Streaming endpoints overview


In Microsoft Azure Media Services (AMS), a Streaming Endpoint represents a streaming service that can deliver content directly to a client player application, or to a Content Delivery Network (CDN) for further distribution. Media Services also provides seamless Azure CDN integration. The outbound stream from a StreamingEndpoint service can be a live stream, a video on demand, or progressive download of your asset in your Media Services account. Each Azure Media Services account includes a default StreamingEndpoint. Additional StreamingEndpoints can be created under the account. There are two versions of StreamingEndpoints, 1.0 and 2.0. Starting with January 10th 2017, any newly created AMS accounts will include version 2.0 default StreamingEndpoint. Additional streaming endpoints that you add to this account will also be version 2.0. This change will not impact the existing accounts; existing StreamingEndpoints will be version 1.0 and can be upgraded to version 2.0. With this change there will be behavior, billing and feature changes (for more information, see the Streaming types and versions section documented below).

Azure Media Services added the following properties to the Streaming Endpoint entity: CdnProvider, CdnProfile, FreeTrialEndTime, StreamingEndpointVersion. For detailed overview of these properties, see this.

When you create an Azure Media Services account a default standard streaming endpoint is created for you in the Stopped state. You cannot delete the default streaming endpoint. Depending on the Azure CDN availability in the targeted region, by default newly created default streaming endpoint also includes "StandardVerizon" CDN provider integration.


Azure CDN integration can be disabled before starting the streaming endpoint. The hostname and the streaming URL remains the same whether or not you enable CDN.

This topic gives an overview of the main functionalities that are provided by streaming endpoints.

Naming conventions

For the default endpoint: {AccountName}

For any additional endpoints: {EndpointName}-{AccountName}

Streaming types and versions

Standard/Premium types (version 2.0)

Starting with the January 2017 release of Media Services, you have two streaming types: Standard and Premium. These types are part of the Streaming endpoint version "2.0".

Type Description
Standard This is the default option that would work for the majority of the scenarios.
With this option, you get fixed/limited SLA, first 15 days after you start the streaming endpoint is free.
If you create more than one streaming endpoints, only the first one is free for the first 15 days, the others are billed as soon as you start them.
Note that free trial only applies to newly created media services accounts and default streaming endpoint. Existing streaming endpoints and additionally created streaming endpoints doesn't includes free trial period even they are upgraded to version 2.0 or they are created as version 2.0.
Premium This option is suitable for professional scenarios that require higher scale or control.
Variable SLA that is based on premium streaming unit (SU) capacity purchased, dedicated streaming endpoints live in isolated environment and do not compete for resources.

For more detailed information, see the Compare Streaming types following section.

Classic type (version 1.0)

For users who created AMS accounts prior to the January 10 2017 release, you have a Classic type of a streaming endpoint. This type is part of the streaming endpoint version "1.0".

If your version "1.0" streaming endpoint has >=1 premium streaming units (SU), it will be premium streaming endpoint and will provide all AMS features (just like the Standard/Premium type) without any additional configuration steps.


Classic streaming endpoints (version "1.0" and 0 SU), provides limited features and doesn't include a SLA. It is recommended to migrate to Standard type to get a better experience and to use features like dynamic packaging or encryption and other features that come with the Standard type. To migrate to the Standard type, go to the Azure portal and select Opt-in to Standard. For more information about migration, see the migration section.

Beware that this operation cannot be rolled back and has a pricing impact.
