Break It Down: The Advantages of Microservices

By Team Srijan Aug 29, 2018

Enterprises using monolithic systems to support large applications find it increasingly difficult to respond to evolving business priorities and rising customer expectations. Every functionality is built together as one single block, and it’s almost impossible to change or update a portion of it, without overhauling the complete monolith. And that is why enterprises IT teams are rapidly exploring the advantages of microservices.

Legacy systems are inflexible, hard to scale, and unable to keep pace with emerging technologies. One large code base makes it difficult to update or modify the application for a specific feature request. This leads to a greater learning curve, increases deployment cycle and project delivery timeline, slows down time-to-market and complicates delivery of new capabilities.

If your enterprise system are based on a monolithic architecture, here’s what you need to consider:

  • How to achieve faster go-to-market with new application, and new updates on existing applications, while minimizing downtime
  • How to optimize scalable application development, even as you deploy multiple teams across diverse platforms

The answer is microservice architecture. Let’s take a closer look.

What is Microservice Architecture?

The microservice architecture essentially breaks down complex applications into its component functionalities, and creates each of them as independent, self-contained services.

What is Microservice Architecture?

With microservices, an application is built as a suite of small services, each running in its own process and communicating with lightweight mechanisms often an HTTP resource - API. Each of these microservices focus on completing one task only (representing a small business capability) and do that task really well.

These microservices can be developed in any programming language and have a bounded context, which means that they don’t need to know anything about underlying implementation or architecture of other microservices.

Advantages of Microservices Over a Monolithic Architecture

The microservice architecture has several advantages over a monolithic architecture, specifically focused on the code base, delivery and deployment.


Monolithic Architecture

Microservice Architecture


A single code base for the entire application

Each microservice has its own code base


Often confusing and hard to maintain

Much better readability and much easier to maintain


Complex deployments with maintenance windows and scheduled downtimes

Simple deployment as each microservice can be deployed individually, with minimal or zero downtime


Entire application is developed only in one programming language

Each microservice application can be developed in a different programming language


Requires you to scale the entire application even though bottlenecks are localized

Enables you to scale bottle-necked services without scaling the entire application.


Tightly coupled with interdependent components that cannot be deployed without following a defined procedure

Loosely coupled, demands self-sufficient services and avoid hard-coded references to other services


Applications are developed, and updates are made when scheduled (quarterly or annually)

Microservices is delivered continuously- is deal for teams that have apps with constantly changing needs

The Business Benefits

Microservice architecture is helping enterprises deliver richer experiences for customers as well as employees.

  • Responsive - Companies that adopt a microservice architecture can continuously deliver capabilities according to the customer’s changing needs.
  • Continuous Delivery- Microservices built on the principles of Agile and DevOps help the software teams run parallel projects while iterating quickly on discrete capabilities.
  • Scalability and Reliability - A successful microservice architecture prevents any system failure. Its repeatable automation, scaling application, and designing pattern features keep the system running.

While microservices become an increasingly popular service architecture, it may not necessarily be the best fit for your project. The monolithic architecture still works better for simple, lightweight applications. However, enterprise digital transformations typically demand complex, evolving applications and for those, microservice architecture is undoubtedly a better choice.
