This document discusses cloud computing and the role of networks in enabling cloud services. It defines cloud computing as abstracted infrastructure that can host end-customer applications and is billed by consumption. Key benefits of cloud services include easy deployment, paying only for what is used, and lower costs. However, security, performance, availability are challenges. A hybrid model is emerging where enterprises use both public cloud services and private clouds. The network is critical to delivering the dynamic, transactional, and on-demand attributes required for cloud services.

3. What is Cloud Computing?
Many Definitions
“A pool of highly scalable, abstracted
infrastructure, capable of hosting end-
customer applications, that is billed
by consumption. “ - James Staten,
Forrester Research
Terminology
SaaS – Software as a Service
IaaS – Infrastructure as a Service
PaaS – Platform as a Service
DaaS – Data as a Service
Instead of owning IT – Rent it as you need it

10. Use Case: Mogulus.com
Mogulus is a live broadcast platform on the internet
(cloud application player)
Producers can use the Mogulus browser-based Studio
application to create LIVE, scheduled and on-demand
internet television to broadcast anywhere on the web
through a single player widget.
Mogulus is entirely hosted on Amazon Web Services
(cloud infrastructure & platform customer)
On Election night Mogulus ramped to:
87000 videos @500kbps = 43.5 Gbps
486 Channels: Amazon Web elastically provided the compute
power and bandwidth to meet the increased demand
