Busy Task Available Task SSH Tunnel SQS Message

• Each Emulator Task has an SQS Listener polling for new session requests

• Available tasks compete for messages using SQS visibility timeout

1. Client EC2 Task sends request to API Gateway with SSH tunnel config

2. API Gateway publishes session request message to SQS queue

3. Available Emulator Tasks poll SQS queue for new requests

4. First available task picks up message and starts emulator + Chrome

5. SSH Tunnel established between Client and assigned Emulator Task

6. Task updates status to BUSY and stops polling until session ends
