An established enterprise will make the vast majority of its revenue using existing systems. So, it makes perfect sense to spend 95% of the IT budget on maintaining those systems, leaving as little as 5% to invest in new technology and innovation. Therefore, the emphasis of enterprises is often a lot more towards how to modernise the existing estate rather than building greenfield applications as there may be in a start-up. This approach makes sense as going faster, saving money or doing more can all apply to existing applications.

In this whitepaper, HCL Cloud Natives Labs is sharing their perspective on application modernization and looks at three specific software development patterns to modernize existing applications.
