As a service

*aaS is an acronym for as a service, and refers to something being presented to a consumer to a customer, either internal or external, as a service, always in the context of cloud computing.. As a Service, or XaaS 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 users 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 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.
Because aaS services are generally based on open source projects with little to no licensing costs, ideally require little to no human intervention to perform their tasks/roles, could possibly be scaled out on demand to the full physical resource capacity of an entire datacenter region, are maintained and supported internally by the cloud provider, and use resources that are expendable for reuse by other IaaS tasks and services, XaaS services represent a large cost savings over traditional vendor-provided infrastructure and server based equivalencies, which often include vendor-specific lock-in features and imposed product feature set limitations which focus more around supporting that vendor's product portfolio and feature roadmap than similar open source projects.
