Abstract: Disclosed are various embodiments that provide multipath connectivity between edge locations and regions in a cloud provider network. In one embodiment, data is received at a provider substrate extension of a cloud provider network, where the data is to be transmitted to a destination in a data center of the cloud provider network. The provider substrate extension is at an edge location of the cloud provider network. The data is transmitted to a destination in the data center of the cloud provider network via a plurality of communication links from the edge location to the data center.

Abstract: One variation of a system includes a hub and a module coupled to a solar array. During a first time period: the hub detects nominal operation of the solar array broadcasts a first token accordingly; and the module receives the first token, authenticates the first token; and maintains a switch—coupled to an output terminal of the module—in a closed position to output power from a solar panel to an inverter in response to authentication of the first token. During a second time period: the hub detects deviation of the solar array from nominal operation and withholds broadcast of tokens accordingly; and the module triggers the switch to transition to an open position to cease output of power from the first solar panel to the inverter in response to absence of receipt of a second token broadcast by the hub.

Abstract: A networking manager of an extension server of a virtualized computing service detects that a data link layer frame has been obtained at the extension server. The networking manager delivers at least a portion of contents of the frame to a compute instance running at the extension server in response to determining that a destination media access control (MAC) address of the frame matches a MAC address of a local-premise-access virtual network interface attached to the compute instance. The local-premise-access virtual network interface is not assigned an Internet Protocol (IP) address from a range of IP addresses managed by the virtualized computing service.
