12. Service categories & capabilities types Y.3500 Cloud Service Categories Cloud Capabilities Types InfrastructurePlatformApplication Compute as a Service X Communication as a Service XX Data Storage as a Service XXX Infrastructure as a Service X Network as a Service XXX Platform as a Service X Software as a Service X

13. Infrastructure as a service (Y.3513) computing service functions allow CSC to provision and use processing resources. storage service functions allow CSC to use storage resources.. network service functions allow CSC to use networking resources.

14. Infrastructure as a service (cont.)

15. Network as a service (Y.3512) NaaS Application: application capabilities type of service where NaaS CSC can use network applications provided by CSP. Examples of NaaS applications include virtual Router, virtual Content Delivery Network, virtualised Evolved Packet Core and virtual Firewall. NaaS Platform: platform capabilities type of service where NaaS CSC can use the network platform provided by NaaS CSP. The NaaS platform offers one or more software execution environments and one or more programming languages to deploy, manage and run customer-created or customer-acquired network applications NaaS Connectivity: infrastructure capabilities type of service where NaaS CSC can provision and use networking connectivity resources provided by NaaS CSP. This includes for example flexible and extended virtual private network (VPN), bandwidth on demand. In this category, CSP offers network connections between two or more endpoints, which may include additional network functionalities.

16. Network as a service (cont.)

17. Desktop as a service (Y.3503) A cloud service category in which the capabilities provided to the cloud service customer are the ability to build, configure, manage, store, execute and deliver users' desktop functions remotely CSC Customer CSP Provider

18. Desktop as a service (cont.)

19. Inter cloud computing (Y.3511)

20. Cloud Management (Y.3520) Single Cloud

21. Multi Cloud Management Enabled by SES concept
