Hmm, it may be tricky to redo the infrastructure to remove Redis. I use a triple storage system of Local Cache => Redis => MySQL, where each is a fallback for it's previous. I also use Redis for other things that can be done quicker than sql, like a real-time leaderboard.

RabbitMQ is also integrated heavily between the different services.

Looking at Heroku, it seems a bit overpriced for MySQL and Redis, the cheaper offerings don't offer much RAM.

I might look at VPS/Bare metal to host all the infrastructure. Thanks!
