Cloud Computing – A clear promise
Use ICT resource services just when you need them. Cloud computing makes this possible by cutting costs and increasing flexibility in companies.
Facts, data, figures
- According to a study by consultancy A.T. Kearney, companies using cloud computing can cut their IT costs by up to 25 percent.
- An IDC forecast predicts that worldwide investment in cloud-based Internet services will increase from US$ 17.4 billion in 2009 to US$ 44.2 billion in 2013. This corresponds to an average annual growth of 26 percent. Their share of total IT expenditure during this period will grow from 5 to 10 percent. According to this forecast, cloud services will achieve a growth rate six times higher than traditional IT offerings.
- The market for servers specially tailored to cloud computing is set to grow from almost US$ 8 billion to around US$ 12.6 billion by 2014, predicts an IDC forecast. Server systems for private clouds will have by far the largest share at US$ 11.8 billion.
Technology
- Based on the definition of the American standardization authority NIST, T-Systems understands cloud computing as the hiring of infrastructure, software and bandwidths under defined service conditions. These components can be adapted daily to the customer’s needs and can be provided with the highest availability and security. The user companies receive end-to-end Service Level Agreements and are billed according to service consumption.
- Two CC definitions from market research companies: According to Gartner, CC is characterized by the “provision of scalable IT services via the Internet for a potentially large number of external customers”. Forrester Research defines CC as a "pool of abstracted, highly scalable, managed IT infrastructure capable of hosting end customer applications and billed by consumption."
Cloud Computing (CC) is on the up. Starting from a market share of US$ 17.4 billion in 2009, IDC reckons that cloud computing will reach a market volume of US$ 44.2 billion as early as 2013. It will hold a 10 percent share of the total IT service market by 2013.
