It is ex. Based on the recent release of Kubernetes 1. The book focuses on core Kubernetes constructs, such as pods, services, replica sets, replication controllers, and labels. Traditional relational databases that give life — or state — to any application were no t architectured to take full advantage of the resources available in the cloud.
A new breed of relational databases — Distributed SQL databases — hav e emerged over the past few years and are able to take full advantage of the cloud and the operational benefits provided by Kubernetes. To read the entire Refcard, please download the PDF from the link above. It automates the deployment, scaling, and management of services and applications. This capability, while seemingly s imple, delivers huge value to organizations , especially as they scale out their cloud-native initiatives and have to manage and operate hundreds or thousands of services.
It delivers a wide range of capabilities that help keep apps and services up and running to scale individual services and meet user demand. A s a direct descendant of Borg the Google internal orchestration platform , Kubernetes brings Google-like power to operations.
It simplifies and eases delivery for applications architected to take advantage of the resources available in cloud environments. Every public cloud provider offers Kubernetes as a platform.
Before we get into the framework for evaluating to what extent a database is Kubernetes-native, it is important first to understand why state and storage are still issues in Kubernetes. By definition, databases are considered stateful applications. Kubernetes, on the other hand, was originally intended to facilitate the management of stateless applications connected to external services to store state, if necessary. The guaran tees which Kubernetes offers — for example , high availability of services — were premised on the idea that the underlying pods were effectively ephemeral and interchangeable.
Kubernetes manages containers dynamically, meaning that individua l containers may be brought up or taken down at any time to match the needs of the application as a whole. This works fine for stateless services, but a stateful, persistent service like a database cannot afford to be restarted arbitrarily. In the past, de velopers often chose to run databases outside Kubernetes, which was problematic because it required redundant infrastructure management tools for the external database, such as monitoring and service discovery.
