Good Maintenance from a development perspective: As each service has an independent role and is comparatively smaller than a single monolithic application, so maintaining or fixing an issue in a microservices is much easier than an entire monolithic application. A superior Microservices Company always delivers great service and makes sure that maintenance is excellent and convenient.
Eliminates the fear of a single point of failure: The entire single application is divided into small and independent microservices so if one service is down it does not affect other parts of the application which are independent of the service that is down. But in a monolithic application if there is an issue in one part then there is a possibility that the entire application crashes.
Releasing a feature is less of a headache: In a monolithic application if we want to release a new feature we have to somewhat run an integration test on the entire application again to check whether or not the new feature has introduced an issue in some other part of the code. But in a microservice architecture, this is not the case. We just need to perform an integration test on the service in which a new feature is added or at max on the services that are somewhat interrelated to that service.
Highly and Easily Testable: Each service is independent and comparatively smaller than a monolithic application so performing unit or integration test is less time consuming and much easier.
Multiple Language Application can be easily developed: In a microservice architecture each service can have a different technology stack. So having this benefit would lead to many improvements like we can eliminate commitment to a particular technology stack for a long time. Many times it is seen that one technology or language is not a good fit for a particular functionality but another technology is a good fit for that functionality so we can implement that functionality in a different microservice with the technology that is a good fit for it.
Improve Fault Isolation: In a microservice architecture finding and fixing a fault is much easier than a monolithic application due to the smaller size of each service as compared to an entire monolithic application.
