A method of rotating assigned credentials for client devices registering with servers may include determining that assigned credentials for a client device are expired; in response to determining that the assigned credentials have expired, generating new credentials for the client device; sending the new credentials to the client device; generating an encrypted version of the new credentials and storing the encrypted version of the new credentials at the server during a grace period, where during the grace period the client device can be authenticated using the assigned credentials or the new credentials; and deleting the encrypted version of the new credentials at an expiration of the grace period.

Systems, methods, and computer-readable media for extrapolating information display visualizations are disclosed. The systems and methods may involve maintaining a board with a plurality of items, each item defined by a row of cells, and wherein each cell is configured to contain data and is associated with a column heading; linking at least a first column to at least a second column so that a change in data in a cell of the at least first column causes a change in data of a cell in the at least second column; receiving a first selection of a particular item from the board, wherein the particular item includes a plurality of cells with data in each cell, and wherein data in a first cell of the plurality of cells is linked to data in a second cell of the plurality of cells; upon receipt of the first selection.

Technology is generally described for automating the project management and execution of data migration from a source email system to a destination email system. In some examples, the technology can include receiving a domain name of a second computing system; obtaining domain name system (DNS) records for the received domain name; determining an email hosting provider for the second computing system; determining, by the processor, based on the obtained DNS records, an email system service type of the source email system on the second computing system; discovering mailboxes and message delivery rules of the source email system; displaying customization options for migrating discovered source email system mailboxes; migrating data items from the source email system to the destination email system; and managing migration of data from source email system client computing devices to the destination email system.

A method and apparatus for distribution of applications amongst a number of servers, ensuring that changes to application data on a master for that application are asynchronously replicated to a number of slaves for that application. Servers may be located in geographically diverse locations; the invention permits data replication over high-latency and lossy network connections and failure-tolerance under hardware and network failure conditions. Access to applications is mediated by a distributed protocol handler which allows any request for any application to be addressed to any server, and which, when working in tandem with the replication system, pauses connections momentarily to allow seamless, consistent live-migration of applications and their state between servers. Additionally, a system which controls the aforementioned live-migration based on dynamic measurement of load generated by each application and the topological preferences of each application, in order to automatically keep servers at an optimum utilisation level.

A gateway provides duplex-directional, multimedia ad hoc mesh networking, peer-to-peer direct communications, power optimization, dynamic configuration, and data management, while operating within various devices and network topologies. A multitasking virtual machine monitor for mobile networked devices, that is capable of functional expandability and portability to various operating environments, interoperability with a variety of operating systems, the Gateway Control System (GCS) performs functional capabilities in both a local and a networked topology using local and remote hardware and software. Software within the GCS is partitioned into sequentially, autonomous code, referred to herein as “modules,” each module being configured to communicate with hardware and other gateway modules. Collectively, all gateway modules are referred to herein as the gateway stack (GS). Each member of the GS can be turned on or off, downloaded from a remote site, and dynamically configured.

A data copy method comprises: acquiring, by a destination server, a data block identifier, version information and hole information; transmitting, by the destination server, the data block identifier, the version information and the hole information to a source terminal server so as to enable the source server to find corresponding data according to the data block identifier, the version information and the hole information; receiving, by the destination server, a response message carrying the data transmitted by the source server and copying the data to a hole corresponding to the data block identifier, the version information and the hole according to the response message.
