I often hear the argument that one should only use the standard or in the cloud, the (OpenSource) tool specific features to be able to move anywhere else anytime.

No use of AWS specifics which would make developers live easier but doesn’t exist in Azure. SQL Standard instead of effective new datatypes or procedures that are vendor specific.

My favorite quote of the article:

> „Data has gravity“. Moving data can be both time-consuming and costly.

This is a major lock-in that is often ignored.
