Abstract: This invention discloses a method and apparatus for protecting message sender identity in an instant messaging system. Upon receiving an instant message via the instant messaging system, the system may withhold the identity of the sender while pushing the message to the other users in the communication channel. Identity withholding is controlled by the sender on his or her device. The disassociated message is displayed in a style that is common to users, for example, displaying in the middle, displaying in a common location, or even displaying in random locations on a screen of the message thread. Although someone can take a screenshot of a message, the screenshot does not contain any information that can be used to identify the actual sender of the message. In this case, users may generally rely on the context to appreciate the dynamics and/or flow of the conversation. The invention thus enables information sharing in an instant messaging system without the concern of screenshot.

Abstract: In various implementations, methods and systems resource balancing in a distributed computing environment are provided. A client defined resource metric is received that represents a resource of nodes of the cloud computing platform. A placement plan for job instances of service applications is generated. The placement plan includes one or more movements that are executable to achieve a target placement of the job instances on the nodes. It is determined that the placement plan complies with placement rules. Each placement rule dictates whether a given job instance of the job instances is suitable for placement on a given node of the nodes. The placement plan is executed based on determining that the target placement of the job instances improves balance of resources across the nodes of the cloud computing platform based on the resource represented by the client defined resource metric.

Abstract: Network traffic data associated with data requests to computer applications based on static policies is collected. An optimization order is established among network parameters. A first network parameter of a higher rank in the optimization order is estimated based on the collected network traffic data before one or more other network parameters of lower ranks are estimated. Optimal values for the other network parameters are estimated based at least in part on the estimated first optimal value for the first network parameter. The estimated first optimal value of the first network parameter and the estimated optimal values for the other network parameters are propagated to be used by user devices to make new data requests to the computer applications.

Abstract: A server computer sets a priority order of each of contents based on an attribute of each of the contents designated by HTML data and provides the HTML data including the priority order with a client computer. The client computer acquires the contents from the server computer by using streams with priorities depending on the priority order of each of the contents designated by the HTML data provided from the server computer. The client computer controls display using a part of the contents and caches other contents from among the acquired contents.

Abstract: A method for providing seamless redundancy in an output data stream includes the steps of: receiving a first data stream originating from a first location, the first data stream being conveyed over a first network path; receiving at least a second data stream originating from a second location that is geographically distinct from the first location, the second data stream comprising nominally identical content relative to the first data stream, the second data stream being conveyed over a second network path that is topologically distinct from the first network path; and combining first data segments from the first data stream and second data segments from the second data stream to generate a single, uninterrupted output data stream having a reduced likelihood of overlapping, missing and/or corrupt data segments.

Abstract: Data can be communicated across a clustered data processing environment. A server can receive a request and a token from a web user interface component and search for the data object associated with the token in a local cache. If the data object is found, it can be used to communicate with a backend server, in order to receive a response with server-specific data. The response and the data object can be sent back to the web user interface.

Abstract: Embodiments presented herein provide a multi-region search service to customers of a cloud computing service provider. The search service allows cloud based computing resources deployed across multiple services and across multiple regions in which services are deployed to be rapidly identified. Search queries (such as simple free text or structured conditions) are evaluated across all of the cloud based services in all regions hosted by a service provider to identify a set of computing resources instantiated (or otherwise controlled) by a common account owner. To maintain the search index, the search service may include an event poller which deduplicates change events written to a staging database. In turn, an index writer performs batch updates to partitions of the search index using records pulled from the staging database.

Abstract: According to embodiments of the present invention, machines, systems, computer-implemented methods and computer program products for mimicking a presence notification to optimize utilization of computing resources of a system comprising a plurality of virtual components and a virtual component manager are provided. Using the virtual component manager, one or more components that are each performing functions limited to providing a presence notification may be detected. The detected one or more components may be suspended, and the presence notifications for each suspended component may be generated and transmitted by the virtual component manager. Suspending a component that is solely providing a presence notification frees up resources that may be utilized for another component performing computational work.

Abstract: A distributed system may implement optimizing for infrastructure diversity in resource placement. A placement request for a resource to be placed at one of multiple resource hosts respectively implemented at infrastructure units may be received. An evaluation of utilization data for the multiple resource hosts may be performed with regard to an infrastructure diversity constraint for placing resources at the infrastructure units. A selection of a resource host may be made based on the evaluation of the utilization data according to the infrastructure diversity constraint. In some embodiments to select the resource host, the effect of placing the resource on candidate resource hosts on an infrastructure-diverse capacity metric may be determined to score the candidate resource hosts. The resource may be placed at the selected resource host.

Abstract: A method, apparatus and computer-readable storage medium distribute a non-live content stream in a network. An initial meta-file is transmitted in response to a request for the content, which identifies a division of the content stream into blocks, and available sources for delivery of the blocks. The initial meta-file can identify a first multicast and a second multicast server, assigning a first and second portion of the blocks for delivery using the first and second multicast source server, respectively. The first and second portions are transmitted using the first and second multicast source servers, respectively. The first and second portions correspond to distinct non-overlapping portions of the non-live content stream. The initial meta-file can also identify a unicast source server, assigning a third portion of the blocks for delivery using the unicast source server, the third portion being transmitted by the unicast source server.

Abstract: A system and method for profile-based cache management is disclosed. A cache management service can obtain a plurality of requests for network resource and corresponding responses, group the requests based, at least in part, on various criterion or technique, determine and cache content parts of the responses corresponding to each group of requests. Cache profiles corresponding to each group of requests and identifying corresponding cached content parts can be built, maintained or updated by the cache management service. A subsequent request for network resource can be matched to one or more cache profiles for retrieval of applicable cached content and for generation of a partial response to the request therefrom. Non-cached content or updates to cached content can be further retrieved for generation of updating data to the partial response, and thus completing a full response to the request for network resource.

Abstract: Techniques for session transfer between resources are described in which session data for communication sessions is transferred between distinct web-based resources to enable continuation of the communication sessions as navigation between the resources occurs. In one approach, shared session storage accessible to authorized resources is employed to facilitate the transfer of session data. Code embedded in pages for different resources rendered by a browser (or other communication module) operates to store session data for communication sessions in the shared storage. When navigation occurs between different pages, authorizations of the different resources to utilize the shared session storage are determined and communication sessions that are active are maintained across page reloads for the authorized resources.

Abstract: A computing system providing virtual computing services may maintain a fleet of servers that host virtual machine instances having a wide variety of types and configurations. A service provider may rent processor and memory capacity by defining and offering various virtual machine instances to clients. Each virtual machine instance may include one or more virtual CPUs and a fixed amount of virtualized memory allocated to each virtual CPU, dependent on a predefined ratio between virtual CPU capacity and virtualized memory capacity for the instance type. Each server may include a custom, non-standard sized physical memory module containing memory devices of multiple technologies, types, or sizes on the same printed circuit board. By including custom memory modules, rather than relying only on standard memory modules, the service provider system may implement virtual machines having finer grained options for processor and memory capacity combinations, and may avoid stranding rentable resources.

Abstract: Techniques are disclosed for multiplexing a dynamic bit-rate video stream with an audio stream received by a client device in a manner that allows the resulting multiplexed stream to be played back without disruption, despite dynamic changes in the bit rate of the video stream that may occur. A content server may stream both a video stream and an audio stream to a client device for playback. The client device may multiplex the video and audio streams prior to them being presented to a playback engine for decoding and playback to a user.
