Thanks for the suggestion! Actually I have already started to look into using Backend instance to build a memcache service. Do you know the service behavior of backend instance on multiple parallel requests? Will these requests be queued and served one by one, or will multiple requests be process in parallel? I could not find any document on its behavior. When traffic grows, since backend memcache instance can become a bottleneck to the system, it's important for me to understand capacity of each instance and plan ahead.
And I really like your idea of cloud-sql! It seems support parallel requests by default. If data is mostly stored in memory, its performance should be good. I will also look into it. If anyone on the forum has some performance data on cloud-sql instance, please share with me. Thanks!
