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.

Why Spring Cloud Gateway for Kubernetes?

Spring Cloud Gateway for Kubernetes is based on the open source Spring Cloud Gateway project: https://spring.io/projects/spring-cloud-gateway. Spring Cloud Gateway is a library for building high-performance APIs. You deploy it like a normal Spring app and configure it like you would configure a Spring app. Unfortunately, the open source project doesn’t do much to address many of the problems mentioned previously – problems commonly encountered in the enterprise.

In addition to their business logic, developers must also package, configure, and deploy a Spring Cloud Gateway app, or bundle it into their existing app as a library. Either way, it’s a significant amount of added complexity. Unless they’re using some advanced features of the Spring Framework, any changes to their API’s routes will involve rebuilding and redeploying the app.

Furthermore, the open source Spring Cloud Gateway leaves some of the...
