Everything about Kubernetes
What is Kubernetes?
Kubernetes (often referred to as k8s for short) is an open source platform that automates Linux container operations. Containers can help to improve application performance and reliability by packaging code into standalone packages. Each container includes everything needed to run an application and can be launched reliably from multiple computing environments.
The core benefit of Kubernetes is removes the burden of repetitive, manual processes involved in scaling ‘containerized’ applications. Kubernetes is ideal for cloud applications that need to scale quickly on-demand (for example, streaming services).
Kubernetes was created by engineers at Google. The concept of containerization allows Google to provide their services to millions around the world every day. In fact, the company generates more than 2 billion container deployments using their internal container tool, Borg. Borg provided the blueprint for Kubernetes and influenced the design and development of the software.
Kubernetes explained – why should I use it?
Kubernetes allows you to cluster groups of hosts running in Linux containers.These clusters can be used in private, public or hybrid clouds. It enables users to manage those containers efficiently and effectively. Kubernetes enables you to run distributed systems. This can help to ensure uptime and scale with demand. For instance, if one container fails another container is launched automatically to serve the application. If you suddenly get a spike in traffic, Kubernetes can launch more containers to handle the increased demand (also known as Kubernetes autoscaling).
Getting started with Kubernetes? You can find in-depth tutorials on the official Kubernetes site.
To extend and update Kubernetes functionality, you can use the dedicated package manager called Helm. Helm is actively maintained by global companies such as Google, Microsoft and Bitnami.
Docker is a platform built to help manage the containerization of applications. It provides a secure and flexible environment that works with Kubernetes out-of-the-box. Docker claims the added benefits of easy onboarding, enterprise-readiness and integration possibilities.
AWS Kubernetes (EKS)
You can also run Kubernetes on AWS. Amazon EKS – which stands for Elastic Kubernetes Service – allows you to run Kubernetes without needing to install your own clusters. AWS also provides community-backed integrations to help you boost functionality, capability and security. Furthermore, AWS is itself a contributor to the Kubernetes codebase.
