For better understanding and to make a right decision between choosing from these two, listed below is a brief definition and description:
Web services are basically a representation of a website application’s functional module and can be defined as the particular case of SOA that is Service Oriented Architecture. It works on the core mechanism of exposing the main functionality of the application to the other application, without owing to a user interface in between. It enables and defines mechanism of API interaction as its main interaction with the main code by further using the universal and international formats of data representation such as the standard HTTP protocol, along with XML, JSON etc. However, it should also be noted and considered that the web services are not attached and linked to the development languages or any of the user device software and application platforms. With this factor, one can easily and effortlessly combine the several types of web services in to one, even if each of them is written in a solo language and with a single OS.
A micro service can be defined as an independent deployed web service which is modelled around a specific business domain. Micro services basically works on the core principle of breaking large software application programs into loosely attached and coupled modules where in each of the individual service runs on its unique and single process to communicate with the use of API’s. They are usually developed by taking the aid of messaging or the event related and driven API’s, or else by using non HTTP which are backed with RPC mechanisms. Micro services are basically designed with an aim to cope up with the constant failures and regular breakdowns of large web applications and solutions. It is when multiple and coupled unique web services are working and communicating together , one of the service may fail but it would not affect the overall working and functioning of the large applications by remaining unaffected to the failure of a single web module.
Which Application to choose and why?
By considering the advantages that both the services offer, we can say that micro services and web services both are superior web app solutions to the web applications with monolithic web architecture. It is because they both represent separate and individual services which are interconnected with network protocol web components that work independently and uniquely from one another.
Let’s find out which of the services would be more befitting to your business needs and organization as per the use cases:
It is known that each of these services is attached to a separate & individual data source (DBMS). Therefore, the continuous use of web apps multiple and varied features can result in a requirement to execute dozens of online users requests. As a consequence to this, the system will become overloaded and will further result the app to crumble in a pressure of numerous active users. Here, at such situations, web services are found to be helpful in finding and maintain a balance between the scaling accessibility and the overall level of fail and error safety.
Creating an app for business requires the function to be error and extensive fail safe. Whereas, there is also a need to customize the monolithic architecture software, for if you decide to decentralize the whole system. At such times, you may face a difficulty to separate the micro services that would not work independently and you will have to rewrite and develop everything from the scratch. This is why to avoid such situations, it would always be better to provide such web components in the form of complex and steady web solution that is a web service solution.
