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.

Working with alerts

Any monitoring tool is not complete if it does not have a good alerting capability. Aria is also not an exception. It has a very powerful and highly configurable alerting engine that allows you to configure alerts with multiple thresholds, delivery based on those threshold levels, and several possible delivery methods, including but not limited to an email, a text, a Slack message, a Microsoft Teams message, a ServiceNow ticket, or a PagerDuty incident. Moreover, we can also configure triggering an automated process using a webhook that calls a remote API outside of the Aria boundary. There are so many useful things we can configure using Aria’s alerting features. Let’s learn more about alerts in this section, including the following things:

  • Creating alert targets to define who should get which alert using which delivery mechanism
  • Defining a maintenance window to avoid obvious alerts
  • Creating new alerts
  • Inspecting firing alerts
  • ...
