Abstract: Virtual machine management is provided. A virtual machine is started automatically based on a custom resource definition of the virtual machine in response to the receiving the custom resource definition of the virtual machine. A container is generated to run an application workload in the virtual machine based on a container configuration file in response to the virtual machine starting. The application workload is deployed on the container automatically based on a container image corresponding to the container. The application workload is run on the container automatically in accordance with a definition of the application workload.

Abstract: Embodiments are directed to deploying a workload on the best/highest performance node. Nodes configured to accommodate a request for a workload are selected. Information is collected on each of the selected nodes and the workload. Predicted response times expected for the workload running on each of the selected nodes are determined. The workload is deployed on a node of the selected nodes, the node having a corresponding predicted response time for the workload, the workload being deployed on the node based at least in part on the corresponding predicted response time.

Abstract: User data security is provided. Encrypted user data are identified in a virtual machine. A private key of a public/private cryptographic key pair corresponding to a user is retrieved. The encrypted user data is decrypted within the virtual machine utilizing the private key corresponding to the user to form decrypted user data. The encrypted user data are replaced in the virtual machine with the decrypted user data. The decrypted user data is processed in the virtual machine to perform a service in a cloud environment.

Abstract: A stepless adjustable telescopic device includes a first support, a second support, and a folding arm connecting the first support to the second support. The folding arm includes a first quadrangular structure, a second quadrangular structure, and a power support device connected to the first quadrangular structure. A first end of the first quadrangular structure is rotatably connected to the first support. A first end of the second quadrangular structure is rotatably connected to the second support, and a second end of the second quadrangular structure is rotatably connected to a second end of the first quadrangular structure via a rotary connection structure. The power support device and the first quadrangular structure form a triangular structure, and the power support device is configured to drive the first quadrangular structure to rotate such that the first quadrangular structure drives the second quadrangular structure to rotate synchronously with the first quadrangular structure.

Abstract: An electric lifting frame includes a lifting pedestal and a remote control. The lifting pedestal includes a supporting base, a lifting rod detachably connected to the supporting base, and a transmission mechanism, a motor, a controller, and a power supply provided at the lifting rod. The motor is configured to effect extension and retraction of the lifting rod via the transmission mechanism. The controller is configured to control starting and stopping and a rotation direction of the motor. The power supply is configured to supply electric energy to the motor and the controller. The controller is further configured to determine a remaining capacity of the power supply and calculate a number of remaining available times of use according to the remaining capacity, a power of the motor, and a stroke of the transmission mechanism.

Abstract: A multifunctional holder includes a fixation device configured to fix the multifunctional holder on another device, a support device fixed on the fixation device, and an adjustment device rotatably connected to the support device and configured to mount a display terminal. A position and an angle of the display terminal is controlled by a rotation and an adjustment of the adjustment device.

Abstract: A display cart includes a pedestal, a lifting frame, and a power supply apparatus including a battery arranged within the pedestal and configured to supply power to an electric apparatus, an external power supply configured to supply power to the battery and/or the electric apparatus, and a capacity management system. The capacity management system includes a control device, a power delivery device, and a capacity statistic device. The control device determines output power of the electric apparatus. The capacity statistic device determines a remaining capacity in the battery, calculates a remaining power supply duration according to the output power of the electric apparatus, and sends a statistic result to the control device. The control device further controls the power delivery device to supply power to the electric apparatus according to the statistic result.
