-While you can use an existing "default" VPC to implement deployment of your genomics environment, we strongly recommend utilizing a VPC with private subnets for the processing sensitive data with AWS Batch. Doing so will restrict access to the instances from the internet, and help meet security and compliance requirements, such as [dbGaP](http://j.mp/aws-dbgap).

 The above template uses the AWS Quickstart reference for a [Modular and Scalable VPC Architecture](https://aws.amazon.com/quickstart/architecture/vpc/) and provides a networking foundation for AWS Cloud infrastructures, deploying an Amazon Virtual Private Cloud (Amazon VPC) according to AWS best practices and guidelines.
 
 For architectural details, best practices, step-by-step instructions, and customization options, see the [deployment guide](https://fwd.aws/9VdxN).

 The "Full Stack" CloudFormation template below will create all of the AWS resources required - S3 Bucket, EC2 Launch Templates, IAM Roles, Batch Compute Environments, Batch Job Queues - for your genomics workflow environment into an existing VPC.

+### Option B: Individual components
 
 The CloudFormation templates above are [nested stacks](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-nested-stacks.html), a hierarchy of templates that pass values from a parent template to dependent templates.
 
 Below are the stand-alone CloudFormation templates for S3, IAM, and AWS Batch. These are handy in case you need to modify the individual components, or need to have another individual with elevated privileges to execute one of them (e.g. the IAM template). They are in order of dependency, and you will need to provide output values from one template to the dependent templates.
