CLOUD COMPUTING SERVICES: WHY?
§ Economics
§ Cost/Efficiency
§ Pay per Use
§ Elasticity
§ Scale very quickly as needed
§ No additional infrastructure investment
§ Ubiquity
§ Available anywhere/anytime
§ Instant access (credit card)

WHAT DOES CLOUD DO FOR ENTERPRISES?
• Costs
§ Sharing of resources like server, storage, security and network
• Elasticity
§ Ability to scale up and down quickly according to business needs
§ Dynamically allocate/reallocate resources for certain applications to
support a LOB
• Self-Provisioning
§ Users can provision for application, server, storage, network and
security on their own
• Overall benefit:
§ Faster turnaround time for users and business
§ Less dependence on IT

Ports can be added to a

SCALING THE DATA PLANE
So, we separate the
line cards from the fabric.
And extend the copper
traces with fiber links.
For redundancy add
multiple devices.
