Patent attributes
A technology is described for providing a nondeterministic value to computing instances executing an application as part of a high availability system. An example method may include receiving a request for a nondeterministic value at a physical host that hosts a first computing instance, where the request may be for an application executing on the first computing instance. A nondeterministic value may be obtained from a nondeterministic value source located on the physical host and provided to the application executing on the first computing instance. A second request from a second computing instance may be received at the physical host, where the second request may be associated with a copy of the application executing on the second computing instance. The nondeterministic value may then be identified in the computer memory of the physical host and provided to the second computing instance over a computer network.
