- 12. 12 Requirements for Cloud (I) • Multitenancy – Maximizing resource sharing • Service life cycle management – Started and ended at any time • Security • Responsiveness – Early detection and fixing of service-related problems
- 13. 13 Requirements for Cloud (II) • Intelligent service deployment – Efficient use of resources with maintaining the SLA (Service Level Agreement) • Portability – Cloud workload portability with limited service disruption • Interoperability – Working together with heterogeneous systems
- 14. 14 Requirements for Cloud (III) • Regulatory aspects – Including privacy protection • Environmental sustainability – Especially in data centers • Service reliability – QoS (quality of service) • Service access – Easy access to cloud services
- 15. 15 Requirements for Cloud (IV) • Flexibility – Supporting multiple deployment models and service categories • Accounting and charging – Various accounting and charging models and policies • Massive data processing
- 16. 16 Benefits of Cloud (I) • Achieve economies of scale • Reduce spending on infrastructure • Globalize the workforce: worldwide access • Streamline business processes: more work in less time and resource • Reduce capital costs • Pervasive accessibility: accessed anytime and anywhere
- 17. 17 Benefits of Cloud (II) • Monitor projects more effectively • Less personal training is needed • Minimize maintenance and licensing software • Improved flexibility
