Abstract: Methods and apparatus for hardware support for low latency microservice deployments in switches. A switch is communicatively coupled via a network or fabric to a plurality of platforms configured to implement one or more microservices. The microservices are used to perform a distributed workload, job, or task as defined by a corresponding graph representation of the microservices including vertices (also referred to as nodes) associated with microservices and edges defining communication between microservices. The graph representation also defines dependencies between microservices. The switch is configured to schedule execution of the graph of microservices on the plurality of platforms, including generating an initial schedule that is dynamically revised during runtime in consideration of performance telemetry data for the microservices received from the platforms and network/fabric utilization monitored onboard the switch.

Abstract: Aspects of the disclosure relate to real-time management of data container generation, authorization, and throttling. In some embodiments, a computing platform may receive and store data container management files, each associated with a different data container. The computing platform may thereafter receive a first data container and retrieve a first data container management file associated with the first data container. The computing platform may perform a preliminary analysis of the first data container to determine whether the first data container is complete. If the first data container is incomplete, the computing platform may send one or more analysis messages to a data container generation module to queue the first data container and retrieve an identification element associated with a missing data set. The computing platform may then retrieve the missing data set and generate an updated first data container by supplementing the first data container with the missing data set.

Abstract: Embodiments herein relate to providing uniform servicing of workloads at a set of servers in a computer network. A platform determines and meets the performance requirements of a workload by scaling a performance capability of a group of processing units such as central processing units (CPUs) which are assigned to service the workload. This can involve increasing the power (P) state of one or more of the processing units to a highest P state in the group, so that every processing units in the group provides the same performance for a given workload. The platform can manage scaling of the processing units performance by reading a performance profile list which indicates minimum and maximum scaling points for programs that are executed to service the workload.

Abstract: The present disclosure is a new and innovative system, methods and apparatus live storage migration. In an example, a system includes a memory and processor in communication with the memory. The processor is configured to receive a request to perform live storage migration of a guest managed by a source hypervisor on a source machine to a destination machine. The guest is configured to store data in blocks of block storage. The source hypervisor, executing on the processor, receives a hint for each block of data in block storage of the guest via an agent of the guest, wherein the hint relates to properties of a specific block of data. The source hypervisor then determines an efficient prioritization that identifies which blocks to copy and in what order as a part of the live storage migration based on the hints received from the agent. The source hypervisor then copies the blocks of data identified for copying in the migration based on the prioritization, saving time and computational resources.

Abstract: A method for dynamically optimizing and modifying allocation of virtual resources to processes includes allocating, by a first hypervisor, a first amount of a first virtual resource to a process executing in a virtual machine on a first machine. An agent, in communication with a resource allocation process executing in the virtual machine, determines a second amount of the first virtual resource to be utilized by the process. A scheduler receives an identification of the determined second amount and directs migration of the process to a second machine. A second hypervisor executing on the second machine allocates a third amount of the first virtual resource, the third amount substantially similar to the second amount. The method includes communicating, by the resource allocation process, to the process, that the first amount of the first virtual resource is allocated to the at least one process.
