Clouds – What It Is?

1.

Again - Buzzword Bingo

100 different definitions of Cloud Computing – depending on the marketing strategy of the vendor issueing the statement

Thus derived terms are build on an unstable foundation

Sometimes just talking for the sake of talking aboutCloud Architecture, Cloud Taxonomy, Cloud This and That

Attention – behind all the marketing hype and the race for the coolest buzzword there is a simple, sustainable

and sensible idea!4 |

Professional Buzzword Bingo !

So What Is It?

Clouds make IT ressources dynamic

Like the power grid, you do not know how and where IT ressources are produced in Clouds

Like the power grid, you do have access to as much IT ressources as you request – anytime, anywhere in Clouds

Cloud Computing is „just as much IT as I currently need out of the socket

and I don´t have to care where it came from“

Cloud Concepts Top Down

1. Original Idea:a computation problem is to by dynamically distributed across available resources and solved by optimized (for time, cost, …)‘ parallel processing. then processed in the parallel. The Cloud controls infrastructure, parallelization and reassembly of partial results as well as optimizing the whole process according to given parameters

2. Realitycurrently there is no kernel (Master Control Program, Skynet, …) with that much power or intelligence

3. Downsized IdeaIT ressources as we know them (single servers, services or programs) are made available dynamically

Clouds the Next Step after

Virtualization

Virtualization – Every Day Business, But Yet a Dream

Goal 1: Increase utilization of internal IT resources from under 8% to roughly 15%

Goal 2: Speed up the delivery of standardized building blocks in order to scale parts of the known IT

Today: better hardware use, better backup concepts, faster deployment and more clean installations

Dream: reducing hardware, standardized IT cheaper administration

What Virtualization Cannot Do!

Guarantee SLAs while using the least hardware possible

Cover temporary needs

Scale services instead of scaling servers

Support dynamic concepts on programming level

10 |

Clouds Need Virtualization

The foundation for distributed omputing is the capability of dynamically scaling hardware – simulating hardware (?!)

The first level of any Cloud architecture is a virtualization layer

Any Cloud Architecture requires at least one management layer for• Service management• Automated scaling• Automated change in infrastructure• Distributed computing• …

11 |

Clouds Enhance the Concept of Virtualization

Due to the massively increased number of available hardware components in a Cloud, living up to SLAs becomes statistically very probable

By writing programs for the Cloud services will actually be dynamic

Cloud management will automatically adjust infrastructure according to use and dependencies

Business Case

of Clouds3.

13 |

Very Simple…

<10% of available hardware is actually „used“ in any corporation

Available hardware does consume 100% of overhead cost (power, cooling, facility space,maintenance, …)

The Business Case of Clouds is to reduce necessary hardware investment by 90%,

get rid of infrastructure maintenance cost and minimize administration efforts

14 |

Where Can We Use It Today?

To cover temporary need for large scale computationa power (e.g. simulations, …)

To cover short term need for development and test systems

Public services (e.g. simple wen applications, information services, …)

Web 2.0 engagements

What Are the Current Challanges?

Security• Dynami access to internal data• Managing identities, rols and users• Shared use of infrastrucure

Trust• Location and regulatory environment• Industrial espionage• Dependency on Cloud provider

Internal Procedures• Investment budgets are ties to projects• Operating budgets are tied to projects• Centrlized administration of business alignemnt
