You need to create high-available micro-service under AWS.
Service has to listen on TCP port and return back to the client morse-code of clients IP address. AWS infrastructure have to
- be multi-region (f.e. us-east-1, eu-west-1, ap-southeast-1) and to respond from the nearest to client location
- be easy scalable
Answer should contain
- source code of micro-service
- terraform files or set of AWS cli instruction for the creation of infrastructure (if not all requirements are solvable by terraform - You shall describe additional steps)
- Clone repo
- Export AWS credentials:
export AWS_ACCESS_KEY_ID=""
export AWS_SECRET_ACCESS_KEY=""
export AWS_DEFAULT_REGION=""- Run terraform provision in terraform dir
terraform plan
terraform apply -auto-approve- Login to instances
- Clone repo to instances
- Run listener on instances
