IaaS
Infrastructure as a Service supplies computing, storage and networks. The operating system and the company’s own applications remain the team’s tasks.
What does IaaS mean?
Infrastructure as a Service (IaaS) is a cloud service model for basic IT resources such as computing capacity, storage and networks. A company can run its own operating systems and applications on them. The provider manages the underlying cloud infrastructure; the consuming team controls the operating system, deployed applications and its allocated storage resources in particular.
A fictional software company runs its customer portal on a virtual machine from an IaaS service. The team installs the application and takes responsibility for tasks including updates to its own operating system and software. It also defines how application data is backed up and restored. An available virtual machine does not by itself demonstrate a working recovery of the portal.
With PaaS, the provider also supplies a platform for running supported applications. IaaS leaves more technical design to the team. Any additional agreed services need to be checked against the specific offering.
