Take for example master/slave replication: 1) It doesn't scale writes (at all). 2) It relies on you having complete duplication of contents on all nodes - so a replication slave with a large working set won't work. Since I wrote this article the maximum memory/node has moved up to 68.4 GB, but it will cost you $2.40/hour ($1700/month). I can buy a Dell R900 in only a few months at that rate ;) Earl – it may be possible, but the effort for MySQL to get to that point is *massive*. Take for example master/slave replication:

Given a master/slave configuration, it should be possible to spin up new slave instances fairly easily. Take a snapshot of an existing slave volume, fire up a new MySQL instance with a volume created from that snapshot, point it at the master, and it should be ready for action in very short order. Stick a smart proxy in front of your MySQL cluster, and it can point queries at whatever slave instance is least busy (or just round-robin it). When demand drops below a certain threshold, just terminate one of the slave instances. Am I missing something? Earl Why do you say that, Morgan?

Most cloud offerings out there with all the benefits of cloud are shared. While that may not mean much it gets into the topics of compliance, security and performance. The alternative is 'private cloud' and what exactly is the difference. My company specializes in private cloud solutions. We approach hosting a bit differently. We don't have package solutions but rather we like to get into your shoes find out how things work, what your doing and develop a HA solution from scratch. Take a look at a article regarding our 'private cloud' from eWEEK http://www.eweek.com/c/a/Cloud-Computing/Logicworks-Offers-Private-Cloud-Service-586768/ In addition since i want to stay on topic for MySQL http://www.logicworks.net/news/2008/logicworks-becomes-first-authorized-mysql-platinum-hosting-partner-us I'm interested in making connections, finding out what people are doing out there with their technology solutions.

Their main US DC is 'DFW' dallas fort worth which is where mailtrust is at and where all new managed configurations in the US are being popped. That said, I know by default all managed hosting customers only get 100Mb/s swithces unless you pay the gE premium though again this is something that may have changed since I left. - Trent @Morgan
