摘要： A switching device for heterojunction integrated circuits is disclosed. According to one aspect, the switching device is configured to protect a circuit from an electro-static discharge (ESD) event. The switching device includes a second base contact region that is configured to be electrically floating, a first base contact region and a collector contact region that are coupled to a first input terminal of the switching device, and an emitter contact region that is coupled to a second input terminal of the switching device. Due in part to capacitive coupling between the first base contact region and the second base contact region, the switching device exhibits a low transient trigger voltage and a fast response to ESD events. Further, the switching device exhibits a high DC trigger voltage (for example, greater than 20V), while maintaining relatively low leakage current during operation (for example, less than about 0.5 μA at 20V DC.

摘要： Configuration drift refers to changes made over time that cause a computer or service to deviate from a desired configuration. Configuration drift of a group of machines can be managed by defining configuration intent. Intent is defined by defining a configuration baseline comprised of a collection of related configuration rules. Configuration rules include settings, and targets which can be any managed entity that enables reporting of non-compliance at a more granular level. A configuration baseline can be completed by reading configuration rules from one or more well-configured computers. Configuration drift is assessed by comparing actual values to the configuration baseline values and is reported at a managed entity level instead of at a machine level. Remediation, returning the computer to a state of compliance with the configuration baseline, can be performed on demand. Remediations performed over time are retained and applied to a new instance of the service to eliminate configuration drift on the new instance.

摘要： The subject disclosure generally relates to provisioning devices via a network service, such as a cloud service. A profile component can authenticate a user of a device with a cloud service, and determine services maintained by the network service that are associated with the user. A reception component can receive a request for a set of services from the device, and a services component can obtain the set of services from the network service, and provision the device based on the set of services. Provisioning the device can include downloading the services to the device, or including the services in a virtual machine executing in the network service.

摘要： Techniques are described to allow substation of blocks into a virtual machine image of an executing virtual machine. A patch may be applied to a first virtual machine image. One or more blocks modified by the patch are identified and copied to a host having a virtual machine executing from a virtual machine image that is based on the first virtual machine image (prior to the patch). While the virtual machine is executing, the substitution blocks are applied (supersede) corresponding original blocks in the virtual machine image. A guest operating system in the virtual machine may either begin using an executable file in a substitution block. In addition, the guest operating system may be forced to flush from memory and cache executable code replaced by the substitution block.

摘要： A logical communication path is provided between a target virtual machine (VM) and a host or application communicating with the VM. The target VM runs on a hypervisor host that has a hypervisor and a proxy agent. The hypervisor manages execution of the VM. A mapping is maintained indicating which VMs execute on which hosts. When the host or application is to send a message or packet to the target VM, the mapping is consulted and the hypervisor host hosting the target VM is identified. The message or packet, which may identify the target VM, is transmitted to the hypervisor host. A proxy agent at the hypervisor host selects a communication channel between the hypervisor and the target VM. The hypervisor then passes the message or packet through the selected channel to the target VM.
