The 4 Rs of Middleware Modernization

Many enterprises are well on their way to digital transformation – others are only just beginning. But cloud-first strategies demand a lot from middleware, and legacy middleware platforms weren’t built to address the needs of modern, hybrid IT environments.

This means that enterprises need to migrate those legacy platforms to ones that can run on-premise, in the cloud, or in a hybrid environment.

Before you can migrate legacy middleware, enterprises need to determine how they’re going to modernize. There are multiple journeys to middleware modernization, and there is no “one size fits all” approach.

Enter the four Rs of middleware modernization.

Rehost

Also known as “lift and shift,” rehosting means that developers are transferring servers or software from the current environment to a public cloud infrastructure. For those enterprises that are just starting a modernization journey, rehosting is the standard strategy.

This option doesn’t require modifications to code, features, or functions. Business logic is preserved and data is migrated to the cloud; the only requirements are the replacement of middleware, hardware, the operating system, and the database. It’s often used as a step to eliminating expensive legacy hardware.

Refactor

Each application has its own design, which means that every application will work differently in a cloud environment. In order to optimize functionality in the cloud, existing middleware may need to be restructured and the code optimized to take better advantage of cloud-native functionalities. This helps remove technical debt and improves nonfunctional attributes.

Unlock Your Potential with Application Modernization

Application modernization is a growing area of focus for enterprises. If you’re considering this path to cloud adoption, this guide explores considerations for the best approach – cloud native or legacy migration – and more.

Get the Guide

Refactoring is a time-consuming method to middleware modernization, but sometimes, there is no other way to address it.

Replatform

Similar to rehosting and refactoring, replatforming moves applications that are already in the cloud to a different cloud environment without making any major changes to the application. Examples of replatforming include upgrading the application to work with a cloud-native managed database, changing the operating system(s) or middleware it will work with, or containerizing applications.

Replatforming enables enterprises to increase scalability and improve developer productivity.

Replace

When an application is no longer needed in a cloud environment, it might make the most sense to decommission it. Oftentimes, changes are required to better suit the new environment. Reasons for replacing an application include limited value, its capabilities are duplicated elsewhere in the environment, or it’s more cost-effective to replace it with a different application than to migrate it.

What is Middleware?

Middleware is software that provides common services and capabilities to applications outside of what’s offered by an operating system. Middleware makes it easier for developers to build applications. Data management, application services, messaging, authentication, and API management are all commonly handled by middleware.

For organizations with multi-cloud and containerized environments, middleware is a cost-effective option for developing and running applications at scale.

Modernizing Middleware with Red Hat

Red Hat Middleware is a leading set of digital transformation tools that helps enterprises improve the features, reliability, and security of middleware platforms.
