I don't want to be that guy making the pointlessly critical comment, but what is the use case for an in-memory database on the other side of an ethernet link? Even if you're in the same datacenter it's going to be slow, no?

I get that startups need to move fast in order to validate ideas, but redis is hardly a chore to set up.

Either way, congrats on the redundancy.

Hi Jonnie,

This is a very valid comment, we always recommend having your Redis server as close as possible to your application server. We're following the lead from Heroku, which offered this Alpha feature for Postgress in US-WEST https://status.heroku.com/incidents/460 .

We've been offering custom HA (master, slave setups) for a while. This is the first step towards giving our customers more choice for their availability zones.

Redis 2.6 Sentinel is exciting development and something that we're experimenting with now it's in the latest Redis release.

Feel free to send me any questions to ben@redistogo.com

One argument I can see is if you're already on e.g. a small VPS and going up to the next tier is more expensive than moving your redis instance off somewhere else. Or, not specific to this but to the idea in general: moving a resque queue and workers into EC2 to handle widely-varying traffic and faster scaling than ordering more machines at a datacenter. Then redis is just a nice atomic list manager that everything already integrates with.

A disk seek (e.g., if you have more data than RAM and are using virtual memory) might take ~10ms. A packet round trip within the same AZ in EC2 is <0.5ms.

How is security handled for this service?

I have the same question; since http://redis.io/topics/security mentions "it is not a good idea to expose the Redis instance directly to the internet", even with a strong password, are there specific measures to counter-balance this in the RedisToGo setup?

Edit: I've contacted RedisToGo to ask them directly.

We've put in place the best practices advised by Salvatore. http://redis.io/topics/security. `In general, Redis is not optimized for maximum security but for maximum performance and simplicity.`

There are few projects building SSL into Redis https://github.com/tritondigital/ssl-redis; but nothing has been fully adopted by the community yet.

We offer a VPN, SSH and IP restrictions to bolster security. We currently only offer these to our larger plans, but can offer a custom solution depending on your requirements.

Hello Ben - thanks for your reply!

isn't this a bit pricy ? why not just drop a medium VPS/server and put redis on it ?

Because then you're administering your stack components again.

But the premium for having it administered (and backed up, and having support, and the extra stack tools) is a bit too pricy, isn't it?

Too bad our beautiful West Coast is also prone to earthquakes :(

and AWS Dublin... is prone to lighting and rainbow attacks. http://www.datacenterknowledge.com/archives/2011/08/07/light...
