You can definitely install Redis on a DigitalOcean droplet. It's usually suggested that you have a separate instance for each Rails app, but you can uses the same Redis for multiple apps if you wanted to. You might want to look into using something like redis-store as it will allow you to set up separate namespaces for the keys in Redis, or you could just prefix your key manually.
