+We eat, drink, sleep and most importantly love **DevOps**. We are working towards strategies for standardizing architecture while ensuring security for the infrastructure. We are strong believer of the philosophy <b>Bigger problems are always solved by breaking them into smaller manageable problems</b>. Resonating with microservices architecture, it is considered best-practice to run database, cluster, storage in smaller <b>connected yet manageable pieces</b> within the infrastructure. 
+
+This module is basically combination of [Terraform open source](https://www.terraform.io/) and includes automatation tests and examples. It also helps to create and improve your infrastructure with minimalistic code instead of maintaining the whole infrastructure code yourself.
+
+We have [*fifty plus terraform modules*][terraform_modules]. A few of them are comepleted and are available for open source usage while a few others are in progress.

+## Testing
+In this module testing is performed with [terratest](https://github.com/gruntwork-io/terratest) and it creates a small piece of infrastructure, matches the output like ARN, ID and Tags name etc and destroy infrastructure in your AWS account. This testing is written in GO, so you need a [GO environment](https://golang.org/doc/install) in your system.
