I started digging into AWS, Amazon Web Services, around March of this year. At first, it was just to understand their offerings, and terminology, so I could speak intelligently to the subject with my peers.
And then, as I was fiddling around with their services, it dawned on my how powerful the tools were. I could spin up servers with a few clicks, easily monitor those instances with CloudWatch, get pricing alerts with SNS, and was blown away when I deployed my entire testing environment with Elastic Beanstalk.
And so my "fiddling around" intensified, and I wound up with 18 pages of note, dozens of hours labbing, at least a hundred hours of study, 45 minutes of test taking and on the first attempt I am an AWS Certified Solutions Architect - Associate.
