The subject disclosure is directed towards components in different server clusters, e.g., comprising software components such as components of a distributed computing system. Components are available for use by distributed computing system applications, yet managed by the distributed computing system runtime such that only a single instance can be activated and exist within communicating (non-partitioned) clusters. Also described is recovery from a situation in which no longer partitioned clusters each have created the same component.

Systems, methods, and computer-readable storage devices are disclosed for improved concurrency of users of a shared virtual environment. One method including: transmitting, to each single player client of, chunks of world chunk data of a shared virtual environment; receiving, at one or more virtual environment servers from each single player client connected to the shared virtual environment, state data of each user of a respective single player client connected to the shared virtual environment, wherein the single player client of each user manages state data of the user within the one or more virtual environment servers; periodically monitoring, from each user of the single player client connected to the shared virtual environment, updated state data for the user of a respective single player client connected to the shared virtual environment; storing, for the shared virtual environment in a database connected to one or more virtual environment servers, the updated state data for each user of the single player client; and periodically transmitting, for each user of the single player client, the updated state data of other users of the single player client within a predetermined distance of the user of the single player client.

Technologies are described herein for event delivery and stream processing utilizing virtual processing agents. Upon receiving an event publication in a queue, a runtime system identifies one or more virtual processing agents that might be interested in, but have not explicitly subscribed to, the published event. Event information of the published event is then delivered to the identified virtual processing agents. Prior to the actual delivery, the runtime system further determines if the virtual processing agents have been activated and activates those processing agents that have not been activated. Based on the received event information, some of the virtual processing agents might decide to explicitly submit subscriptions to receive more events from the queue. The explicit subscriptions will trigger the runtime system to deliver the subscribed events to the processing agents, which might include past events that have been published in the queue before the explicit subscription is received.

Stream processing utilizing virtual processing agents

The subject disclosure is directed towards virtual components, e.g., comprising software components such as virtual components of a distributed computing system. Virtual components are available for use by distributed computing system applications, yet managed by the distributed computing system runtime transparent to the application with respect to automatic activation and deactivation on runtime-selected distributed computing system servers. Virtualization of virtual components is based upon mapping virtual components to their physical instantiations that are currently running, such as maintained in a global data store.

The claimed subject matter relates to an architecture or arrangement that can limit access to sensitive information by means of encryption. In particular, data obtained from a payment instrument at, e.g., a Point-Of-Sale (POS) location can be encrypted at an early stage such that a POS (or another) application does not have access to the data in an unencrypted form and/or does not have access to a means for decrypting the data. For example, a Public Key Infrastructure (PKI) arrangement can be employed such that a back-end payment processor can define encryption algorithms, associate itself with a public key, and maintain a private key for decryption. The public key can be delivered to the POS location and employed for data encryption, and, moreover, the PKI can be regulated by the more trusted parties.

Securing payment data

The deployment of multiple embedded operating system components provides a designer with flexibility when customizing an embedded operating system for a target computing device. The embedded operating system components provide extra features to expand the functionality of the target computing device. The ease with which the designer may select various embedded operating system components to deploy from an originating computing device to the target computing device simplifies the design process. Configuration data of a core embedded operating system and configuration data of the deployed embedded operating system components are merged and any conflicts between configuration data are automatically resolved without rebooting the target computing device.
