Understanding replatforming

The world of cloud migration can seem daunting, and working with legacy applications is a challenge in and of itself. Various cloud migration approaches are available, and replatforming is one of the most popular.

What is it and why is it important? Let’s find out!

Definition of replatforming

Software replatforming refers to the process of migrating software applications, data, and operations from one computing platform or architecture to another. It is undertaken to enhance functionality, improve performance, or enable scalability, typically involving shifts in the underlying technology stack, data schemas, or operating environments.

This might encompass changes in databases, programming languages, application infrastructure, and more, with a goal of meeting evolving business requirements and leveraging newer, often more efficient, technologies. Replatforming enables businesses to take advantage of the benefits associated with cloud deployment models.

Unlike cloud-native architecture, which is designed for the cloud right from the beginning, replatforming involves adapting an application to better suit the cloud environment without altering its fundamental architecture.

This approach allows businesses to reap the benefits of cloud computing, including cloud capabilities and cloud infrastructure, while minimizing disruptions and maintaining the core functionality of their applications.

Why to replatform existing applications?

Why do application replatforming at all?

Well, to take advantage of cloud computing and modern enterprise software architectures, of course!

Modernizing legacy applications can significantly improve performance and take advantage of cloud-native capabilities. With a well-executed replatforming project, organizations can:

  • Improve application performance,
  • Increase elasticity,
  • Automate processes,
  • Ultimately lead to cost optimization.

We will discuss the benefits of replatforming in more detail later. For now, it’s important to note that the motivations for modernizing applications can be broken down into IT benefits and business benefits. The latter include:

  • Updating specific and problematic components of an application,
  • Transitioning away from legacy software infrastructure,
  • Streamlinig operations,
  • Intrioducting more cutting-edge, and competetive features.

Replatforming Vs. Rehosting Vs. Refactoring: What’s the difference?

While researching this topic, you may have come across terms like refactoring, rehosting, and rearchitecting. They all seem very similar and are closely related to replatforming.

So what’s the difference?

Although these strategies fall under the umbrella of cloud migration, there are important differences between replatforming, rehosting, and refactoring.

on premises existing functionality

Replatforming involves modifying an application to better suit the cloud environment and improve performance, while rehosting, also known as “lift and shift,” simply moves the application without modification. Refactoring, on the other hand, involves significant changes to the application’s code base for fine-tuning and flexibility, which can be more time-consuming and costly than replatforming.

There’s also a third, nuclear option – the complete rebuilding of an entire application from the ground up. While this is the most resource-intensive and complex, it provides the greatest strategic benefits in terms of business impact.

Replatforming is often favored by organizations because it strikes a nice balance between these three options – offering greatly expanded capabilities and a less complicated migration process.

Let’s take a closer look at these three key strategies.

Replatform vs. Rehosting (Lift and Shift)

Two different approaches to cloud migration are replatforming and rehosting.

While replatforming makes changes to an application to better fit the cloud and optimize performance, rehosting simply moves the application to a new cloud environment without any changes.

Rehosting is more suitable for:

  • relatively uncomplicated applications
  • applications with limited integrations and dependencies
  • applications where a speedy migration with minimal downtime is desired

However, a major drawback of rehosting is that it does not take full advantage of cloud-native features, which may limit the potential benefits of cloud computing.

Replatform vs. Refactoring (Re-architecting)

Replatforming and refactoring differ primarily in the extent of changes made to the application during the migration process.

Replatforming updates specific components of an application to improve cloud performance, while refactoring requires extensive revisions to the application code base for optimization and adaptability.

Refactoring is appropriate for long-term projects where the ultimate return on investment justifies the initial effort and there is time to wait for those benefits to be realized. However, refactoring can be more costly and time-consuming than replatforming, making the latter a more attractive option for many organizations looking to modernize their applications while minimizing disruption.

Five key benefits of replatforming for modern businesses

Embracing the replatforming process can provide numerous benefits for organizations looking to modernize their applications and capitalize on the advantages of cloud computing. Some of these benefits include:
