Redis is insanely fast. And the APIs are great. We use transactions a ton to keep state consistent across many servers. Never had any problems with Redis -- it is rock solid!

I actually love emacs and it's a great tool to have. I use Evil Mode in emacs though, because at the core I know that Vim will be on every server I ever SSH into. JetBrains IDEs have support for Vim bindings, trivially. And it just works very well across many environments!

We use CloudFront for proxying our S3 assets to the frontend. It was a bit easier to setup versus CloudFlare for this task. Otherwise, we use CloudFlare for everything though.

Technically we do also use Cloudfront. But CloudFlare is better, hands down. More features. Better UI. Less pain points, overall. CloudFlare provides awesome tech!
