Quick thoughts:

• Easy to get "stuck" deployments or config changes, that leave the app/stack in an non-abortable, non-recoverable state for long periods of time. Like, an hour

• Deployments are very slow.

• The case when config changes (e.g. bumping the stack "version") needs you to build a new stack, failover DNS to that, is slow and pretty terrible

• The way it uses Cloudformation is weird in that it creates a second, oddly named Cfn stack. It's just.. weird, and confusing for new players

• .ebextensions must be idempotent - easy trap for beginners (who are the target audience)

  • If you're not careful, you can leave your system in an indeterminate state

• Failures in those scripts can break your deployment

Cool advice for new Web Dev People

Bootcamps / General Assembly

There are code bootcamps, like https://generalassemb.ly/

They'll teach you the basics about Javascript/node.js, some Ruby on Rails, some SQL, some MongoDB (yuck!), HTML, CSS/SASS, APIs, AJAX and stuff like that.

It's real pricey, (AUD$12k), and is 3 months full-time
