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.

Learning application deployment strategies

Organizations without the expertise to design an application deployment strategy before getting their services to production users can face great operational complexity when managing their application life cycle. Many users still face container and microservices adoption issues later in their digital transformation journey and end up going back to the more expensive Database as a Service (DbaaS) model or even using traditional deployment methods in VMs. To avoid common mistakes and production anti-patterns, we need to be aware of some of the common strategies that will ensure our success in deploying and managing applications on Kubernetes.

We learned about the differences between different Kubernetes controllers such as Deployments, ReplicaSets, and StatefulSets in the Deploying stateful applications section in Chapter 7, Managing Storage and Stateful Applications.

In this section, we will learn about the following containerized application...
