Failure is inevitable. Disks fail. Software bugs lay dormant waiting for just the right conditions to bite. People make mistakes. Data centers are built on farms of unreliable commodity hardware. If you are running in a cloud environment, then many of these factors are outside of your control. To compound the problem, failure is not predictable and does not occur with uniform probability and frequency. The lack of a uniform frequency increases uncertainty and risk in the system. In the face of such inevitable and unpredictable failure, how can you build a reliable service that provides the high level of availability your users can depend on? A naive approach could attempt to prove the correctness of a system through rigorous analysis. It could model all different types of failures and deduce the proper workings of the system through a simulation or another theoretical framework that emulates or analyzes the real operating environment. © 2013 ACM.

One embodiment of the present invention sets forth a technique for adapting playback bit rate to available delivery bandwidth in a content delivery system comprising a content server and a content player. A content player periodically estimates whether a given playback bit rate can feasibly provide complete playback for a given title assuming currently available bandwidth. If playback becomes unfeasible at a current bit rate assuming currently available bandwidth, then the content player adapts the bit rate downward until a feasible bit rate is achieved. If playback is feasible using a higher bit rate, then the content player may adapt the bit rate upward.

One embodiment of the present invention sets forth a technique for streaming digital media content with transition effects. Audio data may be modulated and received by the streaming device for an audio fade-in effect. Similarly, video data may be modulated to perform various visual effects. Such a technique allows for fading-in of audio and/or video, fading-out of audio and/or video, and effects that blend audio from different content and video from different content during a transition from one digital media content to a different digital media content or within the same digital media content. The modulated audio and video data to generate the audio or video effect during a transition may be precomputed or computed in real-time and transmitted to the streaming device. The streaming device switches between original unmodulated content streams and effect content streams when transitions are detected.

One embodiment of the present invention sets forth a technique for providing a variation of digital content that is based on a client-specified context token. Localized digital assets, e.g., graphics resources, video resource, audio resources, and text string resources, are stored as a collection of records and are dynamically linked to a assemble a software system based on the client-specified context token to generate the variation of digital content. The client receives the assembled variation of the digital content including the localized digital assets specified by the client-provided context.

A security application manages security and reliability of networked applications executing collection of interacting computing elements within a distributed computing architecture. The security application monitors various classes of resources utilized by the collection of nodes within the distributed computing architecture and determine whether utilization of a class of resources is approaching a pre-determined maximum limit. The security application performs a vulnerability scan of a networked application to determine whether the networked application is prone to a risk of intentional or inadvertent breach by an external application. The security application scans a distributed computing architecture for the existence of access control lists (ACLs), and stores ACL configurations and configuration changes in a database. The security application scans a distributed computing architecture for the existence of security certificates, places newly discovered security certificates in a database, and deletes outdated security certificates. Advantageously, security and reliability are improved in a distributed computing architecture.
