How many multisite installs are out there, anyway? In a recent forum post unrelated to multisite but using those numbers for comparison, Jane gave some numbers:
We can’t really get very accurate stats, because we only know about *installs* that phone home, not number of users on each one who might need the multisite menus. We know of about 60,000+ multisite installations, half of which have more than two sites. The average is 58.7 sites per multisite install (that gets us into the 3.5 million sites mark, times however many users per site). Then, 31 installs have more than 10k sites. Edublogs, for example, has over a million sites. Universities like CUNY have thousands/tens of thousands of users per install.
And a bit later:
Better stat courtesy of @nacin:
“Chop off the 31 sites > 10,000 sites, chop off the 30,000 sites <= 2 sites.
96.3979 average for the remaining 30,000 networks."
I actually talked to Nacin about these numbers back in July at WordCamp Montreal, so these stats are not surprising to me. Seems a little low though – what do you think?
Hey thanks for stopping by my blog earlier. I recommend not using WordPress multi-site because if an update goes wrong, like that Rotten WordPress 3.3 and my TLD blog, then all child sites and downline sites are affected.
However, I do think WP multi-site is good in the hands of responsible admin. And…be sure to have a separate update testing blog/site if you do put all your eggs in one basket and decide to roll with WP multi-site.
And use the testing site because I am an idiot!
Why is it surprise? wordpress multisite have poor support.. even there is no tutorial how to use multiserver for media uploads.. or even no support for multiserver upload system tbh..
why should people build big networks with wordpress?
WordPress.com does and they seem to be able to offload media just fine. There’s already the info out there to host the entire wp-content folder somewhere else.
can you give just 1 example article that explains using multi server for multisite blog uploads? Thanks a lot
I’m sorry if this doesn’t answer your question, but I have a few bookmarks that *may* be relevant
1) Appendix 8 “Cloud hosting” in the O”Reilly book “Head First WordPress” by Jeff Siarto, and
2) Amazon cloud formation templates (Highly Available Web Server with Multi-AZ Amazon RDS Instance) at http://aws.amazon.com/cloudformation/aws-cloudformation-templates/
Sok
Lets say 1 server have 1000gb space. I want to have 5000gb media upload space for multi blogs with using 5 servers on same WordPress MultiSite. This is not about Highly Available Web Server imo..
I think a lot of people use multiple separate installs when they want multiple blogs. WordPress doesn’t explicitly promote the use of multisite within itself, so most users would be unaware. A lot of people use “automatic installers” for WP (such as Fantastico etc) which also creates separate installs for each blog.
(side note: the green text in the comment box is really painful to read.)
