Tanzu guide: how it's changing the game for cloud-native apps

How times change. When the cloud was introduced in the mid-to-late 2000s, businesses used it in conjunction with on-premises servers. This represented an exciting yet uneasy mix of hardware and software, virtual and physical, the old and the new.

Fast forward to 2026 and more and more businesses are going cloud-native. Rather than migrating legacy systems, these cloud-based pioneers design, build and run applications specifically for the cloud.

This involves technologies such as containers, microservices and automation to create modular, flexible systems. Cloud-native cheerleaders point to the reliability, cost-effectiveness, scalability and creative dynamism this approach can bring.

These apps allow for automated updates with next to no downtime. Resources can be dynamically scaled within a highly secure infrastructure.

So far, so blue-sky. But the issue for developers and systems administrators has always been how to manage these cloud-native apps. Enter VMware Tanzu, a platform that's changing the game for cloud-native app management.

What is VMware Tanzu?

Let's start by looking at what Tanzu does. It acts as a comprehensive platform that simplifies Kubernetes and container orchestration.

It's "opinionated", meaning it enforces a specific and intentional approach to the building, deployment and management of applications – not just a neutral set of tools.

Best of all, it bridges the gap between code-focused developers and security-focused operators.

Tanzu gives all parties a consistent and reliable environment across complex cloud environments – from on-premise to the public cloud to edge infrastructures.

That's what it does – so what is it, exactly?

Put simply, VMware Tanzu is a portfolio of software, services and tools designed to build, run and manage cloud-native apps and Kubernetes clusters. It does this across private, public and multi-cloud environments.

Put even more simply, it's software that allows Kubernetes to run on vSphere.

Essential Tanzu features include:

Tanzu Platform (an opinionated platform-as-a-service)
Tanzu Kubernetes Grid (TKG)
Tanzu Application Service (TAS)
The central management hub, Tanzu Mission Control
Tanzu Hub, a console for visualising and managing complex app environments

How does VMware Tanzu manage containers?

In cloud computing, much is made of central consoles where complex environments can be built, run and managed. VMware Tanzu is one such console: a clear vantage point from which administrators can take care of Kubernetes-based containerised applications.

That clarity is all-important. VMware Tanzu takes disparate tools for cluster life cycle management, security policies and GitOps workflows and streamlines them. This enables developers and operators alike to manage consistent infrastructure.

Why does VMware Tanzu matter?

Tanzu is a powerful tool with three main benefits for enterprises looking to manage cloud-native apps.

First, it enables them to modernise legacy applications. Secondly, it speeds up the delivery of software, transforming monoliths into microservices with advanced automation tools.

And thirdly, it unifies operations across sprawling infrastructures. This means both developers and operators are on the same page and ready to do business.

More broadly, VMware Tanzu is ideal for organisations already using VMware tools and concepts. It allows them to transfer this expertise onto container management, rather than reskilling staff or starting from scratch.

Similarly, Tanzu Kubernetes Grid users get native support for vSphere resources. This allows you to leverage existing storage and data stores when creating storage classes.

What is a cloud-native app?

A cloud-native app is a piece of software specifically designed, built and operated for use in cloud computing. Unlike legacy apps, it's designed to leverage the full advantages of cloud environments, such as scalability, elasticity and resilience.

And unlike legacy apps, cloud-native apps use modern architectures. These include microservices, containers and automated orchestration such as Kubernetes. This enables them to rapidly deploy and update with minimal downtime.

What are microservices?

Microservices structure applications as a collection of small, independent and loosely coupled services. Each microservice handles a specific function.

These functions differ according to the nature of the business using microservices. In eCommerce, they might be product catalogue management or customer accounts. In banking, they might be fraud detection or payment processing.

Microservices communicate via lightweight application programming interfaces (APIs). These are deployed individually, allowing for faster development and scalability.

What are containers?

A container is a kind of skeleton key that allows an app to run consistently in different cloud computing environments. It does this independently of virtual machines.

Inside a container, you'll find an application's code along with its dependencies, libraries and configuration files – everything you need to run the app in any environment.

What is CI/CD?

CI/CD stands for "continuous integration / continuous delivery or deployment". It's a DevOps methodology that uses automation to build, test and deliver code changes.

Teams can merge code into a shared repository, meaning they can streamline the development life cycle, update process and bug detection.

VMware Tanzu accelerates CI/CD by automating application containerisation, testing and deployment across Kubernetes environments.

What is Tanzu Spring?

Formerly Tanzu Spring Runtime, Tanzu Spring provides support, security and maintenance for the open-source Spring ecosystem, Apache Tomcat and Java. This enables enterprises to stay

compliant while accelerating modernisation.

What is a golden path?

Sometimes referred to as a "paved path" or "paved road", a golden path is an opinionated and task-specific path for creating software. In practice, this means a smooth and speedy development process that's under the developer's control.

How we can help

Here at Ascend Cloud Solutions, we provide lab hosting services for VMware Education Delivery Partner (VEDP) courses. These include labs for two VEDP courses related to Tanzu:

These courses are suitable for vSphere administrators and platform operators. They presume knowledge of vSphere management and Kubernetes cluster architecture.
