Abstract: Embodiments of systems, apparatuses and methods provide enhanced function as a service (FaaS) to users, e.g., computer developers and cloud service providers (CSPs). A computing system configured to provide such enhanced FaaS service include one or more controls architectural subsystems, software and orchestration subsystems, network and storage subsystems, and security subsystems. The computing system executes functions in response to events triggered by the users in an execution environment provided by the architectural subsystems, which represent an abstraction of execution management and shield the users from the burden of managing the execution. The software and orchestration subsystems allocate computing resources for the function execution by intelligently spinning up and down containers for function code with decreased instantiation latency and increased execution scalability while maintaining secured execution.

Abstract: An example non-transitory machine-readable storage medium storing machine-readable instructions which when executed cause a processor to obtain stored bits stored on a flash memory, each of the stored bits in a set state or an unset state. The processor further obtains target bits, each of the target bits in the set state or the unset state, wherein each target bit corresponds to a stored bit to update the stored bit. The processor further determines whether, for one stored bit in the set state, the corresponding target bit is in the unset state. When the determination is positive, the processor sets the stored bits to the unset state and, after setting the stored bits to the unset state, updates the stored bits to match the corresponding target bits. When the determination is negative, the processor updates the stored bits to match the corresponding target bits.

Abstract: An example of an apparatus is provided. The apparatus includes a power supply to connect to a power source. The power supply is to receive and to distribute a total power from the power source. The apparatus further includes a first device to receive a first portion of the total power from the power supply. The apparatus further includes a second device to receive a second portion of the total power from the power supply. A sum of the first portion and the second portion is the total power. In addition, the apparatus includes a controller to control the second device, wherein the controller is to determine the total power demanded by the first device and the second device. The controller is to reduce the second portion of the total power and to restore the second portion of the total power.

The system can place the computing device to a threshold power state responsive to the NIC receiving WOL support.
