Glossary What is Application Modernization?
By / 2 Jan 2023 / Topics: Application development
Application modernization, also known as legacy modernization, is the process of updating older software applications to change its language, framework or infrastructure platform. Additionally, many application modernization projects focus on implementing a cloud-first model alongside new technologies to simplify management and support digital transformation that expands capabilities.
These updates and migrations to public, private and hybrid cloud models target various performance and User Experience (UX) enhancements.
Performance enhancements
To achieve current and future objectives, organizations will need to adopt new platforms and make new technology choices for its applications. A cloud-first approach is a common component of modernizing an application, but organizations should evaluate on-premises options in addition to the cloud.
Organizations will also want to evaluate implementing new technologies, including open-source software (OSS), web- and mobile-based versions, and immersive technologies like virtual reality. Applications may also be integrated with other digital tools to improve security measures, enhance performance or consolidate systems onto a comprehensive platform.
User experience improvements
User behavioral data is also used to help ensure a seamless experience that meets expectations. Improving the overall user experience can leverage innovative technology like automation tools and generative AI. A human-centered design process that includes behavioral data will be invaluable to understanding what is needed for the application, so it’s used effectively and helps the organization’s goals.
Application modernization process
Every application has unique requirements that need to support an organization’s goals. To ensure alignment between capabilities and goals, organizations should follow a detailed process during the application modernization.
Some key steps include:
- Evaluating whether to retain, retire or repurchase the existing on-premises infrastructure platform
- Rehosting or replatforming the application on a cloud-based Infrastructure as a Service (IaaS) platform
- Refactoring or rearchitecting the application and data across a Platform as a Service (PaaS), managed container or serverless platform
- Implementing a management strategy, which could involve outsourcing the management burden
