What are some recommended VPS hosting options for a websockets server?
My websockets server is currently hosted on a VPS, but I'm unable to fully utilize the resources available due to the hoster's restrictions on the maximum number of simultaneous connections. This is not related to RAM or CPU usage.

I've already tried using a VDS, but encountered issues with DDoS attacks and threat of disconnection due to high traffic. I'm unsure what measures I can take besides moving my server to another host. 300-400 online users is typical for my usage, and my memory consumption stays below 1512mb with minimal CPU usage.

Ideally, I would like to find a budget-friendly hosting provider that doesn't impose such strict connection limits, although this information is often not clearly stated in common tariff plans.

It's probable that you've encountered the Linux kernel configuration that sets a limit on the maximum amount of connections. If you happen to have a KVM-based VPS, then you can take care of it by yourself.

 
You may contact tech support, inform them that it's a common issue, and request them to modify their anti-DDoS settings. Alternatively, you could refrain from contacting them at all and abandon their anti-DDoS feature.

 
In general, people who are overly concerned about such things can be quite strange. Personally, I have implemented a dozen reverse proxies with the same unusual traffic pattern as compared to the conventional web server, and everything runs smoothly.

 
Furthermore, there are several hosting providers that are well-equipped to handle these kinds of issues, such as vscale.io, adman.com, and OVH.
