I have used AWS and Azure before. 

We used Alibaba Cloud for SQL two years ago. We moved from Alibaba Cloud to Google Cloud SQL for better technology support. Hosting OpenShift was difficult on Alibaba, so we switched to Google Cloud.

We previously used Postgres. Managing the DBs was a little tedious, so we migrated them to Cloud SQL.

I have experience with Oracle Database.

We also use PostgreSQL in GCP and BigQuery too for extract information from Jira.

I have previously worked with Microsoft and Amazon AWS. I switched because I just like Google. I think it's a great platform. 

The two main competitors are Microsoft and Amazon Web Services. Out of these three, Google is the smallest when it comes to cloud in general, but I am pretty happy with how things are moving. I've been using Google for many years now and the services and it runs very well. I also use G Suite, Google Docs, you name it. It all works really well. It's user-friendly, to the point, it's not complicated. Whereas with Microsoft and some Amazon services can get quite complicated.

Although, maybe some of their services are more expanded, and maybe you can do some more. From a technical point, they are more advanced sometimes. You could say that for Amazon. My experience is that if a tool is easy to use and you get the job done in the fastest way possible, that tool has a great chance of becoming the leader because it's about user-friendliness. With Google, you get the job done and that's why you use these companies. 

I previously used a different solution for our marketing database, but it was very limited in scope. Moving forward, Google Cloud SQL is the only data warehouse I will ever use.

When we were using the Rackspace, we only used Rackspace virtual machines, for our virtual machine requirements, as well as our own SQL requirements. So, we had virtual machines, hosting SQL databases. And, it didn't really work out in our favor.

Hosted MySQL DB, maintained by DBA; reason for switch: overall move to the cloud of other GCP components.
