摘要： Several different embodiments of a massively scalable object storage system are described. The object storage system is particularly useful for storage in a cloud computing installation whereby shared servers provide resources, software, and data to computers and other devices on demand. In several embodiments, the object storage system includes a ring implementation used to associate object storage commands with particular physical servers such that certain guarantees of consistency, availability, and performance can be met. In other embodiments, the object storage system includes a synchronization protocol used to order operations across a distributed system. In a third set of embodiments, the object storage system includes a metadata management system. In a fourth set of embodiments, the object storage system uses a structured information synchronization system. Features from each set of embodiments can be used to improve the performance and scalability of a cloud computing object storage system.

摘要： Embodiments are directed towards overprovisioning IP addresses among a plurality of traffic management devices (TMDs). A plurality of IP addresses may be distributed among a plurality of available TMDs. A corresponding mirror TMD may be determined for each IP address. The corresponding mirror TMD for an IP address may be different than the available TMD currently associated with the IP address. In various embodiments, connections associated with each IP address may be mirrored at their corresponding mirror TMDs. The available TMDs may be employed to perform traffic management tasks on received packets based on at least a destination IP address of the received packets and the IP addresses associated with the available TMDs. If a TMD becomes unavailable, the IP addresses associated with the unavailable TMD may be redistributed to at least one remaining available TMD.

摘要： A graphics client receives a frame, the frame comprising scene model data. A server load balancing factor is set based on the scene model data. A prospective rendering factor is set based on the scene model data. The frame is partitioned into a plurality of server bands based on the server load balancing factor and the prospective rendering factor. The server bands are distributed to a plurality of compute servers. Processed server bands are received from the compute servers. A processed frame is assembled based on the received processed server bands. The processed frame is transmitted for display to a user as an image.

摘要： Some embodiments provide a proprietary 64-bit consistent distribution scheme that preserves the efficiencies of CARP while providing a significantly more balanced distribution of requests that is on par with schemes reliant on computationally expensive cryptographic hashes. The scheme performs hashing of requested URLs and identifiers of available servers over a 64-bit space while optimizing the hashing to remove computationally expensive operations. Some embodiments provide a variant of the scheme to provide a differentiated distribution on the basis of one or more differentiating factors. A first variant utilizes load factor values to adjust the resulting hashes and to produce a first distribution of differentiated content that varies from a second distribution of undifferentiated content. A second variant identifies requests for differentiated content from requests for undifferentiated content and utilizes a first scheme to distribute the differentiated content and a second altered scheme to distribute the undifferentiated content.
摘要翻译：一些实施例提供专有的64位一致分配方案，其保持CARP的效率，同时提供与依赖于计算上昂贵的加密散列的方案相当的请求的显着更平衡的分配。该方案在64位空间内执行所请求的URL和可用服务器标识符的哈希，同时优化散列以消除计算上昂贵的操作。一些实施例提供了一种基于一个或多个微分因素来提供差分分布的方案的变型。第一变体使用负载因子值来调整所得到的散列并产生从未分化内容的第二分布变化的差异化内容的第一分布。第二变体识别针对未分化内容的请求的差分内容的请求，并且利用第一方案来分发差异化内容，以及第二改变方案来分发未分化内容。

摘要： Systems and methods utilize a distributed server network to allow for the optimization of the upload of a data stream from a computing device. Performance metrics are estimated for different network paths from the computing device to a variety of entry servers in the distributed server network. Based on the estimated performance metrics, one or more entry servers are then selected to receive the data stream from the computing device. As a result, the systems and methods described herein allow for high quality upload performance which addresses the first mile vulnerability issues of the data stream. The distributed server network can then transmit copies of the data stream in real-time to other computing devices.

摘要： A method, system and computer program product for managing pattern contents across multiple racks. The workload usage characteristics of the pattern contents on a primary rack in a domain of racks are collected based on monitoring the workload usage of the pattern contents in the pattern definition and in the deployed pattern. Furthermore, information regarding use of the pattern definition, the deployed pattern and the pattern contents by users (“human interaction usage patterns”) is collected based on monitoring the human interaction usage patterns. The pattern contents are then ranked based on analyzing the collected workload usage characteristics and analyzing the collected information regarding human interaction usage patterns. Once the pattern contents are ranked, those contents that are highly ranked are deemed to be more likely to be utilized in the pattern and therefore are the contents that are copied from the primary rack to the other racks of the domain.

摘要： A system, method and computer-readable medium for request routing based on content popularity information are provided. A client computing device transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of popularity information pertaining to the requested resource. The client computing device then transmits a second DNS query to the content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat until a DNS nameserver resolves a DNS query from the client computing device.

摘要： A cloud-based email system is accessed by way of a cloud access security system. The cloud access security system allows for encryption of incoming emails and outgoing emails stored in the cloud-based email system. The cloud access security system includes a protocol proxy for providing an interface between a client computer of a user and the cloud-based email system, an encryption module for indexing and encrypting emails, and an event listener for receiving email event notifications from the cloud-based email system and replacing emails with corresponding encrypted emails. The cloud access security system may receive encryption keys from a key manager hosted by a key server, which may be part of the cloud access security system or hosted on premise in the same private computer network as client computers employed by users.
