2008 Migration to Enterprise Cloud Computing

Migration to
Enterprise Cloud Computing
Bob Marcus

One Definition of Cloud Computing
 Cloud Computing describes information
technology (IT) resources with these properties:
 Hosted on a remote virtualized infrastructure
 Scalable deployment possible
 Accessed as services
 Support Internet protocols and interfaces
 Payments based on actual use of resources
 Enterprise Cloud Computing is the incorporation
of Cloud Computing resources into Enterprise IT

Enterprise Cloud Computing Challenge
 Cloud Computing has the potential to provide
major benefits to enterprises
 Cloud deployments are now following the
traditional life cycle for emerging technologies
e.g. over-hyped, push-back, ultimate use
 In the past, this life-cycle has produced mixed
results (e.g. SOA)
 In the current economic climate, it will be very
valuable to speed up successful deployments
 Challenge: Develop a new process for
migration to Enterprise Cloud Computing

Key Enterprise Cloud Computing Issues
 Standardizations Needed
 APIs between Cloud layers (e.g. PaaS and IaaS)
 Interoperability across Clouds
 Interoperability between public Clouds and enterprise systems
 Robust Cloud Operations
 Security of applications and data in public Clouds
 Availability, risk management, and SLAs for public Clouds
 Governance of services across public Clouds and the enterprise
 Implementation Guidelines
 Best practices for migrating appropriate applications to Cloud
environments
 Use cases and patterns for enterprise Cloud deployments
 Organizational support with the Enterprise for Cloud Computing
 Maturity of Enterprise Cloud Software and Services

Possible Enterprise Cloud Efforts
 Cloud Computing Industry Associations
(collaboration by suppliers and system integrators)
 Enterprise Cloud Computing User Groups
(interaction of suppliers, customers, standards groups)
 A Federal Open Cloud Initiative
(government initiative with industry and academia)
 InterCloud Interoperability coordination
(industry, multiple governments, standards groups)

Cloud Computing Layers
Downloadable Apps (e.g. Office Apps as a Service)
Environments and Interfaces (e.g. Desktops as a Service)
Applications (e.g. Software as a Service = SaaS)
Middleware and Data Services (e.g. Database as a Service)
Computing Hardware and Physical Storage
Resource Services (e.g. Infrastructure as a Service = IaaS)
Distributed Virtualization Services
Composite Applications(e.g. Workflow as a Service)
Develop, Deploy, and Run Services (e.g. Platform as a Service = PaaS)

APIs Between Cloud Layers
 What API standardizations are really needed
for portability in the near future e.g. API for
IaaS (CPUs, storage)?
 Are there existing deployed APIs that should
be the starting point of future standardization
activities?
 What should be the industry process for
defining and implementing these standards?

Interoperability across Clouds
 What are the requirements for Cloud to Cloud
interoperability at each level (e.g IaaS, PaaS,
and SaaS) in the next few years?
 What are the technical and non-technical (e.g.
business, legal) standardizations needed to
provide the required interoperability?
 What should be the process for defining and
implementing international InterCloud standards?

Interoperability across Clouds and Enterprise
 How can public Clouds be used to extend
enterprise systems (e.g. to handle spikes in
resource requirements)?
 How can enterprise applications be
incrementally migrated to Cloud platforms?
 How can enterprise policies and governance
be extended to include Cloud deployments?

Security of Applications and Data
 How can the security of application and data
be guaranteed in Cloud deployments?
 Which current enterprise applications and data
can be safely deployed on public Clouds?
 Can virtual private Clouds become an equally
secure alternative to internal Clouds?

Availability, Risk, and SLAs
 What are the past problems with public Clouds
and how can customers be sure that these
problems won’t occur in the future?
 What sort of SLAs should user expect for
Cloud deployments?
 Are there documented ways to mitigate the risk
of Cloud deployments?

Governance and Management for Clouds
 How can enterprises provide policy
enforcement on Cloud deployments?
 Are there system management tools that work
across Clouds and enterprise systems?
 How are costs allocated for shared resources
across enterprise organizations?

Best Practices for Migration
 How can an enterprise determine which
applications should remain internal?
 How should an enterprise decide whether to
use SaaS leasing, PaaS tools, or IaaS
foundation to deploy applications?
 Are there documented methods for SaaS,
PaaS, and IaaS deployments?

Use Cases and Patterns
 Which enterprise applications and processes
are most suitable for Cloud deployments?
 What are the success stories for Cloud
deployments by enterprises?
 Are there documented design patterns for
PaaS and IaaS deployments?

Organizational Support for Cloud Computing
 What new enterprise organizational structure
and roles (if any) are needed to handle Cloud
Computing?
 What is the relationship to SOA organizations
(e.g. Centers of Excellence?
 What should be the role of an Enterprise
Cloud Computing Group with members from
multiple enterprises, industry, government, and
standards groups?

Enterprise Cloud Software and Services
 What software and/or services are available for
enterprise Cloud Computing?
 What are the benefits of these software/services
to enterprises?
 Are there referencible examples of successful
deployments using these software/services?
 What are the key lessons learned from past
efforts that can improve future deployments?
 What are the goals and direction for Cloud
software/services providers in the future?
