![]() This pattern enables the application to generate various views, but its layers of abstraction increase complexity. ![]() The model contains the application's data and main functionality the view displays data and interacts with the user and the controller handles user input and acts as the mediator between the model and the view. The model-view-controller (MVC) pattern divides an application into three components. Because each application is small, it's easier to update them when needed, but the complexity means you need greater architectural expertise to make everything work correctly. The microservices pattern combines design patterns to create multiple services that work interdependently to create a larger application. The layered pattern makes it easy to write applications quickly, but a disadvantage is that it can be hard to split up the layers later. The layered pattern is good for e-commerce, desktop, and other applications that include groups of subtasks that execute in a specific order. It's very flexible but demands a highly efficient and reliable network infrastructure to minimize latency. It sends a continuous stream of messages to a database, web server, log, or another target. The event sourcing pattern is good for applications that use real-time data. One advantage is that you can read data from the responder without affecting the data in the controller, but if the controller fails, you may lose data and need to restart the application. The controller-responder pattern divides the architecture into two components: The controller handles the data and distributes workloads, and the responder replicates data from the controller and generates results. It separates read and write activities to provide greater stability, scalability, and performance, but it requires more database technologies and therefore may increase costs. The command query responsibility segregation (CQRS) pattern handles the situation where database queries happen more often than the data changes. One advantage of this pattern is that data and network peripherals are centrally managed, however, the server is expensive. Examples include banking, file sharing, email, and the World Wide Web. The client-server pattern is a peer-to-peer architecture that is comprised of a client, which requests a service, and a server, which provides the the service. While it helps make systems more fault tolerant to prevent accidents, it also requires sophisticated testing and using an infrastructure-management technology like service mesh. The circuit breaker pattern minimizes the effects of a hazard by rerouting traffic to another service. If one piques your interest, click the link to learn more.
