Journey to Microservices

Several factors are driving organizations to redesign their large monolithic legacy applications into a leaner microservices based architecture to allow for more frequent application updates. These include the need to experiment/innovate quickly without affecting the core business functionalities, adapt to changing consumer demand for richer omni-channel experiences, compliance and regulatory changes, etc.

Additionally, with microservice-based architectures, application functions are distributed so that they can scale independently of one another, leading to better performance, business resiliency and ability to roll out changes more rapidly.

However, the road to microservices adoption does include challenges, such as:

  • Risk of rebuilding crucial legacy processes and applications
  • Applying the right best practices to design and build microservices
  • Understanding how to decouple monolithic applications
  • Integrating modern microservices-based applications with existing legacy
  • Governance of complex microservice architectures

As an expert in digital and cloud transformation, Virtusa works with companies to help them overcome the challenges of microservices adoption and re-architect their applications so that they achieve increased developer productivity, better application performance, and an optimized end-user experience.

Success story

Virtusa helps one of the largest American insurers adopt microservices architecture and re-imagine customer experience

Virtusa’s client had a monolithic application architecture that prevented it from building commons services across applications, which caused significant delays in delivering new features across customer touchpoints such as customer self-service and working with customer representatives and agents. Virtusa developed a robust microservices architecture that consisted of loosely coupled, small, autonomous services that could be deployed independently. By implementing this architecture, Virtusa helped the client drive agility in digital transformation. Benefits include:

  • Faster time to market – Time to develop integrations reduced by 50%

  • Improved quality – 50-60% reduction in reported defects

  • Easy-to-build platform – Developer onboarding time reduced by 50%

  • Increased business scalability – For example, OPP requests that used to take hours to calculate now processed within seconds
