Just my 2 cents, but k8s 1.18+ has some great auto scaling and network load balancing... If you guys run the site on prem, OKD (origin distribution of k8s) is a great secure starting point (and you avoid paying amazon or azure for aks)

I think one of the tough parts managing the site is that the admins MuST keep the tech stack private to avoid giving any hackers a foot in the door..

But guys, plz get help... Or buy a bigger server, startup a crypto donation address, heck I think linode even let's you pay for nodes using crypto..

Just some ideas
