How fast can servers talk to each other within a data center? Here I'm visualizing both the inter and intra availability zone latencies within Amazon's us-east-2 data center. Communicating between servers within an AZ is much faster! Check it out at

The data came from here: Includes latencies for many other AWS data centers too.

Really neat idea! I remember at Google there was an internal tool called “bloodbath.” It was a grid showing latency/packet loss between DCs. So you’d have all DCs both horizontally and vertically, and where each pair met you’d display the latency.

I keep hoping someone will visualize latencies with load.

Can you elaborate a little?

What’s the best estimate of the physical distance of the AZs based on this? Intriguing 😁 Great stuff!

That's a great question. I know very little about the physical layout of AWS regions. But i know some people at PlanetScale might...

220us within data center is kinda slow. I think you can get 50us with DPDK in public clouds and 5us on-prem. Microsoft did some benchmarking of this:

Do it! Let me know what you find. Would be cool to compare intra-AZ, inter-AZ, and inter-region
