Microservices And Java

Microservices holds a special place in the Java world. Java, considered an ideal platform to build mobile device-based services and web client-based services, calls for a need to come across a standardized mechanism. A novel style of architecture – Microservices talks about teaming up various systems, each having its own small, granular and independent service. Building software systems with this style have got increasingly popular and are spreading its advantages all over. With different enablers like Cloud, DevOps and Continuous Delivery supporting it, Microservices has been widely accepted by leading giants as a part of their organizational technology. Microservices is considered an architecture that breaks down a task into small, meaningful, definitive and deployable individual processes. These processes may be independent of each other or maybe talking to each other. Finally, what counts is the destination goal that is set up as a cumulative result of these disparate small services.

As in any kind of technology, be it Java Application Development on any other, it is vital to study the proposed environment and requirements before proceeding for implementation. For Microservices architecture too, this applies to the core. Before you proceed with a decision to choose this wonderful architecture, you need to be sure of certain parameters and ascertain its usage. It cannot be implemented in all projects.

Scenarios Where Microservices Can Be Chosen

Java Microservices

  • Separation Of Business Logic

A case where business logic can easily be separated and is well defined is ideal, since, in Microservices, the entire process is divided into small molecular processes. Once it is split into individual processes, it becomes a simplistic task for the developers to work in parallel without conflicting interests as against traditional patterns.

  • Handling Legacy System

In places where you have large and complex legacy systems, Microservices can play a very important and beneficial role since such systems are difficult to decode. You can extensively use the features of Microservices to handle such legacy data.

  • Easily Dividable Team

Based on the variety of processes involved in the entire project, Microservices architecture allows the flexibility to divide the team into separate sections, based on the skills which are necessary to achieve respective services.

  • Scaling Up / Down

Because the entire setup application is divided into smaller, individually deployable services, only the necessary component has to be either scaled up or scaled-down. If we take it in simple terms if there is an application of 100 services out of which 10 are hit ones and in great demand, with the usage of Microservices, we can scale up only those components which are in high demand and ignore the others. If it weren’t Microservices, there would have been the implementation of a single deployable unit to manage the entire clustered load.

Benefits Of Microservices That Surpasses Its Peers

  • Enhanced Simplicity

As compared to SOAP (Simple Object Access Protocol), today REST (Representational State Transfer) is ruling since its simplistic and lightweight. REST has great support for the simple JSON (JavaScript Object Notation), which is preferred by web developers.

  • Service To Function Mapping

Irrespective of the size that SOA talked of Microservices has no size limit and focuses primarily on each service performing a single function. Owing to this concept, Microservices stars individually

  • Novel Container Technology

Everyone’s favorite today – the open-source project Docker, has been a prime component in increasing the popularity of Microservices. Docker has been perfectly suited to deploy and manage Microservices with the least of operation overheads.

  • Cloud-Based Technology

The auto-scaling functionality of cloud-based technology has proven its existence and importance while implementing Microservices. Originally, with SOAP technology, services were shared by applications resulting in timeouts and slowdowns. This has now been overcome by the cloud infrastructure.

  • Support Overhead

Because of the involvement of varied services, support to each one of them becomes a must, thereby increasing the complexity.

  • Inter-Service Communication

Communication between services is needed since one task is split into multiple services and this has to be handled with care so that each of the processes works and aims towards the common objective of the entire application.

  • Need For Experienced Developers

Since the Microservices architecture is complex in nature, proficiency and expertise is a very prime need for the Java developers. Getting a team with mature and skilled professionals is surely a tough task.
