Kubernetes Deployment Example

What is Kubernetes?

Kubernetes is a container orchestration tool that is used to deploy, scale, and manage containerized applications. Kubernetes follows a master-slave architecture. The master node manages all the cluster operations while the worker node deploys and runs the containers. The master node consists of 4 main components, API Server which helps in interacting and giving commands to the Kubernetes cluster, Scheduler schedules the pod on a particular node for running, etc. to stores the Kubernetes cluster data and control managers for managing the different controllers like deployment, replica sets and many more. On the other hand, in the worker node, there is Kubelet which helps in managing the pod lifecycle, container runtime which helps in running the containers and Kube proxy which manages all the networking rules in the pods....

What is Nginx?

NGINX is an open-source web service tool used mainly for reverse proxying, caching, and load balancing. Using NGINX reduces the loading time of a website. NGINX improves the overall user experience. It can also handle concurrent requests. NGINX provides better performance and scalability. NGINX can be used in microservice, where it can be used as a reverse proxy to protect the backend servers from direct exposure to the outside world. This results in reducing any potential attack. NGINX consumes fewer resources compared to other server software and is compatible with a variety of web applications which makes it a better cost-effective solution. In summary, we can say NGINX is a powerful tool that is used by various organizations for faster loading of web applications and also to handle a large number of requests....
