Abstract: A control-plane component of a virtual network interface (VNI) multiplexing service assigns one or more VNIs as members of a first interface group. A first VNI of the interface group is attached to a first compute instance. Network traffic directed to a particular endpoint address associated with the first interface group is to be distributed among members of the first interface group by client-side components of the service. The control-plane component propagates membership metadata of the first interface group to the client-side components. In response to a detection of an unhealthy state of the first compute instance, the first VNI is attached to a different compute instance by the control-plane component.

Abstract: Techniques are described for managing communications for a managed virtual computer network overlaid on a distinct substrate computer network, including for communications between computing nodes of the managed virtual computer network connected to the substrate network and other network nodes external to the substrate network. The managed virtual computer network may have multiple associated virtual network addresses, with each of the computing nodes being associated with at least one of the virtual network addresses, and with one or more external network nodes being integrated into the managed virtual computer network based at least in part by associating one or more other of the virtual network addresses with the external network nodes. The managing of the communications may further include using one or more translation manager modules that interconnect the substrate network with one or more external networks or other external connections via which the external network nodes are accessible.

Abstract: A control-plane component of a virtualization-based packet processing service determines (a) a performance goal for a first category of packet processing operations to be implemented using compute instances of a virtual computing service and (b) one or more packet processing rules. The control-plane component assigns one or more compute instances as nodes of a packet processing cluster designated to perform the requested operations. The control-plane component provides metadata to the client, to be used to establish connectivity between the cluster and one or more sources of the traffic whose packets are to be processed.

Abstract: A request to obtain network health information pertaining to a client account of a provider network is received via a programmatic interface. Respective sets of network metrics are obtained from several data sources of the provider network, and a respective network health state descriptor is generated for one or more resource sets associated with the client account. A response to the request is prepared using the network health state descriptor and transmitted.

Abstract: Respective network metrics sets corresponding to one or more data sources are examined at a network health manager. Network health states corresponding to one or more endpoint pair categories are determined based on the analysis of the network metric sets. An indication of the network health state of a particular endpoint pair category is stored.

Abstract: A determination is made that a graphical representation of network health state information pertaining to a client account of a provider network is to be provided. Using respective network metrics groups corresponding to several data sources, a network health state descriptor corresponding to a resource associated with the client account is generated. A data set usable to generate a graphical display of network health state information of the resource of the client account is transmitted.

Abstract: An occurrence of a network health impairment event associated with a service of a provider network is detected using metrics corresponding to one or more data sources. Based on an analysis of a list of services being utilized on behalf of a customer, a determination is made that the probability of a negative impact of the impairment on an application of the customer is below a threshold. A network health state message indicating a healthy state of resources allocated to the customer is transmitted to a destination associated with the first customer.

Abstract: Methods and apparatus that allow clients to connect resource instances to virtual networks in provider network environments via private IP. Via private IP linking methods and apparatus, a client of a provider network can establish private IP communications between the client's resource instances on the provider network and the client's resource instances provisioned in the client's virtual network via links from the private IP address space of the virtual network to the private IP address space of the provider network. The provider network client resource instances remain part of the client's provider network implementation and may thus also communicate with other resource instances on the provider network and/or with entities on external networks via public IP while communicating with the virtual network resource instances via private IP.

In some situations, the emulating of networking device functionality includes receiving routing communications directed to the networking devices and using included routing information to update the configured network topology for the managed computer network.

Abstract: Various systems and processes may be used to manage Internet Protocol (IP) addresses that are dynamically assigned. In particular implementations, systems and processes for managing IP addresses that are dynamically assigned may include the ability to determine whether an identifier for a web service has been received from a customer having one or more virtual machines in a service provider network, the web service being accessible by the customer's virtual machines over an external communication network. The systems and processes may also include the ability to determine a number of IP addresses for the web service, identify virtual machines of the customer that are allowed to communicate with the web service, generate one or more IP address lists for the identified virtual machines, and update security tables for the identified virtual machines with the IP address lists at server computers hosting the identified virtual machines.

Abstract: In accordance with a designation of a private alias endpoint as a routing target for traffic directed to a service from within an isolated virtual network of a provider network, a tunneling intermediary receives a baseline packet generated at a compute instance. The baseline packet indicates a public IP (Internet Protocol) address of the service as the destination, and a private IP address of the compute instance as the source. In accordance with a tunneling protocol, the tunneling intermediary generates an encapsulation packet comprising at least a portion of the baseline packet and a header indicating the isolated virtual network. The encapsulation packet is transmitted to a node of the service.

Abstract: Techniques are described for providing load balancing functionality among multiple computing nodes. In some situations, the provided load balancing functionality includes dynamically scaling a group of multiple computing nodes for which the load balancing is performed, such as to dynamically expand and/or shrink the quantity of computing nodes in the group based on predefined criteria. At least some of the computing nodes of a group may be part of one or more physical computer networks in one or more geographical locations under control of a user or other entity, and at least some of the dynamic scaling of the group may use one or more other computing nodes that are part of a remote computer network (e.g., a virtual computer network provided under the control of a network-accessible service). The defined criteria used for the dynamic scaling may be determined in various manners and based on various factors.

Abstract: Computing resource service providers may provide computing resources to customers in a multi-tenant environment. These computing resources may be behind a firewall or other security device such that certain information does not reach the computing resources provided to the customer. A logging entity may be implemented on computer server operated by the computing resource service provider. The logging entity may obtain log information from the firewall or other security device and store the log information such that it is accessible to the customer. Additionally, the log information may be provided to other services such as a metrics service or intrusion detection service.

Abstract: A request to establish a VPN connection between a customer data center and a set of resources of a provider network is received. A new isolated virtual network (IVN) is established to implement a virtual private gateway to be used for the connection. One or more protocol processing engines (PPEs) are instantiated within the IVN, and a respective VPN tunnel is configured between each of the PPEs and the customer data center. Routing information pertaining to the set of resources is provided to the customer data center via at least one of the VPN tunnels, enabling routing of customer data to the set of resources within the provider network from the customer data center.

Abstract: 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. For example, a manager module associated with a source computing node may select one or more particular intermediate destination computing nodes to use for one or more particular communications from the source computing node to an indicated final destination, such as based on a configured logical network topology for the managed computer network. The manager module then forwards those communications to a first of the selected intermediate destination computing nodes for further handling.
