AWS implements latency routing policy based on the ip address of resolver or masked ip address of client. When Route 53 receives a DNS query for your domain or subdomain, it determines which AWS Regions youve created latency records for, determines which region gives the user the lowest latency, and then selects a latency record for that region.

I much respect and thank Jon Bonso. Latency routing policy - Use when you have resources in multiple AWS Regions and you want to route traffic to the region that provides the best latency. . In this paper, by studying the structural properties of Fat-tree and VL2, we propose a per-packet round-robin based routing algorithm called Digit-Reversal Bouncing (DRB). You can also optionally choose to route more traffic or less to a given resource by specifying a value, known as a bias. routing requests based on the customer's location to the nearest region. Weighted: This policy allows percentage based balancing. We show that for a two-state Markov link-dynamics model parameterized by probabilities p, q, if links are more likely to turn on than off at each time instant (p > q), a "depth-first" sampling strategy is optimal, whereas a "breadth-first" sampling strategy is optimal if links are more likely to turn off than on (p < 60; q)-under the Cut . For this configuration, you will have to select the Latency Routing Policy. Lets Route 53 serve user requests from the AWS Region that provides the lowest latency. (Optionally) provide a description. Weighted routing lets you associate multiple resources with - The single domain name (pythoholic.com) Subdomain name (apps.pythoholic.com) with power to chose how much traffic can be distributed. A bias expands or shrinks the size of the geographic region from which traffic is routed to a resource. Not the answer you're looking for?

You can configure two DNS resource records that corresponds to the websites you configured in different regions. sound really abstract, right? Despite of this, latency does not remain the same always. There are various types of routing policies such as basic routing policies, failover routing policies, geolocation routing policies, latency routing policies and so on.

The 2 static IPv4 addreses are hosted in independent network zones offloaded to ap-south-1 (that would violate our agreement). Meet other IT professionals in our Slack Community. AWS tool to compare Global Accelerator to the public internet. Fog Computing (FC) extends the computability and storage of Cloud computing paradigm to network's edge devices such as GWs. For such cases, you can create a default record which can manage queries from IP addresses that arent mapped to a location. To use latency based routing, we create a latency resource record set for EC2 (or ELB) resource in each region that hosts our website. Latency-based routing is based on latency measurements performed over a period of time, and the measurements reflect these changes. Is this meat that I was told was brisket in Barcelona the same as U.S. brisket?
