Overview
Microsoft eCDN helps offices avoid downloading the same live-event video separately for every employee. It combines browser-based peer sharing with HTTP delivery.
Microsoft acquired Peer5 in 2021. The current service addresses enterprise events rather than public website caching.

Pricing
Qualifying Teams Enterprise licenses include eCDN for Town Halls within their attendee limits: up to 3,000 interactive or 10,000 view-only attendees. Larger interactive events use organizer attendee packs.
Legacy Teams Premium and standalone arrangements have separate terms. Confirm your tenant’s entitlement and event size rather than applying an older universal per-user rate. Monthly traffic in GB is not the licensing unit.
Developer tools
When it fits
- Company-wide video events with many viewers in the same offices.
- Teams administrators planning Town Hall capacity and office-network load.
Before you choose
- It does not replace a public website CDN.
- Licensing, viewer eligibility and browser policies affect deployment.
