While both the hardware and software versions of Cisco Secure Workload provide the same core security capabilities, they differ significantly in how they are hosted and managed. The table below outlines the key technical distinctions between these two deployment models.

Table 1. Hardware versus Software Appliance

Feature	Hardware Appliance	Software Appliance
Form Factor	Uses fixed physical 8RU or 39RU units	Employs virtualized OVA packages
Infrastructure	Requires dedicated Cisco UCS servers	Operates on customer-managed virtual environments
Scalability	Limits capacity to the physical chassis	Enables on-demand horizontal scaling
Management	Necessitates manual physical maintenance	Automates provisioning through an Infrastructure Manager
Responsibility	Cisco maintains the entire stack	Customers manage underlying compute and storage
Storage	Relies on internal SAS or SSD drives	Utilizes shared enterprise datastores like vSAN or iSCSI
Lifecycle	Follows UCS refresh cycles	Decouples the application from hardware lifecycles
Deployment	Requires physical racking and cabling	Allows for rapid virtual machine provisioning
