CloudFormation3
- Control AWS infrastructure in predictable way (infrastructure as code)
- You don’t need to figure out the order for provisioning of AWS services
- no additional charge- JSON-formatted template (Declarative style)- By default, “automatic rollback on error” feature is
enabled. Stacks can be fully created, or not at all.
AWS Test Drive
AWS Test Drive - sandbox containing preconfigured server based solutions. Using a step-by-step lab manual and video, launch, login and learn about these popular 3rd party IT solutions, powered by AWS and CloudFormation.

Stack
Stack - collection of AWS resources that result from instantiating a template. Stack = template + input parameters

Bootstrapping ApplicationsPython helper scripts (preinstalled on Amazon Linux AMI in /opt/aws/bin):1. cfn-get-metadata: Retrieve metadata (key-value) attached to resources in
the template.2. cfn-init: install packages and files described in AWS::CloudFormation::Init.3. cfn-signal: signal to the stack creation workflow that your application is
ready to take traffic. Signal an CloudFormation CreationPolicy or WaitCondition
4. cfn-hup: daemon to listen for stack updates and execute hooks to react to those changes.
You can use CloudFormation scripts on their own or in conjunction with CloudInit (official Ubuntu EC2 AMI support it).

Applications23
Create new environment - step 1 24
Worker Tier25
step 2 - Application26
Ways to deploy Docker app1. Create a Dockerfile to deploy a Docker container to
AWS Elastic Beanstalk.2. Create a Dockerrun.aws.json file to deploy a Docker
container from an existing Docker image3. Create a .zip file containing any application file
dependencies, the Dockerfile or Dockerrun.aws.json
