Many important business applications today are based on old architectural patterns or run on older infrastructure that is inefficient, inflexible and expensive to maintain – but how are they modernized? Here are some approaches that quickly yield impressive results.

The majority of companies operate their revenue-generating services on applications based on old architectural patterns that run on older and proprietary infrastructure. Companies are aware that they need to modernize these applications to keep up with the pace required by the company. But how can they do it in ways that yield impressive results – fast?
I addressed that question in a recent CIO.com article: 5 fast winding paths for application modernization. Here is a quick summary of the five highly effective strategies that I described in the article:
1. Re-host and re-platform to hybrid cloud. Migrate applications from aging or non-strategic platforms. Consider moving mainframe and UNIX workloads, e.g. For Linux or Windows. This may require technical changes to enable custom coded applications to work in the target environment, but it does not require changes to the business logic or application language. Consider building one managed hybrid cloud with HPE GreenLake edge-to-cloud platform
Transform into modern languages and open source components using automation. Older application languages and proprietary components increase operating costs and integration complexity. With automated migration tools, you can move to modern languages and open source alternatives
3. Containerize applications so they can be inserted anywhere in your hybrid cloud property. Containerization provides true cloud-native capabilities with greater portability, faster deployment cycles, improved maintenance capability, and greater scalability.
4. Re-architect for stateless and micro-services. Use domain-driven design techniques and tools to transform traditional applications into modern applications based on microservices.
5. Re-architect to cloud-native architectures. These architectural patterns allow you to design modular applications where components are loosely coupled and implemented automatically in different environments. Applications are more elastic; resources are allocated as needed and adapted to the necessary resources.
I unpacked these approaches in more detail in CIO.com article, and I also looked at the three key principles to keep in mind when defining your modernization path. Definitely worth reading if you want to modernize your applications to the modern hybrid cloud era (See: What is hybrid cloud?).
