Workloaded security models are ways of protecting applications, services, and capabilities that run on a cloud resource. Virtual machines, databases, containers, and applications are all considered cloud workloads. There are different types of cloud deployment models, such as public, private, hybrid, and multicloud. Depending on the deployment model, the cloud workload security can vary in terms of responsibility, visibility, and control.
Infrastructure as a service (IaaS) is a cloud deployment model where the cloud provider offers the basic computing infrastructure, such as servers, storage, and networking, as a service. The customer is responsible for installing, configuring, and managing the operating systems, applications, and security of the workloads that run on the cloud infrastructure. IaaS provides the customer with more flexibility and control over the workload security, but also more complexity and overhead.
On-premises is a deployment model where the customer owns and operates the entire IT infrastructure, including the hardware, software, and security. The customer has full responsibility and control over the workload security, but also the highest cost and maintenance. On-premises deployment can offer more security and compliance than cloud deployment, depending on the customer’s security posture and practices.
