Can Cloud save me money?• Cloud service users:
• with variable loads
• requiring scaling up and back at short notice
• want a service that’s already available as SaaS
• YES! (maybe!)
• Cloud service providers:
• generally, NO!
• unless you are selling spare capacity
• virtualisation / economies of scale might contradict this

• Utility
• pay for what you use
• Pervasive
• access from anywhere
• state is maintained independent of location

Why should I care?• Are you ready for the Cloud?
• Conversion of CapEx to OpEx
• variable costs
• unbounded costs?
• Ubiquitous, reliable networking vital
• though often not high bandwidth
• what‘s your campus 802.11 coverage like? Wimax?
• Security

Providers• Must suffer capital expense
• but might ‘overflow’ on to another cloud
• Must predict future trends
• Provision of power/cooling/housing
• Provision of compute/storage/network
• Better become a cloud user too!
