Security

• Physical security of the location/data centre where cloud service is hosted
• Application & data security
• Security related to multi-tenancy
• Data encryption management
• User access management

Quality of Service

• Performance guarantees (through SLAs)
• Availability of service
• Service reliability
• Network performance and latency
