Private cloud service is a last resort

Enterprise should leave private cloud services as a last resort, says Gartner, beginning their journey to cloud computing with simple apps running in the public cloud, though only after thorough analysis.

During the IT Symposium on Tuesday, Gartner analyst Daryl Plummer advised how, if you do plan on using the cloud, you should start with common apps, like email, social, productivity and Web, then work your way through to the advanced apps.

This is to limit the potential damage that might result from security, assurance and integration issues that may occur during the early stages of a project, he added.

A cloud implementation requires thorough analysis to ensure that the project objectives are well understood, he warned. Cloud usage costs are often underestimated, so the accurate cost is hard to analyse, and some companies are not seeing the savings they anticipate.

However, Plummer did acknowledge that the cloud benefits include reduced cost and complexity, more focus and innovation and agility.

Plummer delivered his words of advice following a Gartner report which found that cloud revenues will be growing over the next five years. Companies should get ahead in the movement whilst the cloud gets bigger and reaches out to more organizations, he said.

It’s predicted that software as a service (SaaS) will grow by 16.3%, as its revenue is already at $12bn this year. The biggest growth is in infrastructure as a service (IaaS), which is at $4.2bn but could grow by 45%.
