Thanks to the great courses by “A Cloud Guru” I am now certified as AWS Certified Solutions Architect (Associate):

AWS Certified - Miguel Rincon

This certification requires to review a lot of material, multiple AWS products, as well as live practice in the AWS environment. I built my AWS expertise, so now I can get around setting up a virtual network and running my own infrastructure on AWS.

The certification lasts 2 years, after which I will have to be re-certified, as AWS offering is changing very fast.
