Introduction

What is Cloud Computing? Cloud Computing is one of the hype topics in the high-tech industry

today. Almost every IT company offers some kind of cloud product or services and almost

every IT expert uses a different definition of the term Cloud Computing. For a typical private

end-user, Cloud Computing means to use a Web-based service, for instance online services

for data storage, email, word-processing, spreadsheets, collaboration, file conversation, socialmedia, etc. There is no magic behind these Web services, other than the fact that the end-user

does not need to deploy or install dedicated applications on their home PC system anymore.

The only prerequisite is the existence of a working internet connection. Most of the mentioned

services are free and for others, end-customers pay a monthly fee, usually on a per user basis.

The general concept of Cloud Computing from a private end-users point of view is:

To plug into the internet from anywhere access processing, applications, and data services

whenever needed

To only pay for what is used or needed

However, private cloud usage is only one aspect of the overall cloud story. Companies have

realized that Cloud Computing might be a good avenue to reduce internal IT costs by spending

less money on software licenses, hardware, storage, training, and the needed maintenance of

the mentioned areas. Small and medium sized enterprises might especially gain large

advantages by using a cloud-based IT approach instead of building internal datacenters. An

outsourcing model can help to extend IT services step by step depending on the growth of the

individual business.

This white paper provides a general overview of the term Cloud Computing from an enterprise

point of view. In addition, the topic of Enterprise Resource Planning (ERP) in the cloud is

covered with a dedicated focus on the SAP ERP stack deployed on cloud technology

components from Oracle.
