This disclosure describes techniques for distributed storage of files that represent video content across different storage tiers to reduce the amount of computing resources used to store the files, while maintaining a low latency when responding to user requests to stream the video content. Video streaming services support the streaming of video content at different resolutions to support various user devices and/or user preferences. To provide streaming of a particular video content item at different resolutions, the video streaming services may store multiple files that represent the video content item for the different resolutions and stream at different bitrates to user devices. The techniques described herein include storing files configured to stream a video content item at different bitrates (and for different display resolutions) in a tiered storage structure to reduce the amount of computing resources taken to store the files.

Distributed storage of files for video content

Techniques for managing encoder configuration based on content delivery network performance are described. A computer-implemented method may include obtaining availability metrics from one or more content delivery networks (CDNs), the availability metrics associated with one or more content streams provided by the one or more CDNs, determining at least one CDN has less than a threshold capacity based at least on the availability metrics, and sending a request to one or more encoders associated with the one or more content streams to reduce a quality of at least one of the one or more content streams based at least on the availability metrics.

Managing encoder configuration based on content delivery network performance

Disclosed are various embodiments for detecting malicious activity through the use of inert input parameters to a web service or web page. A service request is received from a client computing device via a service endpoint. A modification is detected to an expected parameter in the service request. The expected parameter is configured to be inert in effect with respect to the service when the expected parameter has not been modified. One or more actions are initiated in response to the modification.

Inert parameters for detection of malicious activity

This disclosure relates to a geographically distributed, multi-master system for storing data records, and associated methods and computer-readable media for replicating data records across geographically distributed data stores of the system in a manner that achieves consistency between data stored in geographically distributed regions as well as deterministic data replication.
