For a given cross-data-store transaction request at a storage service, a coordinator transmits respective voting transition requests to a plurality of log-based transaction managers (LTMs) configured for the respective data stores to which writes are directed in the transaction. The LTMs transmit responses to the coordinator based on data-store-specific conflict detection performed using contents of the voting transition requests and respective data-store-specific state transition logs. The coordinator determines a termination status of the cross-data-store transaction based on the LTMs' responses, and provides an indication of the termination status to the LTMs.

Log-based distributed transaction management

Methods and apparatus for private network peering in virtual network environments in which peerings between virtual client private networks on a provider network may be established by clients via an API to a peering service. The peering service and APImay allow clients to dynamically establish and manage virtual network transit centers on the provider network at which virtual ports may be established and configured, virtual peerings between private networks may be requested and, if accepted, established, and routing information for the peerings may be specified and exchanged. Once a virtual peering between client private networks is established, packets may be exchanged between the respective client private networks via the peering over the network substrate according to the overlay network technology used by the provider network, for example an encapsulation protocol technology.

Private network peering in virtual network environments

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.

Virtual network interface multiplexing

A traffic analyzer of a provider network identifies endpoint categories into which traffic directed to or from a first isolated virtual network of the provider network is to be classified. A first endpoint category includes an endpoint configured in a second isolated virtual network. Using packet-level metrics collected at virtualization management components of virtualization hosts, the traffic analyzer determines the amount of data transmitted between the first isolated virtual network and the various endpoint categories during selected time intervals. The traffic analyzer provides the categorized traffic amounts as input to a predictive model, and stores expected future traffic trends generated by the model.

The embodiments herein allow importation of a disk image (real or virtual) into a compute service environment. Any imported disk image can be reconfigured into a geometry compatible with the compute service environment into which it is imported. The reconfiguration can be accomplished through modifying the C, H, and S address values in the master boot record in order to match the virtualized disk environment.

Methods and apparatus for bandwidth metering in large-scale networks are disclosed. Metadata for a network transmission involving a virtualized resource at a host of a provider network, including endpoint address information and a traffic metric, is determined at a metering component. The metadata is aggregated at another metering component and provided to a traffic classification node. The traffic classification node generates a categorized usage record for the network transmission, based at least in part on network topology information associated with the provider network. The categorized usage record is used to determine a billing amount for the network transmission.

A fiber optic connection system includes a fiber optic switching device, a first optical fiber holder, and a second optical fiber holder. The fiber optic switching device includes optical waveguides and an optical waveguide carrier that carries the optical waveguides. The first optical fiber holder holds a first set of optical fibers at a first location relative to the optical waveguide carrier. A second optical fiber holder holds a second set of optical fibers at a second location relative to the optical waveguide carrier. The optical waveguide carrier is movable to position the one or more optical waveguides such that the optical waveguides optically couple the optical fibers in the first set of optical fibers to optical fibers in the second set of optical fibers.
