We&#8217;re excited by all the new possibilities, but need to find a way through the minefield&#8230; which is where we end up going full circle and returning to conversations with product vendors about their vision for the future.<\/p>\n<p>What I saw in Bittman&#8217;s presentation was an analyst, albeit one who was speaking at a Microsoft conference, talking broad terms about cloud computing and how it is affected by virtualisation.  No vendor alegiance, just tell it as it is.  And <a href=\"http:\/\/www.microsoft.com\/presspass\/exec\/bobmuglia\/0908virtualization.mspx\">this is what he had to say<\/a>:<\/p>\n<p>When people talk about virtualisation, they talk about saving money, power and space &#8211; and  they talk about &#8220;green IT&#8221; &#8211; but virtualisation is more than that.  Virtualisation is an enabling technology for the trasnformation of IT service delivery, a catalyst for changing architectures, processes, cultures, and the IT marketplace itself.  And, through these changes, it enables business transformation.<\/p>\n<p>Virtualisation is a hot topic but it&#8217;s also part of something much larger &#8211; cloud computing.  But rather than moving all of our IT services to the Internet, Gartner see virtuaInternetlisation allegiancetransformationas a means to unlock cloud computing so that <em>internal<\/em> IT departments deliver services to business units in a manner that is more &#8220;cloud like&#8221;.<\/p>\n<p>Bittman explained that in the past, our component-oriented approach has led to the management of silos for resource management, capacity planning and performance management.  <img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/images\/gartner-virtualisation-silos-clouds.png?w=700&#038;ssl=1\" alt=\"Gartner: Virtualising the data centre - from silos to clouds\" \/><br \/>\nThen, as we realise how much these silos are costing, virtualisation is employed to drive down infrastructure costs and increase flexibility &#8211; a layer-oriented approach with pools of resource, and what he refers to as &#8220;elasticity&#8221; &#8211; the ability to &#8220;do things&#8221; much more quickly.  Even that is only part of the journey though &#8211; by linking the pools of resource to the service level requirements of end users, an automated service-oriented approach can be created &#8211; an SoA in the form of cloud computing.<\/p>\n<p>At the moment internal IT is still evolving, but external IT providers are starting to deliver service from the cloud (e.g. Google Apps, salesforce.com, etc.) &#8211; and that&#8217;s just the start of cloud computing.<\/p>\n<p>Rather than defining cloud computing, Bitmann described some of the key attributes:<\/p>\n<ol>\n<li>Service orientation.<\/li>\n<li>Utility pricing (either subsidised, or usage-based).<\/li>\n<li>Elasticity.<\/li>\n<li>Delivered over the Internet.<\/li>\n<\/ol>\n<p>The first three of these are the same whether the cloud is internal or external.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/images\/gartner-virtualisation-consolidation-deconsolidation.png?w=700&#038;ssl=1\" alt=\"Gartner: Virtualisation consolidation and deconsolidation\" \/>Virtualisation is not really about consolidation.  It&#8217;s actually the decoupling of components that were previously combined &#8211; the application, operating system and hardware &#8211; to provides some level of abstraction.  A hypervisor is just a service provider for compute resource to a virtual machine.  Decoupling is only one part of what&#8217;s happening though as the services may be delivered in different ways &#8211; what Gartner describes as <a href=\"http:\/\/www.gartner.com\/it\/products\/research\/alternative_delivery\/alternative_delivery.jsp\">alternative IT delivery models<\/a>.<\/p>\n<p>Technology is only one part of this transformation of IT &#8211; one of the biggest changes is the way  in which we view IT as we move from buying components (e.g. a new server) to services (including thinking about how to consume those services &#8211; internally or from the cloud) and this is a cultural\/mindset change.<\/p>\n<p>Pricing and licensing also changes &#8211; no longer will serial numbers be tied to servers but new, usage-based, models will emerge.<\/p>\n<p>IT funding will change too &#8211; with utility pricing leading to a fluid expansion and contraction of infrastructure as required to meet demands.<\/p>\n<p>Speed of deployment is another change &#8211; as virtualisation allows for faster deployment and business IT users see the speed in which they can obtain new services, demand will also increase.<\/p>\n<p>Management will be critical &#8211; processes for management of service providers and tools as the delivery model flexes based on the various service layers.<\/p>\n<p>And all of this leads towards cloud computing &#8211; not outsourcing everything to external providers, but enabling strategic change by using technologies such as virtualisation to allow internal IT to function in a manner which is more akin to an external service, whilst also changing the business&#8217; ability to consume cloud services.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In my summary of the key messages from Microsoft&#8217;s virtualisation launch last week, I promised a post about the segment delivered by Tom Bittman, Gartner\u00e2\u20ac\u2122s VP and Chief of Research for Infrastructure and Operations, who spoke about how virtualisation is a key enabler for cloud computing.
