Microservices

Microservices is a variant of the service-oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services. In a microservices architecture, services should be fine-grained and the protocols should be lightweight. The benefit of decomposing an application into different smaller services is that it improves modularity and makes the application easier to understand, develop and test.

Microservice architecture, or simply microservices, is a distinctive method of developing software systems that has grown in popularity in recent years.  In fact, even though there isn’t a whole lot out there on what it is and how to do it, for many developers it has become a preferred way of creating enterprise applications.  Thanks to its scalability, this architectural method is considered particularly ideal when you have to enable support for a range of platforms and devices—spanning web, mobile, Internet of Things, and wearables—or simply when you’re not sure what kind of devices you’ll need to support in an increasingly cloudy future.

Microservices Pros and Cons:
Among their advantages for software development, microservices:
    Are easily deployed
    Require less production time
    Can scale quickly
    Can be reused among different projects
    Work well with containers, such as Docker
    Complement cloud activities

However, there are also drawbacks with microservices, such as:
    Potentially too granular
    Latency during heavy use
    Testing can be complex
