• Considering you have proper installations for minikube and kubernetes!, No? -> refer this minikube and kubernetes

Architecture

What is happening here?

• You know, fibonacci number?, we will be calucating the fibonnaci number on the index given
• 
• We will be using an ingress image to capture input from the end user and later on, will serve them to our express server and react clients
• 
• So the postgres will store all the indexes the user or server has seen before
• The redis will take the index and stores it in her database
• The worker node will contact redis and calcuates the value for the index stored in redis and updates the value in redis db
• The calcualated and the seen indexes are shown in our frontend
• The PVC [persistent volume claim] is something that provides persistant data to the postgres deployments (one word: disaster recovery)
•
