Business Bonus: AWS Outage (12/7/2021)

  There was an AWS outage a few days ago; You were probably impacted in one way or another. If any of my appliances would ever e-mail me, I think I'd die of shock. Every thing from Disney+ to McDonalds was affected, as US-East-1 was US-East-None for a few hours. Even Amazon delivery drivers and warehouse workers couldn't complete their breakneck, no bathroom, tasks. My Alexa couldn't reach AWS. "Guess I better attach it to the new hotspot..."

Case Study: The Offline/Online Laptop

Two Factor Authentication and AWS Cognito Identity Pools

There's always a video to watch. Things to learn, labs to try - and a thought hit - What service does AWS provide that allows users to log in with Two Factor Authentication (2FA)? A refresher; 2FA is a combination of what you know, who you are, what you have - and in the future, probably what you ate for breakfast - to log into sensitive systems.  As of 2021, Google made 2FA mandatory for logging in to your Google accounts For the DoD folks out there, that keycard you use to log into a computer is a form of 2FA.  A fingerprint scanner, or an authentication app on your phone also count. Back to the question - Does AWS have options for 2FA if you use their Directory options?
