Architecture

The architecture diagram for this problem is as shown below

Running Instructions

• To set up the server, you have to first create the network infrastrcture using the command:

./create.sh udagram-famisa-infra infra.yml infra-params.json

Note: udagram-famisa-infra could be substituted with any name of your choice.

• After a CREATE_COMPLETE status update on your AWS CloudFormation console, you then need to create the servers using the command:

./create.sh udagram-famisa-server server.yml server-params.json

Note: udagram-famisa-server could be substituted with any name of your choice.

• After another CREATE_COMPLETE on the server stack, click on the Outputs tab of the server stack, and there you will find DNS name to test this app as value to the key: LoadBalancerDNSName

Important files:

• create.sh, update.sh & delete.sh
• infra.yml - AWS CloudFormation script for setting up network infrastructure - subnets, internet gateway, VPC, private subnets, etc. Corresponding parameters file is infra-params.json
• server.yml - AWS CloudFormation script for setting up server infrastructure and IAM roles. Corresponding parameters file is server-params.json

Remember to call ./delete.sh <stack-name> to delete resources to avoid incurring charges
