This is an assignment for the Udacity Devops Engineer Nanodegree program.
The task is to deploy an application (Apache Web Server) with high availability infrastructure. The website is hosted on servers within private subnets. All trafic to the servers is routed through Bastion located in one of the public subnet. Also, bastion functionality has been implemented for better secure access to instance via key pair. For high availability, project is tailored with leverage auto scaling parameters. Should not be any single point of failure. Also, the code (JavaScript and HTML) is pick up from S3 Storage and deploy it in the appropriate folder on the web server. NatGateways has been configured to allocate Elastic IP.
To deploy this infrastructure there is a helper script included in the repository. It can be used like this:
aws cloudformation create-stack --stack-name udagram-network --template-body file://udagram-network.yml --parameters file://udagram-network-parameters.json --region=us-west-2aws cloudformation create-stack --stack-name udagram-server --template-body file://udagram-server.yml --parameters file://udagram-server-parameters.json --region=us-west-2 --capabilities CAPABILITY_IAM
