As enterprises accelerate cloud adoption, one challenge consistently rises to the top: how to connect on-premises infrastructure to cloud platforms with the same performance, predictability, and security historically expected from private data center networks. Internet-based connectivity—whether via traditional VPNs or public routing—introduces latency variability, bandwidth constraints, and operational risk that quickly become unacceptable for mission-critical workloads.

Oracle Cloud Infrastructure FastConnect was designed to solve this problem. FastConnect provides enterprises with a dedicated, private network path into OCI, bypassing the public internet entirely and delivering deterministic performance, higher bandwidth, and enhanced security. By leveraging industry-standard routing with BGP, flexible connectivity models, and scalable port capacities, FastConnect enables hybrid and multi-cloud architectures that behave more like an extension of the enterprise WAN than a remote cloud endpoint.

Drawing on decades of global network engineering experience and hundreds of real-world OCI deployments, this guide examines FastConnect from an architectural and operational perspective—covering design patterns, routing considerations, redundancy strategies, security tradeoffs, and enterprise use cases. Its goal is simple: help organizations design FastConnect implementations that are not only functional, but resilient, scalable, and future-ready.
