Cloud computing provides resources on demand
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS)
Virtualisation
Flexible allocation of logically
partitioned resources at three service
layers
The definition of Cloud Computing
“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access
to a shared pool of configurable computing resources (e.g. networks, servers, storage,
applications and services) that can be rapidly provisioned and released with minimal
management effort or service provider interaction.” The National Institute of Standards and Technology

Virtualisation can reduce CPE complexity and cost
Service Platform
IP Edge
Aggregation network
CPE is necessary as the
demarcation point between the
operator and subscriber network
A considerable amount of functionality can be implemented as virtual CPEs on cloud
and middleware platforms at various locations in the operator’s network.
