Design Function

Each SASE Service independently has a functional model for design provided by the developer of that service. In the process of SASE design, each functional model must be laid out to compare functions for overlap. Integration mapping will be via API and that should allow the push/pull relationships between each service. The overlay of functionality requires a policy design that eliminates competition between features, functions, or attributes utilized by each service.

SASE functional design accounts for overlap between integrated services and remediates functional overlap that could impact performance or security. Historically, this has not been a requirement for technical architects as each system or service would run independently with little to no competition at a functional level. Often, in the SDN, SD-WAN, and SASE markets, the implemented solution has a 10-30% overlap in functionality, which causes negative interactions between systems. Competition for authority...
