Kubernetes in Production Best Practices

By: Aly Saleh, Murat Karslioglu

Overview of this book

Although out-of-the-box solutions can help you to get a cluster up and running quickly, running a Kubernetes cluster that is optimized for production workloads is a challenge, especially for users with basic or intermediate knowledge. With detailed coverage of cloud industry standards and best practices for achieving scalability, availability, operational excellence, and cost optimization, this Kubernetes book is a blueprint for managing applications and services in production. You'll discover the most common way to deploy and operate Kubernetes clusters, which is to use a public cloud-managed service from AWS, Azure, or Google Cloud Platform (GCP). This book explores Amazon Elastic Kubernetes Service (Amazon EKS), the AWS-managed version of Kubernetes, for working through practical exercises. As you get to grips with implementation details specific to AWS and EKS, you'll understand the design concepts, implementation best practices, and configuration applicable to other cloud-managed services. Throughout the book, you’ll also discover standard and cloud-agnostic tools, such as Terraform and Ansible, for provisioning and configuring infrastructure. By the end of this book, you’ll be able to leverage Kubernetes to operate and manage your production environments confidently.

Preparing for backups and disaster recovery

In this section, we will be taking a complete, instant, or scheduled backup of the applications running in our cluster. Not every application requires or can even take advantage of regular backups. Stateless application configuration is usually stored in a Git repository and can be easily deployed as part of the Continuous Integration and Continuous Delivery (CI/CD) pipelines when needed. Of course, this is not the case for stateful applications such as databases, user data, and content. Our business running online services can be challenged to meet legal requirements and industry-specific regulations and retain copies of data for a certain time.

For reasons external or internal to our clusters, we can lose applications or the whole cluster and may need to recover services as quickly as possible. In that case, for disaster recovery use cases, we will learn how to use our backup data stored in an S3 target location to restore services...
