- Root credentials can now be changed easily. Before, a two-step process was required to
   change the cluster root credentials since they were used to en/decrypt the IAM data.
   So, both - the old and new credentials - had to be present at the same time during a rotation
   and the old credentials had to be removed once the rotation completed. This process is now gone.

## Server Machine and Server Program { #server-machine-and-server-program }

There's a small detail about names to keep in mind. 💡

The word "**server**" is commonly used to refer to both the remote/cloud computer (the physical or virtual machine) and also the program that is running on that machine (e.g. Uvicorn).

Just keep in mind that when you read "server" in general, it could refer to one of those two things.

  `I'm afraid I don't know one,' said Alice, rather alarmed at
the proposal.

  `Then the Dormouse shall!' they both cried.  `Wake up,
Dormouse!'  And they pinched it on both sides at once.

  The Dormouse slowly opened his eyes.  `I wasn't asleep,' he
said in a hoarse, feeble voice:  `I heard every word you fellows
were saying.'
