aaS, or XaaS, is an acronym for as a service (e.g., anything as a service), and refers to something being presented to a customer, either internal or external, as a service.[1] As a Service offerings provide endpoints for customers/consumers to interface with which are usually API driven, but can commonly be controlled via a web console in a user's web browser.
Internally these often complex systems generally possess a high degree of internal automation which generally provide varying levels of fault tolerance and resiliency, the ability to scale up/down in or out to meet capacity and performance requirements of the workloads submitted to the service by its users/consumers, and are usually intended to operate their day to day functions without the need for human intervention. IaaS (Infrastructure as a service) features most commonly included in this automation package are compute, storage, network, telemetry, and logging/accountability features, but most IaaS components owe some portion of their workload to these services. The current cloud computing ecosystem contains multiple cloud providers, each with their own menu of these services for their customers to consume on-demand or in some cases even with pre-scoped capacity agreements.[2]
(X)aaS services have the following features:
- They are based on open source projects with little to no licensing costs [citation needed]
- Require little to no human intervention to perform their tasks/roles [citation needed]
- Could be scaled up or down depending on level / volume needed [citation needed]
- Maintained and supported internally by the cloud provider [citation needed]
- Use resources that are expendable for reuse by other IaaS tasks and services [citation needed]
Using XaaS services can offer a large cost savings [citation needed] over traditional vendor-provided infrastructure and server based equivalencies. When deciding on XaaS, one has to consider vendor-specific lock-in features which can be more limited than other similar open source projects. [citation needed]
