Historical provider.
Current availability of the listed service is not confirmed. Acquired by Microsoft in 2021-08-10.

Overview

Peer5 developed browser-based peer-assisted video delivery. It used viewers’ available connections alongside HTTP delivery to reduce origin and network load.

Microsoft acquired Peer5 in August 2021. Current Microsoft eCDN focuses on live video inside enterprise networks; it is distinct from public CDN caching and Azure Front Door. Existing Peer5 customers should check current support and migration options with Microsoft.

Network

Peer-assisted delivery depends on viewers, their proximity and permitted connections, rather than a fixed global cache-city list. A traditional PoP map would misrepresent this architecture.

Current Microsoft eCDN uses HTTPS, secure WebSocket signaling and UDP peer connectivity. Review browser policies, firewalls, VPN/subnet behavior and applicable service domains. Run a representative test before a large event; offload is not guaranteed by viewer count alone.

Past features

Historical Peer5 delivery

Peer5 used HTML5 and WebRTC for live and on-demand peer-assisted video delivery.

Current Microsoft eCDN

Peers work alongside HTTP delivery. The media pipeline still supplies manifests, encoded HLS/DASH segments and DRM licenses. Current event analytics and testing tools help validate delivery inside an enterprise network; check their availability for your event product and tenant.

Service status

Microsoft acquired Peer5 in 2021. The current product is Microsoft eCDN , for video events inside enterprise networks. Ask Microsoft about legacy account support, licensing and the migration path for your setup.

Recover player integrations, event URLs, tenant settings and usage records. Verify attendee eligibility, browser local-network policies and network paths, then run a representative event test. A public CDN can provide HTTP fallback alongside the peer-assisted layer.

History timeline

  • 2012 — Peer5 founded — Provider profile hosted by Y Combinator records the founding year.
  • 2021-08-10 — Microsoft acquisition announced — Microsoft announced the completed acquisition to improve enterprise video delivery; existing customers could continue at that time.

Budgeting for a replacement

Current enterprise licensing

Qualifying E3/E5 organizers can host Town Halls with eCDN included: up to 3,000 interactive attendees or 10,000 view-only attendees. Larger interactive events require an appropriate organizer Attendee Pack. Verify your tenant and agreement.

Legacy arrangements

The published USD 0.50 per benefiting user per month, billed annually, belongs to legacy per-user licensing. Older Teams Premium entitlements can offset those licenses; current Teams Premium does not automatically provide that legacy entitlement. This is not a current Peer5 traffic rate.

For replacement budgeting, count licensed participants and event capacity separately from delivered GB. The calculator can estimate an underlying public CDN or add a confirmed enterprise subscription as a monthly extra. Obtain support and migration terms for any legacy Peer5 agreement.

Historical integrations

Current Microsoft eCDN supports Teams Town Hall, Teams Live Event and Viva Engage, with third-party integrations such as MediaPlatform. Confirm the supported player and tenant configuration for the chosen event product.

  • Validate WebRTC, local-network access and current service domains.
  • Use Microsoft’s event testing and analytics before production broadcasts.
  • Confirm attendee eligibility; anonymous and cross-tenant guests do not participate in peering.

Browser local-network policies and Teams desktop requirements differ. Follow the event product’s deployment guidance and prepare the network even when no plug-in is needed.

What to know

Microsoft eCDN is worth evaluating for enterprise events with eligible participants. Test the corporate network, player behavior and fallback traffic, and confirm event licensing before rollout.

Planning a replacement

  • General public website caching or an independent global cache network.
  • Replacing media ingest, encoding, DRM or HTTP delivery with peer distribution alone.
  • Confirm event licensing and measure peer offload in a deployment test before budgeting.

History

Peer5 was founded in 2012. Microsoft announced the completed acquisition on August 10, 2021 and said existing customers could continue using the service at that time.

The current enterprise product is Microsoft eCDN . Existing Peer5 customers should check their contract and supported migration path with Microsoft.
