5 Real World Use Cases of Microservices

Manju Naglapur | 4 min read

Today, nearly 63% of enterprises worldwide have adopted microservices architecture. It has been widely embraced because of the modular approach (instead of monolithic) for software development that enables the rapid, frequent, and reliable delivery of large and complex applications.

Organizations have been able to deploy different teams to work in a decoupled manner on various services independently to create an application that works as a collection of services. Now applications can use an evolved technology stack to create a highly maintainable, testable, and scalable application organized around business capabilities.

In this article, we will take a look at some of the real world use cases of microservices and related case studies (wherever available) to give you a more detailed understanding.

Modernizing and Refactoring Legacy Applications

To be future-ready and agile with the evolving technologies, it is essential for businesses to move from legacy to modern platforms. To ensure a strong and modern IT infrastructure is built, refactoring it with microservices that allows you to deploy full-stack development technologies.

Here is an interesting application modernization case study. We helped one of the leading US financial services firms to modernize their complex application built on monolithic architecture into microservices. This has lead to 4x improvements in application performance with horizontal scalability.

Big Data Applications

Microservices, coupled with Event-Driven Architecture (EDA), is a natural fit for complex applications and cloud environments in many cases. It provides the scalability and extensibility to the required application because of it’s loosely coupled architecture.

In its own application deployment, Amazon simplified its pipeline, uncovered problem areas, and rebuilt a robust application framework while introducing a solid open source system to cater to the huge volume of data processing. The service-oriented microservices architecture optimally supported every function across the globe.

Growing traffic was overwhelming for eBay; however, it was becoming difficult for the systems to handle the complexities of growth. To cater to 75 billion database calls in a day, eBay decided to divide the application, database, and even search engines by adopting the microservices architecture. Since the technology was first introduced, constant and timely updates have kept the company website stable while boosting its time-to-market rate.

New call-to-action

Real-time Data Processing 

The publish-subscribe messaging pattern used in microservices architecture enables a seamless asynchronous communication to process and analyze data in real-time for streaming platforms to generate intelligent outputs.

It takes more than 500 microservices and API’s to deliver a product as refined as Netflix, an over-the-top content platform and production company. And as an early adopter making it an engrossing case study that focuses on the many benefits of microservices.

Organizations that capture high-volume unstructured data such as social media networks like Twitter need to be scalable and at the same time flexible. Microservices makes it seamless to identify roadblocks and enable faster deployments. Twitter moved from the traditional web application to the microservices architecture using Scala and Java.

Multi-Group Developments 

To meet frequent release timelines, multiple developers working on the same piece of an application’s feature is how the software development space is building up. To cut down scenarios of the code succumbing on the ‘merge day’, microservices architectures enable applications to be split up into independent services, to be able to be managed and plugged in together by individual groups.

The DevOps Model

DevOps and microservices work flawlessly when applied together. Microservices improve the productivity of the DevOps team by embracing a common toolset that can be used for both development and operations. This enables a common terminology and processes for project requirements, task dependencies, and challenges. Now Developers and  Ops people can work jointly on a problem and successfully fix a build configuration or build script.

Coca-Cola made an early decision to adopt microservices. This structure is divided into a single app via which they are able to address any speed or agility related issue. Added to this, they created Anytime Platform – a set of reusable modules accessible by every business entity in the group.

Other than the above, applications that are used across multiple channels such as notification, login service, travel, and hospitality booking services (such as Airbnb) and related ones – are better to be built on microservices.

These successful microservices architecture use cases make it an unavoidable and integral part of your business technology. There could be different reasons that lead to it, but the results are bound to be the same – efficiency, growth, innovation, and advancement.
