If you send a live stream to YouTube, you generally do not need to provide a separate CDN. You send your stream to YouTube through its ingest workflow; YouTube handles delivery to viewers. A CDN is more relevant when you run your own video website, app, or streaming service and need to deliver video from infrastructure you control.
The distinction is between getting a stream into YouTube and delivering video from your own service to viewers. Those are different jobs.
What a video CDN does
A content delivery network (CDN) uses distributed servers, often called edge locations, to deliver eligible content closer to viewers. When a request can be served from a cache, the CDN returns the stored response; when it cannot, the CDN retrieves the content from an upstream origin. Whether a response can be cached depends on factors such as cache policy and cache keys. Google explains that its Cloud CDN caches content reactively as requests pass through and responses qualify for caching: Cloud CDN caching behavior.
For video services, a CDN can help serve high-throughput media and reduce repeated requests to an origin. Google describes Media CDN as optimized for streaming video and large downloads, and documents layered caches and origin shielding as ways to reduce repeated origin fills: Media CDN overview. The actual effect depends on the service’s audience, content, cacheability, and configuration; a CDN does not guarantee a particular speed improvement.

A CDN is not a camera, encoder, or live-stream ingest endpoint. It does not create or encode your video, and it cannot guarantee that a viewer’s connection will sustain a chosen resolution.
How YouTube streaming fits in
When you stream a live program to YouTube, your encoder or streaming setup sends media to YouTube. YouTube’s Live Streaming API documentation describes supported workflows and protocols; its DASH guide, for example, describes media segments delivered to YouTube over HTTP: YouTube DASH ingestion protocol. This is the creator-to-platform ingest path.

Once the stream is on YouTube, Google handles delivery to viewers. Google says that the majority of Google Global Cache traffic is cacheable YouTube content; high-volume requests may be served from a local Google Global Cache node or from Google core locations. Google chooses the serving location according to operational factors: Google Global Cache and Interconnect.
That does not mean every YouTube request is served from a local cache, nor can a creator control which location serves a particular viewer. Google’s public documentation describes aspects of this delivery system, not the complete route for every request. The practical conclusion is that an ordinary creator sending a stream to YouTube does not need to bring a separate CDN for YouTube’s viewer delivery.

What you need to stream to YouTube instead
Your production needs depend on how you make the stream. A live camera production may call for a camera, microphone, computer, or hardware encoder; another workflow may use different equipment. These are production choices, not CDN requirements. YouTube’s documentation describes the ingest workflow, but does not make any one physical device a universal requirement: YouTube Live Streaming API ingest documentation.
For a creator’s usual live workflow, focus on a suitable encoder or streaming setup, a stable upstream connection, and YouTube’s ingest instructions. A CDN does not replace those pieces.

When a separate CDN may make sense
Consider a CDN if you operate a separate video website, app, course platform, or streaming service and serve media from an origin you control. Google describes Media CDN as able to fetch content from origins in Google Cloud, another cloud, or on-premises infrastructure: Media CDN overview.
Before choosing a provider or architecture, assess the actual workload rather than assuming a CDN is automatically faster or cheaper:

Google positions Cloud CDN for a mix of static and dynamic web assets, and Media CDN for high-throughput egress such as streaming video and large downloads. That is Google’s product positioning, not an independent comparison of providers: Cloud CDN overview and Media CDN overview.
Keeping a YouTube channel live with prerecorded video
If by “YouTube streaming” you mean keeping prerecorded videos playing as a continuous YouTube live stream, a CDN still is not the viewer-delivery tool you need. You need a way to send the video to YouTube and keep that stream running. You can operate that workflow yourself, or use a cloud service that loops uploaded videos to YouTube.
Or let it run in the cloud
StreamNeo is a YouTube-only cloud service for keeping a channel live from uploaded videos or a playlist: upload your video, add your YouTube stream key, and go live. Your computer and home connection do not have to stay on.
