Notes de l'éditeur
- In fact, in our survey of over 1,000 CIO and Business Leaders, they pointed to several factors which can help them reduce costs, achieve faster time to value, and improve reliability. 77% of the respondents rated factors attributing to reducing costs as a major inducement – including reducing spending on software licenses, hardware, labor, support and maintenance. Ranking next were factors that contribute to time to value, including faster deployment and scalability. And 50% of respondents said they would value improving reliability and availability.
- This should also involve discussion with the client on the appropriateness of these adoption patterns for them, the rationale, etc… If the client entered the workshop with ideas about their strongest cloud affinities, this can be discussed in light of the outcome of the tool. If the tool produced a similar answer, this might affirm the client’s opinion prior to the workshop. If the tool produces a significantly different answer, then discussion might be in order. Given what the client is trying to accomplish, have they chosen realistic cloud adoption patterns?
- Clients interviewed showed a much stronger preference for private clouds than either public or hybrid delivery models. Nonetheless, we believe that the preference for public cloud services will grow over the next few years. The companies that did show of preference for public cloud in our study display certain common characteristics. They are: More likely to be using a provider for traditional outsourcing of infrastructure and/or business processes Less likely to view loss of control over IT resources as an obstacle to acquiring Public Cloud More likely to view application/database, availability, and incident/problem management as critical processes for their business and More likely to be US businesses
