Methods and systems provide indirect and temporary access to a company's IT infrastructure and business applications. The methods/systems involve establishing an access control center (ACC) to control the access that technical support personnel may have to the company's IT infrastructure and business applications. Thin client terminals with limited functionality may then be set up in the ACC for use by the technical support personnel. The thin client terminals connect the technical support personnel to workstations outside the ACC that operate as virtual desktops. The virtual desktops in turn connect the technical support personnel to the IT infrastructure and business applications. An ACC application may be used to automatically establish the connection between the thin client terminals and the virtual desktops and the virtual desktops and the IT infrastructure and business applications.

Embodiment includes of a method and a system of network based operation of an unmanned aerial vehicle is disclosed. One system includes a drone user machine, a drone control machine, and a drone control console. The drone control machine is interfaced with the drone user machine through a network, and the drone control machine is interfaced with a drone through the drone control console. The drone control machine operates to receive user commands from the drone user machine through the network, generate drone control commands which are provided to the drone control console for controlling the drone, wherein the drone control commands are generated based on the user commands, receive video from the drone control console that was generated by a camera located on the drone, and communicate the video to the drone user machine over the network, wherein the video is displayed on a display associated with the drone user machine.

A method of constructing an application file from a plurality of files, each storing only a portion of an original application file. Each of the files stores one or more data blocks obtained from the original application file, and a location in the original application file from which each of the data blocks was obtained. At least one of the files stores the size of the original application file. The method includes allocating a block of memory the size of the original application file and storing each of the data blocks of the files in a memory location of the block of memory corresponding to the location in the original application file from which the data block was obtained. Before the block of memory includes the entire original application file, a reconstructed application file comprising the block of memory is executed to thereby at least partially implement an application.

A streaming data storage system facilitates appending of large events (e.g., up to one gigabyte) to a data segment of a streaming data storage system in a multipart upload operation. A micro-transaction data structure is created for a multipart upload of a large event, to which subparts of the multipart upload are appended during write operations. Order of the subparts is preserved, including when not appended in order, to provide for reading of the subparts in order. An event reference to the micro-transaction data structure is maintained in a data segment corresponding to the large event, and when the event reference encountered during reading, results in reading from the micro-transaction data structure when the multipart upload is complete. The reading from the micro-transaction data structure maintains the order of the large event's subparts, such that raw data is returned to an upstream reader application as the large event.

An example operation may include one or more of storing a list of unavailable blockchain peers that cannot be a lead peer of a blockchain consensus protocol, generating a pre-prepare message comprising a new block of a blockchain, appending commit messages received during a commit stage of a previous block to the blockchain, to the pre-prepare message, where the commit messages identify an unavailable blockchain peer from the list that is now available, and broadcasting the pre-prepare message with the new block and the appended commit messages to a plurality of blockchain peers.

Domain-based server-selection computer-implemented processes and machines implement an extension of RAFT consensus for leader selection based on patterns of update data proximity. Accounts involved in payment or other transactions are maintained as “sharded” data across data store instances that are split into shards according to their temporal activity. If the domain attributes for a node exceed a threshold and are greater than the other nodes, the node is designated as a leader node and the others are designated as follower nodes. This provides an additional optimization in network performance by introducing insights in normal operations within a domain in a distributed network. If the domain attributes do not exceed the threshold and/or are not greater than the other nodes, a traditional consensus algorithm is used to select leader and follower nodes.

Techniques for dynamic resource movement in heterogeneous computing environments including provider substrate extensions are described. A dynamic resource movement service of a provider network monitor conditions of heterogeneous computing environments, including provider substrate extensions of the cloud provider network, to evaluate customer-provided movement policy conditions governing when to move customer application resources from these environments, where to move the resource to, and/or how to move the customer application resources. The customer-provided movement policy conditions may be based on a variety of factors, such as a latency between end-users of the customer application and the application itself.

A system and method that enables editing capabilities of content accessed from a content management server using any type of locally-installed application is provided. In some embodiments, a content management server stores documents in a cache on the user's computer. Documents can thus be accessed and edited using the document in the local file system of the user. For example, users may open, reserve or lock, download, and edit documents with a single user action such as a click. Advantageously, the teachings of embodiments as described can be used in conjunction with content management systems for improving the user experiences involved in editing documents by providing an ‘instant’ and ‘seamless’ editing experience substantially equivalent to editing files on a local hard disk.

A set of computers can be grouped into a first group and second group of computers to receive a file object. The first group of computers are commanded to perform a peer-to-peer download of the file object from a source. The second group of computers are commanded to perform a peer-to-peer download of the file object from a computer in the first group of computers.

The present disclosure provides a method for requesting resources and a terminal. The terminal sends a first resource acquisition request for a target resource to each of first edge nodes, determines each of second edge nodes based on each first amount of the target resource returned by each of the first edge nodes, and sends a second resource acquisition request for the target resource to each of the second edge nodes.
