Cloud Does the ‘Cloud’ havea Silver Lining? Gareth Eason
Summary • Should I care about cloud? • YES! • Will cloud solve all my compute and storage problems? Is it a magic silver bullet? • NO! • (sorry!)
Audience Participation • Q. Who considers themselves • a Cloud User? • a Cloud Provider?
Results Gareth, Could not afford the cloud-enabled audience voting pads this year, sorry! Maybe in 2010? John
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
What is Cloud? Concept
What is Cloud? set of properties
What is Cloud? • Elastic • scaleable, in both directions • 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
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
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!
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
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
Saving money • Users • CapEx -> OpEx • Utility pricing • Providers • Cloud centric platforms (Cisco UCS, etc.) • Virtualisation • Save money by becoming a cloud user too
Quality? • Gartner 2008 survey, 333 UK & Irish businesses: • Low level of approval for SaaS • Overall satisfaction ‘lukewarm’ • High cost of service • Difficult to integrate
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.
Next steps • Open Standards • OPaaS • SNIA cloud storage initiative • Networking • quality • cost model • availability • Software Licensing • Start virtualising
