Abstract: Techniques for API-based endpoint discovery and centralized load balancing involving provider substrate extension resources are described. A discovery coordinator service located within a provider network can identify one or more endpoints from a set of potentially distributed endpoints for a client to utilize, where endpoints may be located within provider substrate extensions of the provider network. The discovery coordinator service can analyze the loads of these endpoints, via client lease information, to identify nearby, low-load resources that may be most optimal for the client to use via providing minimal latency of access.

Abstract: A representation of a category of task offloaders is stored, in response to receiving a descriptor of the category, in a database of categories of offloaders which can be attached to servers of one or more classes. An indication of server configurations which include a task offloader of the category is provided via programmatic interfaces. A task is executed at a task offloader of a server with one of the server configurations.

Abstract: Connectivity between a radio-based application pipeline processing server and a control plane of a provider network is verified. Based on requests received at the control plane, a first isolated request handler, a second isolated request handler and an offloading manager are launched at the server. The offloading manager causes a first network function for which a request is received from the first request handler to be executed at a first network function accelerator of the server, and a second network function for which a request is received from the second request handler to be executed at a second network function accelerator of the server.

Abstract: A first analysis based on at least a subset of collected health metrics of a monitored resource is performed at a health monitoring service. If the first analysis indicates that the probability that the monitored resource is in an unhealthy state is above a threshold, a mitigation action that includes directing at least some of the workload away from the monitored resource is implemented. In addition, a remediation analysis of the monitored resource is started to determine, using at least one additional health metric that was not examined in the first analysis, whether a longer-term remediation action is to be initiated.

Abstract: Techniques are described for enabling users of a service provider network to create and configure “application profiles” that include parameters related to execution of user workloads at provider substrate extensions. Once an application profile is created, users can request the deployment of user workloads to provider substrate extensions by requesting instance launches based on a defined application profile. The service provider network can then automate the launch and placement of the user's workload at one or more provider substrate extensions using edge-optimized compute instances (e.g., compute instances tailored for execution within provider substrate extension environments).

Abstract: Techniques for utilizing dual-stack network addressing for compute instances hosted in an edge location of a cloud provider network along with communications service provider (CSP) network addresses are described. A first network address is assigned to the compute instance from a pool of network addresses of the cloud provider network, and a second network address is associated with the compute instance that is provided by the CSP network. A gateway of the edge location is updated to direct packets addressed to the second network address to the compute instance via use of the first network address.

A schedule is generated for use of one or more of the plurality of frequency schemes in the geographic area by the radio-based network based at least in part on whether the respective quality-of-service requirements are capable of being met by the individual ones of the plurality of frequency schemes.

Abstract: A first virtualization control mode to be used for configuring one or more compute instances is determined. Based at least partly on the mode, preparatory configuration operations for launching a compute instance are initiated. The operations include transferring at least a portion of a machine image to a storage device accessible from a host, and initialization of a virtual network interface. A compute instance is instantiated using the machine image at the host. The compute instance is a thread of an intermediary process launched by an administrative agent at the host in response to a launch request.

Abstract: Techniques are described for a cloud provider to provide a managed experience related to the use of virtual networks and subnets to logically group user computing resources deployed at provider substrate extensions. A cloud provider enables users to create virtual network templates used when deploying computing resources at provider substrate extensions, where such virtual network templates may include various networking, security, and other configurations to be applied to network traffic and other activity of resources deployed within an associated virtual network. Once a virtual network template is defined, a user can use the template as the basis to launch resources into the virtual network and, by extension, into provider substrate extensions associated with the virtual network. Upon receiving such a request, the provider network can manage the creation and configuration of underlying subnets, route tables, and other resource, as needed, at each of the relevant provider substrate extensions.

Abstract: 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.
