Case Study: Seamless Microservices Upgrade

Case Study

Upgrade to Microservices Completed in 4 Weeks

Open source Micronaut framework enables manufacturing giant to upgrade legacy system to microservice architecture in only 4 weeks

"Micronaut was a key enabler in successfully creating and deploying a web based engineering analysis tool for my company. Its ease of use and great documentation allowed us to produce a tool in an incredibly short period of time. Additionally, the tool has been rock solid since being deployed."

— Client Spokesperson

The Client

A multinational manufacturer of spacecraft, commercial jetliners, fighter jets, rotorcraft, and military cybersecurity systems

The Objective

Replace an obsolete legacy tool with a microservice solution that would deliver maximum performance, scalability, and availability, as well as the flexibility to rapidly deploy changes with minimum down time

The Solution

The company chose Micronaut's built-in Netty-based web server to serve a single-page application (SPA) written in Javascript and CSS. 

Micronaut also hosted the microservices used to perform the business logic. 

Additional Technologies Employed

  • HTML 5, Javascript (ES5), and CSS 3 without a framework to keep the application frontend as fast and lean as possible
  • JSON for communication between the SPA and microservices

Evidence of Success

The development process was smooth, implementation of the solution was seamless, and the application's performance is exceptional.

  • The developer was unfamiliar with Micronaut, but the well-written and thorough documentation and freely available source code on GitHub provided everything he needed to get started and build the solution quickly.
  • The application was developed in only 4 weeks.
  • Initial load of the page is sub-second.
  • Most interactive features of the application are handled in the browser. The remaining interactive features require calls to microservices, which respond sub-second.
  • Updates are deployed with under 10 seconds down time because the Micronaut application starts in under 3 seconds.
  • There were zero unplanned outages during development and implementation.
