In my last post we looked at some practical ways IT could respond to the changing domain of application delivery and management that SaaS has introduced.\u00a0 This time we turn our attention to the emerging discipline of ITaaS. Although the term ITaaS has been in circulation for a number of years, a concrete and consistent definition still eludes the industry.\u00a0 A quick online search will reveal as many definitions as there are search results and a tell-tale absence of a Wikipedia entry\u2026<\/p>\n
<\/div>\n

Despite the nebulosity of the term, there\u2019s no doubt that ITaaS continues to gain momentum in the industry – more and more vendors are talking about the capabilities of their products in terms of how they support ITaaS and the major systems integrators are starting ITaaS practices. It\u2019s time to get curious about what it is and what it means \u2013 because it\u2019s coming soon to an IT department near you\u2026 <\/p>\n

<\/div>\n
<\/div>\n

An attempt at defining ITaaS<\/strong><\/p>\n

<\/div>\n

Here goes\u2026<\/p>\n

<\/div>\n

\u201cA service oriented approach to the consumption, organization and delivery of information technology such that all details of the service are abstracted from the business consumer except the service\u2019s: function, capacity, cost and agreed level of performance.\u201d<\/p>\n

<\/div>\n

OK, so that\u2019s just my attempt to formally collate and document what the various descriptions of ITaaS have in common and capture their shared ultimate goal.\u00a0 Notably almost all parties involved all have shied away from a definition so far \u2013 so this could be a first! Hopefully the key idea is clear \u2013 this means true service oriented provision of IT services to the business.<\/p>\n

<\/div>\n

ITaaS draws upon some incredible recent advances in infrastructure technology \u2013 where whole blocks of computing ,software and storage capacity are provisioned and de-provisioned with a single click, often by someone who knows nothing of the underlying complexities involved.<\/p>\n

<\/div>\n

ITaaS also unifies this incredibly dynamic infrastructure capability with the latest thinking (and supporting applications) in service level management, costing and chargeback. The business in essence buys capacity in the capabilities it needs at an agreed level of service \u2013 which it can then access with almost total ubiquity on devices of its choosing.\u00a0 By the way, ordering and configuring these services is intended to be as complex as operating the Amazon.com interface.<\/p>\n

<\/div>\n
<\/div>\n
<\/div>\n

In conclusion: The 3 key Tenets of ITaaS<\/strong><\/p>\n

<\/div>\n

So hopefully we now have a pretty good working definition of ITaaS \u2013 or at least enough to know what the characteristics and the end game of this concept are. Let\u2019s conclude by reminding ourselves of the three most significant tenets of ITaaS:<\/p>\n

<\/div>\n
<\/div>\n

<\/em>1. Massive<\/em><\/strong> Abstraction<\/p>\n

<\/div>\n
As referenced in the definition above, in ITaaS – everything about the design, delivery and management of an IT service is abstracted away from the business. The use of business language, in place of technical terminology, will be one of the fundamental characteristics of this paradigm. Moreover, thanks to the latest advances in dynamic infrastructure technology, most of the underpinning technology is itself an abstraction!<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n

2. Self-Service<\/p>\n

<\/div>\n
In ITaaS self-service is a critical concept \u2013 controlling complex systems provisioning will boil down to a couple of key questions: What do you want? And how much do you need ?. This is clearly a question a business function can answer and provided they understand (and accept) what this will cost \u2013 and can operate a self-service portal – they will be able to consume whole chunks of IT capability on demand.<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n

3. Service Levels and Charge back<\/p>\n

<\/div>\n
IT\u2019s role shifts to being one of \u2018Service Broker\u2019 with ITaaS \u2013 thanks to abstraction and self-service, IT will focus on defining the agreed service levels surrounding the availability and performance and allowing the business to dynamically select the level of coverage needed. In keeping with the abstraction theme, IT will present an all inclusive charge to the consuming business unit for the capacity used without the need to refer to what that bill comprises…or so the theory goes.<\/div>\n
<\/div>\n
<\/div>\n
<\/div>\n

Next time we\u2019ll uncover more about what it will mean to work in IT as ITaaS gains momentum: we\u2019ll expand more on the idea of becoming a \u2018Service Broker\u2019. We\u2019ll also consider what the challenges for IT will be and what some of the proposed benefits of ITaaS are.<\/p>\n
