A measure of the performance of a service, such as a network or a cloud service
In cloud computing, Quality of Service (QoS) is a measure of the performance of a service, such as a network or a cloud service. It's a way to assess the performance of a service and ensure that it meets the required standards.
Quality of Service works by setting performance targets for a service and then measuring the service's performance against these targets.
A cloud service provider, CloudServe, might use QoS to ensure that its services meet the needs of its customers. For example, it might set a target for 99.9% uptime and then monitor its services to ensure this target is met. If the service's uptime falls below this target, CloudServe can take action to improve it.
A device that distributes network traffic across a number of servers to enhance the responsiveness and availability of applications, websites, and other services.
A characteristic of a system which aims to ensure an agreed level of performance, usually uptime, for a higher than normal period.
