First step towards the most popular application development framework for enterprise Java applications. When Spring came out it was “simpler,light-weight alternative to J2EE, to make J2EE development easier”.

About Terraform : With Terminal a few bytes of code and no SSH logins we can spin up in minute , a production ready cluster and a capable of heavy work loads and here it comes “Terraform” — an extremely powerful tool written in “Go” that helps us “writing ,planing and creating stateful reproducible infrastructure as code”.
Terraform by HashiCorp an orchestration tool for “building,changing and versioning infrastructure safely and efficiently” that allows to represent instances and other resources with declarative code inside configuration files.(instead of manually creating those resources).
In Tradition IT World, there are limited number of servers to handle the application load.when the number of requests increases load on the server also increases, which cause failures and latency in system.
Amazon web service provide Amazon EC2 auto scaling services to overcome this failure.Auto Scaling ensures that Amazon EC2 instances are sufficient to run our application.
What is Amazon EC2 Auto Scaling ? — helps you to ensure that we have the correct number of ec2 instances available to handle the load of you application.
