Abstract: Systems and methods are provided for enforcing symmetric flows of cross-region network traffic through firewalls in multi-region network environments. Enforcement may be configured automatically by analyzing network policy data to identify cross-region traffic that is to be firewalled, and configuring gateway nodes in the various regions to implement symmetric bidirectional flows through any firewalls in the communication path. Beneficially, by enforcing symmetric bi-directional flows of traffic through any firewalls in a communication path, the firewalls may maintain the state of a given communication session even when the communication session is between endpoints in different regions that have different architectures.

Abstract: Connectivity is enabled between a first and second isolated network using a virtual traffic hub that includes a decision master node responsible for determining a routing action for a packet received at the hub. At the hub, a determination is made that a particular domain name system (DNS) message being directed to a first resource in the first isolated network is to include an indication of a second resource in the second isolated network. The second resource is assigned a network address within a private address range of the second isolated network, which overlaps with a private address range being used in the first isolated network. The hub causes a transformed version of the network address to be included in the DNS message delivered to the first resource.

Abstract: Systems and methods are provided for evaluation of networks and changes thereto using automated analysis of network models. The automated analysis can be used to determine how to implement and mutate networks efficiently and effectively, to determine whether and why network resources are unable to communicate with each other, and the like. Automated analysis can allow users (e.g., network administrators) to define networks and pose changes to networks using high-level policies (e.g., written in a declarative language), have those polices automatically translated to lower-level implementation operations for analysis, and in some cases have results of the analysis presented back to the users in an easy-to-understand form.

Abstract: Metadata indicating that a virtual traffic hub enabling connectivity between a plurality of isolated networks has been established is stored. A determination is made that a first entry of a first isolated network attached to the hub is to be represented in a second routing table of a second isolated network attached to the hub, e.g., to enable network packets originating at resources of the second isolated network to be transmitted via the hub to the first isolated network. A new entry corresponding to the first entry is included in the second routing table.

Abstract: A pair of virtual routers is configured. In response to programmatic requests, dynamic transfer of routing information between the routers in accordance with configuration settings indicated by a client is enabled. The routing information is associated with a set of isolated networks to which the virtual routers are attached. A network packet originating at an address in a first isolated network is transmitted to an address in a second isolated network using a route determined from routing information transmitted between the virtual routers according to the configuration settings.

Abstract: This disclosure describes techniques for configuring and managing scalable global private networks associated with a service provider. Different input mechanisms, such as an API, a UI, or a CLI may be utilized to configure, and manage a global private network that spans across the cloud in different geographic locations and connects to different stand-alone networks. The user may proactively use the input mechanisms to configure and query different network resources to reactively configure settings for reacting to one or more events. The input mechanisms may also be utilized to define the network resources to be modeled within the global private network as well as connections within the global network. A user may configure events/metrics to be monitored, tasks/workflows to be performed, and the like. In some configurations, a network management service (NMS) may perform health monitoring and reachability monitoring to identify possible issues in the global network.

Abstract: Systems and methods are provided for management of network segments that cross geographic regions and/or other types of network divisions in a cloud-based network environment. Gateway may manage traffic across regions using routing metadata that includes a segment identifier. The gateways may also signal their routes across regions based on segment data, and implement the signaled routes using segment-based routing policies. Route selection may be performed using optimization data.

Abstract: At an action implementation layer of a virtual traffic hub, a packet is obtained from a first isolated network. A first action, generated at a decision making layer of the hub based on a first route table of the hub, is performed, resulting in transmission of at least one network packet to a first destination. In response to a second packet, obtained at the action implementation layer from a source outside the first isolated network, a second action is performed, resulting in transmission of at least one packet to a second destination. The second action is generated based on a second route table of the hub.

Abstract: An isolated packet processing cell of a packet processing service, comprising an action implementation node and a decision master node, is assigned to an application. An indication of processing rules of the application is transmitted to the decision master node. In response to receiving a particular packet, the action implementation node obtains a representation of an action (which is based on the processing rules) from the decision master node and executes the action.

Abstract: Systems and methods are provided for obtaining policy data associated with a private network implemented at least partly within a cloud provider network; establishing, based on the policy data, a first segment within the private network, wherein in a first geographic region of the cloud provider network, traffic associated with the first segment is isolated from traffic associated with a second segment of the private network, and wherein in a second geographic region of the cloud provider network, traffic associated with the first segment is isolated from traffic associated with a third segment of the private network; obtaining metadata indicating an isolated network of the cloud provider network is associated with the first segment; and enabling the isolated network to communicate, over the first segment, across the first geographic region and the second geographic region.
