Sometimes, you need an application that may be required at more than one stage of a complete process. You use it with all its components interconnected. If you make a change in one component, then the whole application gets affected. That application is called monolithic application. It is an expensive proposition as it needs to be maintained exclusively. Monolithic applications are viewed as inflexible systems.
There is one more application that is small, independent & re-usable. Also, it can be modified and deployed independently in a process. It puts individual functionalities into separate services. It does not affect the whole process. It is flexible. Each service has its own process and communicates with the help of an HTTP resource web service. It is called ‘microservices’. It saves a lot of investment. It can be linked with other such units to form a larger system.
The microservices way of developing and managing software applications is more suitable to changing business requirements, and that is why the organizations are going towards it. The main reasons for the popularity are as follows:
The components of a microservice architecture are called its main defining characteristics.
Microservice architecture working is based on its principles which can be applied across software applications, regardless of technology or platform. The development team is given the full responsibility after the software has been delivered.
The microservices use services that are out-of-process components. They communicate with the software with the help of elements like web services or a remote procedure call.
Service-oriented architecture is based on services which perform various functions like displaying system status, creating users and updating the user’s data.
It allows software developers to build, call and expose services and create the services to provide a solution. Just like in microservices, Service-oriented architecture services are all independent, loosely-coupled services. The main difference between service-oriented architecture and microservice architecture are described as follows:
Many prominent organizations have been opting for microservice architecture like Netflix, eBay, Amazon, Twitter, PayPal.
Microservices are natural choice as they are more adaptable to the changing business scenario. However, their managing teams must have clear understanding of putting together so many diverse services to fulfill a single objective.
