Engineering – Private Cloud
• Project Services Network:
- Brought IT back in-house
- Remodeled in the image of Google, Salesforce.com, YouTube,
Amazon… but not sold internally as ‘cloud’
- Virtualized, multi-tenanted, multiple chargeback mechanisms
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
• Outcome:
- 30% infrastructure cost savings
- Key benefits: agility, collaboration, location-independence
- Next up – put its user community in the cloud (desktops) – AWS?
- Key advantage: project-based
- Barrier – cultural
![Page 15: Journeys in the Clouds - ETSIdocbox.etsi.org/Workshop/2009/200912_GRID/BARR_451GROUP.pdf · - Next up –put its user community in the cloud (desktops) –AWS? - Key advantage: project-based](https://reader036.vdocuments.us/reader036/viewer/2022070802/5f02ea8d7e708231d406a559/html5/thumbnails/15.jpg)
Transportation – PaaS• Project Halo:
- Use cloud to extend its enterprise operationally and commercially into the
airport space
- Move departure control system onto a .NET service bus with universal access to
run EasyJet and third-party apps
- Deploy over secure VPNs via local 3G operators
- Retain Savvis for certain dedicated apps
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
• Goal:- Remove dependence on service desks
- Drive down cost and time to market
- Create private cloud for some operations, use public cloud for others
- Flexibility to support its ‘bursty’ model

Pharmaceutical• Project:
- Longtime grid user has been trying to do this with its own datacenters
- Three public cloud projects testing peak demand offload
- Using insensitive data and NONMEM apps
- Run HPC workloads (and grid middleware) on Amazon
• Goal:
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
• Goal:- Reduce capex, improve time to market and provisioning
- Use cloud instead of buying additional CPUs
- Also considering IBM and Microsoft
- The greater the grid utility, the less economic benefit to use cloud
- Wants to simply ‘show up with code’ (PaaS) and bypass IaaS altogether

E-tailer
• Project:
- Use GoGrid public cloud for QA, testing and more
- Will move entire search engine marketing to cloud
- Also considering Amazon and IBM
- Cloud can help improve 3% utilization due to seasonal sales model?
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
• Goals and benefits:
- Reduce capex, improve time to market and provisioning
- Reduced QA deployment from two days to 30 minutes
- Multiple weekly changes to website instead of one
- Now considering PaaS, SaaS
- Organizational and cultural barriers

Energy• Challenge:
- Internal provisioning = weeks/months
- Developers went to AWS
- Guerrilla activity uncovered
• Innovation:
- Enfranchise use
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
- Enfranchise use
- Extend existing management tools to support hybrid model with rules
and reporting
- Self-service, service catalogs
- Baked-in process change?
- ‘Real’ cloud strategy under way…

- Already uses external services for CRM, HR, etc.
- Cost allocation is key
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
• Challenges:
- Meeting contractual obligations in the cloud
- New spending – capex or cloud?

Private Hosted, Enterprise Public Clouds
• Cloud Projects:
- Create private hosted, public enterprise clouds
• Goals:
- Support internal, external customers
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
- Support internal, external customers
- Turn fixed costs into variable costs
• Challenges:

FSI – From Grid to Cloud?
- Investment banking groups champion use of grid for HPC
- Benefits realized from shared resources
- Same groups asked to extend shared infrastructure to support additional activities (e.g., retail banking)
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
support additional activities (e.g., retail banking)
• Features:
- Improved utilization
- Utility cost allocation
- Silos to internal cloud: projected savings = 30%
- Public cloud experimentation

Some Drivers of Enterprise Cloud
• Cost reduction in the short term
• IT staff already using cloud services
• Avoidance of capital expenditure
• Reducing footprint – physical and carbon
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
• Reducing footprint – physical and carbon
• Managing underutilized resources
• Flexibility in scaling IT up and down
• Rolling out new services rapidly
• Accelerated time to market

Some Barriers to Adoption
• Security – data, application isolation, shared networks,
compliance
• ISV licensing – adapting 20+-year models to new per-hour
models
• Support SLAs – strength, ability to deliver, remuneration if
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
• Support SLAs – strength, ability to deliver, remuneration if
failure
• Corporate governance policies – changes often required
• Interoperability – data format, data management
• Uncertainties of the business model, cloud vendor viability
• Direct threat to enterprise IT workers’ jobs

What We Are Seeing
• PVC: people are starting to talk about an infrastructure
progression from physical to virtual to clouds
• Public/private cloud – 30% infrastructure cost savings
• 25%+ of capacity in the cloud
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
• 25%+ of capacity in the cloud
• Benchmarking against Amazon
– AMI becoming a de facto standard?
• Cost allocation, self-service

What We Are Hearing
• “There aren’t any tools… There are too many tools… The tools don’t work the way I do!”
• How do I get from where I am today to cloud?
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
cloud?
• Data Management
• How/when should I put an app on the cloud – and can I leave?
• How far up the stack will internal clouds go?
• Licensing in the cloud is a stumbling block

What We Expect
• Once specific concerns are overcome, external
clouds will be used on a production basis
• Almost without exception, IaaS will lead to an
examination of PaaS
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
examination of PaaS
• ‘Standards’ won’t hold up or advance clouds –
economics will
• A few public clouds, but many private clouds
• Benefits will depend mostly upon mindset?

Cloud Computing Is Dangerous
• Danger illustrates the data management/ security/availability issue– Major server outage caused loss of significant personal data at Microsoft’s aptly-named subsidiary, Danger
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
at Microsoft’s aptly-named subsidiary, Danger
• Where is the SLA?
• Compete with internal IT
• Can clouds cope with fast markets?
• Is a cloud cheaper?

Recommendations
•Experiment with basic apps on multiple
clouds, plan to span internal/external
•New project – no servers?
John Barr : Grids, Clouds & Service Infrastructures 2009 Nice
•New project – no servers?
•Cloud scares suppliers; put it on RFPs
• It’s a different sell
