Ask HN: How would you host this?

I need to host an application and I'm looking for the cheapest option that considers the following... * The front-end is written with React * The back-end is written in Node + Express * The database is MongoDB * We don't need much storage. 512 MB should be fine for a while * We need daily database backups * The site will have around 30 users and will be less than 1 concurrent request per second * We will require SSL (HTTPS) * We can't use the free limits for our AWS account * I'm the only one who supports this app and I want something reliable and easy to set up and maintain How would you host this app?
