MicroService Architecture Patterns
Why
Microservice architecture patterns are used to improve the scalability, resilience, maintainability, and agility of an application. They can help to improve the customer experience, reduce costs, and increase innovation.
Microservice architecture patterns:
Aggregator:
An aggregator is a microservice that collects data from other microservices and provides a consolidated view of the data.
API gateway:
An API gateway is a microservice that provides a single point of entry for all of the other microservices in an application.
CQRS:
CQRS stands for Command Query Responsibility Segregation. It is a design pattern that separates the commands that modify data from the queries that read data.
Event sourcing:
Event sourcing is a design pattern that records all changes to data as events.
Saga:
A saga is a long-running transaction that spans multiple microservices.
The specific patterns that are used in an application will depend on the specific requirements of the application.
Placing your bet
If you are considering using microservice architecture, it is important to weigh the benefits and drawbacks carefully. Microservice architecture can be a good choice for applications that need to be scalable, resilient, maintainable, and agile. However, it is also more complex and expensive than monolithic architecture.
Here are some additional things to keep in mind when using microservice architecture:
Communication and coordination:
Microservices need to be able to communicate and coordinate with each other in order to function properly. This can be a challenge, as it requires careful planning and design.
Security:
Each microservice has its own security perimeter, which can make it more difficult to secure the overall application.
Monitoring and observability:
Microservice architecture can make it more difficult to monitor and observe the application. This is because there are more components to monitor, and they may not be centrally located.
Overall, microservice architecture is a powerful architectural pattern that can offer a number of benefits. However, it is also a complex pattern that requires careful planning and execution. If you are considering using microservice architecture, it is important to weigh the benefits and drawbacks carefully.
