Cloud Computing
Definition per ITU-T Y.3500
“paradigm for enabling network access to a
scalable and elastic pool of shareable physical or
virtual resources with self-service provisioning and
administration on-demand”
NOTE – Examples of resources include servers, operating
systems, networks, software, applications, and storage
equipment.

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.
Infrastructure as a service (cont.)
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 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.
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
Network as a service (cont.)
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
