Explains how BYOS functionality enables centralized service inspection by connecting service chains to SDCI gateways deployed in the middle mile network.
Service chaining with software defined cloud interconnect bring your own service is a functionality that
-
establishes a centralized location for service inspection by connecting a service chain to the Cisco Catalyst 8000v Edge Software (Catalyst 8000v) SDCI gateways that are deployed in the middle mile network
-
enables the seamless integration of external services with the SDCI infrastructure, and
-
enforces colocated data policies, also known as centralized data policies, on these gateways within the middle mile network for selective data traffic inspection.
Network architecture
The Software Defined Cloud Interconnect (SDCI) establishes connections between branch sites and the cloud through network service providers, including Megaport and Equinix. In this context, a branch site represents the first mile, a service provider acts as the middle mile, and the cloud serves as the last mile.
The BYOS service inspection for SDCI allows service chaining in the following situations:
-
Connecting branch sites to cloud workloads through middle mile providers using the C8000v SDCI gateway.
-
Interconnecting branch site through the middle mile provider using the Catalyst 8000v SDCI gateway.
-
Facilitating intercloud traffic connectivity by the middle mile provider through the Catalyst 8000v SDCI gateway.
