As organizations continue to look for ways to increase business agility, reduce costs, and improve business resilience, accelerating the move to the cloud and modernizing their legacy apps are high on CIO agendas to help their business achieve those objectives.
Cost and risk are chief among the modernization challenges faced by organizations.
Cost: Complete refactoring of applications using microservices architectures can be a costly exercise, as companies have to pay a premium to hire staff with experience in modern software development tools, re-skill their workforce and possibly outsource to speed up development effort.
Risk: Organizations already saddled with technology debt are often fearful of venturing into full-scale modernization projects due to potential cost and schedule over runs, that could impact benefit realization and return on investment (RoI).
Organizations embarking on cloud migrations have a number of choices –including rehosting and/or refactoring their on-premises monolith applications. Rehosting is often the easiest, as they can quickly lift and shift their monoliths to AWS with minimal effort, resulting in quick time to value.
With rehosting onto AWS, Wipro FullStride Cloud Services has seen clients immediately start taking advantage of the benefits of the cloud – such as getting access to elastic, on-demand scalable infrastructure; high availability of applications; and migrating managed database services.
The other choice they have is to refactor their applications into modern, microservices-based, cloud native architectures and then bring them across to AWS. While this approach will drive higher agility for the organization, it will require significantly more effort resulting in longer time to value realization.
