What is legacy application modernization or software modernization?
Application modernization is the process of updating legacy applications to scalable, cloud-native app environments by using modern technology stacks.
Here is how Wikipedia defines the application modernization:
Legacy modernization, also known as software modernization or platform modernization, refers to the conversion, rewriting or porting of a legacy system to modern computer programming languages, architectures (e.g. microservices), software libraries, protocols or hardware platforms. Legacy transformation aims to retain and extend the value of the legacy investment through migration to new platforms to benefit from the advantage of the new technologies.
Most of the companies see application modernization as only upgrading code to the latest technology stack. But, the overall goal should be broader than this.
The overall goal of software modernization can be different and unique to the business but, it should increase the business value, better align it to current business needs and make it easily adaptable to future business needs.
More than 70% of companies have now migrated at least some workloads into the public cloud, according to Gartner research. Infrastructure and Operations leaders are considering Application modernization as the top priority, and 70% of businesses will be running their software on the cloud by end of 2024.
The application modernization is generally a large, multi-year project and requires a strategic approach. If you are considering application modernization, start from the evaluation of your legacy application and determine the approach that gives you the highest business value at a minimal cost.
