Abstract: A constraint solver service of a computing resource service provider performs evaluations of logic problems provided by the service provider's users and/or services by deploying a plurality of constraint solvers to concurrently evaluate the logic problem. Each deployed solver has, or is configured with, different characteristics and/or capabilities than the other solvers; thus, the solvers can have varying execution times and ways of finding a solution. The service may control execution of the solvers using virtual computing resources, such as by installing and configuring a solver to execute in a software container instance. The service receives solver results and delivers them according to a solution strategy such as “first received” to reduce latency or “check for agreement” to validate the solution. An interface allows the provider of the logic problem to select and configure solvers, issue commands and modifications during solver execution, select the solution strategy, and receive the solution.

Abstract: Security policies may be utilized to grant or deny permissions related to the access of computing resources. Two or more security policies may be compared to determine whether the policies are equivalent, whether one security is more permissive than another, and more. In some cases, it may be possible to identify whether there exists a security permission that is sufficient to determine two security policies lack equivalency. Propositional logics may be utilized in the evaluation of security policies.

Abstract: A virtual network verification service for provider networks that leverages a declarative logic programming language to allow clients to pose queries about their virtual networks as constraint problems; the queries may be resolved using a constraint solver engine. Semantics and logic for networking primitives of virtual networks in the provider network environment may be encoded as a set of rules according to the logic programming language; networking security standards and/or client-defined rules may also be encoded in the rules. A description of a virtual network may be obtained and encoded. A constraint problem expressed by a query may then be resolved for the encoded description according to the encoded rules using the constraint solver engine; the results may be provided to the client.

Abstract: Methods, systems, and computer-readable media for automated packetless network reachability analysis are disclosed. An analysis is performed of network configuration data for a network comprising a host computer. Based at least in part on the analysis, one or more ports at the host computer that are reachable from another computer are determined. Based at least in part on the analysis, one or more routes to the one or more ports are determined. A report is generated that is descriptive of the one or more ports and the one or more routes.
