Question
Is latency optimized between EU and Asia data center or is it like everywhere else? If possible, how one can achieve reduced latency?

Title basically says it. If I measure the latency between EU (Frankfurt / Amsterdam) to, let’s say, Hong Kong, I’ll see something around ~250ms. The question is: assuming I’ll have 2 droplets created in DO, does DO have any additional resources to reduce the latency between its data centers? And if possible, how such droplets should be configured. Thanks.

Hi there,
I believe that there isn’t a direct control over the latency between two data centers on different continents. The latency between different regions is primarily affected by the physical distance and the network infrastructure between those locations. I believe that this is true for most providers as well.
In general what I personally do to optimize the latency between Droplets in a different region is to use a CDN for example, as a CDN can cache your content on edge servers distributed across the globe, bringing your content closer to your users. And also do some general optimizations for the application itself so that it is less sensitive to latency by reducing the number of round trips required between the client and server.
This will, of course, depend on the exact use case, for example for an API, you could add data compression, response caching, and batching requests.
Additionally, there are services like Syntropy that specialize in exactly this, reducing the network latency for multi-region applications.
Hope that this helps!
Best,
Bobby
