This project allows users to use LLM model to create a learning path for themselves. Project contians both frontend and backend code which can be deployed to AWS services. Project contains cloudformation file which could be executed to create a stack and complete the deployment.

AWS Infrastructure

Compute

1. AWS EC2 - deploy frontend application

   1. create a simple instance with key pair
   2. add nvm "curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash"
   3. source ~/.bashrc
   4. nvm install --lts
   5. open ec2 instance using WinSCP
   6. transfer dist files to VM
   7. npm install -g serve
   8. nohup serve -l 3000 -s app-name

2. AWS Lambda - deploy backend api

   1. Create a lambda with Java 21 environment and upload jar, change timeout to 1 minute or more

Storage

   1. Create a table with id as partition key

Network

1. AWS API Gateway – Route API requests to lambdas
   1. Create a API gateway with REST type, and create a post endpoint with integration to lambda

General

1. AWS Secrets manager - used to store database credentials, API key for backend

   1. chatGptApiKey : **************
   2. tableName : cloud-term-assignment

2. AWS SES - used to send email

   1. Add two personal email as verified identities, one will be used to send email and one will be used to receive email
