4. Cloud Computing: Main Objectives
Understanding business opportunities
• Faster time-to-market, and cost-effective innovation processes
• Dynamic (trans-)formation of open service and business networks
• Leveraging the participation Web and mass programming
Internet-scale service computing
• Provide and consume sophisticated infrastructure, platforms and business
applications as modular (Web) services
• Disrupt traditional industries and offer rich, highly dynamic experiences
Enterprise-grade systems management
• Under-utilized server resources waste computing power
and energy
• Over-utilized servers cause interruption or degradation of service levels

9. Landscape as a Service (LaaS)
LaaS offers fast and easy provisioning of multiple interelated Cloud components
 Goal: Cloud Computing system that allows coordinated provisioning of multiple,
disjoint and complete system landscapes
 Therefore images containing the different components/systems of the landscape
are parameterized and instantiated
 Also relations and constraints between the components of a landscape are
considered during image construction and instantiation and inside the
landscape/cloud controller
 The landscape provision service must allow for altering of the system landscape
setup to satisfy changing customer needs
 Typical use cases related to the altering of a system landscape include
• Adding additional systems to overcome high loads or extend the functionality
• Replace systems inside the landscape
• Remove systems from the landscape

11. SAP LaaS
 In this Use Case comprehensive SAP system landscapes shall be provided
• basically for test and development
• on demand to a customer as a self-service in a LaaS fashion
• under consideration of relations and constraints inside the system landscape
 Constraints given by a SAP system landscape
• can be implemented by configuring images accordingly as well as by enforcing
constraints inside the controller of the landscape provisioning system
• During image definition specific constraints like f.i. transports between SAP
systems (DTP/DQP-landscape) can be predefined
• In a landscape/cloud controller the instanciation sequence of SAP systems can
be policed f.i.

15. LaaS – Open Issues and Research Questions
 Open Issues:
• What about the data?
 Research Questions:
• Modeling Language for Cloud services, their configuration and relations
• Lightweight but powerful execution engine
• Other useful application scenarios
 Extensions:
• Management of Federate Clouds
• Cloud architecture pattern support
• (Framework for other research threads at eOrg)

18. Research Agenda
for the European Cloud Community
 Main Recommendations:
• R1: EC should stimulate research and technological development
• R2: EC together with Member States should set up the right regulatory
framework to facilitate the uptake of Cloud computing
 Additional Recommendations:
• AR1: The EU needs large scale research and experimentation test beds
• AR2: The EC together with industrial and public stakeholders should develop
joint programmes encourage expert collaboration groups
• AR3: The EC should encourage the development and production of (a) Cloud
interoperation standards (b) an open source reference implementation
• AR4: The EC should promote the European leadership position in software
through commercially relevant open source approaches

19. Our Derived Personal Cloud Trends for 2010
 Security: Rationalization of security discussion
 Ecosystem: Big IT companies will get more into focus
 Desktop as a Service: Thin clients+appliances+OS support
 Standardization: The battle goes into the final rounds
 SLAs: Establishment of useful SLA models
 Other candidates:
• Pricing: model evolution, e.g. spot markets
• Federation of heterogeneous Cloud infrastructures: distributed VPDC
