Modern DevOps Practices

By: Gaurav Agarwal

Overview of this book

Containers have entirely changed how developers and end-users see applications as a whole. With this book, you'll learn all about containers, their architecture and benefits, and how to implement them within your development lifecycle. You'll discover how you can transition from the traditional world of virtual machines and adopt modern ways of using DevOps to ship a package of software continuously. Starting with a quick refresher on the core concepts of containers, you'll move on to study the architectural concepts to implement modern ways of application development. You'll cover topics around Docker, Kubernetes, Ansible, Terraform, Packer, and other similar tools that will help you to build a base. As you advance, the book covers the core elements of cloud integration (AWS ECS, GKE, and other CaaS services), continuous integration, and continuous delivery (GitHub actions, Jenkins, and Spinnaker) to help you understand the essence of container management and delivery. The later sections of the book will take you through container pipeline security and GitOps (Flux CD and Terraform). By the end of this DevOps book, you'll have learned best practices for automating your development lifecycle and making the most of containers, infrastructure automation, and CaaS, and be ready to develop applications using modern tools and techniques.

Introduction to Spinnaker

Spinnaker is an open source, multi-cloud continuous delivery tool developed by Netflix and Google and which was then open sourced to the Cloud Native Computing Foundation (CNCF). This tool can help you deploy your applications across multiple clouds and Kubernetes clusters and manage them using a single control plane. That provides organizations with immense power in managing their deployments across several estates, geographical locations, and cloud accounts.

The tool is potent and flexible with its pipelines. Currently, it supports many target cloud platforms, including AWS EC2, EKS, Kubernetes, Google Compute Engine, Google Kubernetes Engine, Google App Engine, Microsoft Azure, Openstack, Oracle Cloud Infrastructure, and Cloud Foundry. They also have plans to integrate it with on-premises data centers.

It helps you run robust deployment pipelines that can run system and integration tests, manage your infrastructure using a concept called server groups...
