Modernize legacy systems to gain a competitive edge

Legacy applications provide business-critical functions within the enterprise application landscape but incur huge maintenance and running costs. Legacy systems pose many challenges, including the risks of running on potentially unsupported hardware and software, inflexible and closed architectures, scarce talent pool, and higher SLA due to non-real-time architecture options.

Nous’ legacy application modernization services enable organizations to transform time-tested legacy applications to newer technologies and architecture to deliver greater business value. We help move individual legacy applications or an entire portfolio to modern platforms that offer rich functionality and flexibility.
