I wrote a blog post about a simple multi-cloud stack. There are a bunch of vendors who are doing the work in their layer of the stack, so you can use a multi-cloud web host, and a multi-cloud database, and you'll be most of the way there. I wrote a blog post about how easy it is to get multi-cloud robustness for single page apps here: https://blog.fauna.com/survive-cloud-vendor-crashes-with-netlify-and-faunadb https://blog.fauna.com/survive-cloud-vendor-crashes-with-net... Of course it becomes more complex as the app becomes more complex. But more and more of the AWS/GCP/Azure services have multi-cloud equivalents, so this architecture only gets easier to implement.
