Several weeks ago, I asked TechRepublic readers to vote in two polls related to the long-term use of Exchange. The responses have been enlightening, so I decided to take a quick stab at some analysis. (The data below is based on the poll results at the time of this writing.)
For the first question, we received 443 responses, and we received 296 responses to the second question. While this is hardly a scientific poll, 443 responses is a respectable sample size from which to draw very general, broad conclusions, but with a major caveat: I suspect that the results are significantly skewed by those with favorable views of Exchange given the original article title of "What are your long-term plans for Exchange?" None of the conclusions drawn from these polls should be used beyond getting a general sense of what's happening in other organizations that use Microsoft Exchange. Further, because of rounding, percentages don't always hit exactly 100%.
Exchange plansQuestion 1: What are the long-term plans for Exchange in your organization? A total of 80% of respondents indicated that their organizations plan to remain on Exchange, although they might move to a hosted Exchange service in favor of maintaining an internal Exchange infrastructure (Figure A).

This statistic doesn't indicate overwhelming support for cloud-based Exchange, but 12% isn't exactly a small number, either. I wish I could obtain an organizational demographic breakdown to gain a better understanding of what organizations of different size and in different verticals plan to do with Exchange. For example, did mostly large organizations respond, or was there a reasonable inclusion of smaller organizations? Is education more likely than healthcare to consider outsourcing options? (Note: For this graph, I excluded the non-Exchange responses, so the graph below includes only those who intend to continue using Exchange.) Figure B

Of the 15% of respondents indicated in this graph, Exchange has never existed at their companies (8%); Exchange will soon be eliminated in favor or another solution (5%); or the company has already moved to another internal solution (2%) (Figure C).

Also, Microsoft has apparently done a pretty good job of marketing Exchange 2010, as 54% of the 433 respondents' organizations have the newest version of Exchange in their future (11% have already made the change). From there, the percentages move into the single digits, with 2% of respondents planning to keep email internal on a non-Exchange platform, 8% of respondents having never used Exchange, 7% planning to outsource Exchange, and 8% planning to move to an outsourced non-Exchange platform.

Virtualization plansQuestion 2: For those keeping Exchange internal, what are your virtualization plans for Exchange?
The responses to the second question form, theoretically, a subset of the Exchange-positive answers from the first question. However, bear in mind that some people who are moving away from Exchange or have never used Exchange may have also responses, thus skewing the possible results a bit.For this question, we had 296 respondents, with 33% indicating that their organizations have no plans whatsoever to virtualize their Exchange infrastructures. Slightly more than 1/3 (36%) indicated that they have either virtualized all of their Exchange infrastructure (28%) or a portion of their Exchange infrastructure (8%). Another 31% indicated that their organizations have plans to virtualize some or all of their Exchange environment but have yet to begin the project. (Figure E) Figure E

Again, depending on how people interpret the question may lead to a variety of reasons that the results turned out the way that they did. I was stunned to learn than 28% of respondents have fully virtualized Exchange. I expected to see a double-digit number, but I did not expect it to be quite that high. This is another case where respondent demographics would be invaluable. Are the people in the 28% group all small, single-server organizations?
My organization, Westminster College, falls into the 8% that have virtualized some Exchange services.
I wasn't surprised at all by the fact that 31% of organizations plan to virtualize Exchange, especially with Exchange 2010's virtualization friendly I/O footprint.
In short, fully 2/3 of Exchange organizations are virtualizing or plan to virtualize some or all of their Exchange environments. What a different world it is from just a few years ago when virtualizing Exchange 2003 was certainly not considered a best practice. It's obvious that many organizations understand the benefit that can come from adding Exchange as just another service on top of the virtualization stack.
From this information (even though it was derived from an unscientific survey), you can glean general trends from the actions of other organizations to help you dictate your own course. The phrase "where there's smoke, there's fire" can mean a lot. For instance:
- If 2/3 of Exchange shops are virtualizing or are considering virtualization, for example, there must be something there worth investigating.
- If you're wondering about Exchange's future in light of competition from others, it looks like you don't need to worry too much. Although there are competitors out there and there will be defections from Exchange to other platforms, many organizations are staying on Exchange, even if a number of them are considering new delivery models (e.g., the cloud).
