12. Money: are there benefits of scale in “small scale” ? Cost Leadership • Optimize your presence • Hardware • Optimize cost of individual datacenter components • Economies of scale • Differentiation • Move to • virtualization/cloud services • Service • Optimize return of entire datacenter • Flexibility & elasticity Business requirements • Absolute lowest CapEx and OpEx • Instant time to market • Direct B2T connection • Global scalability • Flexible demand support Technology requirements • Massive datacenters • Large orders • Intense energy focus • Elastic on global scale • Intelligent storage • Resiliency in software only

13. Traditional Costs vs Cloud (no bandwidth) Cost Benefit Mostly from automation Intelligent sourcing Benefit from technology changes over time Admin Maintenance SW Economies of scale Use intelligent SLAs Competitive Differentiation Admin Maintenance SW Power Cooling Admin Maintenance SW Admin Maintenance Admin Maintenance Power Cooling Admin Maintenance SW Power Cooling Power Cooling Power Cooling The only way to accurately track cost changes in components Power Cooling Servers Servers Servers Servers Servers Servers Storage Storage Storage Storage Storage Storage Networking Networking Networking Networking Networking Networking Low cost Servers Cloud Initial Setup Storage ThinP Traditional Costs 1:50 Admin 1000VMs Aggressive concurrency

14. COST OPTIMIZATION EXAMPLES Purpose built scale-out product lines: example servers Extreme scale out datacenters with lean management Density optimized for the data center Shared infrastructure for accelerated service delivery HP Utility Ready Computing Service: www.hp.com/go/utilityreadycomputing

15. Time: how long does it take ? • Component lifetime is1/3 of DC expected lifetime. • At least 1 or 2 technology refreshes must be planned during the lifetime of the project. • The most frequent reason of financial model failure is the absence of MLU (Middle Life Upgrade) • B2T model: Business to Technology • HP: Interoperability, Planning. • According to existing trends: • 12 months to begin • 12-24 months to accumulate usage (utilization) • Utilization is what counts, so lack of utilization magnifies the apparent cost of the service

16. Service Requested Service Delivered Example Solution: HP CloudStart Industry’s most complete, turnkey cloud solutions From bare floor to cloud within 30 days, users can: • Request a compute service via a portal • Have service provided immediately • Use the service without worrying about security, management, etc • Scale or cancel the service • Get a regular report on consumption or chargeback * Based on typical duration time after hardware and software installation as well as consulting service terms and conditions

17. Know-how: the cloud ecosystem Customer Defined • Who has the know-how ? • Normal selling motion and purchasing motion is disturbed • New SLAs negotiated • “Moving to the cloud” competencies • Redefine competencies. Time element. • Learn to live in the new world where the service consumer knows more that the service seller…about the service ICT Enabler/ Provider Application Provider Application Infrastructure Service Technology Technology Provider Utility Carrier Defined Adapted from Gartner 2009

18. Where is the real know-how (examples) • Statistical multiplexing of VMs (place them where…, move them when…) • VMs versus bandwidth allocation techniques • Different sourcing mechanisms • Different sourcing mechanisms for bandwidth • Application transformation for Intelligent SLA creation • User control : the notion of VPC (Virtual Private Cloud) • SLA definition Cost contribution

19.

20. Competition and Content ? • Content • Standardization is a requirement for cloud. • If you can “process-describe” it then you might be able to “cloudify”. Otherwise you cannot. • Fight the tendency to define application hosting as “Software as a Service”. • Get ready for brokering • Burst to other clouds • Expand SLAs to other providers • Unique solutions from HP • Competition • Is there any competition in G Clouds ? • In what form ? • Co-opetition in agencies. • Comparison of cost models versus commercial offerings (see apps.gov) • There is nothing free (although it appears to be). • As you define “stricter” SLAs you move away from cloud into “utility computing”

21. Comparison of models You will be brokering IT Must use these… Business Your Customers… Who use these… But they have other options too… Hybrid Service Portfolio Internalprivate services Hostedservice providers Managedservice providers Cloudservice providers Networkservice providers

22. Designing based on “competition” 2 SUSTAINABLE Size Define your financials Define your Competition New <2 years Target Market Non Movable. Size to get Market Price for SLA New Old and movable To Cloud Size To get Price for SLA Movable Resistance To Move Non Movable Min size to get scale benefits Min size to be “competitive” Gov Market Total Market
