When a person tries to reach another network on the internet, there is a series of checks and balance that needs to be met, and a series of protocols for each link along the chain for the user to reach their destination. In other words, much like a care attempting to reach another part of a big city he needs to drive-thru different neighborhoods that have different rules and regulations, city ordinances, and laws; if one part of the city is shut down or local authority doesn’t allow certain kinds of traffic to pass thru- say only the Presidential entourage is allowed-then then the regular Joe Some going to work will be delayed from getting there.
Sometimes the Domain Name Server that our web host uses lacks the resiliency or protocol and transparency to all the up chain and down chain infrastructure to allow a fault-tolerant passageway for heavy traffic. The traffic thru different information ones rely upon the host have the correct authorizations in its network of domains it works with. A cloud-based Domain Name Server (DNS) gives a DNS system the redundancy and fault-tolerance it needs so keep a server from being cut off from routing traffic that runs thru its infrastructure. It is known that an enterprise has often a lack of redundancy in its system thereby its infrastructure shuts down when its servers have a log jam because the information from the different zones which it handles fail to share information it needs to keep internet traffic flowing across different networks.
In the Safe Zone
A cloud base DNS keeps necessary zone information flowing thru all participation networks, so there is never a lack of synchronization between one or several networks seeking to cross from one network to another. It is similar to a person traveling from one country to another with a passport (having distributed network access) or not having a passport (failing to have a distributed network access). More enterprises are using a cloud based dns service to avoid these unnecessary failures in access across networks and to keep their traffic flowing by building in resiliency in the network.
Hello, How are you!
The worse thing that can happen when a line of communication is opened up is there is no reply to know that the communication can come thru. It is the same with a DNS server. If a person an XYZ.com sends message to ABC.com, but the DNS server cannot easily translate the message into the proper protocols expected across the two internet zones, then intercommunication cannot take place between the two networks. This is due to shared information that needs to be communicated thru the DNS server. By having the DNX server in the cloud all necessary communication is shared across all networks and not just to one DNS server; this is called a decentralized system. Thanks to the cloud this lack or resiliency and or redundancy are avoided and communication can continue to flow across and thru all networks associated with the cloud infrastructure.
