Traditional monolithic architectures are built around the concept of large applications that are self-contained, independent, and incorporate myriad capabilities. As developers move to microservice-centric designs, components are broken into independent services to be developed, deployed, and maintained separately. Faster performance.

In Domain-Driven Design, a large system is decomposed into bounded contexts , which become natural boundaries in code as microservices and as teams in the organisation. The Bounded Context Design Canvas I designed this canvas based on the typical flow of strategic DDD workshops I run publicly and privately.

If used correctly, this pattern can improve performance and help maintain consistency between the cache and the underlying data store. This post is part of a Design Patterns series. It may be beneficial to have the application prepopulate the cache as part of the startup process. Reading Data. Consistency.

Modern software usually involves running tasks that invoke services. If the service is subjected to intermittent heavy loads, it can cause performance or reliability issues. The service retrieves the messages from the queue and processes them. The queue acts as a buffer , storing the message until it is retrieved by the service.

The need for systems to be resilient is still increasing, and chaos engineering tools and techniques are developing as a key way to validate that resilience is working as designed.

Building on the Queue-Based Load Leveling Pattern , the Competing Consumer Pattern enables a system to process multiple messages concurrently to optimize throughput, to improve scalability and availability, and to balance the workload. Systems that use the Competing Consumer Pattern should ensure that message processing is idempotent.
