Benefits of using Kubernetes

Why Kubernetes?

To understand why we need Kubernetes we need to first understand Containers. Once we have our application in various containers, we will now have to manage these Containers to ensure that the application is available to its users without any downtime. The key feature of containers is that they’re small and light enough that we use them within our development environment. Using containers within our development environment gives us high confidence that our production environment is as similar as possible to that development environment....

Benefits of using Kubernetes

Kubernetes has tons of advantages when it comes to container orchestration. The benefits of Kubernetes depend of who is using it and how, but some of the most important features or benefits provided by Kubernetes are as follows:...

1. High Availability and Scalability

(i) High Availability...

How does Kubernetes Achieve it?

For Example, we have two worker nodes of Kubernetes Cluster – Server one and Server two. Each of these server is holding a replica of an application called “my app” and a database application. We also have an ingress component which basically handles every incoming request to the application so if someone accessed “my app” website on a browser, the request would come in to ingress. Ingress is load-balanced so we have replicas of ingress on multiple servers. Ingress will forward that request to the Service for my application. Service is a load balancer that will direct that request to the respective replicas of the Pod....

2. Disaster Recovery

Disaster recovery as the name suggests is set of practices to ensure that operations are restored after any disruption happens in our deployment system. This disruption could be system failures, natural disasters, or human errors....

3. Easier Replication

Replication simply means creating copies of the application so that the application can be scaled. Upon creating multiple replicas of an application, the request coming to it can be divided among these replicas and this is how the application can be scaled....

4. Self Healing

In terms of deployment, Self healing is a feature that allows the system to notice if there are any failures or issues in the system and automatically recover it without needing any intervention from the administrator....

5. Smart Scheduling

In Kubernetes, Smart Scheduling is a feature that provides an advanced approach for the scheduling of tasks where we as administrators only have to add new replicas and Kubernetes automatically figures out where these replicas should be running....

Conclusion

Kubernetes has a tons of advantages when it comes to container orchestration. It is the most widely used container orchestration tool across industries. It offers features like High availability, high scalability, smart scheduling, smart healing and much more. Make sure to go though these features, it will really help you understand why Kubernetes has came out as an industry standard....
