    IOPS
      Input/Output Operations Per Second
+     A performance measurement used to benchmark storage devices.

+
+   Kubernetes
+     k8s
+     Kubernetes is an open-source container-orchestration system for automating
+     deployment, scaling and management of containerized applications.
+     It is one of the contexts supported in Yardstick.
+
+   NFV
+     Network Function Virtualization
+     NFV is an initiative to take network services which were traditionally run
+     on proprietary, dedicated hardware, and virtualize them to run on general
+     purpose hardware.
+
+   NFVI
+     Network Function Virtualization Infrastructure
+     The servers, routers, switches, etc on which the NFV system runs.

+   OpenStack
+      OpenStack is a cloud operating system that controls pools of compute,
+      storage, and networking resources. OpenStack is an open source project
+      licensed under the Apache License 2.0.

    QoS
      Quality of Service
+     The ability to guarantee certain network or storage requirements to
+     satisfy a Service Level Agreement (SLA) between an application provider
+     and end users.
+     Typically includes performance requirements like networking bandwidth,
+     latency, jitter correction, and reliability as well as storage
+     performance in Input/Output Operations Per Second (IOPS), throttling
+     agreements, and performance expectations at peak load
+
+   SLA
+     Service Level Agreement
+     An SLA is an agreement between a service provider and a customer to
+     provide a certain level of service/performance.
+
+   SR-IOV
+     Single Root IO Virtualization
+     A specification that, when implemented by a physical PCIe
+     device, enables it to appear as multiple separate PCIe devices. This
+     enables multiple virtualized guests to share direct access to the
+     physical device.

    VM
      Virtual Machine
+     An operating system instance that runs on top of a hypervisor.
