Cheat Sheet: Private cloud

How having your own slice of the cloud could be the way forward...

...businesses don't have to pay a service provider to access the infrastructure. They simply pay for the technology and services to help them create the private cloud, and maintenance costs after that.

What about private clouds in third-party datacentres?
Private clouds hosted by third parties offer the benefit of reducing the amount of resources businesses need to devote to managing their infrastructure.

Another business concern addressed by hosted private clouds relates to security and the location of data. Public cloud often uses a multi-tenancy approach in which numerous organisations have their data stored and processed side by side in the same datacentre and sometimes on the same physical servers.

Some businesses, particularly those operating in heavily regulated industries, aren't comfortable with the idea of their data being held in such close proximity to that of other organisations and not being able to know where it is at any one time.

Hosted private cloud services keep data separated from other organisations, providing dedicated hardware and services to the customer, while reducing the albeit minimal risk of data getting into the wrong hands.

So what's involved in moving to a private cloud?
Businesses need to start by working out which applications would benefit from being delivered by a private cloud.

For example, applications that are subject to sharp increases in demand, such as an e-commerce system, would benefit from the instant scalability that a private cloud infrastructure would provide.

Bespoke applications that differentiate businesses would be more suitable for running inhouse, while more generic applications could be better located in public cloud environments.

Once the applications have been selected, businesses need to standardise hardware and software stacks so the technology is well integrated to enable the pooling of resources to be efficient and cost-effective.

Management of the private cloud and the formulation of suitable user policies are the final - and potentially most important - steps for organisations to take if they're going to get as much out of their private cloud environment as possible.

Which tech vendors are helping businesses create private clouds?
Most of the big vendors - CA, EMC, Fujitsu, HP, IBM, Logicalis and Microsoft - provide services to customers to help them...
