Many organizations are now considering a full or partial move of their services to the cloud, and have a number of choices in this area, according to research firm Gartner. Among the most common options for companies are rehosting on IaaS, refactoring as PaaS, revising for either of those, rebuilding on PaaS or replacing software with SaaS. Any of these options can be a viable way to get apps into the cloud, but which one is right for a business will depend on their needs and infrastructure.
A recent report by the company indicates that many businesses are faced with a difficult decision when it comes to migrating their applications – one that has to include consideration for both where the business is currently and where the business is going.
Each type of application movement has its own benefits that can assist a business, depending on their needs. Rehosting, for example, allows for quick system migration without the modification of underlying architecture, while refactoring allows a business to run their applications on the infrastructure of a cloud provider, giving a balance of familiarity and innovation.
Revision is excellent for those businesses that are simply looking to redesign or improve their existing code to take best advantage of current technology. Rebuilding allows for the designing of a platform essentially from the ground up, and replacement offers software delivered as a service that can take over for an aging system or one that is no longer compatible.
Each cloud migration needs to be handled differently, and IT departments must consider what it is they aim to do before making the switch. By putting in the time before moving an application, a business can find the solution that gives them the best cloud advantage.
