The advantages of microservices seem to be strong enough to have assured some big enterprise players such as Amazon, Netflix, and eBay to adopt the major methodology. Compared to more monolithic design structures, those microservices offer:

• Improved fault isolation: Larger applications can remain mostly unaffected by the failure of single module implementation.
• Ease of understanding: With added simplicity, developers can always have a better understanding of the functionality of a service.
• Eliminate each vendor or technology lock-in: Microservices provide the flexibility in order to try out a new technology stack on an individual service as needed. There won’t be as many dependency concerns and each time rolling back changes becomes much easier. With less code in play, there is always more flexibility.
• Smaller and faster deployments: Smaller codebases and scope is equal to quicker deployments, which also allow you to start to explore the benefits of the Continuous Deployment process.
• Scalability: Since your services are separated, even you can more easily scale the most needed ones at the appropriate times, which is opposed to the whole application. When done correctly, this can impact each cost savings.
