title: Node.js distributed shared memory solution
body: <p>I have a couple of load balanced node.js servers that need to have some shared state. All servers have high frequency in both reads and writes. What would be a good approach for a consistent shared memory among all instances that wouldn't be a bottleneck as much as possible? I initially went with redis, which is still an option unless there are better approaches for dealing with this. Also, Would a central server approach be a good alternative?</p>
