Linode upgrades are easier. The whole deal at Linode is more evolved. This is from Digital Ocean: FastResize is limited to the resources available on the physical hypervisor that your server is on. If there are no resources available, no sizes will be listed on the FastResize Page. (Linode automates all these steps...) If this is the case, you will need to take the slower method of snapshot & redeployment which is not limited to the same hypervisor: 1) create a snapshot of your server 2) delete your server to release the IP 3) immediately after the delete is finished, create a new droplet (choose the same datacentre) "select images" section switch to "my images" select your snapshot About to do this tonight, fingers crossed! Droplets look cheap but maybe they're competitive when you look at the number of cores. Seems to me a 4G Linode is faster than a 4G Droplet. But not 2x faster, IMO. A 4G Linode costs 2x the 4G Droplet. Digital Ocean feels like a better deal so far, but I need to upgrade to the 8G Droplet before I can really say for sure--the 4G Droplet isn't quite fast enough. As far as SSD, can your user tell the difference between a cache file that takes .001s vs .0001s? Probably not. For many of us, I think the more critical question is: How much does SSD improve MySQL performance?

  Good point. Cost of 4G Linode = 8G Droplet. I was more thinking 4G Linode to 4G Droplet comparison. Hypothetically, you run out of "buffer pool" and everything slows to a crawl. Maybe w/ SSD the swapping (or whatever MySQL does on disk) is less noticable. But in that comparison, maybe the 4G Linode CPU is a little faster so it might be a close contest. Granted I'm no MySQL guru and every application is different. BTW I have no affiliation with either company.

  Most database servers will use RAM as aggressively as possible (limits defined in the configuration files), so yes, more RAM is preferable. However, it's difficult to get a large amount of RAM at an affordable price when it comes to VPS. There's a little saying that's like, "Don't think of an SSD as expensive disk; think of it as cheap RAM." I think that's a good rule that serves well, more or less, if you orient your systems to behave that way.
