What is Microservices Architecture in Cloud Computing

Due to the prevalence of mobile computing in recent years, application developers have been forced to deliver activities fast and make modifications to programmes without total redeployment. This has resulted in a new development paradigm known as “microservices.”

Microservices, also known as microservices architecture, is a method of developing big applications using modular components or services. Each module supports a single activity or business purpose and communicates with other sets of services via a simple, well-defined interface, such as an application programming interface (API).

Microservices are small, self-contained components that execute specific tasks within an application and communicate with one another via APIs. In this article we will discuss about the benefits of microservices architecture in application development.

What is microservices architecture used for?

Microservices are typically used to accelerate application development. Microservices architectures developed with Java are prevalent, particularly those implemented with Spring Boot. Microservices and service-oriented architecture are also frequently contrasted. Both share the same goal, which is to break down monolithic applications into smaller components, but their methodologies differ.

Examples of Microservices Architecture in Cloud Computing

Here are some examples of microservices architecture: 

• Website relocation

A sophisticated monolithic platform-hosted website can be moved to a cloud-based and container-based microservices platform.

• Media content

Images and video assets can be stored in a scalable object storage system and provided directly to web or mobile using microservices architecture.

• Transactions and bills

Payment processing and ordering can be split as discrete units of service, allowing payments to be accepted even if invoicing is not functional.

• Processing of data

A microservices platform can supplement existing modular data processing services with cloud support.

Benefits of using cloud microservices

Microservices are decentralised and run on separate servers, yet they nevertheless collaborate to execute an application. Each microservice should ideally perform a single function, allowing for simple routing between services via API communication.

Here are a few more advantages: 

• Continuous integration/continuous delivery (CI/CD) allows you to update code at any moment. With CI/CD, you can disburse little pieces of code rather than large packets.
• The user is unaware of changes that occur on the back end.
• Parallel development teams are possible. Small teams can move more quickly than huge teams.
• The components of the application service are segregated. If one fails, the others continue to work, allowing for graceful degradation.
• The only time a human must respond to an alert is when there is a system bug.
• If a back-end function fails (for example, a database request), it returns something helpful. Microservices are designed to manage faults in a logical manner.
• Because microservices architecture components are granular, it is easier to improve and maintain code.
• Developers and groups can work together to ensure that APIs connecting services are widely available.
• Microservices expand modular code development best practices.

Challenges of a microservices architecture

However, there are several disadvantages of using microservices, such as: 

• perhaps excessive granularity
• extra effort in planning for inter-service communication;
• complicated testing,
• lag when under severe load.

How are Microservices Scaled?

Businesses can use microservice architectures to divide programs into multiple areas managed by different personnel. It is essential when creating large-scale applications.

One of the primary reasons organizations select the public cloud to deploy microservices applications is that on-premise infrastructure is better suited for outdated monolithic programs, albeit this isn’t always the case.

Both of these concerns have been addressed by a new generation of technology companies. The division of roles promotes independent work on individual services, which has no influence on other developers working on the same application.

Conclusion

In the future, microservice architecture may or may not become the favored development style. It is indisputable, however, that it is a potent notion with substantial implications for enterprise application design and deployment that can benefit.
