The Five Rs to Escape the Buccaneering of Technology On-Premises

Continuing to run technology on-premises leaves you open to dangerous high-seas threats from power pirates and efficiency buccaneers. By grabbing the opportunity presented by managed services experts in London, you can navigate safely, weathering storms and keeping your fleet afloat. Just remember the 4 Rs and understand the keys to migrating to the cloud.

The Five Rs

There are different ways to approach migration to the cloud. The easy way to understand them is by remembering the five Rs:

1. Rehosting

The simple and quick way to move your technology from in-house to the cloud is to rehost. This means you simply lift everything— lock, stock, and all barrels — from the physical and/or virtual servers you’ve been running to the cloud using Infrastructure as a Service (IaaS). Rehosting has its benefits, such as speed and simplicity. But it leaves you unable to enjoy some of the more powerful benefits of shifting from in-house IT systems, such as scalability.

2. Refactoring

Using Platform as a Service (PaaS), you can refactor your on-premises technology to utilize a cloud provider’s platform. The ease of this migration is that your developers and engineers can stick with tools they’re used to. You also benefit from some of the other advantages of the cloud. However, you risk being locked into a framework and you still miss out on some of the greater capabilities available from migrating to the cloud.

3. Revising

Update or replace your existing code base to fully exploit the opportunities available in the cloud. This can be the most effective migration in terms of benefiting from the cloud, but it can be the most difficult in terms of time, cost, and complexity.

4. Rebuilding

Re-engineer and rebuild your functionality on PaaS, discarding your existing codebase. This is the most powerful way to exploit the advantages of managed services in London, and it gives your team the chance to use better tools. Being so dedicated to your provider’s platform can leave you locked into difficult or expensive changes in their offering.

5. Replacing

This approach involves dumping your own application and replacing it with commercial software provided as a service. On the plus side is potentially big savings in terms of the development team needed to support technology on-premises. Finding the vendor service that suits you and avoiding lock-in can pose challenges, however.
