#6 Handle High concurrency
1. Shard: A machine can not resist is divided into more than one machine, several people cloud is a PAAs platform, PAAs platform is easy to do the expansion, the original 300 instances now do 3,000 units, click on the page button, 10 seconds can let 3000 instances up, do 3,000 shards.


2. Queue: Sometimes there are some peaks, we do not want to be defeated by the peak, so we use the queue buffer, the system has a number of places to use the queue, such as transfer in memory to build multiple queues, alarm events using Redis to do the queue service.


3. Index: Indexes can speed up queries.


4. Current limit: The back end of the interface can not withstand pressure when the current limit.
