Microservices Why, When and How

Microservices

Microservices is a hot topic in the IT industry and software development circles today due to many reasons. In the past, the industry used a monolithic development approach. They used a simple application development method for a single application. But, once the application becomes successful, there comes the need to scale up the application. New features can come in, new technologies should be used, and new concepts and database connectivity should be implemented. In this situation, the application becomes more and more complex. The number of developers and teams might increase due to the requirements for the application, and the development becomes complex. As this is a single application concept, different technologies cannot be used.

Main reasons why you should move to Microservices?

• Microservices introduces the concept of modularity.
• These multiple modular components are loosely coupled.
• Individual services can use different technology concepts.
• Individual services can have different database connections.
• Multiple development teams can collaborate to implement these components separately.
• Collaboration becomes easy.
• It is easy to plug in a new service or remove an already implemented service.
• These services can be individually deployed into a cloud environment or data centers.
• Improved scalability where it allows you to scale up and down the individual services. And these scaling decisions can be taken at a more granular level.
• The individual components provide more fault isolation as this provides easier debugging and maintenance.
• Microservice concept goes nicely with DevOps as well as microservices allows rapid application changes.

The above mentioned are a few of the reasons that make the software industry move into microservices.

When to use microservices?

The following lists down when you should think of using the microservices architecture.

• The software industry needed a way to implement a component-based architecture when individual components can be plugged in or out when needed without much hassle. Microservices architecture provides the individuality of components where components can perform independently with their own technology and database.
• Low cost and time are also other reasons to be moved into the microservices architecture. Businesses primarily focus on low cost, low budget software where microservices can implement components without much hassle, and rapid development and release can be done.
• The product-based concept of the software is another reason to use microservices architecture. Even though the monolithic concept can also be used for product-based development, microservices separate the developer and user’s specific service by providing an entire lifetime product concept.
• If you want decentralized governance, then microservices are the way to go. The monolithic application concept can only use a single technology platform. However, microservices allow different languages or database platforms on the different microservices components.
• Microservices allow the management of different databases for different services. If the requirement is to use particular database technology for one business purpose and another requires a different database technology, you should be selecting microservices.
• When you need hassle-free CI/CD (Continuous Integration/ Continuous Delivery), you can use microservices where it allows the deployment of individual components.

How to use microservices?

When using microservices, it is crucial and a best practice to use a relevant platform that helps easy development, deployment, integration, DevOps capabilities, and monitoring.

CODEOBE is a platform that eases microservices development, micro integration development, and DevOps tasks with in-built monitoring (https://www.codeobe.cloud/). You can quickly build, deploy, and manage your integrations.
