You must have used the word " **Kubernetes**" so many times on the internet.

> Applications running in containers may self-heal thanks to Kubernetes, making them resistant to unforeseen failures. The best possible use of cloud resources may be achieved using Kubernetes' ability to automatically scale containerized apps based on workload. Kubernetes significantly streamlines the deployment procedure.

These lines definitely satisfy the power of Kubernetes if you know "**[Kubernetes](https://kubernetes.io/)**" well; otherwise, Kubernetes is just an orchestration tool. So let's start

Google created the open-source container-orchestration technology known as Kubernetes or K8s for short. It is utilized for orchestrating, or grouping and controlling, clusters of containerized applications, which is an " **orchestration**" in the computer industry. ![image.png](https://cdn.hashnode.com/res/hashnode/image/upload/v1660232542867/N0TOTghWK.png)

## Software design and its demand

Before we proceed, taking a step back could be beneficial. The old method of developing software involved taking the many features, logic, and services that make up an application and combining them into a single program. However, this [monolithic architecture](https://www.techtarget.com/whatis/definition/monolithic-architecture) lacked the flexibility to meet the constantly evolving demands of the contemporary software business.

Making precise code modifications may become more difficult as your program expands. You'll have to redeploy it if it requires upgrading, resulting in downtime and costing you money. Fixing a defect in service could make your entire program crash. inaccessible to users. Scaling one service could interfere with other services.

The [microservices architecture](https://microservices.io/) overcomes these challenges. Your application's services may be virtualized using containers and are loosely connected using microservices. Different services may be individually coded, deployed, updated, and maintained. You can also scale up or down depending on your application's demands. However, this necessitates maintaining track of hundreds or even thousands of containers.

## Container Technology

As we know, the most effective way to deploy applications is using containers, which has numerous advantages, but you still need to manage your containers to avoid downtime. Kubernetes is the perfect tool to help you accomplish that.

To better understand Kubernetes, you first have to understand why container technology and products like [Docker](https://www.docker.com/) are so popular. Virtual machines can be replaced with containers in a way that is more efficient and less expensive. In essence, they enable you to bundle a service such that you may execute it on your laptop or in a production setting with little modification and fairly predictable outcomes.

After your application has successfully run on a computer, you must choose how to automate it. It might become too much to handle manually when you have a lot of containers to manage. In this situation, Kubernetes could be useful.

You may easily operate tens or hundreds of instances as opposed to only one container instance. You will begin to see significant advantages in relation to your workflow as you gradually implement this. You'll be able to use Kubernetes' features to write software in a more flexible, decentralized way, in addition to having a more effective way to deploy products.

> Kubernetes will provide you with the ability to move more quickly, have fewer disruptions, and make better use of your resources as the demands on your infrastructure increase.

## Important Use Cases & Benefits

- **Ability to run anywhere** : You can run Kubernetes on-premises or in a public, private, or hybrid cloud without modifying your application or your infrastructure. It gives the container an isolated environment so that it can be easily replicated wherever it requires.
- **Scaling handling** : Based on application load and resource limit Kubernetes handles the autoscaling of containers.
- **Self-healing** : In many cases, containers might die with unfortunate circumstances, Kubernetes rollout auto restarts and keeps containers
- **Service discovery and load balancing** : It provides support to dynamically changing behavior or container and provides stability for unseen traffic load. 
- **Secret and configuration management** : With Kubernetes, you can update authentication credentials, like passwords, application keys, and SSH keys, and keep them secure.

## TL;DR

Kubernetes, which roughly translates to "pilot" in Greek, refers to a trustworthy guide who can securely guide you to your goal. The Google developers responsible for the platform's nomenclature and design gave careful consideration to both.

For workloads and services that are containerized, Kubernetes is a potent solution. It alters the way programs are deployed and gives you access to a number of tools that make managing numerous containers easier. As your business expands, Kubernetes will help you effectively handle the complexities of the current software development landscape.
