In today’s world of complex, web-scale application backends made up of many microservices and components running across clusters of servers and containers, managing and coordinating all these pieces is incredibly challenging.
That’s where Kubernetes comes in. Kubernetes (also known as “k8s”) is an open-source container orchestration platform that automates deployment, scaling, and management of containerized applications.
With Kubernetes, you don’t have to worry about manually placing containers or restarting failed ones. You simply describe your desired application architecture and Kubernetes makes it happen and keeps it running.
We’ll dive deep into Kubernetes and cover:
We’ll demystify Kubernetes and equip you with everything you need to determine if and when Kubernetes could be the right solution for your applications. You’ll walk away with a clear understanding of what Kubernetes is, how it works, and how to put it into practice.
Whether you’re a developer, ops engineer, or technology leader, you’ll find invaluable insights in this deep dive into Kubernetes.
Containers are a method of packaging and isolating applications into standardised units that can be easily moved between environments.
Unlike traditional virtual machines (VMs) which virtualise an entire operating system, containers only virtualise the application layer, making them more lightweight, portable and efficient.
Kubernetes was created and offers automated deployment, scaling, and management of containerised applications. Through the utilisation of containers instead of VMs, Kubernetes delivers advantages such as heightened resource efficiency, faster application deployment, and portability between on-premises and cloud environments.
The number 8 in k8s refers to the 8 letters between the first letter “k” and the last letter “s” in the word Kubernetes.
Containerisation has revolutionised the way applications are deployed and managed. However, deploying and managing multiple containers across a cluster of machines can quickly become complex. This is where Kubernetes comes in. Kubernetes abstracts the underlying infrastructure and provides a unified API and control plane for managing containers, making it easier to deploy, scale, and monitor applications.
Some key benefits of using Kubernetes include:
