Lecture on ECS Service Connect and Inter-Service Communication
Introduction
- Demonstration of how different services within a cluster can communicate.
- Focus on enabling communication between services from different clusters.
- Overview of the solution using ECS Service Connect.
Cluster Setup
- Created a cluster with services: User API and Books API.
- Tasks running successfully within the cluster.
ECS Service Connect
- AWS solution for inter-service communication within ECS clusters.
- Namespace: Key to enabling communication between services.
- If services are within the same namespace, they can communicate.
- Agent: Each container in a service has an agent for managing network communication.
Configuration Process
- **Enable ECS Service Connect: **
- Configure services to use ECS Service Connect.
- Define a namespace for the services.
- **Agent Setup: **
- An agent is launched within each container to maintain network communications.
- **Service Communication: **
- Use HTTP requests to communicate between services.
- Format:
http://service-name.namespace/path.
Practical Implementation
- Cluster and Namespace:
- Example namespace: Bookshop.
- Services created: Users API and Books API.
- **Creating Services: **
- Users API:
- Turn on Service Connect, select client and server.
- Define endpoint:
http://users.bookshop/path, exposed on port 9001.
- Books API:
- Turn on Service Connect, select client and server.
- Define endpoint:
http://books.bookshop/path, exposed on port 9000.
Testing and Verification
- **Endpoints: **
- Users API:
http://users.bookshop:9001
- Books API:
http://books.bookshop:9000
- SSH Verification:
- Future steps to SSH into the services and verify the communication.
Conclusion
- The setup of ECS Service Connect for enabling inter-service communication is effective.
- Agents handle network communication, simplifying the process.
- Future videos will cover testing and verification via SSH.
Stay tuned for the next video on testing inter-service communication.
