How do you cloud?

As an independent cloud architect, I find myself working in my customer's cloud of choice (could be AWS, Azure or GCP). Wondering about you.

1. Which cloud did you use most in 2020?
2. More serverless or containers?
3. Data lake, NoSQL or good old relational database?
4. Are you doing any cloud ML? how?
5. What is your favorite cloud service(s)?

Here are my answers:

1. GCP
2. Containers, sigh...
3. Data Lakes FTW
4. TensorFlow
5. Three-way TIE: GCP BigQuery, AWS S3, Azure CosmosDB
