Legacy Software Modernization Market Growth Drivers: What Factors Are Accelerating Expansion?
The increasing embrace of cloud-based platforms is projected to fuel the expansion of the legacy software modernization service market in the future. These platforms are defined as internet-delivered infrastructures and services offering computing power, storage, and software applications, bypassing the need for local servers or devices. The rising uptake of cloud solutions is attributed to their inherent scalability, which facilitates adaptable resource allocation and improved cost-effectiveness. Legacy software modernization services play a crucial role in promoting cloud adoption by converting older systems into architectures ready for the cloud, featuring scalability and smooth integration with current cloud platforms, thereby boosting performance, adaptability, and organizational agility. As an illustration, AAG IT, an IT services firm located in the UK, reported in January 2025 that approximately 63% of small and medium-sized business (SMB) workloads and 62% of SMB data were anticipated to reside in public clouds by 2023, representing an increase from 57% of workloads and 56% of data in 2022. Consequently, the increasing prevalence of cloud-based platforms is a primary factor driving the expansion of the legacy software modernization service market.
