CT Infra Optimization Discussion

Create a DevOps infrastructure for an e-commerce application to run on high-availability mode.

Background of the problem statement:
A popular payment application, EasyPay where users add money to their wallet accounts, faces an issue in its payment success rate. The timeout that occurs with
the connectivity of the database has been the reason for the issue.
While troubleshooting, it is found that the database server has several downtime instances at irregular intervals. This situation compels the company to create their own infrastructure that runs in high-availability mode.
Given that online shopping experiences continue to evolve as per customer expectations, the developers are driven to make their app more reliable, fast, and secure for improving the performance of the current system.

Implementation requirements:

Create the cluster (EC2 instances with load balancer and elastic IP in case of AWS)
Automate the provisioning of an EC2 instance using Ansible or Chef Puppet
Install Docker and Kubernetes on the cluster
Implement the network policies at the database pod to allow ingress traffic from the front-end application pod
Create a new user with permissions to create, list, get, update, and delete pods
Configure application on the pod
Take snapshot of ETCD database
Set criteria such that if the memory of CPU goes beyond 50%, environments automatically get scaled up and configured

The following tools must be used:

EC2
Kubernetes
Docker
Ansible or Chef or Puppet

The following things to be kept in check:

You need to document the steps and write the algorithms in them.
The submission of your GitHub repository link is mandatory. In order to track your tasks, you need to share the link of the repository.
Document the step-by-step process starting from creating test cases, then executing them, and recording the results.
You need to submit the final specification document, which includes:

Project and tester details
Concepts used in the project
Links to the GitHub repository to verify the project completion
Your conclusion on enhancing the application and defining the USPs (Unique Selling Points)
