This is a great deck, but I'd love to see one on how we can use Redis at Heroku; it looks like the options are (a) Redis To Go, which is unreasonably expensive, and (b) an insecure connection to an m.large at EC2.

Insecure? Why not use ssh port forwarding?

tptacek5• 15 years ago

I'm not in love with the idea of using SSH for this, but, can you do that on Heroku?

Communications are secure among EC2 instances within us-east, which is where Heroku is.

I think the issue is that of you open up your EC2 instance's security group to your Heroku app, you're opening it up to any Heroku app.

Secure meaning there is a private back-end network or there is some form of tunneling/encryption end-points available and enabled by default for instances?

Here's the current AWS security guide that I was able to find:

I'm unwilling to trust IP access control for anything in 2011.

If I could do SSH port forwarding, that'd probably be my first choice. I have a AES-128-CTR+HMAC-SHA256 encrypted sleeve for the Redis protocol with an attendant Redis::Connection driver, but this is exactly the kind of thing I'm always telling people not to do.

A little bit off topic, how did this individual create the presentation in HTML5?
