If you want to support PeerTube, you can <a target="_blank" rel="noreferrer noopener" href="https://soutenir.framasoft.org/en">support Framasoft with a donation</a>, but also by helping others to discover and <a target="_blank" rel="noreferrer noopener" href="https://joinpeertube.org/">learn more about PeerTube</a> and our projects: sharing is caring!
Except for video transcoding, a PeerTube instance is not CPU bound. Neither Nginx, PeerTube itself, PostgreSQL nor Redis require a lot of computing power. If it were only for those, one could easily get by with just one thread/vCPU.
You will hugely benefit from at least a second thread though, because of transcoding. Transcoding is very cpu intensive. It serves two purposes on a PeerTube instance: it ensures all videos can be played optimally in the web interface, and it generates different resolutions for the same video. PeerTube support for offloading transcoding to other machines is <a target="_blank" rel="noopener noreferrer" href="https://github.com/Chocobozzz/PeerTube/issues/947">being discussed</a>, but not yet implemented.
1/2 GB of RAM should be plenty for a basic PeerTube instance, which usually takes at most 150 MB in RAM. The only reason you might want more would be if you colocate your Redis or PostgreSQL services on a non-SSD system.
In early August we finalized the work on the moderation tools: accounts and comments reporting, improving the administration and moderation interface, reporting logs, messages between the moderation team and the reporter…
There are two important angles to storage: disk space usage and sustained read speed. To make a rough estimate of your disk space usage requirements, you want to know the answer to three questions:
In early june, we released PeerTube 2.2 and less than two months later we are releasing this 2.3 version. We are proud to move forward so fast on PeerTube development! As we continue to follow <a target="_blank" href="https://joinpeertube.org/en_US/roadmap">our roadmap</a>, this release incorporates the features we told you about in the latest news. Let's look around and see what it brings us...
Do you want to enable transcoding? If so, do you want to provide multiple resolutions per video? Try this out with a few videos and you will get an idea of how much extra space is required per video and estimate a multiplication factor for future space allocation.
