Learning 'the cloud'
What is the fastest, easiest tutorial for learning cloud technologies? I realize that is a vague question but that is only because I know so little I do not know how to ask a defined question about this. For example, there is cloudacademy that focusses on AWS certification. If we use that as the benchmark - learn and achieving AWS certification - then what tutorials are recommended? I realize there are other clouds out there - Microsoft Azure, Google cloud, and others. Would AWS certification include all the knowledge needed to 'operate' in those clouds? Or is it like the old Microsoft, Sun, IBM propietary systems where the languages were so different and interoperability was not even defined?
