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.

Unboxing Aria

After understanding the reasons why and the use cases for which Aria can be a valuable tool to comprehensively monitor your cloud-native applications, let’s now learn more about the tool to understand what different data formats it can capture, its deployment architecture, and the building blocks that comprise this distributed system.

Supported data formats in Aria

The following is the list of different data formats that Aria can ingest and then use to generate useful charts, dashboards, and alerts.

Metrics

A metric is a small text-based record that carries the state data of a source being monitored at a specific timestamp. It may optionally have other tags for additional metadata that can be used to build useful queries for joins and filters. The most common form of metrics is time-series-based. We use it to report things such as the amount of a server’s memory occupied at any given point in time:
