4. Everything as a Service
HP's Goal: Population Increase that gets benefit
from the information economy
Delivery of:
1. Infrastructure as a Service (IaaS)
2. Platforms as a Service (PaaS)
3. Software as a Service (SaaS)

6. Infrastructure as a Service
Technologies for servers, storage, networking,
IT management
(a) Computing Services
(b) Storage Services
(a) Scalable Computing Services
Requirement: Ability to scale server configurations
Development: Coordination Framework
→ Minimized need for global information exchange
6

7. Infrastructure as a Service
(b) Scalable Storage Service
Challenges:
(a) Reliability (b) Scalability (c) Cost-effectiveness

8. Infrastructure as a Service
(b) Scalable Storage Service
Challenges:
(a) Reliability (b) Scalability (c) Cost-effectiveness
Reliability
Data Replication!

9. Platform as a Service
Technologies for an Infrastructure:
→ Security, scalability, QoS
Requirement: Offer service providers to users
→ illusion of unique, secure infrastructure
Flexibility → Scalability of Resource use
BUT: Service providers → minimize scalability
1. Cost Maintenance
2. Runaway service Elimination
3. Deal with Virus-infected Service
9

10. Platform as a Service
Ensure for Cloud Services:
1. Security & Performance Isolation
2. Data & Sensitive Information Protection
3. Performance Guarantees Providing
10

11. Cell as a Service
Cell: VMs & Storage Volumes & Subnets
– with their corresponding attributes
Subnets:

Implemented as Virtual Overlay Networks

No special hardware

Packets are forwarded directly to the destination
11

12. Software as a Service
HP's Goal: → Develop models & technologies
→ Support the use of mobile devices
→ Capture collective intelligence
Projects

ePrint: No barriers of distance and connectivity

Rankr: Automatic derive rank ordering

i-Catcher: Increase of attention devoted to content

Watercooler: Better filtering for sharing & finding info

13. Conclusions
Huge Progress in Information Technology!
Challenging Problems:
1. Secure services, data, infrastructure from attack
2. Ensure the privacy of personal data
3. Services Availability despite of HW/SW failures
4. Performance must be predictable
