!!! Overview [{$pagename}] ([IaaS]) is a [Cloud Services Model] which provides self-service models for assessing, [monitoring], and managing remote [Data Center] infrastructures, such as compute ([Virtual Machine] or bare metal), [Data Store Service], [networking|Network], and [Network devices] (e.g. firewalls). With [{$pagename}] instead of having to purchase [hardware] outright, users can purchase [{$pagename}] based on consumption, similar to electricity or other utility billing. [{$pagename}] users are responsible for managing [applications], [data], runtime, [middleware], and [Operating Systems]. Unlike when using to [Software as a Service] and [Platform as a Service], [Cloud Service Providers] manage [Virtualization], [servers], [disks], [DataStores], and [networks]. Many [{$pagename}] providers now offer [databases], messaging [queues], and other services above the virtualization layer as well. Some tech analysts draw a distinction here and use the [{$pagename}] moniker for these other options. What users gain with [IaaS] is infrastructure on top of which they can install any required platform. Users are responsible for updating these if new [versions] are released. !!
