ESX hypervisor in March 2001. Server virtualization quickly became the de facto model for scalable applications in on-premises data centers, and the backbone for cloud computing.
Around 2011 or so, a company emerged by the name of Docker that made a technology from 2008 called LXC, short for “Linux Containers,” mainstream. Containers are a way of packaging up applications in a similar way as a virtual machine packages computing resources, but without the need of a host operating system such as Windows or Linux. This allows a “containerized” application to be much more lightweight, secure and easily scalable, as you only need to include the important bits of the application and none of the host OS. The growth of Docker’s popularity and the use of containers started a fundamental shift in the way applications are developed, deployed and scaled.
Why the Shift?
Containerized workloads offer significant benefits to customers of all sizes, as an Analysis by VMware indicates. These benefits increase business velocity while reducing the cost of operations -- a significant advantage for businesses on their digital transformation journey.
As containers became more ubiquitous within development operations, container orchestration and management became necessary. A project started by Google called “Kubernetes,” Greek for "helmsman," eventually became the winner in the race for container management systems around 2018, and thereafter became the backbone for services such as Amazon’s EKS and Microsoft Azure’s AKS container management systems.
Enter VMware Tanzu
VMware dove head-first into the Kubernetes space through a series of acquisitions (Pivotal, Heptio, Bitnami), which became the foundation of a Kubernetes-focused portfolio of products with the moniker “Tanzu.”

In 2019, VMware introduced a re-architecture of VMware vSphere with Kubernetes as its control plane -- and so began the journey to manage cloud resources such as virtual machines, disks and networks. As a result, managing containerized applications instead of individual VMs was possible, accelerating the development of modern apps. Leveraging Kubernetes-native APIs to access resources such as compute, networking and storage helped IT teams rapidly provision and provide resources for development and scalable operations.
Tanzu Kubernetes Grid and vSphere with Tanzu
Where things get a bit murky for those dipping their toes into the Tanzu pool is where to draw a distinction between the two major “flavors” of Tanzu that are available today. To understand the fundamental differences, think of the different editions of Tanzu Kubernetes running on versus in a vSphere environment:
- Tanzu “On” vSphere: VMware Tanzu Kubernetes Grid, or simply TKG, and TKG-multicloud (TKGm) are upstream Kubernetes distributions with binaries that are tested, signed, and supported by VMware. Because TKG runs as standard Linux based VMs, TKG/TKGm fall into the category of running on vSphere platforms. The node VMs run alongside traditional VMs for a more flexible environment that hasn’t been totally dedicated to Kubernetes. TKG/TKGm is supported on vSphere 6.7u3 and newer. Other distributions of Kubernetes that run on vSphere and fall into this category are Red Hat OpenShift, Suse Rancher and Amazon EKS Anywhere.

- Tanzu “In” vSphere: vSphere with Tanzu (or sometimes referred to as Tanzu Kubernetes Grid Service) creates a Kubernetes control plane directly in the hypervisor layer, making it tightly coupled into the vSphere UI itself, including vCenter SSO, the Content Library, vSphere networking, vSphere storage, vSphere HA and DRS and vSphere security. Ultimately, this lets you create, operate and manage Tanzu Kubernetes clusters natively and seamlessly in vSphere. The latest version vSphere with Tanzu is only supported on vSphere 7.0u2 and newer.

Where Kasten K10 Lands on Tanzu
Though this shift to a more DevOps view of application management is compelling, it’s important to understand the impact of Kubernetes on backup and recovery. Some of the features that make Kubernetes a powerful application deployment environment can also create new challenges when it comes to managing and protecting your data.
Implementing Kubernetes-native backup for your applications is critical to protect your data in the event of an accident, system failure, or even a deliberate attack. With a proper native backup strategy in place, you’ll feel more confident when utilizing the powerful, yet complex Kubernetes platform.
Kasten K10 by Veeam is fully validated and supported on Tanzu Kubernetes Grid and other upstream Kubernetes distributions that run “on” vSphere. Kasten K10 has native vSphere integrations for persistent volume data protection with the vSphere CSI provider. Kasten has worked closely with VMware to tightly integrate its Kubernetes-native data management capabilities with VMware's Cloud Native Storage (CNS) constructs and First Class Disks (FCDs), to optimize backups with capabilities such as Change Block Tracking (CBT).

So what changes with Tanzu Kubernetes Grid Service from a data protection technology perspective? Traditional vCenter API and CSI interaction doesn’t work quite the same with the tightly integrated control plane. New APIs for data protection are being worked on to allow third-party Kubernetes-native data protection apps such as Kasten K10 to be able to call vSphere native snapshots and directly access the underlying disk resources required for proper data protection. We also see a growing and diverse set of data services and applications in this Kubernetes-native environment that need protection at a logical level.

Integrating Backup Into Your GitOps CI/CD Pipeline [CODE2809]
The ability to deploy code and version code has been a de facto requirement, and a reason we have CI/CD pipelines for our application development. But with Kubernetes, in particular, we are seeing a closer tie between code and data. Code being deployed can affect and change your data, and for that reason, we need to consider protecting data as part of our Continuous Development pipelines. In this session, we will focus on how we can incorporate backup actions into your pipeline to ensure that any code changes will start by creating a restore point, be it a snapshot or an export to another external repository. We will then demo a failure scenario into the environment pipeline, to simulate how a configmap can manipulate data to cause data loss. Then we need a way to bring the data back!
