?Cloud hype continues to mount,? reports David Bradshaw, a?market researcher at International Data Corporation ?(IDC), ?But underneath the hype, enterprise IT really is evolving. There are essentially two categories of cloud services ? public cloud services are available to anyone with the means to pay, while private cloud services are dedicated to a single customer or small group of customers.?
As part of its research, commissioned by one of UK?s leading IT providers?Computacenter, IDC also found out that 90% of corporate data center capacity goes unused; 23% of organizations have multiple Cloud services in full-scale use; and 8 out of 10 employees use consumer Cloud services to fill the corporate IT gap.
How do businesses decide what is appropriate to place in the cloud? Clearly the first priority is that the cloud service chosen should deliver stronger business value than alternative ways of meeting the same need, such as lower implementation costs, faster implementation, lower (or no) capital costs, better fit to business needs (particularly from using try-before-you-buy to robustly evaluate the business impact of cloud applications), lower ongoing costs, and an exit from the software version upgrade cycle.
However, there are some serious governance issues related to the cloud that can determine which vendors you can use or indeed if you can use cloud services at all.
IDC reports that these issues include:
? Data location. Cloud services (and again, particularly public cloud services) have datacenters in different countries, which may or may not include your home country, but often include the U.S.? There are issues over data being located in the U.S., (The Patriot Act is not one of them)
? Data security. Ensuring that your data is at least as safe and secure as it would be on your own servers is a key part of any vendor selection process, whether you are considering public or private cloud services, or indeed any type of service that entrusts your data to third parties
? Duties and responsibilities. When you use the services of a cloud services provider, you continue to be the data controller while the cloud services provider is the data processor.
? Portability. How easily can you take your data and processes from one cloud to another, or indeed move them back into conventional IT should you want to?
? Service level agreements. There is a considerable amount of variation in the level of service levels that vendors are willing to commit to.
The way IT is consumed can be transformed by Cloud, with benefits including cost, flexibility and agility. However, the challenge for most organizations is maintaining control in the face of the increasing consumerization of IT, whereby staff uses their own IT in preference to corporate devices and applications.
