Hello, let me introduce myself to our Vendor Strategy Blog readers and participants; I am Forrester's lead analyst in Green IT. My job is to understand enterprise requirements for more sustainable IT infrastructure and processes, and especially to help Vendor Strategists in hardware, software, and services respond to those requirements.
I have been working recently with many of the largest IT services companies about their green IT and sustainability practices and offerings (Market Overview report here). Many of these service providers are of course also the big players in IT infrastructure outsourcing. In the course of discussions with strategists and marketers at these vendors, I was struck by the disconnect between their green IT services and outsourcing or cloud computing offerings. Not a single outsourcing or cloud services provider is using the sustainability angle as a differentiator or business rationale for adopting those services.
Now, clearly the "green cloud" will need some work -- first, we'll have to think up a better name! And suppliers will have to provide cost/benefit arithmetic to potential customers that spells out the green benefits of infrastructure outsourcing side-by-side with its other business case justifications like cost, rapid innovation, simplicity, and expertise. Green is not THE reason that companies will move applications to the cloud, but it can and should be A reason for such migration.
Simply put, a cloud implementation of a given application or service will have a smaller energy and carbon footprint than an on-premise implementation. Why? Because the service provider operates at greater scale, so its energy consumption per application or per transaction is lower; also, the data centers of the cloud providers are much further along than the typical enterprise in putting green IT practices like virtualization and power management in place.
And let's be clear: enterprises cannot simply offload their IT energy & carbon footprint on outsourcing providers. Customers will still be responsible for the carbon emissions done on their behalf by a service provider, just like they must account for emissions from their electric utility based on their usage. But those IT-related emissions will be LOWER than an in-house implementation.
So, a prediction, a recommendation, and a request for your input.
