The document discusses cloud computing services and their impact on data centers. It begins with definitions of key cloud computing concepts like clusters, grids, service-oriented architecture, and virtual data centers. It then outlines various cloud services like SaaS, PaaS, and DCaaS. The document considers who should and should not use cloud services based on factors like predictable demand. It profiles several major companies involved in cloud computing and their offerings. It also examines how cloud services affect reliability and what they may mean for data centers, which could see a shift to fewer, larger, and hardened facilities.

• How Cloud Services affect reliability
• What does it mean for the Data Center
• Questions

3. “The rise of the cloud is more than just another
platform shift that gets geeks excited. It will
undoubtedly transform the IT industry, but it will
also profoundly change the way people work and
companies operate.”
—The Economist, “Let it Rise,” 10/3/08

4. Definitions
• Cluster
• Compute (HPC)
• High Availability
• Grid
• Smart Grid
• SOA (services)
• SaaS
A collection of services and
• Cloud
supporting systems operating as a
single resource.
• VDC

5. Definitions
• Cluster
• Compute (HPC)
• High Availability
• Grid A geographically distributed
• Smart Grid collection of services and
• SOA (services) supporting systems dedicated to
• SaaS
a community of users, designed
• Cloud
and configured to operate as a
single resource.
• VDC

6. Definitions
• Cluster
• Compute (HPC) Service Oriented Architecture:
• High Availability A set of Interfaces (APIs) built on
• Grid a dynamic IT infrastructure
• Smart Grid which can automatically adapt to
• SOA (services) changing needs without
• SaaS
disruptions to running
• Cloud
applications.
• VDC

7. Definitions
• Cluster
The Cloud
• Compute (HPC)
• High Availability
• Grid
• Smart Grid
Applications, data, compute, and
• SOA (services)
storage resources are managed
• SaaS as an abstraction. This
• Cloud collection of virtualized services is
• VDC the cloud.

8. Definitions
• Cluster
• Compute (HPC) Virtual Data Center
• High Availability
• Grid
• Smart Grid
• SOA (services)
• SaaS Virtual Data Center, provides
• Cloud
infrastructure on demand with little
• VDC
or no capital expense.

9. Services
•Software As A Service (SaaS)
•Processing As A Service (PaaS)
•Storage As A Service (SaaS)
•Information Technology As A Service (ITaaS)
•Data Center As A Service (DCaaS)

10. Services
•Software As A Service (SaaS)
•Processing As A Service (PaaS)
•Storage As A Service (SaaS)
•Information Technology As A Service (ITaaS)
•Data Center As A Service (DCaaS)

11. “In this architecture, the data is mostly resident on
servers ‘somewhere on the Internet’ and the
application runs on both the ‘cloud servers’ and
the user’s browser.”
—Eric Schmidt in ‘Information Factories’,
by G. Gilder

12. Who should use Cloud Services?
Yes No
Is IT demand reasonably constant? Data Center Cloud
Are growth predictions accurate? Data Center Cloud
Is scaling predictable and planned? Data Center Cloud
Is your user-base local? Data Center Cloud
Is infrastructure agility a core strength? Data Center Cloud

22. How Cloud Services affect reliability
• Customization is limited, simplifying and reducing the number of interface
dependencies. Dependencies become explicit.
• Applications must be designed to take advantage of cloud service fault
tolerance. Current services may not support your application architecture.
• Support for regulatory DR and RTO requirements?
• Internal SLAs covered by external customer service?
• “Where is my data?”, logically and geographically?
• Connectivity becomes critical.

23. What does it mean for the Data Center?
• An open question.
• Data Center on demand.
• Little or no capital investment.
• Services will be additive.
• Privacy concerns, network bandwidth, and
political hurdles will slow adoption as the
segment matures.
• Ultimately, cloud services may drive a
move to fewer, larger and hardened data
centers.
