Refactoring legacy applications for the cloud

At Trianz, we help business leaders make many company-altering decisions when it comes to the specifics of their digital transformation plan. Perhaps the most central decision we participate in, when it comes to cloud migration, is how to move their legacy applications.

Let’s break down the options:

Rehost: lifting and shifting applications and operations from one environment to the other—while leaving the application itself unchanged.

Replatform: moving assets to the cloud with only minor up-versioning.

Refactoring: re-architecting and re-coding portions of an existing application to better adapt to cloud framework and functionality.

In the past, organizations almost always defaulted to the lift-and-shift model. It was a quicker, less resource-intensive process.

Today, forward-thinking companies that value agility tend to go with the approach that will give them their best shot at long-term success: refactoring.

Though it may call for a greater upfront investment in terms of time and resources, the end benefits are manifold:

  • Leaves you with a lower monthly spend
  • Allows you to take full advantage of cloud-native features
  • Enables you to maximize operational cost-efficiency in the cloud

How does refactoring work?

Refactoring is essentially the act of breaking down a specific business process into smaller bits. These bits can then be reinforced with new-generation, cloud-native applications. The transformation into old, off-cloud legacy applications into modern, cloud-supported applications enables IT to quickly deploy new functionalities in response to company or customer needs.

Is refactoring always the right choice?

Although the benefits to refactoring versus rehosting or replatforming are obvious, it doesn’t mean that it will be the right choice for every organization 100% of the time. This is where Trianz consultants step in.

In collaborating with us, we’ll help you draw out a rock-solid cloud migration plan that makes sense for you, whether it be via a single approach or hybrid. We’ll analyze and lay out every aspect of the migration, from upfront investment to anticipated ROI so you’ll know exactly what to anticipate in terms of results and at what cost.

Trianz accomplishes all of this by leveraging our multidisciplinary teams’ vast technical and business experience. Our holistic, big-picture approach results in strategic initiatives, often over-delivering in terms of business results, while meeting the traditional project metrics of an application refactoring initiative.
