name: IAAS
full_form: Infrastructure As A Service
context: Large tier 1 CSPs typically own their own data centres and will operate their own virtualisation host infrastructure, even if the management of that infrastructure may be outsourced to 3rd parties. However, smaller VNOs will likely want to consider an IAAS or NAAS model. In these scenarios sensitive personal data belong to subscriber and cryptographic (e.g. keys and algorithms) are now being stored in a 3rd party shared environment which is not within their control. Whereas, a tier 1 CSP has tight control over where their data centres are located and therefore where their sensitive data is located (and in turn who has access to that data), in a tenant IAAS or NAAS this is more difficult to control. 3GPP functions need to be securable both where CSPs have tight control over NF host environment (including location) and where they do not.
description: IAAS (Infrastructure as a Service) is a cloud computing model where virtualized computing resources like servers, storage, and networking are provided on demand as a service. This allows organizations to access and manage these resources without the need for physical hardware or on-premises infrastructure.
explanation: The description clearly defines IAAS as a specific type of cloud computing model that focuses on providing infrastructure as a service, making it distinct from other network function categories.
