Reference Definition
“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.”

Evolution vs. Revolution
Cloud 1.0
Software/Storage as a Service (SaaS)
Simple services, simple architecture
ex: email, billing, CRM, collaboration, gaming, storage… 1.0
Cloud 2.0
Infrastructure as a Service (IaaS)
Moving the Enterprise-class infrastructure into the Cloud
Requirements: No infrastructure management impacts
No infrastructure performance impacts
No infrastructure security impacts

Discover resources under its control
Maintain view of all client ports,
inter-DC WAN links, E2E paths
Available/used bandwidth for each link
Latency, cost, specific routes…
Dynamically allocate, adjust, delete E2E
network resources, as required
Immediately on-demand or scheduled
