Rupert Chapman, cloud specialist at PA Consulting Group, has been quoted in the Financial Times 'The Connected Business' special report. Rupert looks at Cloud computing and the various descriptions of the services it offers. Rupert looks at what technical terms such as infrastructure-as-a-service, platform-as-a-service and software-as-a-service really mean.
Rupert says: “There are real differences, but there is also a degree of marketing spin. They describe the levels of service on offer.”
Rupert goes on to explain that infrastructure-as-a-service (IaaS) involves the customer paying for off-site use of basic hardware and equipment – servers, network equipment, database storage from the provider: “I get access to very cheap shared machines and can put my own operating system and applications on top, so I have a degree of control.”
Commenting on software-as-a-service (SaaS) Rupert says: “All I need is an internet browser and I can log in from home, the office or the coffee shop. Everything is looked after by the cloud provider.”
Rupert goes on to conclude: “Clients tend to forget about the labels. These are terms that will stay in the IT world. Most business users don’t care and are probably turned off by them.”
