CIOs contemplating cloud computing aren’t just hopping on a bandwagon. Instead, according to Tony Iams, Senior Vice President and Senior Analyst at IDEAS International, they are likely to “define ... IT processes for the next 20 years.”
Speaking at an event in Sydney yesterday, IAMS said he believes a move to cloud computing – and especially internal, private clouds – is inevitable as pooling IT resources so they can be allocated to workloads is a compelling economic proposition. Not all of the technologies needed to do so are mature, he said, but the concept is nevertheless something no CIO can ignore.
He warned, however, that any tools organisations purchase must be able to manage not only hypervisors and other core virtualisation products, but also offer holistic management functions that also cover storage and networks to recognise internal clouds’ dependencies on these technologies. Dis-integrated products, he warned, may make virtualised infrastructure more complex to manage and make it harder to construct and benefit from private clouds, making the choice of virtualisation and cloud infrastructure critical.
Users are also asking, Iams said, for management tools that can oversee both public and private clouds. Few large organisations are currently using the former, he said, asserting that he knows of no large US company using a public compute cloud for production workloads and declaring the only business case he knows of for
Another key cloud issue Iams outlined is choice of hypervisor, a product category that he believes VMware leads. Hyper-V, he added, is an entirely viable product, leaving users with a choice between the current maturity of VMware and the likelihood that Microsoft will eventually catch up.
Microsoft almost certainly has the capability to do so, he said, but is necessarily slower to bring products to market because it has to take into account the many and varied ways its products have been deployed and ensure its virtualisation software does not disrupt its other products.
