I'm wondering if anyone is willing to provide some input and suggestions, as we're wrestling with some strategy decisions.
We are launching a WP multisite system. There won't be any community features or other interaction among sites. Each user's sites will be individual and stand alone.
With this in mind, we're debating three strategies:
1) ONE GIANT MULTISITE (set up a big, scalable installation and let it grow)
- Only updating one set up plugins, themes, etc.
- Only paying for one LiteSpeed license, etc.
- Complex, expensive setup (especially since it will take a while to build)
- All eggs in one basket...if one server goes down or gets hacked, all clients are affected
2) INDIVIDUAL SERVERS (individual servers, each hosting a set number of sites...when one server reaches the set resource level, we just add another server to the cluster).
- Not putting all eggs in one basket
- Modular approach
- Ability to offer clients a choice of different geographic server locations
- More maintenance required (although possibly offset by not having to maintain complex giant multisite)
- Paying for more LiteSpeed licenses, etc. (however we'll use large servers to minimize this)
- Need to update multiple servers when themes and plugins updated (not a terribly big deal)
3) MULTIPLE SERVER CLUSTERS (a few smaller clustered multisite setups, maybe spanning 3-4 servers each)
- Maintaining fewer systems than in strategy #2 (although managing this might be more complex overall)
- Paying for fewer LiteSpeed licenses, etc., than strategy #2
- Fairly complex, expensive setups
- Still putting all eggs in a few big baskets
Also, no matter what, it is always best to have the database(s) on a separate server, or is that only optimal after the installation reaches a certain size?
Any feedback would be appreciated!
