STAATSKOERANT, 31 Mei 2024 No. 50741   139 can be rapidly provisioned and released with minimal management effort or service provider interaction”. 13. CLOUD COMPUTING SERVICE MODELS Cloud services are primarily provisioned using three traditional models – IaaS, PaaS, and SaaS. These service delivery models differ in how responsibility and accountability are shared between the cloud service provider and the consumer of the cloud-provided services. 13.1. Software as a Service (SaaS) In the SaaS model, cloud users directly access the applications provided by the cloud provider. This model offers the convenience of not having to manage the underlying infrastructure or the capabilities of the applications, allowing users to focus solely on utilizing the software. 13.2. Platform as a Service (PaaS) PaaS provides users with a more structured platform to deploy their own applications and services. Users can rely on the programming languages and additional tools provided by the cloud provider to develop, deploy, and manage applications without handling the underlying infrastructure. 13.3. Infrastructure as a Service (IaaS) IaaS offers fundamental computing resources such as processing power, storage, and networks to cloud users. This model enables users to leverage these resources through their own implementation of virtualization capabilities, providing the flexibility to manage and control the infrastructure according to their specific needs. 14. CLOUD DEPLOYMENT MODELS Cloud services are provisioned using the following deployment models. Each of these has advantages, disadvantages and constraints. 14.1. Private cloud The cloud infrastructure is provisioned for exclusive use by a single organisation comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organisation, a third party, or some combination of them, and it may exist on or off premises. 17 This gazette is also available free online at www.gpwonline.co.za
