Workload security models refer to the ways of protecting applications, services, and capabilities that run on a cloud resource. There are different types of cloud deployment models, such as public, private, hybrid, and multicloud, and different types of cloud service models, such as IaaS, PaaS, and SaaS. However, these are not workload security models, but rather ways of describing the cloud environment and the level of abstraction. Workload security models are more focused on the location and ownership of the workloads, and how they are secured. The two main workload security models are off-premises and on-premises. Off-premises workload security model means that the workloads are hosted and managed by a third-party cloud service provider, such as AWS, Azure, or GCP. The cloud service provider is responsible for the security of the underlying infrastructure, such as the physical servers, network devices, storage systems, and hypervisors. The customer is responsible for the security of the workloads themselves, such as the guest operating systems, applications, data, and users. The customer can use various tools and techniques to secure their workloads, such as encryption, firewalls, identity and access management, vulnerability scanning, and logging and monitoring. On-premises workload security model means that the workloads are hosted and managed by the customer on their own data center or private cloud. The customer is responsible for the security of both the infrastructure and the workloads, and has full control and visibility over them. The customer can use similar tools and techniques as the off-premises model, but also has to deal with the physical security, network security, and compliance requirements of their own environment.
