Need to write an article on Qos Challenges In Cloud Computing covering the following
Measures to maintain Quality: The following are the Measures to be checked to assess the QoS of cloud Service providers :
• Measuring service availability: functions to be covered, defining un-availability and metrics.
• Incident response: response timings, severity classification, incident management capability.
• Server elasticity and load tolerance: tests, resources to be monitored, customer choices.
• Data lifecycle management: monitoring backup and recovery, testing, certification
• Technical compliance and vulnerability management: definition of security options, patches and updates, vulnerability discovery and reporting
• change management: notice to customers, triggers for serious events, notice of major changes
• Data Isolation: monitoring types– memory, disks and failure criteria, independent testing and certification
• Log management and forensics: checks frequency, cross checks the customers systems, events logging.
