As the pace of technological change has increased, many organisations have found their application estates have built up significant technical debt. Constrained budgets, shortage of experienced staff and a pressure to focus on functional delivery over and above technology can lead to applications whose architectures may be considered legacy at worst, or in need of attention at best.
As businesses seek to remain competitive and deliver new product and services to market rapidly they demand more from IT. Where an internal application(s) has traditional monolithic architectures or have lagged behind the pace of technological change, then legacy technology stacks can impede the growth of a business growth and its ability to respond to market disruption and the demand for product and service innovation.
Therefore, in order to remain competitive, it is important that organisations look to replace their legacy systems.
