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!)

Cloud Users Vs Providers

Gareth,

Could not afford the cloud-enabled audience voting pads this year, sorry!Maybe in 2010?

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


But what is cloud?


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

€€€


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


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


Sign up to AWS


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


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


Data integrity

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


Risks


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


HEAnet Cloud Strategy• Over to you!

• do you have a cloud strategy?

• how can we help?

• HEAnet Cloud Strategy

• inform us


The Cloud• Case studies:

• Paul Doyle (DIT)

• Aidan McDonald (Cork IT)

• Ruth Lynch (UCD)

• The commercial / educational aspects of cloud:

• Michael D. King (Vice President, IBM Global Education Industry)
