. What is Kubernetes?
As the definition says, Kubernetes or k8s is an open source orchestration and cluster management for container-based applications maintained by the Cloud Native Computing Foundation. The official kubernetes website (k8s
Kubernetes is an open source system for automating the deployment, scaling, and management of containerized applications. Group the containers that make up an application into logical units for easy management and discovery. Kubernetes is based on 15 years of experience running production workloads at Google, combined with community insights and practices.
In simple words, kubernetes makes it easy to manage containers across multiple hosts. Plus, it makes container deployment a breeze with a declarative YAML file. You specify how you want the container to be deployed, and Kubernetes takes care of it by reading the information provided in the YAML.
Why do we need Kubernetes?
Kubernetes is used to automate the deployment, scaling, and management of containerized applications. It provides an open source platform for orchestration and automation of containerized workloads and services.
Kubernetes allows you to easily scale applications, self-healing, and continuous updates, making it suitable for running microservices and distributed systems
The first question when it comes to Kubernetes or a container orchestrator is why we need it. Let’s understand it from two real-world examples.
Suppose you have a pair of Java applications. You can package it in a container and run it on a server that contains a Docker engine or any container engine. For this scenario, there is no complexity.
You can package your application into a Docker image using Dockerfile and expose a port on a host for the external world to access.
However, the downside is that it can be a single point of failure, as it only runs on a single server. To handle the single point of failure, you need an efficient mechanism.
That’s why you need a container clustering and orchestration tool like Kubernetes to scale applications on demand and withstand single-node failures.
let’s say, you have a great application that is made up of microservices (API, user interface, user management, credit card transaction system, etc.). All of these microservices components have to communicate with each other using REST APIs or other protocols.
Because the application has many components or microservices, we cannot deploy all services on one server or container. Applications must be decoupled, and each microservice must deploy and scale on its own. This makes application development and deployment easier and faster.
In this scenario, the complexity lies in networking, shared file systems, load balancing, and service discovery. This is where Kubernetes comes into the picture. It helps orchestrate complex processes in a manageable way.
With kubernetes, you only have to worry about the development and deployments of your applications. Kubernetes takes care of all the heavy lifting, such as networking, service-to-service communication between nodes, load balancing, resource scheduling, scalability, and high availability.
Overall, Kubernetes helps you achieve the following.
- Automatic container scheduling
- Scale-up and scale-up
- Continuous application upgrades and downgrades with no downtime
