This design pattern is used to stop the process of request and response if the service is not working
In this design pattern, when the number of failures crosses a threshold limit, the circuit breaker trips for a particular period, and all the attempts to invoke that service will fall in that particular period. Once that period is done, the circuit breaker will allow a limited number of requests to pass through & if success resume back to normal operation else it will show failure again and the time will begin
Offers no exhaustion of network resources and user experience is kept on a good note

2. Decomposition Design Pattern

Let us take a look at this design pattern:

It talks about breaking an application into small autonomous units and is done logically
The application is broken down based on three thing’s i.e. Sub-domains of application, Business capability, and Strangler or Vine pattern

2.1 Strangler Design Pattern

Let us take a look at this design pattern.

It is a design pattern that offers a way to break the monolithic application into smaller autonomous units
It is a pattern to incrementally transform the monolithic application into microservices by replacing a particular functionality with a new service. Once the new functionality is ready, the old component is strangled, and the new service is put into the use and old component is decommissioned altogether
This pattern helps to achieve the highest code quality, follow TDD for business logic, and Sign up
