Match the following cloud service quality metrics with their descriptions:

SLA violations = Can lead to penalties receivable from the cloud provider Limited portability = Challenging to move custom-built software between different cloud providers Multi-regional compliance = Legal issues related to data hosting in different regions Data accessibility = Government agencies' access to hosted data

Match the following challenges with their impact on cloud consumer solutions:

Lack of industry standards = Proprietary public cloud environments Dependencies on proprietary environments = Difficulty in moving software across clouds Legal restrictions on data hosting = Requirement to keep UK citizen's data within UK Government access to hosted data = Data accessibility by specific agencies

Match the following statements with the correct cloud service quality concern:

Tracking actual level of service = Monitoring provided services for quality assurance Affordability and convenience in data center locations = Multi-regional compliance challenges UK laws on personal data hosting = Legal restrictions affecting cloud provider and consumer USA government access to hosted data = Data accessibility concerns for cloud consumers

Match the following with their impact on business: Availability

Loss of customer satisfaction and business = Unavailable database dealing with clients’ orders Profit and customer retention = Availability of IT resources Increase in processing demand = Automatic release of IT resources Dynamic scalability = Avoids over-provisioning and under-provisioning Signup and view all the answers

Match the following with their importance in cloud computing: Reliability

Continual business data processing = Importance of IT resource reliability Response time = Importance of IT resource reliability Failure of any IT resource can cause system collapse = Reliability of IT resources Modular structure and resource redundancy in cloud = Increases availability and reliability Signup and view all the answers

Match the following with their role in ensuring quality cloud service: Service Level Agreement (SLA)

Legal agreement between cloud provider and user = Guaranteed level of availability and reliability Recovery time after failure = Added penalty for downtime Time when system remains unavailable after failure = Recovery time Modular structure and resource redundancy in cloud = Improves availability, reliability, and recovery time Signup and view all the answers

Match the following criteria with their implications for offering software as a Service (SaaS):

Variable response time and network delays = Not suitable for critical software like flight control systems Bulk-consumer data = Infeasible to transfer in real-time over WAN to SaaS provider Critical software = Challenging to achieve continuous acceptable reliability in public SaaS SaaS billing options = Includes factors like number of users, time in use, network bandwidth consumed Signup and view all the answers
