DevSecOps in Practice with VMware Tanzu

By: Parth Pandit, Robert Hardt

Overview of this book

As Kubernetes (or K8s) becomes more prolific, managing large clusters at scale in a multi-cloud environment becomes more challenging – especially from a developer productivity and operational efficiency point of view. DevSecOps in Practice with VMware Tanzu addresses these challenges by automating the delivery of containerized workloads and controlling multi-cloud Kubernetes operations using Tanzu tools. This comprehensive guide begins with an overview of the VMWare Tanzu platform and discusses its tools for building useful and secure applications using the App Accelerator, Build Service, Catalog service, and API portal. Next, you’ll delve into running those applications efficiently at scale with Tanzu Kubernetes Grid and Tanzu Application Platform. As you advance, you’ll find out how to manage these applications, and control, observe, and connect them using Tanzu Mission Control, Tanzu Observability, and Tanzu Service Mesh. Finally, you’ll explore the architecture, capabilities, features, installation, configuration, implementation, and benefits of these services with the help of examples. By the end of this VMware book, you’ll have gained a thorough understanding of the VMWare Tanzu platform and be able to efficiently articulate and solve real-world business problems.

Spring Cloud Gateway for Kubernetes and API Portal for VMware Tanzu – overview

Before jumping into the product installation, let’s revisit why we’re here. I like to think of the API space in terms of three personas. There’s the API Developer, the API Consumer, and the API Operator. Each has its own set of problems.

If I develop APIs, there are some recurring problems that I must solve with every single project:

  • Exposing my API to my customers
  • Terminating TLS
  • Handling CORS and browser restrictions
  • Making my API discoverable
  • Securing my API endpoints so that only certain groups can execute certain functions
  • Protecting against misuse by rate-limiting requests
  • Rewriting request paths
  • Rewriting request and response headers

Transport Layer Security (TLS) is the cryptographic technology behind the reassuring lock next to your bank’s website’s URL in your web browser. It is especially...
