7:44 The file name specified in the terminal is not the filename you're pointing your mouse at in the directory. And then you file you uploaded was the ORIGINAL file, and not the SHADED one that replaced it. It's stuff like this that confuses me. Aren't those two different files? If the file names are intentionally different, that seems like something to mention.
Why is the filename in the terminal different from the ones in the directory?
If the point was to replace the ORIGINAL jar with the SHADED jar, why did you then upload the ORIGINAL jar instead?

how to install maven shade plugin for intelliJ?

[AleksandarT]

Great video! I guess maven shade plugin is meant to be used to create uber jar for non Spring Boot apps, because Spring Boot uses spring-boot-maven-plugin, is that correct?
Also just as a food for thought, why is maven shade not used by default for Spring? Any advantages of the spring-boot-maven plugin? Or it is built on top of maven shade plugin?

In the 1st example, i don't understand when you 'test' using empty string, and 'test' succeed. what test is it? is the lambda running the junit test you write earlier, because it's also packed in the jar? or it's just calling the handler deployed in aws and see that SOME response is coming back (but not verifying the value of response)?

[coderlicious]

Superb. Thank you
Do you know if there is a way to configure your AWS lambda account, to tell Amazon a max dollar amount you want to spend, and then if you accidentally exceed that amount with your resources, they either immediately notify you, or just simply shut down your site? I'd prefer it works that way.

I'd hate to get a big surprise bill from amazon, because I didn't know my code was very inefficient, and the code was spending too much time during a function invocation.

I can't understand why your jar is sno small (2.5KB). My Jar is 16.
