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
HEAnet Conference, 2009
But what is cloud?

What is Cloud?
set of properties
HEAnet Conference, 2009
What is Cloud?• Elastic
• scaleable, in both directions
• Utility
• pay for what you use
• Pervasive
• access from anywhere
• state is maintained independent of location

Classic IT Problem

Are all clouds the same?• Facebook.
com• Google
Apps• Salesforce
.com, etc
SaaS
• Force.com• Google
App Engine
• Microsoft Azure, etc.
PaaS
• Amazon (EC2)
• Cisco (Unified
Communications)
• MANTICORE, etc.
IaaS
HEAnet Conference, 2009
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

Billing?• one X.509 cert later
• Select one of >3,500 AMIs (Virtual machine images)
• http://calculator.s3.amazonaws.com/calc5.html
• Costs (OpEx):
• 1 small machine month ≈ $72.00 ( $864 / year )
• without storage
• without data transfer in and out
HEAnet Conference, 2009
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!
HEAnet Conference, 2009
Storage
HEAnet Conference, 2009
Storage
HEAnet Conference, 2009
Storage• Transfer costs!
• Completely unlike NREN usage / costing model
• AWS (Amazon S3):
• in : $0.10 / GB
• out: 10TB @ $0.17 / GB
• 40TB @ $0.13 / GB
• 100TB @ $0.11 / GB
• >150TB @ $0.10 / GB

Risks• Hidden Costs?
• data transfer
• per transaction cost
• Vendor Lock-in
• feature compatibility between vendors
• cost of transfer
• Lack of competition / pricing control?
• Software Licensing
HEAnet Conference, 2009
Risks• Data Privacy
• Legislative controls?
• Data Protection compliance
• User security ( twitter.com )
• Data integrity
• off-site backup
• no guarantees! (T-mobile Sidekick / Danger )
• Network failure

Risks
HEAnet Conference, 2009
Saving money• Users
• CapEx -> OpEx
• Utility pricing
• Providers
• Cloud centric platforms (Cisco UCS, etc.)
• Virtualisation
• Save money by becoming a cloud user too
HEAnet Conference, 2009
Quality?• Gartner 2008 survey, 333 UK & Irish
businesses:
• Low level of approval for SaaS
• Overall satisfaction ‘lukewarm’
• High cost of service
• Difficult to integrate
HEAnet Conference, 2009
What have I NOT talked about?• Private clouds
• Security (in any real sense)
• Legislative compliance (in any real sense)
• Green / Environmental impact
• Comparisons between workloads
• desktop v researcher, etc.
HEAnet Conference, 2009
Next steps• Open Standards
• OPaaS
• SNIA cloud storage initiative
• Networking
• quality
• cost model
• availability
• Software Licensing
• Start virtualising
