Applications that don’t make sense in the Cloud

Last week, Gary White posted a blog entitled, “3 Compelling Business Reasons for Moving to the Cloud.” I’d now like to present why some applications DON’T make sense in the cloud and here’s why. I’m seeing a lot of clients who have bought into the idea of the cloud. Most of them are eager to start with a private cloud and think about extending it at a later phase to a managed or public cloud. They typically want to start with a technical proof of concept and with today’s technologies from HP like Cloud System Matrix and CSA it’s easy to demonstrate technical feasibility. But that’s where the actual problem starts. Just because something works from a technical perspective doesn’t mean that it makes good business sense for an organization.

 

In order to profit from the cloud, business applications need to profit from automation, standardization, scalability, and flexibility. And there are many applications that do not have this criteria as a priority. The big mistake many organizations are making is not properly segmenting their applications into potential cloud and non-cloud applications. They also often select applications that can easily be deployed on a cloud test system without looking at the requirements.

 

Just because an application can be easily virtualized, doesn’t necessarily mean it‘s a good cloud application.

Our recommendation to clients is to use this 3 step approach:iStock_000019680099Small[1].jpg

 

  1. Define the cloud strategy. Every organization needs to define its cloud strategy to ensure that it is aligned with its business and IT strategy and not necessarily with what is technically available in the market.
  2. Build the organization’s cloud architecture. Based on the cloud strategy, define the target architecture, both business and technical, that best meets the needs of the business and IT.
  3. Run a proof of concept. The proof of concept (PoC) is based on the target architecture which is linked to the organization’s strategy and therefore highly relevant for the organization.

After taking these inititial steps, it’s possible to run a cloud suitability assessment that will determine which applications are suitable or not suitable for the designated cloud environment. Based on the selected target platform, applications with low-latency requirements or requiring a lot of customization might be considered not suitable. Depending on the results, one can then start to tweak the cloud environment or the applications to make them more suitable or make a decision to keep the applications in separate environments.

 

There is no definitive list of applications or business areas that are not suitable for the cloud. Every organization needs to run through the above-mentioned process to determine what makes sense. But one thing is clear – not everything should be moved to the cloud. It may not provide any additional benefits or it might not be financially viable to do so. Therefore, assess the applications portfolio with regard to the company’s strategic context before you begin.

 

By eliminating the applications that don’t fit, your cloud will be much more successful. And just because an application is not in the cloud, doesn’t mean it has no future. Organizations that understand the benefits of different target environments get the best out of their converged environment.
