Google Cloud databases

A cloud database is a database service that is built and deployed on cloud infrastructure. Easily via the Internet. Cloud databases serve the same function as any other modern relational, non-relational, or in-memory database. But with the added flexibility that comes with cloud computing, with a cloud database, you don't have to buy dedicated hardware, and you don't have to worry about the infrastructure to run and scale the database. Depending on your needs and your team's availability, you can choose a fully-managed or self-managed service

The advantages of the database in the cloud are :

It's managed, scalable, easy to access offers disaster recovery, and is secure as the offering data is encrypted end-to-end
