Building a smart engine for multi-cloud, highly available IaaS
Grazed from CloudNod. Author: Scott Sanchez.
I’ve been having a conversation on twitter with @reillyusa this morning about how a “cloud of clouds” could help prevent a single point of failure like we saw take down so many sites yesterday due to issues at AWS. One availability zone or region goes down at AWS? No problem, as service levels started to degrade your apps/data/state/etc was moved to another zone or to Rackspace or someone else. The engine would reduce the cost of having HA because it would make smart decisions about where, how and why to move workloads, and could even have a bunch of hot/warm instances running that are transparently shared across users to reduce the cost of having your own ‘dedicated’ instances at other clouds waiting for you to fail…
