Microservice is a collection of small, independent, loosely coupled, and autonomous services. Here each service is self-contained and implements a single business capability. Its services can be deployed independently and can be updated on the existing service without re-building and re-deploying the entire application. The services in this architecture are responsible for persisting their data or external state. This approach is very different from the traditional model where there is a separate layer that handles the persistence.   Here services communicate with each other by using the well-defined API in the model. Here internal implementation details are hidden from the external users and they have displayed the necessary information required by them. Most importantly services are not required to share the same technologies such as technology stack, libraries, or framework. In this architecture, each component is responsible for placing the services on the nodes, identifying the failures, rebalancing the services across the platform. Along with this it also provides the facility of API gateways which help in forwarding the call to the appropriate services on the backend. With the help of this facility, it decouples the clients from the services. The services can be versioned and refactored without updating all clients. Further thus platform also supports the messaging protocols. Further, this architecture also supports authentication, logging, SSL termination, and load balancing.

Benefits of micro-service architecture

• Microservices are deployed independently which supports agility.
• The services can be versioned and refactored without updating all clients.
• It supports the small and dedicated teams to process the services that support testing, updating, and maintaining the functions in well-versed form.
• It has a small code base that provides the facility of updating the services more effortlessly.
• It also provides the facility to its uses to select technology from various technologies provided in the platform or can use the combination of various technologies as per requirement.
• Further, it also provides the facility of fault isolation as a single bug will not affect the entire application.
• Its services can be scaled independently without scaling the subsystems. 
• It provides an easier method of performing the schema update.  
• This architecture is highly maintainable and is loosely coupled. It is independently deployable.

 

DevOPs and its application in Microservices

DevOps are a set of practices that combines software development and IT practices under one umbrella. The main objective of DevOps is to reduce the software development life cycle and provide continuous and high-quality service to its users. DevOps helps in breaking the wall between the operations and development for creating the rapid and automated process that helps in faster development of the applications. Here both the operation engineers and development engineers are jointly involved in the software development. The microservice architecture builds the complex architecture from its microservices and by using the DevOps the development of these services can be done in a better way. It helps in breaking down the complex processes in a smaller form and then performing the task of development. It helps in increasing the productivity and reliability of the services provided through this architecture. It further supports in creating the services on various servers in an easier way. Most importantly it supports the round-to-clock mode of service availability to its users. It provides improved agility that allows for quick results, rapid reiteration, and quicker time for deployment. As these services are loosely coupled the management of the entire application is easier. The management of the service is easier in comparison to other approaches. By implementing the DevOps in the microservices the application deployment and development becomes less time-consuming. It also supports fault tolerance and bug removal from the application. Here the deployment, testing, collaboration, and maintenance of the application can be done more easily. Along with this it also provides the facility of API gateways which help in forwarding the call to the appropriate services on the backend. With the help of this facility, it decouples the clients from the services. The services can be versioned and refactored without updating all clients.
