Designing Microservice Architecture the right way is quite challenging and difficult. On contrary to Monolith Architecture which gives one solution for all, Microservice Architecture gives a different solution for different problems. If the wrong solution is chosen, then the Microservice Architecture is just a ticking time bomb that is destined to explode. A badly designed
In Microservice Architecture, there are many Microservices often developed by separate teams. These microservices work together to fulfill a business requirement (e.g., customer request) and communicate with each other Synchronously or Asynchronously. Integration testing of a Consumer Microservice is challenging. Usually, TestDouble is used in such scenarios for a faster and cheaper test run. But TestDouble often does not represent the
Every business Application has many configuration parameters for various Infrastructure (e.g., Database, Network, connected Service addresses, credentials, certificate path). Also, in an enterprise environment, the application is usually deployed in various runtimes (Local, Dev, Prod). One way to achieve this is via the Internal Configuration, which is a fatal bad practice. It can lead to severe
The Bulkhead pattern is a type of application design that is tolerant of failure. In a bulkhead architecture, elements of an application are isolated into pools so that if one fails, the others will continue to function. It’s named after the sectioned partitions (bulkheads) of a ship’s hull. If the hull of a ship is
In Microservice Architecture, where the Microservices communicates Synchronously, a Microservice usually calls other services to fulfill business requirements. Call to another service can fail due to transient faults (slow network connection, timeouts, or temporal unavailability). In such cases, retrying calls can solve fix the issue. However, if there is a severe issue (complete failure of
