Migrate OWASP Nest to Zappa for serverless deployment

[arkid15r]

Description:

We want to migrate the OWASP Nest application to AWS Lambda using Zappa to enable a serverless deployment model. This migration should aim to make the application scalable, stateless, and cloud-native, while keeping existing functionality intact.

High-level goals:

• Deploy the Django + Ninja backend to AWS Lambda using Zappa.
• Serve static and media files via S3 using django-storages.
• Use RDS/Aurora as the backend database, with connection pooling (RDS Proxy).
• Replace long-running tasks and background jobs with Lambda-compatible async tasks or offload to a separate worker (e.g., RQ on ECS/Fargate).
• Update environment and secrets management to use AWS Parameter Store or Secrets Manager.
• Configure logging, monitoring, and CloudWatch integration.
• Create a CI/CD pipeline for automatic deployments with zappa deploy/update.

Acceptance criteria:

1. A fully functional OWASP Nest backend running on AWS Lambda via Zappa.
2. Static/media files served from S3.
3. Background tasks handled in a Lambda-compatible way.
4. Deployment pipeline configured and tested.
5. Documentation updated with deployment instructions.
