This morning, very early, I manage to take an hands on lab.
When I've finished the queue for the Self paced Labs were very long.
As always the HOL attract a lot of people, because you can experiment in a controlled environments, all you cannot do during your normal working days.
My advice is to try at least one of this labs as they are useful to understand new features, optimize your current environments improving your knowledge and get advices from the expert staff that are there to help you.
If you are CloudCred member, don't forget to scan th QR code when you finish your labs: this will give you points.
Here's the pictures of the HOL place.
