When you hear talk of data going to the cloud, you probably picture a string of numbers hanging out on top of a sweet cumulus formation with a bunch of other numbers, like some kind of information heaven. In reality, the cloud isn't an amorphous bubble, but rather a computing system containing strict architecture to maximize storage space. Amazon Web Services allows you to reconfigure that system architecture, which is essential for cloud maintenance.
The Ultimate DevOps Mastery Bundle includes two courses on AWS, in which you'll learn about using Elastic Compute Cloud for redundant, low-latency applications, as well as Amazon's various database management systems like Elasticache, RDS, and DynamoDB. Essentially, by learning how AWS works, you can become a professional St. Peter, gatekeeper to your company's cloud. That's ultimate power.
Docker isn't just a person who puts your boat away for you. (That's what they're called, right? Docksmen? Boatsbros? Boaties?) It's also a program used to automatically create identical OS containers for your code, which is essential because you might have production code running across hundreds of virtual servers at the same time. Having all of those servers using a different OS container would be like playing a game of Scrabble in which everybody has letters from different languages and one player has to translate in sign language.
