A provider network implements service discovery and renaming. A provider network includes a domain name service (DNS) and a renaming tool. The DNS receives queries for service names and sends query logs to a data store. Each query log indicates the queried name and a network address (e.g., IP address). A user may request that the service be renamed to a new name. In response, the renaming tool adds a new entry to for the new name to the DNS. The renaming tool retrieves data from the query logs and identifies clients of the service. The renaming tool sends a notification to the identified clients that the name has changed to the new name. The renaming manger retrieves additional data from the query logs to identify how many of the clients have switched to using the new name. After enough clients have switched, the old name may be decommissioned.

Service discovery and renaming

Techniques are described for a Hypertext Transfer Protocol (HTTP) request monitoring application that provides an automated solution for managing cross-region compliance of incoming HTTP requests received by a web application or service. An HTTP request monitoring application comprises a plurality of modular components that can be readily integrated into a request processing pipeline of a web server or, more generally, into any application that processes HTTP requests. The components can include, for example, one or more analysis components, used to analyze various data elements contained in HTTP requests to estimate an origin requests, and one or more action components, used to perform various actions responsive to analysis components identifying potentially non-compliant requests (e.g., where such actions may include blocking the incoming requests, logging information about the requests, generating notifications, sending metrics to a monitoring service, etc.).

Network request intercepting framework for compliance monitoring

A scalable configuration management system manages distribution of data representing changes to configuration parameters in a network computing environment. The system uses a scalable pool of configuration management components to generate sequential update data for the configuration state of service providers, and distribute the sequential update data to service consumers. The service consumers can subscribe to and receive updates to the configuration state of service providers. In some embodiments, the system can provide snapshots of the complete current state of a service provider.

Streaming configuration management

Systems and methods are described for dynamically assigning data sets to cells within a cell-based architecture, in which individual cells individual cells operate independently of one another within the cell-based architecture. In response to a request to create a data set on the cell-based architecture, a system can dynamically assign the data set to a cell based on cell information, which can reflect cell health, utilization, configuration, and the like. The system can create a record that associates the data set to the selected cell, such that subsequent requests to access the data set can be routed to the selected cell based on the record. Dynamic assignment of data sets to cells improves on fixed assignment techniques, for example, by enabling heterogeneous cell configuration.

Cell-based distributed service architecture with dynamic cell assignment

Systems and methods are described to enable automation of service discovery records, such as domain name system (DNS) records, based on rules. An administrator of a hosted server, such as a virtual machine instance, may submit a rule to a rule-based DNS resolution system for generating DNS records to assist in discover of the hosted server. The rule may include criteria specifying servers to which the rule applies, as well as criteria for generating a domain name to associate with the server within a DNS record. The rule-based DNS resolution system can integrate with a hosting system providing the hosted server to obtain configuration information of the hosted server and generate DNS records in accordance with the rule. Rules may also be utilized to automate other aspects of the rule-based DNS resolution system, such as health checking and load balancing.

Rule-based automation of DNS service discovery

Systems and methods are described to enable integrating operation of a service record system with operation of an automatically scaled service hosting system. The service hosting system can maintain a set of servers to provide a network-accessible service, and the service record system can maintain records identifying the set of servers as endpoints for the service. The service hosting system can further modify the number of servers within the set based, for example, on demand. When the service hosting system intends to remove a server from the set, it may notify the service record system. The service record system, in turn, can determine whether any valid records are predicted to exist that identify the to-be-removed server as an endpoint for the service. If such records are predicted to exist, removal of the server can be delayed until those records expire, to prevent errors resulting from client reliance on those records.

Integration of service scaling and service discovery systems

Systems and methods are provided for determining engagement information related to client devices that have downloaded at least a portion of media content. In some embodiments, a server may receive a request for a playlist of media content from a client device. In response, the server may send a first portion of cookie to the client device. The server may receive a request for a fragment of media content with the first identifier value from the client device. In response, the server may determine that the request was received with the first identifier value and may increment a counter that represents a number of unique client devices that have downloaded at least a portion of the media content. The server may also send a second portion of the cookie to the client device that indicates that the client device has already downloaded at least part of the media content.

Using multiple cookies

Systems and methods are described to enable integrating operation of a service record system with operation of a hosting system. The service hosting system can maintain a set of servers to provide a network-accessible service, and the service record system can maintain records identifying the set of servers as endpoints for the service. The service record system can periodically transmit health check data to servers within the set, to verify their health status. When the service record system determines that a server is unhealthy, it can notify the hosting system. If the hosting system removes the server from the pool, it can notify the service record system, so that the service record system can halt further health checking of the server.

Integration of service scaling and external health checking systems

Systems and methods are provided for determining media engagement information related to client devices that do not support cookies. In some embodiments, a server may receive a request for a portion of live media content from a client device that does not support cookies. The server may identify a unique identifying characteristics associated with the media request. The server may determine a number of concurrent downloads of the live media content that are associated with the unique identifying characteristic. The server may further estimate a number of client devices associated with the unique identifying characteristic that have downloaded the live media content based on the number of concurrent downloads. In some embodiments, the server may also determine a number of computing devices that support cookie information and have downloaded the live media content to determine a total number of computing devices that have downloaded the live media content.
