I want to know how many end client users can single instance of Wowza support? I would have around 16 live streams out of which 3 live streams will be 720p and will have VOD of 720p. Please advise… Can you suggest how many instances would I have to have if I had to stream to 15,000 end user clients. Considering bandwidth and uninterrupted service, where would it be best to deploy all these instances. Please advise…Thanks in advance… ---

The biggest limitation will be your server hardware and network capabilities, not Wowza itself. At 1.5mbps bitrate, you should be able to support ~530 concurrent users on a 1gbps line, assuming 20% overhead. If you plan to serve content to 15,000 concurrent users ( which is unlikely if you’re just starting off ) you can pretty easily figure out that you’ll need about 30gbps at the bitrate I mentioned. For live streaming, things are easy, but for VOD you need a pretty powerful server with plenty of RAM to keep most of the content in memory, and probably SSD drives. ---

There is no limit built into Wowza, the limitations are server hardware and bandwidth. Wowza recommends a late-model dual-quad cpu, 64bit OS, 64bit Java JDK, 4-8g ram, 1-4gbs nic. You can use an origin/edge configuration to scale Wowza to meet your needs: [How to configure a live stream repeater](https://www.wowza.com/docs/how-to-configure-a-live-stream-repeater) And use the Dynamic Load Balancing AddOn to maximize efficiency of the configuration: [How to get the Dynamic Load Balancing AddOn](https://www.wowza.com/docs/how-to-get-dynamic-load-balancing-addon) And you can test your configuration with the Load Test Tool: [How to get Flash RTMP Load Test Tool](https://www.wowza.com/docs/how-to-get-flash-rtmp-load-test-tool) You can also monitor the server performance with JConsole: [How to use JConsole with Wowza Media Server](https://www.wowza.com/docs/how-to-use-jconsole-with-wowza-media-server) Salvadore ---

Thank you, Having 1 gbps if I can only stream to 530 users, how do I work on streaming to others. If I have 1gbps internet, Do I have to keep on creating new instances for every 530 users?? In such a case where will it be best to deploy these instances on. Also apart from RAM and SSD, Do I also have to look for GPU??
