With this service, subscribers are limited to access and use of the software only. The provider handles everything else: managing and controlling the network, servers, operating systems, storage, virtualization, data, middleware, and even individual application capabilities.

Within this environment, users run an operating system and provision the processing, storage, networks, and other fundamental computing resources needed to run software on the cloud infrastructure.<\/li>\n\n\n\n<li>With IaaS, the subscriber may also have limited control of select networking components (e.g., host firewalls). Some providers will also offer services such as monitoring, automation, security, load balancing, and storage resiliency.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Anything as a Service (XaaS)<\/strong>\n<ul class=\"wp-block-list\">\n<li>There are several other service models defined as XaaS, which do not strictly fit in the above three categories.
