And there is the storage enablement capabilities within pods to request and connect to storage. There is the Container Storage Interface (CSI) which is the connection point for storage systems. There are several key concepts that are important to understand for Kubernetes storage. Modern Kubernetes, however, is a different story and is fully capable of managing stateful applications and persistent storage. When Kubernetes was first developed, it was primarily used for stateless applications that did not have persistent storage requirements. Each pod gets its own IP address, network and storage resources

Node: Nodes in Kubernetes are the system resources that perform tasks as assigned by Kube master.Kube Master: This is the primary control point for distributed orchestration across different nodes.There are several key elements of any Kubernetes architecture The Kubernetes architecture is designed with replication and availability as a primary design element. Kubernetes Architecture: How Kubernetes Works This use of cloud native refers to applications – storage or otherwise – built specifically for the cloud, instead of built for the data center and later ported to the cloud. The portability also enables multicloud deployments, where Kubernetes is used to orchestrate container deployments in more than one cloud platform.Ĭloud-native is another term that is often directly associated with Kubernetes, thanks in part to the fact that it is the foundational project of the Cloud Native Computing Foundation (CNCF). The same basic Kubernetes container that runs in one public cloud can be run in another with little or no change. Kubernetes has become an important technology in recent years because of its portability. With Kubernetes, multiple sets of containers can be deployed, scaled and replicated for high-availability and application stability. The most commonly used form of application container with Kubernetes are Docker containers.

The effort moved to the Linux Foundation’s Cloud Native Computing Foundation (CNCF) in 2016 and is now a multi-stakeholder project, with support from all the major public cloud providers including Amazon Web Services, Microsoft Azure and Google Cloud.Īpplication containers are a way of packaging and delivering applications in a portable way. The Kubernetes platform was created by Google in 2014 as an open source effort to help manage its container deployment. That is, Kubernetes provides the services and management features that are necessary to deploy, operate and scale containers across a cluster or in a cloud computing environment. Kubernetes is a container orchestration platform.

Kubernetes allows developers to deploy and scale containers across a cluster or in a cloud computing environment. To be clear, while Kubernetes storage is sometimes used in the cloud, it is separate from cloud storage. With a properly implemented Kubernetes storage configuration, databases and application data can be created and accessed by many applications – allowing greater speed and efficiency. Kubernetes itself is a rapidly developing technology that has been embraced by cloud vendors and enterprises alike to enable a more agile and scalable form of application delivery. Kubernetes storage is useful to storage administrators because it enables different forms of persistent, stateful data retention within Kubernetes cluster deployments, which are increasingly popular.
