The Challenge
A leading industrial client needed to modernize its legacy Oracle WebLogic applications by migrating them to a Kubernetes-based microservices architecture using a multi-cloud environment. The initiative required the migration of 35 applications within a 12-month timeframe. The effort was complicated by limited internal bandwidth, delays from previous consulting partners, capacity constraints and added complexity from a recent acquisition.
How We Helped
Experis deployed a semi-autonomous consulting team that integrated seamlessly with the client’s internal resources. This collaborative model enabled efficient knowledge sharing and close coordination throughout the project.
Key areas of focus included:
- Developing and maintaining test suites using Java and the Spring framework to validate each WebLogic application before and after migration
- Redesigning and optimizing databases using Oracle and Postgres to support the microservices architecture
- Implementing Kubernetes Operators for container orchestration, enabling scalable and resilient application deployment in the cloud
The team worked closely with stakeholders to manage the transition with minimal disruption while ensuring technical integrity and alignment with business goals.
The Impact
The client successfully migrated all 35 applications within the required 12-month window, despite the challenges posed by earlier consulting delays and organizational change.
Key outcomes included:
- A fully modernized, cloud-native application environment that improved scalability and performance
- A sustainable microservices model supported by robust architecture and streamlined operations
- Continued architectural control retained by the client, supported by expert guidance for long-term success
This initiative positioned the client to scale with confidence while reducing operational complexity and improving application reliability across their cloud ecosystem.
