If you work in IT, every three or four years you have to update your skills. Last time it was that I had to learn MVC web development. (I liked that.) This time it is the Cloud and some other stuff. Here is a collection of the Certificates they give you these days for completing courses. I hope it looks like I've been keeping current.
Originally was studying Azure, because I exist in a Microsoft Ecology, but my company wanted Amazon Web Services, so that is where I focused my expertise. There are other classes such as Agile and Security Principles. There will be architecture classes like TOGAF and ServiceNow. I can always add what is needed.
This is the one that took a little work, but I got it, the AWS Certified Architect Associate. I have a fair amount of exploration of AWS to go.
Note that ACloud does not give a Certificate of Completion if the class is not taken through Udemy. This is what you see when the class is completed. ... This was a long tough class.
