Legacy modernization is a process that involves transforming legacy systems to reduce IT environment complexity and costs, increase data consistency, enable collaboration across platforms, and improve process flexibility.
EXPOSE, DECOUPLE, EXTEND
Through Cloud Native and portable, self-contained REST API’s portfolio:
Expose the legacy business functionalities in a structured, modern and interoperable approach.
Decouple the complexity, untangling the monolith for an easier comprehension and evolution.
Extend the capabilities through new features added to the business with no impact on legacy code.
Replace legacy software with new applications using modern and less costly technologies through three methodologies:
Offload mainframe transactions to Cloud Native, portable and self-contained Java-based Containers, reducing costs while maintaining the same functionalities.
Maintain and Develop the code base in COBOL or JAVA at the same time, leveraging on traditional and new resources and capabilities.
Package business functions in Cloud Native stacks, reducing the infrastructural dependencies while achieving flexibility and scaling.
Each decision should be driven by the creation of value though a risks/costs/opportunity analysis.
Modernize business systems with the aim of creating solutions that can be integrated with the current systems and future ones, without hard lock-ins.
In the future, it should be possible to maintain and improve the existing solutions.
Create ad-hoc modernization solutions that adapt in a flexible way to the needs and complexities of each customer.
While legacy modernization is not a “new” topic, innovative solutions and methodologies allow for a modern approach to the problem.
A successful project and customer satisfaction can often be achieved through a strong partnership with the right partners.
Modernization is a journey, it has to be sustainable both in a financial and technical way for keeping the right momentum though the whole voyage, overcoming complexities and road-blocks.

How does it work?
The legacy monolith is split in blocks and rehosted grouping connected functions, the underlying functions are exposed, decoupled and extended trough modern and reusable API’s.
Finally, single components can be rewritten or replaced in a composable business approach while maintaining the original code-base and features where needed.
Legacy Modernization Journey
By decoupling and untangling the complexities risks are greadly reduced early on the journey.
By offloading mainframe infrastructure from the beginning, costs are reduced early during the journey.
EASE OF INTEGRATION
Legacy functions are readily available for integration with other systems.
BETTER TIME TO MARKET
Agility on developing new features is achieved earlier then with other approaches.
