A legacy system is not always defined by its age. It might be due to the lack of support or its inability to meet the needs of a business or organization that a system is considered to be legacy. Such software is usually difficult (or impossible) to maintain, support, improve, or integrate with the new systems due to its architecture, underlying technology, or design.
We help clients to evaluate, modify, or re-engineer legacy software systems to:
- Future-proof critical business functions
- Unlock data and analytics opportunities
- Improve client and employee satisfaction
- Provide better performance, quality, and scalability
We select the modernization approach that best fits the client’s needs. Below are some of these approaches:
Total: The old system is sunsetted, and the entire system is rebuilt using new technology. It сan be built using a third-party package as a foundation layer or from scratch using standard platforms.
Gradual: A component/functional block of an IT system is replaced with new technology and moved to production as a separate application while the rest of the system remains on old technology. In time, remaining components/functional blocks are replaced with separate apps, and gradually, the entire system is rebuilt.
Duck-tape: Localized, small-scale changes are performed using new technology to address specific issues in the application while the application core architecture and technology remain intact. A popular approach is to build a new application that will be bolted to the main application to bridge the gap in functionality.
Improve existing: The existing system is modernized to offer better results through improved design. Typically, the core technology stack remains the same, or a few minor additions may be introduced.
No system change: Clients are taking a wait-and-watch approach and not going for any modernization drive or systems change.
Throughout our modernization projects, we follow key principles of business agility and apply them to realities of modern technology:
- DevOps and rapid-deployment foundation
- Infrastructure modernization
- Rapid-development and active use of solution accelerators
- Component-based vs. monolithic systems, multi-skilled, multi-functional (Business + Dev), outcome-oriented teams
- 80% of the budget is functionality, 20% is modernization as a secondary goal
