Understanding application modernization

Traditional and legacy applications require significant resources to support and maintain. This can lead to higher costs and maintenance while limiting flexibility, scalability, and innovation. Application modernization is the process of updating–rather than replacing–traditional software systems so businesses can improve performance and make room for innovation opportunities.

What is application modernization?

Application modernization allows organizations to update traditional applications and virtual machines to get more from existing investments and hardware resources for strategic projects, feature improvements and new applications. Application modernization can involve rehosting and replatforming existing workloads, like those running on virtual machines, onto a modern Kubernetes platform. This paves a path for modern practices like cloud-native application development, microservice architectures, DevSecOps, and AI workloads for innovation today and scalability over time.
