Dynamic DNS Solution on Azure
is technology where the DNS of a website or resource is changed to point to a resource at another location without disruption of service. This redirection is transparent to the user and happens almost instantaneously. Conceptually this process is similar to Load Balancing, the difference being that the resources are hosted at different locations. This is most effective when used in cloud environment where resources are located in different regions.
Latency Based DNS Redirection
Imagine a scenario where a popular website is receiving request from different parts of the world. In normal circumstances the site would be overwhelmed with request and stop responding altogether. The popular solution will be to have more servers so that the requests can be distributed between the servers through load balancing. This strategy is is usually limited a small office with local clientele and is fraught with risk. If the network suffers an outage or if the load balancer itself fails, the site will not be available any more. This will lead to loss of business and reputation. For a business with worldwide client presence, this will lead to huge delay in response. the users nearest to the location or with minimum hops will be served first while the others have to wait. Part of the solution to the problem is to have servers at various regions. The other part is to implement a Dynamic DNS solution from Cognosys.
This solution provides latency based redirection of traffic. That is, it determines which is the nearest location for replying the request and redirects the traffic there. All this happens within 1 second and the user is totally transparent to the happenings
