Cloud App Modernization

When modernizing an application for the cloud, it can mean different things to different people. While users hope for improved experiences, higher reliability, faster performance, and more frequent feature deployments; architects and developers have different answers. The optimal choice isn't always obvious because there are several technical approaches to application modernization.

The factors to consider for cloud app modernization include top-level modernization options, which include minor differences from one source to another. When modernizing, organizations must consider the impacts on business operations and users. Factors to consider also include identifying and knowing which applications should be lifted and shifted, refactored, or rewritten and in what order.

Strategies for Cloud App Modernization

Some of the common strategies that businesses consider for cloud app modernization include:  

  • Retiring

An application that no longer provides value can be retired completely, provided that retiring the app will have no impact on business operations.

  • Replace

A custom-built application may have answered the business needs of yesterday, but often these are challenging to maintain and difficult to integrate with other applications. In some situations, replacing an existing application with a pre-built app from a third-party vendor is the right move, from a cost, features, and/or integration standpoint.

  • Relocate

Also known as ‘lift-and-shift’, relocating applications from an on-premise data centre to the cloud, or between public, private, or hybrid cloud may answer some needs for better flexibility, security, and cloud management.

  • Replatform

Replatforming is much like relocating, involving moving legacy applications to the cloud. However, with replatforming, some changes are made to the application prior to the move, to make better use of cloud capabilities.

  • Reuse

The use part of reuse refers to the back end. If the back-end functionality is good, it can still be used, but cloud app modernization would involve restructuring the user experience.

  • Rebuild

Improving functionality and reducing technical debt are priorities for some applications. This would be categorized as rebuilding the application.

  • Refactor

Restructuring the existing code but leaving the front end UI as-is can help to improve application performance and functionality.

Modernization requires careful balancing of speed to market with scalability, cost optimization, mitigating future technical debt, and operational downtime. Organizations should retire apps that are no longer valuable and replace apps with SaaS, commercial, or open-source options. Apps meeting business needs and running on supportable software stacks may be candidates for relocation to cloud environments.
