I need to host a cluster of around 2-3 Cassandra DB nodes along with an app server running Tomcat. I like DO but my worries are as follows:
The release version of KVM, at least as of a few months ago, didn't support TRIM on SSD; that, plus the fact that I don't know how others will use SSDs or if their file systems will keep the SSDs healthy, means that SSD performance on KVM is going to be highly unpredictable. I have not yet tested digital ocean, but I did test several other KVM+SSD shared-tenant hosting providers aggressively for Cassandra a couple months ago & they all failed badly.
Do you have something to say in this regard ?
