Quite often the tooling is a forgotten area during the beginning of development. This chapter overlooks the tooling that can help build and maintain event-driven microservices. Useful checklist! This topic includes:

• Org rules
• Documentation, tagging
• Quotas
• Schema registry
• Offset management
• ACL
• State management and app reset
• Consumer offset lag monitoring
• Container Management Controls
• Cluster Creation and Management
• Dependency Tracking

All of these is disclosed in the Chapter 14 of the book:

How to integrate event-driven microservices with request-response APIs?

There are two types of external events:

• Autonomously Generated Events (analytical events)
• Reactively Generated Events (events from request-reply)

There are two approaches of processing and serving requests using stateful services:

• using internal state stores (with silly or with smart routing)
• using external state stores (with regular or with composite microservice)

Ways of handling requests within an event-driven workflow:

• Handling requests directly
• Turning requests into events (big latency)
• Processing events for user interfaces (a mix of two ways)

Approaches for request-response applications, their pros and cons:
