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

+ Service Level Agreement
+ An SLA is an agreement between a service provider and a customer to
