name: NAAS
full_form: Network 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: Network as a Service (NAAS) is a cloud computing model that provides virtualized network services over the internet. Users can access and manage network resources remotely through NAAS. In 3GPP, NAAS involves hosting network functions in a shared environment, potentially outside the control of the Communication Service Provider (CSP).
explanation: NAAS is explicitly described as a cloud computing model that delivers virtualized network services. Its characteristics, such as remote access and shared hosting environments, align with the core principles of cloud computing.
