Background jobs and queues
Combine filters →Sending mail, resizing images, generating reports and calling slow APIs all happen after the browser has been answered, which needs a process that is not the web one. Providers marketing this support a second process type and keep it supervised; providers that do not will run the application and silently drop everything queued. It is the most common thing to discover missing after choosing a host.

Who is the best host for background jobs and queues?
