Cloud networks do not support native multicast.
In today's hybrid world, moving multicast-based workloads between on-prem environments and the cloud shouldn't feel like a compromise. Yet traditional cloud networks have a glaring limitation: they simply don't support native multicast or broadcast the way on-prem hardware does.
Enter swXtch.io.
Their software-defined solutions - cloudSwXtch for the cloud and groundSwXtch for on-prem - create a unified, high-performance overlay network that finally bridges the gap.
With cloudSwXtch deployed as a lightweight virtual switch in your VPC (on AWS, Azure, Google Cloud, Oracle Cloud, or anywhere else), you get true standards-based multicast, SMPTE ST 2022-7 hitless redundancy, lossless UDP for reliable high-bandwidth flows, protocol fanout/conversion, and precise timing (PTP). Pair it with groundSwXtch, and you unlock bidirectional traffic:
Multicast originating on-prem tunnels seamlessly into the cloud over standard ground-to-cloud links, with packet protection to maintain integrity and low latency.
Cloud-generated multicast flows pull down to on-prem environments just as easily.
Achieve hybrid workflows like cloud bursting for live events, remote production, satellite replacement, or disaster recovery - without ripping and replacing infrastructure, rewriting applications, or settling for inefficient unicast workarounds.
The result?
Enterprise-grade performance that feels like bare metal, enhanced observability through swXtch.io’s wXckedEye monitoring tool, reduced complexity and costs, and freedom from vendor lock-in. Industries from media & entertainment to government/defense, financial services, and infrastructure are already leveraging this to modernize without disruption.
If you're tired of multicast roadblocks holding back your hybrid strategy - or if you're exploring ways to bring ST 2110, JPEG-XS, SRT, or real-time audio into the cloud reliably - swXtch.io delivers the networking layer the major clouds never built natively.
