Chapter 4: Infrastructure as a Service (IaaS)

MANY COMPANIES THAT DEPLOY applications to the cloud will need a specific platform, such as Windows, .NET, and Microsoft SQL Server, or Linux, Perl, and MySQL. Utilizing a platform as a service (PaaS) solution eliminates the company’s need to administer the operating system and supporting software. Other companies, because of security needs or a desire to manage all resources, turn to infrastructure as a service (IaaS) providers. An IaaS provider makes all of the computing hardware resources available, and the customers, in turn, are responsible for installing and managing the systems, which they can normally do, for the most part, over the Internet.
