I am evaluating the use of WOWZA for streaming video over HLS so I apologize if the question sounds a bit "non polite", but here it is:

HTTP servers like Apache HTTP server, Nginx and others can stream HLS as well as WOWZA. What advantages WOWZA has over these HTTP servers when it comes to streaming HLS?

(any consideration is relevant, including scalability, security, monitoring and reporting, ease of management etc.)

Thanks in advance,
