MicroServices — An Introduction

In the technological environment, a lot of people are describing the term “Micro services” because microservices are about to take over the software development. Every technical employee should be aware of microservices.

What are Microservices?

Microservices architecture is a Service Oriented Architecture. This architectural style is providing a way to develop software, web or mobile-based applications and it is a loosely coupled architecture that means developers can create, modify and update their modules in separate processes and facilitates independent deploy of modules. Each service is written in a different programming platform and these microservices can communicate through different APIs.

Features:

Easy Deploy

Microservice architecture is built with multiple modules such that the modules can be updated, modified or deleted independently without affecting other service modules. This ensures reusability and in-dependency.

Modularity:

Microservice architecture is built with multiple modules such that the modules can be updated, modified or deleted independently without affecting other service modules. This ensures reusability and in-dependency.

Distributed Broadcast:

On the rule of distribution, the developing software tools are distributed to others to solve the data problems. Microservices offers decentralized data management. Each microservices have unique databases to modify, operate, deploy, and manage.

Low Cost:

The scalability cost is low. Because every service uses separate modules hence it is easy to expand the data storage.

Heterogeneous:

Easy to implement different kinds of technologies for variety of features in services.

Fault tolerance:

In micro services environment different applications and services communicate with each other. If a service failure happens, the client can allocate another service to do their failed task.

Advantages of micro services:

  • Easy to scale and integrate with third-party services
  • No long-term commitment to technology stack
  • Better Fault Isolation. If any system fails other systems can work.
  • If any error occurs in any system. It is easy to manage and deploy the single system, update the component easily.
  • The developer has to include the new ideas in separate modules.
  • Flexibility to implement a new technology.

Disadvantages of microservices:

  • It requires large memory space
  • It became a distributed environment testing is complicated
  • Information barrier is one of the fault due to increasing the number of services.
  • Integration and management are questionable as the product is distributive in nature.
  • Need additional attention from developers for updates and maintenance.

Conclusion

To summarize, Microservices is a variation of the traditional software development process that is split as a set of fine grained, loosely coupled services that supports easy deployment with less faults and comparatively at a lower cost, a win-win for all.
