Tanzu Application Platform is a modular, composable platform that comprises the following components.
API portal for VMware Tanzu enables API consumers to find APIs they can use in their own applications.
Consumers can view detailed API documentation and try out an API to see if it meets their needs. API portal assembles its dashboard and detailed API documentation views by ingesting OpenAPI documentation from the source URLs. An API portal operator can add any number of OpenAPI source URLs to to appear in a single instance.
The Application Accelerator component helps app developers and app operators create application accelerators.
Accelerators are templates that codify best practices and ensure important configurations and structures are in place from the start. Developers can bootstrap their applications and get started with feature development right away.
Application operators can create custom accelerators that reflect their desired architectures and configurations and enable fleets of developers to use them. This helps ease operator concerns about whether developers are implementing their best practices.
Application Live View is a lightweight insight and troubleshooting tool that helps application developers and application operators look inside running applications.
It is based on the concept of Spring Boot Actuators. The application provides information from inside the running processes by using endpoints (in our case, HTTP endpoints). Application Live View uses those endpoints to get the data from the application and to interact with it.
Application Single Sign-On enables application users to sign in to their identity provider once and be authorized and identified to access any Kubernetes-deployed workload. It is a secure and straightforward approach for developers and operators to manage access across all workloads in the enterprise.
Cloud Native Runtimes for Tanzu is a serverless application runtime for Kubernetes that is based on Knative and runs on a single Kubernetes cluster. For information about Knative, see the Knative documentation. Cloud Native Runtimes capabilities are in VMware Tanzu Advanced Edition and VMware Tanzu Application Platform.
The convention service provides a means for people in operational roles to express their hard-won knowledge and opinions about how apps run on Kubernetes as a convention. The convention service applies these opinions to fleets of developer workloads as they are deployed to the platform, saving time for operators and developers.
This package includes five default roles for users, including app-editor, app-viewer, app-operator, and service accounts including workload and deliverable. These roles are available to help operators limit permissions a user or service account requires on a cluster that runs Tanzu Application Platform. They are built by using aggregated cluster roles in Kubernetes role-based access control (RBAC).
Default roles only apply to a user interacting with the cluster by using kubectl and Tanzu CLI. Tanzu Application Platform GUI support for default roles is planned for a future release.
Developer conventions configure workloads to prepare them for inner loop development.
It’s meant to be a “deploy and forget” component for developers. After it is installed on the cluster with the Tanzu Package CLI, developers do not need to directly interact with it. Developers instead interact with the Tanzu Developer Tools for VSCode IDE Extension or Tanzu CLI Apps plug-in, which rely on the Developer Conventions to edit the workload to enable inner loop capabilities.
Eventing for VMware Tanzu focuses on providing tooling and patterns for Kubernetes applications to manage event-triggered systems through Knative Eventing. For information about Knative, see the Knative documentation.
The main role of this source management component is to provide a common interface for artifact acquisition.
Grype is a vulnerability scanner for container images and file systems.
Services Toolkit comprises a number of Kubernetes-native components that support the management, life cycle, discoverability, and connectivity of Service Resources (databases, message queues, DNS records, and so on) on Kubernetes.
Supply Chain Choreographer is based on open-source Cartographer. It enables app operators to create preapproved paths to production by integrating Kubernetes resources with the elements of their existing toolchains, such as Jenkins.
Each pre-approved supply chain creates a paved road to production. It orchestrates supply chain resources, namely test, build, scan, and deploy. Enabling developers to focus on delivering value to their users. Pre-approved supply chains also assure application operators that all code in production has passed through the steps of an approved workflow.
With Supply Chain Security Tools for VMware Tanzu - Scan, you can build and deploy secure trusted software that complies with their corporate security requirements.
To enable this, Supply Chain Security Tools - Scan provides scanning and gate keeping capabilities that Application and DevSecOps teams can incorporate earlier in their path to production. This is an established industry best practice for reducing security risk and ensuring more efficient remediation.
Supply Chain Security Tools - Policy is an admission controller that allows a cluster operator to specify policies to verify image container signatures before admitting them to a cluster. It works with cosign signature format and allows for fine-tuned configuration of policies based on image source patterns.
Supply Chain Security Tools - Store saves software bills of materials (SBoMs) to a database and enables you to query for image, source, package, and vulnerability relationships. It integrates with SCST - Scan to automatically store the resulting source and image vulnerability reports.
Tanzu Application Platform GUI lets your developers view your organization’s running applications and services. It provides a central location for viewing dependencies, relationships, technical documentation, and even service status. Tanzu Application Platform GUI is built from the Cloud Native Computing Foundation’s project Backstage.
Tanzu Build Service uses the open-source Cloud Native Build packs project to turn application source code into container images.
Build Service executes reproducible builds that align with modern container standards and keeps images up to date. It does so by leveraging Kubernetes infrastructure with kpack, a Cloud Native Build packs Platform, to orchestrate the image life cycle.
The kpack CLI tool, kp, can aid in managing kpack resources. Build Service helps you develop and automate containerized software workflows securely and at scale.
Tanzu Developer Tools for Visual Studio Code is the official VMware Tanzu IDE extension for VS Code to help you develop code by using Tanzu Application Platform. The VS Code extension enables live updates of your application while it runs on the cluster and lets you debug your application directly on the cluster.
Learning Center provides a platform for creating and self-hosting workshops. With Learning Center, content creators can create workshops from markdown files that learners can view in a terminal shell environment with an instructional wizard UI. The UI can embed slide content, an integrated development environment (IDE), a web console for accessing the Kubernetes cluster, and other custom web applications.
Although Learning Center requires Kubernetes to run, and it teaches users about Kubernetes, you can use it to host training for other purposes as well. For example, you can use it to train users on web-based applications, use of databases, or programming languages.
Tekton is a powerful and flexible open-source framework for creating CI/CD systems, enabling developers to build, test, and deploy across cloud providers and on-premise systems.
Note: You can opt out of telemetry collection by following the instructions in Opting out of telemetry collection.
You can deploy Tanzu Application Platform through predefined profiles, each containing various packages, or you can install the packages individually. The profiles allow Tanzu Application Platform to scale across an organization’s multicluster, multi-cloud, or hybrid cloud infrastructure. These profiles are not meant to cover all use cases, but serve as a starting point to allow for further customization.
