Synchronous Messaging Patterns
Synchronous messaging patterns involve real-time communication between components, where a request and response occur in a tightly coupled manner. Two fundamental design patterns in this category are:
Request-Reply Pattern
In the Request-Reply pattern:
- Imagine sending a message to a friend and waiting for their response before continuing the conversation.
- Similarly, a component in a cloud-native application sends a request to another component and patiently waits for a response.
- This synchronous interaction is like having a real-time conversation, ensuring immediate feedback.
- It’s particularly useful in scenarios where quick, real-time responses are crucial, such as in user interfaces or applications requiring instant confirmation.
RPC (Remote Procedure Call) Pattern
Picture RPC as asking a friend to perform a specific action for you, just as if they were right next to you.
- In cloud-native applications, RPC enables a component to execute a function or method on another component as if it were a local call.
- This is frequently used in microservices architectures, allowing services to communicate smoothly.
- It’s like asking another service to perform a specific task, enhancing modularity and code reusability.
Communication Design Patterns for Cloud Native Applications
In cloud-native applications, the architecture is a critical element that determines the success of the solution. Communication design patterns play an important role in shaping the interaction between various components, ensuring smooth integration, and scalability. In this article, we’ll look into the details of communication design patterns for cloud-native applications, exploring different messaging patterns, and supporting technologies.
