Ask HN: What are some of the best ways to self-host software?

I make and sell a few self-hosted web applications and I'm looking for additional options to provide my customers for self hosting. The application requires a LAMP stack, and generally installation is pretty simple, but some users still struggle. Those of you that self-host, what methods are you using to deploy your apps? Do you have any tips that I can use to ease installation for my users?

Here are links to the apps that I built and sell:
