*Migration of large monolithic application to microservice architecture in aws.>we were tasked with migrating a large monolithic application to a microservices architecture on AWS. This was a challenging deployment because the application had been built over several years and was tightly coupled to the underlying infrastructure.>First, we created a Terraform configuration which defined our new architecture. This included setting up VPCs, subnets, security groups and EC2 instances.We then used Ansible to deploy our microservices to the EC2 instances. We decided to use Ansible because it allowed us to automate not only the deployment of the code but also the configuration of the underlying infrastructure.>We also used Docker to containerize our application which made it easier to deploy and maintain.One of the biggest challenges we faced was how to migrate our data from the monolithic application to the new microservices infrastructure. We decided to use AWS Database Migration Service to move our data from our old Oracle database to an Aurora PostgreSQL database.>The deployment took longer than expected, but we were eventually able to successfully migrate the application to the microservices architecture. We were able to reduce our infrastructure costs by 50% and saw a 40% improvement in our application's performance.*containerizing e-commerce company application>As a part of the DevOps team at an e-commerce company that needs to deploy a new microservices-based application. The application consists of several components, including a user service, product service, order service, and payment service. Each service is containerized using Docker, and the company wants to ensure scalability, high availability, and efficient management of these services.ObjectiveThe objective is to deploy, manage, and scale the e-commerce application using Docker for containerization and Kubernetes for orchestration.
