负载平衡每个用户一个进程
我正在运行一个 Web 应用程序（在 Ubuntu 20.04 VPS 上），它是单线程的并且计算量相当大；一个 R Shiny 应用程序。因此，我需要一个负载均衡器，将每个用户/会话路由到单独的进程。我需要动态发生这种情况，这样我就只运行当时实际使用的进程，并且当新用户访问该 URL 时启动一个新进程。
目前我使用 Shiny Server Pro 进行负载平衡，但该产品可能会在一年后进入维护阶段。
我已经研究了多种可能的替代方案，从简单的 nginx 配置到更复杂的 kubernetes 解决方案，但还没有找到我真正需要的。这似乎是一个微不足道的要求，我感觉我正在寻找错误的方向。
有谁知道如何做到这一点，并且能够指出我正确的方向？
提前致谢！
I am running a web app (on an Ubuntu 20.04 VPS) that is single threaded and quite computationally expensive; an R Shiny application. Therefore, I need a load balancer that routes each single user/session to a separate process. I need this to happen dynamically, so that I only have processes running that are actually being used at the time, and a new process is started when a new user visits the URL.
At the moment I use Shiny Server Pro for this load balancing, but this product is going in maintenance moment in probably a year.
I have looked at multiple possible alternatives, from a simple nginx configuration to a more complex kubernetes solution, but have not found exactly what I need. It seems like such a trivial requirement, that I get the feeling I am looking in the wrong direction.
Does anybody know how to do this, and is able to point me in the right direction?
Thanks in advance!
