1. Introduction to Cloud Computing

• How did we get here - 
  • From application hosting to SaaS to public & private cloud
• Cloud definition
  • Chose your flavor: IaaS, PaaS, SaaS
• Typical cloud usage scenarios
  • SaaS vs. traditional enterprise computing
  • The programmable Web: an API in the cloud

2. Cloud Migration

• Better utilization through resource virtualization
• Cloud management for elasticity: automated, on-demand provisioning of resources
• Evolving the economy of scale through shared infrastructure and applications
• Cloud benefits and challenges

3. IaaS (Infrastructure as a Service)

• IaaS architecture and key features
• Who are the major IaaS providers?
  • Microsoft Azure
    • Web Roles & Worker Roles
    • Scalability, load balancing, fail over
  • Amazon Web Services (AWS)
    • Elastic Compute Cloud (EC2) & Amazon Machine Images (AMI)
    • IaaS+: AWS Application Services and Marketplace
    • Regions & Availability Zones
    • Networking & security
    • Monitoring, Auto Scaling, & Load Balancing
    • Building scalable and fault-tolerant applications
    • How to protect yourself from outages
    • Management interfaces
• Private & hybrid cloud
  • Drivers & challenges
• Defining the requirements
• A Methodology for building a private cloud
• How to manage the private cloud
• Who can help: vendor overview
  • VMware
  • Abiquo
  • Amazon Virtual Private Cloud
• Hybrid clouds
  • Use cases
  • Product example: Eucalyptus
• How to select a private cloud model

4. PaaS (Platform as a Service)

• PaaS defined
• A complete PaaS stack
  • Where to draw the line: IasS+ or pure-PaaS or custom-SaaS?
  • What functionality do we need to build applications for the cloud?
• Multi-Tenancy
  • What is a multi-tenant system?
  • Evolving the economy of scale
  • Customizing the application for a tenant
  • Considerations for multi-tenant applications:

    Stability, SLA, legal & regulatory, security, maintenance, 3rd-party components

• Who are the major PaaS providers?
  • Microsoft Azure
  • Google App Engine
  • Force.com
• Outlook: the future of PaaS

5. SaaS (Software as a Service)

• What is SaaS?
• Some examples.

6. Cloud Architecture

• Service Oriented Architecture (SOA)
  • Service Layer Model & the concept of loose coupling
  • SOA + Event Driven Architecture (EDA) = e-SOA
  • What is REST and why is it important for the cloud?
• Synergy of SOA and Cloud - the industry view
• SOA / SaaS synergy
• SOA / PaaS synergy
  • Approaches to meet demand
  • Applying SOA principles to the cloud: loose coupling, encapsulation, asynchronous services
  • Building multi-tenancy applications based on SOA
  • Migrating legacy systems into the cloud
• SOA / IaaS synergy
  • Service-Oriented Infrastructure (SOI)
  • Service virtualization vs. server virtualization
  • Automated, on-demand resource provisioning

7. Cloud Integration

• The need for cloud integration and its challenges
• How SOA can help: focus on integration
  • From application integration to Service Oriented Integration (SOI)
• The need for (inter)mediation
  • Mediation functionality
• Enterprise Service Bus (ESB) reference architectures
• What are the particular requirements for cloud integration?
  • From ESB to “Internet Service Bus”
• Product Examples:
  • Windows Azure AppFabric
  • IBM Cast Iron
  • Fiorano

8. Standards and Open Source Software

• Cloud standards
  • Portability & interoperability: problem statement
  • Distributed Management Task Force, Inc. (DMTF)
    • Open Virtualization Format (OVF)
    • Open Cloud Standards Incubator
  • Apache Libcloud
  • Open Source Software (OSS)
    • OpenStack

9. Cloud Security

• The evolution to Cloud Security
  • From traditional Web applications to SOA to Cloud
  • Public cloud vs. on-premise datacenter
• Cloud security is a multi-dimensional problem
  • Dimension 1: IaaS, PaaS, SaaS
  • Dimension 2: Network, VM, application, data
  • Dimension 3: CSP, tenant
• Identity, Entitlement & Access Management (IdEA)
  • Authentication & Access Control
  • SAML, XACML, and Policy Enforcement Point (PEP)
  • Security across on-premise systems & multiple Clouds
• Cloud Security Alliance standards
  • Cloud Controls Matrix, Consensus Assessments Initiative, Cloud Audit, Cloud Trust Protocol
  • Security, Trust, and Assurance Registry

10. Governance for Cloud-Based Services

• Business vs. IT vs. EA vs. SOA vs. Cloud Governance
• Why SOA governance can (should) be the basis for Cloud governance
• SOA governance frameworks, standards, technologies
  • Open Group’s Service Integration Maturity Model (OSIMM)
  • Open Group SOA Governance Reference Model (SGRM)
  • SOA Governance Vitality Method (SGVM)
• Cloud governance
  • Similarities and differences to SOA governance
  • Delineating responsibilities: cloud provider vs. cloud customer
  • Switching cloud providers – the worst case test for your governance
• A Cloud governance methodology
• Technologies for implementing governance

11.Outlook and Conclusions

• Outlook and usage for cloud computing
