OnPremisesSysteme

OnPremisesSysteme refers to information technology systems that are deployed and operated within an organization's own facilities, with hardware and software hosted on-site rather than in a public cloud or external data center. The term encompasses servers, storage, networking gear, databases, and applications installed and managed locally.

In practice, on-premises systems are typically owned and controlled by the organization, with data resident inside its networks. They may leverage virtualization and dedicated or shared storage, and require robust backup, disaster recovery, and security controls. Integration with other systems is achieved through internal networks and standardized interfaces, while hybrid configurations connect on-premises components to cloud services when needed.

Deployment is usually capital expenditure, covering procurement, installation, and ongoing maintenance, firmware updates, and hardware refresh cycles. Scalability depends on adding hardware and reorganizing resources, which can entail longer procurement timelines compared with cloud expansion.

Benefits include greater control over data and security, customization to regulatory needs, and predictable network performance for latency-sensitive workloads. Drawbacks include higher up-front costs, maintenance burden, risk of underutilized assets, and the need for specialized staff and skill sets.

Security and compliance considerations emphasize physical security, access management, patching, and network segmentation. Organisations may adopt a hybrid approach to combine on-premises governance with cloud flexibility, while ensuring data sovereignty and alignment with governance frameworks.
