GESSI: SALMon Monitoring the cloud

Determine the QoS of cloud systems in order to select the best cloud.

13

GESSI: SALMon Self-Adaptive SBAs

Monitor the constituent services of an SBA to enable Self-Adaptive SBAs

14

GESSI: SALMon Service Selection

Monitor the QoS of services to provide a service selection framework based on the Non-Functional Requirements

15

GESSI: SALMon Prediction accuracy

Monitor the results of predictive services and compare them automatically with services providing the information once the predicted events have occurred.
