Architecture Diagram

The diagram above illustrates the architecture implemented by the CloudFormation code stored within the folder 'infrastructure'.

The architecture comprises of 4 different layers. Each layer is represented by a dedicated CloudFormation stack (and each stack can be created using provided bash script, YAML file and a param-file)

The 4 architectural layers (and the corresponding resources) are defined as follows:

• Layer-1: Subnets (Resources: Public and Private subnets, VPC)
• Layer-2: Internet (Resources: Internet Gateway and NAT Gateways)
• Layer-3: Security (Resources: Public and Private RouteTables)
• Layer-4: Servers (Resources: Load-Balancers, Server Launch Configurations).

For troubleshooting purposes, code for creating a Jumpbox CloudFormation stack is also provided.

To create the environment, the following commands can be used (in the exact order):

./script-create-stack.sh stack-subnet stack-subnet.yml param-subnet.json
./script-create-stack.sh stack-internet stack-internet.yml param-internet.json
./script-create-stack.sh stack-security stack-security.yml param-security.json
./script-create-instances.sh stack-server stack-server.yml param-server.json

Similarly, if needed, a jumpbox stack can be created:

./script-create-stack.sh stack-jumpbox stack-jumpbox.yml param-jumpbox.json

A number of utility scripts are also provided:

• script-list-outputs.sh >> to list all outputs
• script-list-stack-status.sh >> user friendly display of status of all running stacks
• script-delete-stack.sh >> to delete existing stack
• script-validate.sh >> to validate a YAML template for any syntax or formatting error
