How core network services enable SASE networks

In a SASE model, networking and security capabilities are intended to be tightly integrated and interoperable. And yet, to achieve its full potential for integration, a SASE-based platform must be able to harness the network services that are common to all networking and security functions — DNS, DHCP, and IP address management. Most SASE implementations, as currently offered, do not adequately integrate these services into their platforms. When incorporated as a foundational layer in SASE-based networking, core network services deliver the following advantages:

• Centralised visibility. Data residing in core network services provide enhanced network visibility for SASE implementations, enabling networking and security teams to monitor and manage devices and application usage centrally across physical, virtual, and cloud infrastructure.

• Network user context. Similarly, core network services, such as DNS, enable SASE deployments to optimise network operations and automatically secure application access at the edge.

• Local survivability for distributed locations. Resilience is a top priority for a SASE network. Applied effectively, core network services can ensure continuous Internet access for distributed locations any time they lose connectivity to headquarters.

Cloud-native delivery for core network services

The SASE framework emphasises the use of cloud-native design in networking components. As you weigh your options for incorporating core network services into the design of your edge network, seek out solutions built using cloudnative microservices and containers. Containerised instances of DDI services are faster and easier to manage than virtualised alternatives. They also consume far fewer resources and deliver extremely low latency, providing you with the dexterity and resilience you need at the network edge.
