Single User Flow

• User creates a project
• The new project creates a web-socket connection
• The new code is saved to DynamoDB (every 5 secs) and periodically to S3

Multiple User Flow

• User logs in
• User invites another user to the project
• New user recieves an email and accepts it
• Now the user is a collaborator for the project
• The new user is added to the web-socket room and the changes from both users are synced
• The new code is saved to DynamoDB (every 5 secs) and periodically to S3

Code execution

• User logs in
• User runs the code (async, gets response immediately. loading icon on FE)
• Docker container with the required base image is created on EC2 instance

• DB is polled from the frontend
