Microservices - What and Why

The rapid adoption of cloud platforms has made both Microservices and Serverless architectures integral to digital transformation. While we have already covered
why going serverless may prove to be better for your busines and a few examples and use-case of the same in our previous blogs, here we are going to speak more on Microservices, what it is, and its benefits.

With the wide adoption of cloud computing, enterprises have migrated or refactored their existing monolithic-based applications into the microservices architecture. On the other hand, serverless computing is also gaining popularity and more adoption in different fields since the launch of AWS Lambda. Both the architectures have their pros and cons and the decision to adopt a design pattern depends on the team capability and project requirements besides factors such as scalability, reliability, and cost.

What is serverless?

Managing architecture seems challenging for a growing organization and software teams often find themselves occupied with development. Serverless plays a vital role in such scenarios; it is a way for companies to build and run applications without managing the infrastructure. It removes architecture responsibilities including provisioning, scaling, and maintenance. The main reasons behind adopting serverless  include reduced costs, scalability, developer productivity,

  • No server management is necessary
  • Only charged for the server space they use, reducing cost
  • Serverless architectures are inherently scalable
  • Quick deployments and updates are possible
  • Code can run closer to the end user, decreasing latency

What is Microservices?

Microservices architecture decouples a monolithic-based application into smaller services and each service can then be deployed separately either on a virtual machine or in a container where the resources can be scaled on-demand. 

  • Highly maintainable and testable
  • Loosely coupled
  • Independently deployable
  • Organized around business capabilities
  • Owned by a small team

Market Size

The cloud microservices market extrapolated to grow from $683.2 million in 2018 to reach $1,880.0 million by 2023 at a Compound Annual Growth Rate (CAGR) of 22.4%.


  • Digital Transformation
  • The proliferation of the microservices architecture
  • Customer-oriented business


  • Increasing adoption of cloud-based applications
  • The emergence of IoT applications

How it benefit your organization

The microservices architecture helps enterprises rapidly build and deploy business applications. It provides greater flexibility in developing applications as compared to monolithic architecture.

In addition to this, microservices are helping businesses in reducing the complexity of the software development process. Hence, businesses are adopting the cloud microservices approach, which is essential in developing advanced business applications.

In today’s business environment, with the rapid advancements in technologies, there is an increase in the use of digital solutions, connected devices, and IT systems. Microservices and Serverless, both have paved the way for the growth of digital transformation empowering organizations to implement new applications to engage customers in innovative and captivating ways.
