I understand how some criticize the decision to run CentOS instead of the actual supported RHEL package, but we'll have to agree to disagree. While everyone banters about the different costs they pay for their favorite version of the 'real' Enterprise package, the fact remains that there *ARE* paying Network Edition customers out there that feel comfortable running CentOS, and may prioritize their budget dollars to things that actually mean a difference to the end users they support - not the least of which is the cost of servers, storage, power, bandwidth, security, CUSTOMER SERVICE, etc.
In my own experience around sizable RHEL deployments, I've never received anything close to equivalent value for the amount of money that changed hands on an annual basis for RedHat support. I understand that a lot of corporations spend that extra money for official support as an insurance policy, and to show a measure of due diligence and compliance with certain regulations that govern such entities. There's nothing wrong with incurring such an expense, it's just a different ROI calculation with a different payback than I have for my business.
These threads are the reason I opened the feature enhancement in bugzilla. Bug 23487 - Official Support for ZCS Network Edition on CentOS was meant to be a place for those Network Edition users who want to stand up and be counted, to make their request for official support through the official feature request process Zimbra has provided, nothing more.
I really think that the idea of pawning a CentOS build off on the community as a FOSS initiative is disingenuous and a slap in the face to Network Edition customers asking for this enhancement as PAYING CUSTOMERS.
If enough of Zimbra's customers are asking for this build, then maybe it's time Zimbra to bite the bullet and prioritize an official supported build for CentOS.
It's been less than 24-hours since I filed the bug/enhancement and so far 25 Zimbra customers have voted for it. Now I'm not a heavy Bugzilla user, but that seems like a lot of votes in a single day.
If I were in the shoes of Zimbra's product manager, I would very seriously start looking at all those install reports/notifications that you receive at the end of each install process. You might be surprised by what you find . . . then again, maybe the CentOS users are a minority after all but only Zimbra has the data to back that up, the rest of us are just guessing based on our own experience and the postings of others in this forum . . .
Personally, I'd be very interested to see aggregate data of the most popular platforms in use to host Zimbra, you guys care to share??
