This is a repository, conatining cloudformation scripts to deploy a highly available web application on Amazon Web Services platform. This repository was made, as a part of my Nanodegree project with Udacity.

The architecture diagram has been provided in the repository, in the name of WebApp.jpeg. I used a Website, named Lucid.com to design my own Achitecture diagram.

Here are some of the requirements, to run these scripts on your local machine:

1. Download a text editor like Microsoft Visual Studio Code. Link to download Microsoft Visual Studio Code: https://code.visualstudio.com/
2. Set up an Amazon Web Services account. Here's link to create your AWS account: https://portal.aws.amazon.com/billing/signup#/start
3. Set AWS Command Line Interface on your device. Download AWS CLI tool using the link: https://aws.amazon.com/cli/.
4. Use the following command in your command prompt or terminal of your VS Code to set-up your AWS account. $ aws configure
5. Follow the steps to create Access Key and Secret Access Key in IAM, using the following link: https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html#cli-quick-configuration

1. Downlaod Create command file and Update command file into the same working directory, as the CloudFormation Scripts.
2. Make sure that, the present working directory of your VS Code terminal, be same as the directory, where scripts are present.
3. Now, to depoy/create the cloud formation stack, write command: $ ./create.sh <name-of-the-stack> <name-of-the-template-flie-in-yml> <name-of-the-parameters-file-in-json>
4. Make sure, to first deply WebApp-Network.yml infrastruture, before deploying WebApp.yml scripts. And make sure to run WebApp-Network-Paramters.json with WebApp-Network.yml and WebApp-Paramters.json with WebApp.yml.
5. To update the created stack, run the following command: $ ./update.sh <name-of-the-stack> <name-of-the-template-flie-in-yml> <name-of-the-parameters-file-in-json>
6. You can check AWS console, and go AWS Cloud Fomation to check if your cloud formation stack has been deployed, or not.
7. If the stack dosen't get deployed, check the logs of CloudFormation stack, to check for the error in script.
