I just signed up Google Cloud Platform(GCP) and got $300 free usage. It’s handy for starting a new mongo instance if you don't care about the price.
The following is the installation checklist.
- create a cloud computing resource
- follow the official guide for installation mongo db
- setup iptable rules
- set bindIp to 0.0.0.0 in
/etc/mongo.conf(should better use reverse proxy or somewhat)
- allow tcp 27017 port in firewall rules
