Application modernization

Measure the impact of software changes, understand service health and consistently deliver great customer experiences.



As software changes increase, so does the risk of failures

Software teams often struggle to meet and exceed service-level objectives. Deployments break things. It takes too long to resolve incidents. Teams lack the proactive insight needed to anticipate and prevent potential problems before they turn into customer-impacting incidents.

Learn more about application modernization

Application modernization is the process of converting, rewriting or updating older software applications to make use of newer languages, frameworks or platforms. Also known as legacy modernization or software modernization, the typical goal is to maintain the value of the older application while migrating to a new platform that has added benefits, either for the user or the system.

There can be many benefits of application modernization, typically related to the new platform or technology that the legacy software is being ported to. Benefits for end users can include better interfaces, more stable environments, expanded integration capabilities and faster processing speed. Other benefits can include improving speed for new feature development, easier maintenance for DevOps teams, better options for redundancy and resiliency and improved scalability at a lower cost.

Common challenges in application modernization include the cost of modernization and ROI for the endeavor, change management and training on updated software, poorly refactored software that performs worse than the legacy version, overhead required for coexistence of legacy applications, and lack of holistic planning and strategy for the breadth of the application portfolio.

Some of the most common patterns for application modernization include:

  • Monolith to microservices: Moving from a monolithic legacy application, which is typically difficult to update and scale, to a microservices architecture is one of the most common types of application modernization. Microservices have many benefits including improved stability, lessened lock-in and improved ability to maintain and build.
  • Lift and shift: This pattern involves taking a legacy application and moving it to a different technology stack, platform or hosting environment. This strategy is often used for a cloud migration or moving an application to a container.
  • Refactoring: Refactoring is the process of rewriting software. For modernization, rather than lift-and-shift, it can be beneficial to completely redevelop the functionality of an application to be native to a new software or technology.
  • Developing APIs: In some cases, the best option is to leave a legacy application in place while enhancing it with new APIs that can be consumed by and integrated with other newer applications.
