Managing failure behavior for computing nodes of provided computer networks

摘要

Techniques are described for providing managed computer networks. In some situations, the techniques include managing communications for computing nodes of a managed computer network by using one or more particular computing nodes of the managed computer network that are configured to operate as intermediate destinations to handle at least some communications that are sent by and/or directed to one or more other computing nodes of the managed computer network. In addition, the techniques may include managing the communications in accordance with configured failure behavior specified for one or more computing nodes of the computer network, such as specified failure behavior for a computing node configured to operate as an intermediate destination that indicates how communications that would otherwise be routed via the intermediate destination computing node are to be handled if the intermediate destination computing node fails or is otherwise unavailable (e.g., to block or allow such communications).

主权项

1. A computer-implemented method comprising:
receiving, by one or more configured computing systems, configuration information that specifies a failure behavior for a first computing node of a virtual computer network to identify how to handle communications if the first computing node fails; determining, by the one or more configured computing systems, that the first computing node is configured to act as an intermediate destination for a first communication, the determining being performed before sending the first communication over a substrate network on which the virtual computer network is overlaid; determining, by the one or more configured computing systems, that the first computing node has failed, and determining an alternative manner of handling the first communication based on the specified failure behavior for the first computing node; and initiating handling the first communication in the determined alternative manner.
