For my regular readers, you may have noticed that I've been talking a lot about cloud computing recently. In particular earlier this week I wrote about the impact of VMware's vCloud API announcement.
So I thought I'd take a moment to write about why this is relevant to ITIL and ITSM practitioners.
In a nutshell, the vCloud API makes all clouds, public and private,
look the same to a service catalog tool. In other words, as you work
in defining your service catalog, as long as you ensure certain
attributes are there, that request can be provisioned automatically by
any service provider who supports that interface: internal or external.
This has big implications for the future operating model of IT, and that includes the usage of ITIL processes. Luckily for me, Randy Bias, wrote an excellent blog entry about it. So I'll quote a few parts and comment and recommend that you read the rest.
So let's start here:
Cloud Computing as Business Enablement
One of the core propositions of cloud computing that I regularly
espouse is the notion of ‘cloud’ being an operational process change
and NOT a technology or simple outsourcing. This is frequently lost in the hype around ‘auto-scaling‘ and such. By an operational process change I mean two-fold:
- Creation of ’self-service’ IT for cloud consumers
- Extensive automation for IT itself, allowing a self-service delivery model
By ’self-service’ I mean: on-demand, pay-as-you-go, and
use-only-what-you-need. By automation, I mean removing the human
element in provisioning and managing IT infrastructure.
Whether you realize it or not, right now IT is largely a craftsman’s
trade whereby apprentices learn from masters. It has been unable,
despite the best intentions, to evolve into a disciplined profession
like manufacturing by itself without a forcing function.[1]
Cloud computing is that forcing function and CIOs everywhere are waking up to it.
This is the first place where your work in creating a service catalog really becomes very important or not. For the cloud operating model to work, we must do away with the notion of a catalog as a document, and focus on the service definition as an atomic product that can drive delivery and provisioning automatically. And as Randy says, that delivery needs to be thought from an automation perspective rather than the traditional back and forth of a change management process.
(By the way, at VMworld I saw more people talking and showing self-service than at last year's ITSMF show. And service catalog was lauded as key enabler during the key note -- I haven't seen that at any ITSM show yet.)
We are looking to deliver these environments in minutes and hours, not weeks and months.
He goes on to say:
Perhaps more importantly, to derive the maximum value from cloud
computing’s disruptive force, we must have standards. De facto or
otherwise. How would the railway systems work without standard track
gauges? What about telecommunications systems? Or the national power
system? The answer is that they can’t.
Standards are critical to the success of cloud computing and it’s
ability to transform IT into a business enabler that can be run
transparently like many other parts of the business.
The data center can no longer be a black box!
Randy is referring to the vCloud API, but the reality is that you need more standards than just that. First, IT needs to get its house in order and figure out what are the standard service packages, model the service components, create bundles out of already-automated atomic services to then drive the usage of these cloud services.
Compare what I'm proposing to the traditional 15 page spreadsheet of endless questions that 12 people around a table have to meet for in order to get the datacenter to provide an environment. That's going the way of music industry.
Since this is a blog about ITSM and ITIL service catalogs, I thought the following quote is a good provocation.
Some will point at ITIL or CoBIT, but the reality is that
documenting ‘meatcloud’ processes is not the same as removing the human
from the equation; IT is more similar to manufacturing than to the
legal or medical professions. The legal and medical professions are
predicated on delivering a certain kind of human talent or skill.
Manufacturing and IT are infrastructure and must be predicated on
delivering repeatable, measurable, business value.
I agree with the sentiment. For me, this means stop looking at the service catalog as documentation project and start looking at it as an automation project. Not for the whole thing, but certainly for some parts like server, network and storage. Many customers have been doing identity and desktop for a while; it should not be a revolutionary step.
But let's hold a second with the hype, lest you think my head is going cloudy. I do believe this change is going to take a while, but I don't believe it'll be gradual.
What I'm seeing is that IT organizations are now thinking of cloud and making some plans to play, but the sudden change in economic fortunes and subsequent layoffs have forced the new team to adopt cloud computing for applications that as little as 6 months ago it would have been unimaginable. It's not that IT leadership changed, rather IT leadership GOT changed.
There will still need to be many governance and control steps which will be manual, but ... even many of those can be addressed by a service catalog that implements good Role Based Access Control and service profile policies. Translated to English, it means that rather than manual steps, the catalog figures out what services you are allowed to use and the constraints and changes you are allowed to make.
Essentially, it's a set of pre-approved policy driven requests. Need a small linux testing for 30 days and you are a QA person? Boom, you got it. Don't even need to approve it because the policy says you have the right and capacity has been reserved for QA. Of course, you better have figured out what your service is and who are the customers of that service.
So what does this mean to you today? This is a topic I'd like to write more about, but here are my early thoughts in no particular order.
- ITIL practitioners should be be talking closely the server and virtualization folks to close the gap. They may turn out to be your best allies.
- I'd think hard about the utility and value of the service catalog as a cloud enabler. It is absolutely going to be; the question on the table is, will it be yours?
- I'd start asking my vendors to show you how they are preparing to meet this new opportunity and how they can guide you in your project.
- Personally, I'd spend some time getting acquainted with Amazon -- it's a credit card away and pretty cheap -- to get some sense of what works. If you are technically inclined, read the vCloud API intro.
