What is pub-sub architecture and how can I design it?
Pub-sub architecture is a messaging pattern where publishers send messages without knowing who will read them, while subscribers receive messages without knowing who sent them. To design it, you need to define your message types, choose a messaging broker, and establish how publishers and subscribers will communicate.
What are some common use cases for pub-sub architecture?
Common use cases include real-time data processing, event-driven systems, and microservices communication. It's great for applications that require decoupled components.
What messaging brokers do you recommend for implementing pub-sub?
Popular messaging brokers include Apache Kafka, RabbitMQ, and Google Cloud Pub/Sub. Each has its strengths depending on your specific needs.
How do I ensure message delivery in a pub-sub system?
To ensure message delivery, you can implement acknowledgment mechanisms, use durable subscriptions, and consider message persistence in your broker.
