Architecture Documentation
- Leverages AWS Lambda and API Gateway
- Removes Spring Boot Resource Server. Replaced by API Gateway
- Removes need for proxy web server
- Remove heavyweight spring boot server
- No need to pay for Lightsail or EC2 with memory sufficient to host Spring Boot resource server.
- Reduced cost
- DDoS protection
- API Gateway defines endpoints and trigger AWS Lambda functions
- AWS Lambda functions establish connections to database running on Lightsail Instance and handle CRUD operations. Return response to the client
- Leverages AWS Lightsail, Java with Spring Boot, NGNIX as a proxy server, and PostgreSQL
- Can host multiple resource servers for multiple applications
- Can define and host multiple backend applications and services on the same instance
- Serves as a great playground to learn about managing backend services with server-based/traditional architecture
- Need to pay for a Lightsail or EC2 instance large enough to host spring boot application
- Need to manage servers. High maintenance.
- Manually managing security against potential attacks including DDoS
- Resource Server defines endpoints
- NGINX Webserver listens on open port. Directs HTTPS requests to different Spring Boot applications running on different ports, based on the domain in the endpoint
- Resource server establishes connection to database running on same Lightsail Instance, handles CRUD operations and returns response to the client
