What is cloud modernization?

Cloud modernization is a multistep process where existing on-premises applications, infrastructure and data sources are migrated, updated and transformed into a cloud-based architecture and environment.

Simply moving an on-premises application to the cloud -- tempting initially from a time and financial viewpoint -- fails to take advantage of all the cloud offers. Besides, if the application can be moved to the cloud in the first place, it might not work correctly once it's there. A proper cloud migration and the accompanying update are required.

Among its many benefits, cloud modernization delivers:

As one of many examples, on-premises applications are written to operate at a specific level of performance. If demand increases, such as excessive use of a database application, work can slow or degrade due to overtaxed resources. The application cannot scale up to meet demand.

In a cloud-based environment, because of cloud elasticity, more hardware resources can absorb any excessive workload, avoiding performance degradation. Likewise, if demand tapers, the application can scale back resource use, saving energy and money on computing and storage needs.

There are several cloud modernization strategies to address different migration needs, each with its strengths and weaknesses. Scrutiny of each application is required to determine the optimal strategy for modernization based on a user's specific needs.

Upgrading applications and data to a cloud-first model requires forethought and diligence. There are several steps in the process, including the following:

Here are some examples of various cloud modernization projects and their unique solutions:

The terms "cloud modernization" and "cloud migration" are used interchangeably, but they are different processes. A migration involves less effort than a modernization, usually just enough to get the application working in the cloud and take advantage of its benefits. Cloud modernization is far more comprehensive and is nearly a complete rewrite of the application.

Cloud migration is a simpler process that requires less time, fewer resources and less expertise to complete. While a cloud modernization effort takes longer and costs more, it also provides more benefits. The application is far better suited to the cloud, and in the process of modernization, new features may be added, further increasing its utility.

So cloud migration is faster, simpler and cheaper, but cloud modernization delivers better long-term results. Each application must be judged on the benefits of choosing migration or modernization and which is likely to deliver the better return on investment.
