We are planning to use discourse as a webview in a part of our mobile application with more than 1 million users. We will direct users to the forum with notifications. This means 3-4K users instantly rushing to the forum. Considering the resources that Discourse consumes, what features should a server have to handle such traffic? We are using Digitalocean. Before buying a separate server for the forum, I want to get the opinion of you valuable forum users.
