The first concrete principle is open networking (or disaggregated) switch hardware. Mainstream IT organizations are driving initiatives to on-board cloud-style networking, and gain the associated benefits.
Core & Pod Design
The 2nd concrete principle of cloud-first networking is deployment topology that leverages core and pod design principles.
Software controls are critical to make the underlying hardware networking infrastructure logically centralized. According to the Google design principle: Logically centralize with a hierarchical control plane.
Data center operators have been overwhelmed with network complexity during the last twenty years, and hence our 4th principle focuses on network automation.
Network security (who can talk to whom) is a fundamental construct of any data center network deployment. Hence, we have selected controller-based access control list (ACL) as the 5th principle of cloud-first networking.
Network analysis, telemetry, and visualization are critical in any data center network transformation project for rapidly identifying application performance/connectivity issues, for capacity planning, and for predictive network behaviors.
For principle 7 of cloud-first networking, we picked a popular public cloud construct whose impact can be monumental when broadly deployed in mainstream data centers: virtual public cloud (VPC) on-prem.
