Abstract:

The ability for enterprise IT to effectively leverage cloud computing means a
transformational change in the way that IT thinks about and executes system
design, development, and implementation. For many organizations, there is still
much confusion around technical approaches, including the proper use of open
systems technology. Those who sell highly proprietary technology are creating
both hype and confusion. In many instances, the proper approaches get pushed
to the back of the room.

This presentation will take the mystery out of both cloud computing, and the
proper fit and function of open systems technology when building a cloud
computing strategy. Instead of mere theory, this session will guide you through a
step-by-step process for understanding your own requirements, creating the
business cases, and selecting the right technology that will lead your enterprise
to success in the cloud.

The fight begins…


…and, things are getting crowded.


“Inside Baseball”

• Watch…
the number of offerings out there, and the quality of the
distributions.
the hype, what’s real versus perception.
• Understand…
that rigorous testing is required, before implementation.
your own security requirements.
that you may be mixing and matching technology.
the roadmap for each product.
the near-term and long-term costs.


Why You Should Care


Most Open System Cloud-Based Systems are
Lacking Architecture


The results:
• Inefficient utilization of resources.
• Resource saturation.
• Lack of elasticity and scalability.
• Lack of security and governance.
• Frequent outages.
• Bad or no tenant management.
• Other very bad things.


Common Mistakes

• Not understanding how to make architectures
scale.
• Not dealing with tenant management issues.
• Not understanding that security is systemic.
• Not understanding the proper use of services.
• Tossing technology at the problem.
• Listening to the wrong people.
• Managing-by-magazine.


The Multitenant Thing
• No two multitenant
architectures are alike.
• Needs to be effective in the
context of the problem.
• Needs to leverage best
architecture practices.
• Needs to practice isolation and
protection.

“With a multitenant architecture, a software application is
designed to virtually partition its data and configuration so
that each client organization works with a customized virtual
application instance.”

How You Should Proceed


IaaS Building Blocks
This is a logical framework for IaaS and all of these components need to exist. Use this as a
framework of understanding to evaluate the core components of an open IaaS product. For each area
identified, there are dozens of requirements that must be defined-

Monitoring and Management Services
Management & Service Governance

Use-Based Accounting Provisioning Tenant Management
Security & Identity
