This encompasses the fundamental elements of cloud IT, generally offering access to network functions, computers (virtual or dedicated hardware), and data memory. Infrastructure as a service offers a high level of flexibility and administrative control over your IT resources.
In this case, companies no longer need to manage the underlying infrastructure (generally hardware and operating systems). Because companies only have to concentrate on making their applications available and managing them, more efficient work is possible. The customer no longer has to carry out resource procurement, capacity planning, software maintenance, patching, and other tasks.
Thanks to SaaS, companies no longer need to worry about service maintenance or how the underlying infrastructure is managed. They can concentrate exclusively on using the software. In this model, the service customer saves on some of the purchase and operating costs. All of the IT administration and other services such as maintenance work and software updates, including all admin tasks, are performed for the customer. For this purpose, the IT infrastructure is outsourced, and service customers can concentrate on their core business.
