My EC2 instance is located in AWS-East-1 (US). It makes rest calls to a server (crypto exchange) hosted in AWS Tokyo. Currently, over the internet, it takes 175ms for data packet round trip.
How can I achieve lowest latency in this connection? I have read about AWS Global Accelerator, Direct Link/Connect etc. but I am not sure what's the right solution here.
Kindly explain the best architecture for network packet routing and whether I can use an existing AWS service for this.
