Recent Forrester inquiries from enterprise infrastructure and operations (I&O) professionals show that there's still significant confusion between infrastructure-as-a-service (IaaS) private clouds and server virtualization environments. As a result, there are a lot of misperceptions about what it takes to get your private cloud investments right and drive adoption by your developers. The answers may surprise you; they may even be the opposite of what you're thinking.
From speaking with Forrester clients who have deployed successful private clouds, we've found that your cloud should be smaller than you think, priced cheaper than the ROI math would justify and actively marketed internally - no, private clouds are not a Field of Dreams. Our latest report, "Q&A: How to Get Private Cloud Right," details this unconventional thinking, and you may find that internal clouds are much easier than you think.
First and foremost, if you think the way you operate your server virtualization environment today is good enough to call a cloud, you are probably lying to yourself. Per the Forrester definition of cloud computing, your internal cloud must be:
Highly standardized - meaning that the key operational procedures of your internal IaaS environment (provisioning, placement, patching, migration, parking and destroying) should all be documented and conducted the same way every time.
Highly automated - and to make sure the above standardized procedures are done the same time every time, you need to take these tasks out of human error and hand them over to automation software.
What is one of the most important decisions infrastructure & operations (I&O) professionals face today? It's not whether to leverage the cloud or build a private cloud or even which cloud to use. The more important decision is which applications to place in the cloud, and sadly this decision isn't often made objectively. Application development & delivery professionals often decide on their own by bypassing IT. When the decision is made in the open with all parts of IT and the business invited to collaborate, emotion and bravado often rule the day. "SAP's a total pain and a bloated beast, let's move that to the cloud," one CIO said to his staff recently. His belief was if we can do that in the cloud it will prove to the organization that we can move anything to the cloud. Sadly, while a big bang certainly would garner a lot of attention, the likelihood that this transition would be successful is extremely low, and a big bang effort that becomes a big disaster could sour your organization on the cloud and destroy IT's credibility. Instead, organizations should start with low risk applications that let you learn safely how to best leverage the cloud — whether public or private.
Forrester surveys show that enterprise infrastructure and operations (I&O) teams that are well down the virtualization path are shifting their priorities to deploying a private cloud. While you can certainly build your own, you don’t have to anymore. There’s an abundance of vendor solutions that can make this easier. In response to Forrester client requests for help in selecting the right vendor for their needs, we've published our first market overview of private cloud solutions. Through this research we found that there are a variety of offerings suited to different client needs, giving you a good landscape to choose from. There are essentially five solution types emerging: 1) enterprise systems management vendors; 2) OS/hypervisor vendors; 3) converged infrastructure solutions; 4) pure-play cloud solutions; and 5) grid-derived solutions. Each brings the core IaaS features as well as unique differentiating value.
How should you choose which one is right for you? That very much depends on which vendors you already have relationships with, what type of cloud you want to deploy, where you want to start from, and what you hope to get out of the cloud once it's deployed.
Is your cloud strategy centered on saving money or fueling revenue growth? Where you land on this question could determine a lot about your experience level with cloud services and what guidance you should be giving to your application developers and infrastructure & operations teams. According to our research the majority of CIOs would vote for the savings, seeing cloud computing as an evolution of outsourcing and hosting that can drive down capital and operations expenses. In some cases this is correct but in many the opposite will result. Using the cloud wrong may raise your costs.
But this isn’t a debate worth having because it’s the exploration of the use cases where it does save you money that bears the real fruit. And it’s through this experience that you can start shifting your thinking from cost savings to revenue opportunities. Forrester surveys show that the top reasons developers tap into cloud services (and the empowered non-developers in your business units) is to rapidly deploy new services and capabilities. And the drivers behind these efforts – new services, better customer experience and improved productivity. Translation: Revenues and profits.
If the cloud is bringing new money in the door, does it really matter if it’s the cheaper solution? Not at first. But over time using cloud as a revenue engine doesn’t necessarily mean high margins on that revenue. That’s where your experience with the cost advantaged uses of cloud come in.
