Example: what is aws

Amazon Web Services (AWS) is a secure cloud services platform,
offering compute power, database storage and it helps Running 
web and application servers 
in the cloud to host dynamic websites.

in my company We use; 

EC2: 
   - for Running application for different environments(Test, Dev enviroments).
   - and also for Running Jenkins or any other application for testing purpose.
   - and to Run load testing on the application.
We also use S3 (Simple Storage Service):
  - It is Used for file storage, test data storage.
  - It Can be used for part of data processing workflow.
  - and also it Can also be used as code repository.

IAM (Identity and Access Management) is a web service that helps you 
securely control access to AWS resources. You use IAM to control who is 
authenticated (signed in) and authorized (has permissions) to use resources.
   - I use IAM for Permission control of users, applications, typically 
   not configured by application team but by a cloud team.
RDS (Create a sample Postgresql database and connect using Dbeaver):
   - is Used for database, launch database for different environments to 
   support the application.
Lambda:
   - Serverless service that can provide quick and easy solution to run 
   your code without the involvement of EC2.
   - Typically used for data processing incoming files.
