SD-WAN Architecture Guide: Hybrid WAN For Distributed Enterprises

Reference architectures, vendor decision criteria and operational playbooks for SD-WAN at scale.

→INSIDE THE REPORT

Five chapters. One operating reality.

01 · When SD-WAN is the right answer

Branch-heavy operations, cloud-first traffic profiles, distributed retail, multi-region enterprise. The use cases where SD-WAN is the wrong answer are smaller than the marketing suggests — and larger than the SD-WAN community admits.

02 · Reference architectures

Three patterns: full-mesh (most enterprises), hub-and-spoke (security-heavy estates), regional-mesh (multi-continent operations). Each pattern with its own underlay strategy.

03 · Vendor evaluation

Cisco, Fortinet, VMware, Palo Alto, HPE Aruba, Versa. Where each platform genuinely leads, and the operational shape of running it at scale.

04 · Underlay strategy

MPLS, ILL, broadband, LTE/5G. The mix that works for most enterprises is hybrid; the mix that works for any specific enterprise is whatever survives application-aware routing in production.

05 · Operations and SLAs

What to monitor, what to alert on, how to structure a vendor SLA with teeth, and how to measure SD-WAN value beyond cost.
