Deploy Scalable Website on AWS

Deploy a high availability and scalable WordPress website securely on AWS Cloud using Route 53, CloudFront, Load Balancers, Auto Scaling Groups, Target Groups, Launch Templates, AWS Certificate Manager, Amazon Machine Images (AMIs), EC2, EFS, RDS, CloudWatch Logs, VPC. We could Launch EC2 in a private Subnet without a Public IP but for this, We needed to use a NAT gateway which is very expensive, So, I skipped this & launched EC2 in a public subnet under a Load Balancer but in more secure way.

Containerize MERN application with Docker Compose

For the dockerize a full stack web MERN application using docker-compose we create separate ‘Dockerfile’ for the frontend (client) & backend (server) to create a docker image and we use MongoDB official docker imager for containerizing and defining their configurations in a docker-compose.yml file. in these configurations, we know variation topics of Docker and docker-compose like Docker environment, volume, etc.
