As businesses progress in their modernization and transformation efforts, many encounter significant challenges with the cumbersome performance and rising cost of running monolithic business applications. Some of these applications are systems of record that have been in place for decades and are heavily burdened with integrations and customizations. In many cases, critical workflows and business processes were designed to accommodate these legacy applications adding to user and customer frustration and hampering change. The unbundling of these large legacy applications into nimble composable services liberates workflows and processes from their technology shackles and enables continuous improvement through faster access to new services-based features and capabilities. "IDC Industry CloudPath continues to track year-over-year changes in the implementation of microservices architecture across industries and geos. What we continue to see is not only more businesses across industries turning to microservices but expanded use of microservices within the business," according to Frank Della Rosa, research director, SaaS and Cloud Software. This makes it very clear that ISVs cannot afford to delay offering cloud-native applications as this will be a primary criterion for buyers.
