Abstract: Techniques are described for managing communications between multiple intercommunicating computing nodes, such as multiple virtual machine nodes hosted on one or more physical computing machines or systems. In some situations, users may specify groups of computing nodes and optionally associated access policies for use in the managing of the communications for those groups, such as by specifying which source nodes are allowed to transmit data to particular destinations nodes. In addition, determinations of whether initiated data transmissions from source nodes to destination nodes are authorized may be dynamically negotiated for and recorded for later use in automatically authorizing future such data transmissions without negotiation. This abstract is provided to comply with rules requiring an abstract, and it is submitted with the intention that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: Techniques are described for managing the execution of programs on multiple computing systems, such as on virtual machine nodes executing on the computing systems. A program execution service may in some situations provide the multiple computing systems and manage the program execution on behalf of multiple customers or other users, including to select appropriate computing systems to execute one or more instances of a program for a user, such as based in part on configuration information specified by the user. The described techniques may further include managing communications between multiple intercommunicating computing nodes in some situations.

Abstract: Techniques are described for managing the execution of programs on multiple computing systems, such as computing systems organized into multiple groups. A program execution service manages the program execution on behalf of multiple customers or other users, and selects appropriate computing systems to execute one or more instances of program, such as based in part on locations of one or more previously stored copies of the program from which copies of the program to execute may be acquired. For example, in some situations the selection of an appropriate computing system to execute an instance of a program is based in part on physical or logical proximity to other resources, such as stored copies of the program, executing copies of the program, and/or available computing systems.
