Cloud Native with Kubernetes

By: Alexander Raul

Overview of this book

Kubernetes is a modern cloud native container orchestration tool and one of the most popular open source projects worldwide. In addition to the technology being powerful and highly flexible, Kubernetes engineers are in high demand across the industry. This book is a comprehensive guide to deploying, securing, and operating modern cloud native applications on Kubernetes. From the fundamentals to Kubernetes best practices, the book covers essential aspects of configuring applications. You’ll even explore real-world techniques for running clusters in production, tips for setting up observability for cluster resources, and valuable troubleshooting techniques. Finally, you’ll learn how to extend and customize Kubernetes, as well as gaining tips for deploying service meshes, serverless tooling, and more on your cluster. By the end of this Kubernetes book, you’ll be equipped with the tools you need to confidently run and extend modern applications on Kubernetes.

Running DBs on Kubernetes

Now that we've taken a look at object storage workloads on Kubernetes, we can move on to databases. As we've discussed previously in this chapter and elsewhere in the book, many databases support running on Kubernetes, with varying levels of maturity.

First off, there are several legacy and existing DB engines that support deploying to Kubernetes. Often, these engines will have supported Helm charts or operators. For instance, SQL databases such as PostgreSQL and MySQL have Helm charts and operators supported by various different organizations. NoSQL databases such as MongoDB also have supported ways to deploy to Kubernetes.

In addition to these previously existing database engines, container orchestrators such as Kubernetes have lead to the creation of a new category – the NewSQL database.

These databases offer the incredible scalability of NoSQL databases in addition to SQL-compliant APIs. They can be thought of as a way to easily...
