Private clouds are not all they are cracked up to be

Cloud computing provides ‘elastic’ computing power over the internet. It avoids capital expenditure on both hardware and datacentre space. It’s a great model for start-up companies, and enterprises who occasionally need additional computing power. Increasingly, cloud services rival traditional ‘local’ and desktop software for features and performance.

Yet plenty of software vendors recommend Private Clouds to enterprises. Private clouds are operated, and only accessible, within the enterprise. Unless rigorously planned and implemented private clouds will fail to provide most, if not all the key features of cloud computing.

A private cloud will perpetuate the need to invest in physical infrastructure. You may not be able to access services from the internet due to corporate firewalls and security policy.  Elasticity of computing power – the ability to only use and pay for what you need, when you need it – will only be achievable by the largest organisations with many departments with differing and complementary demand profiles.

Is your operations team and procedures capable of providing the flexibility required to make a private cloud successful?

Often, people select a private cloud because of security concerns with the ‘public’ cloud. Before you use this as justification, you might want to consider whether your security is really better than that of Amazon, Google, Salesforce.com or IBM?
