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.

How to perform key day-2 operations on Tanzu Service Mesh

At this point, we have a distributed application successfully working across two Kubernetes clusters. If you were doing this in a real production environment, there are some day-2 concerns you’d want to address. For example, it’s great that the catalog service can run on a separate cluster, but what if that cluster goes down? How could we load balance across instances on multiple clusters?

Furthermore, we’re living in a world where deployment, upkeep, measuring, and monitoring of services are often the responsibility of Site Reliability Engineers (SREs). If you were the SRE for Acme Fitness, you would have already identified Service-Level Indicators (SLIs) and defined SLOs for your services. Tanzu Service Mesh greatly simplifies this by allowing you to define your SLIs and SLOs right in the Tanzu Service Mesh UI and measure how your services are meeting those SLOs using real-time metrics.
