2 Inter-Process Communication (IPC)
Note
This note is a placeholder for Inter-Process Communication concepts. Content to be added based on system design patterns and AWS service integration.
Overview
Inter-Process Communication (IPC) refers to the mechanisms that allow processes to communicate and synchronize their actions when executing concurrently.
Common IPC Mechanisms
Message Passing
- Processes communicate by sending messages to each other
- Can be synchronous or asynchronous
- Examples: Message queues, pub/sub systems
Shared Memory
- Multiple processes access the same memory space
- Faster than message passing but requires synchronization
- Common in high-performance computing
Remote Procedure Calls (RPC)
- Allows a program to execute procedures on remote systems
- Abstracts network communication
- Examples: gRPC, REST APIs
AWS Services for IPC
- Amazon SQS - Message queuing service
- Amazon SNS - Pub/sub messaging service
- Amazon EventBridge - Event bus for application integration
- AWS Step Functions - Workflow orchestration
- Amazon Kinesis - Real-time data streaming
