Continuing the 100-day cloud watch, I’m working through my list of cloud computing surveys and papers. Given my background and primary readership, I’m starting with the enterprise architecture focused research. First up is the Forrester Report: EAs Are Seeing the Beginning of Cloud’s Impact On IT by Gene Leganza. The paper stemmed from a recent Forrester Leadership Board (FLB) teleconference:
“A recent Forrester Leadership Boards (FLB) teleconference, attended exclusively by Enterprise Architecture Council members, focused on the impact of cloud computing on EA and the traditional IT structure. We polled the 75 attendees, all enterprise architects, to determine their level of familiarity with cloud concepts and terminology, the degree to which these enterprise architects are engaging with the business and IT community to make decisions about cloud deployments, and the motivation for looking to the cloud for solutions.”
The report offers good information about why organizations are adopting cloud computing – include the different drivers of enterprise architecture and infrastructure professionals – along with enterprise architecture’s involvement in cloud computing adoption and implementation. I’d like to focus on this last point:
“Of the 54 session attendees who responded to this question, 20% said they were aware of no cloud deployments in their enterprise. Of the 43 who knew of cloud use, 26% said enterprise architects were involved in all cloud decisions, 58% said they were pulled in for guidance on possible cloud deployments some of the time, and 16% said their business or IT staff had licensed cloud services without EA’s involvement.”
Forrester surmises: “The ease of procuring cloud resources makes it likely that business project sponsors or IT development and support staff will acquire cloud services without engaging the standard technology governance processes where architects typically become engaged.”. At the Gartner AADI conference, Eric Knipp referred to this phenomenon as the rise of “Citizen Development”.
In the report, Leganza suggests that instead of “falling victim to an end run by the business”, enterprise architects need to embrace the role of business advisor. Specifically, Leganza recommends:
“Get proficient in cloud-related issues and terminology. If IT in general and architects in particular are to position themselves as trusted advisors to the business — thus playing a role in the IT-to-BT transition rather than being a victim of it — architects should be the ones to recommend cloud services when they are appropriate rather than let the business position cloud as a way to get IT services without the IT department. To be in a position to advocate cloud-based solutions, architects must have a thorough understanding of the facts, subtleties, hype, and misinformation surrounding cloud computing, and they must develop a practical model for which of their workloads are appropriate for the cloud and which must be deployed internally…”
“Look for ways to improve IT services with cloud-based offerings. Work with subject matter experts in infrastructure and application engineering to see where cloud-based services can provide hosted solutions that are more cost-effective and flexible than in-house scenarios without introducing undue risk…"
“Consider cloud services when brainstorming business solutions. Create a cloud cheat sheet — your own customized guide listing criteria that identify a workload appropriate for the cloud — for use in early-stage architecture reviews or when discussing possible solutions to business problems. Any flexible and cost-effective hosting arrangement that does not introduce risk can translate to technology-enhanced business capabilities with no increased support burden on internal IT, which is a win-win for both IT and its business stakeholders.”
“Provide a context for solution decisions with an integrated view of architecture. …Providing an easy-to-understand high-level graphical view of business, information, and applications — such as in a capability map — can enable informed discussions about possible cloud-based solutions that don’t ignore integration requirements.”
Todd Biske, a seasoned enterprise architect and renowned SOA Governance expert, also speaks to the EA as Business Advisor in a recent post.
