The Cloud has become the go-to computing point for enterprises these days. Many companies prefer to transition their existing apps to the Cloud, simply because of the security and efficiency benefits the platform can provide. No matter the type of IT environment within your enterprise, chances are the Cloud will prove to be beneficial.

Moving to the Cloud needs to be practical and resourceful; it does not have to be simultaneous and all at once. In other words, some applications should be run in the traditional manner, while some can slowly and steadily be transitioned to the Cloud. With this mode, one can make use of the hybrid Cloud model, wherein a few apps can work on the Cloud, while others are slowly and steadily moved over.

If you are also looking at making use of the Cloud for running your business-related apps, then it is time to check out the following options available for the process.

Re-Hosting

Re-hosting is all lift and shift since it entails redeploying apps to a cloud-based environment, where changes are made to the app’s host configuration. This type of migration is not only easy but also considered to be a quick and seamless transition methodology.

What makes this solution appealing is the use of the re-hosting capabilities with the likes of AWS VM Import/Export; however, this does not stop customers from learning as they go. In other words, once apps are in the Cloud, redesigning them to meet your current demands is an easier task. Generally speaking, re-hosting as a migration option is best suited for large-scale enterprise transitions. With such extensive scale migrations, enterprises can realize cost savings up to 30%, without having to involve any cloud optimizations.

Re-Platforming

Re-platforming is all about migrating applications, and their components, to a cloud-managed platform without having to change the core application architecture. The essential idea is to run applications on the Cloud provider’s platforms, which entails replacing the configuration of the app’s architecture, without worrying about the implementation of developer cycles.

Backward compatibility is an added advantage of re-platforming, as it allows developers to reuse known resources, without going into the nuances of new app development. However, at the same time, re-platforming is a relatively new concept and is yet to gain the necessary traction in the PaaS market.

Re-Architecting

As the name suggests, this method is all about re-architecting existing applications to run smoothly in the Cloud platforms by leveraging the features or services provided by the cloud provider. This feature usually comes into play, when an enterprise is interested in customizing and developing the software within the Cloud, to cater to new ventures or software needs. However, this comes with its own set of disadvantages, which translates into the loss of legacy codes and known development frameworks.

Despite the disadvantages, it is difficult to overlook the advantages it brings with it. When you look at re-architecting as a migration option, it opens up the enterprise’s access to a series of world-class developing tools, which are available on the cloud provider’s platform. Such advantages include the likes of pre-designed customizable templates, along with a set of data models, which can enhance productivity greatly.

Re-Purchasing

Repurchasing often means that old application platforms are discarded with the aim to purchase new ones or to upgrade to the newer versions. Through the repurchasing option, enterprises can deploy the use of SaaS platforms, such as Drupal and Salesforce.com in a more secure, efficient manner. While it comes with its own set of disadvantages, this option offers companies a better view of their app deployment strategies.

Retiring

During the migration process, an enterprise has to do a deeper dive into the list of its owned apps’ this would mean going through every app which needs to be migrated and further trying to understand its uses and cost to the company. If the company feels the app is obsolete or not worth the money and effort of migrating to the Cloud, it can be downsized, and removed from the existing kit — this not only simplifies the cost and translates into saving for the company, but also makes it better for an enterprise to promote scalability and efficiency.

Retaining

This process involves holding back applications from migration which could either attract a significant amount of time in rearchitecting to be able to run in the cloud or are not migration ready as they were upgraded recently and may turn out to be a costly affair if migrated. One may also decide to retain an application if the cloud doesn’t support the app or if there is an existing sunk cost associated with the application.

Depending on the need of the hour and the immediate uses, an enterprise can pick and choose the best available option, when it comes to migrating to the Cloud. An enterprise needs to weigh the pros and cons of the selected method and act on it accordingly. This way, there is a lot of effort which is saved in running old apps in a traditional and unconventional manner.
