    Abstract: Techniques are described for managing customer-specified routing policies for network-accessible computing resources. In some situations, the customer-specified routing policies may be based at least in part on DNS (“Domain Name System”) information specified by a customer, such as if the customer specifies one or more target destinations to use with an indicated DNS domain name that are different from the destination IP address(es) provided for that DNS domain name by DNS servers—if so, the managing of such a DNS-based routing policy for that customer may include identifying when network-accessible computing resources provided to the customer send electronic communications to that DNS domain name, and causing those electronic communications to be redirected to the customer-specified target destination(s). Such customer-specified target destinations may include, in different situations, final destinations, intermediate destinations, etc., as well as identify particular routes.

    Abstract: Techniques for virtual network address space auto-migration are described. An existing network address space of a virtual network can be automatically migrated to a new network address space. The new network address space can be added to the virtual network, new subnets can be added to the new network address space that mirror existing subnets, and new compute instances can be added to the new subnets that mirror existing compute instances. Subsequent to the auto-migration, the virtual network can be connected with another network that has an address space that conflicted with the previous network address space of the virtual network but not the new network address space.

    Abstract: Techniques for defining and enforcing a set of rules that regulate network activity on a virtual network within a provider are described. An activity rule that regulates network activity on a virtual network within a provider network is received, the virtual network shared by a first customer of the provider network to allow other customers of the provider network to connect resource instances to the virtual network. Network activity data is received from a monitoring agent within the provider network, the network activity data relating to an activity of a first resource instance of a first other customer on the virtual network. The activity of the first resource instance is determined to violate the activity rule. The first resource instance is isolated from at least a portion of the virtual network.

    Abstract: Techniques for dynamic allocation of network address spaces in virtual networks implemented in a service provider system are described. Upon a scaling condition of an allocation rule being determined to be satisfied, a network address space of a virtual network can be automatically expanded or contracted. The scaling condition can be specified by a customer associated with the virtual network. The allocation rule may also include a allocation factor that indicates an amount of network addresses that are to be added to or removed from the virtual network.
