CDN – What is it and how does it work?CDN – What is it and how does it work?

CDN – definition

The term CDN refers to a “content delivery network.” It’s a network of servers that spans a large geographic area and has extremely particular server locations. The purpose is to cover the territory from which possible tourists may originate thoroughly. To have servers that cache data (code, photos, movies, and so on) as close to visitors as possible. Visitors will receive better and faster service as a result of this. The CDN’s other benefit is load balancing, which reduces the workload on the central server.

Round-Robin DNS – Everything you need to knowRound-Robin DNS – Everything you need to know

What is Round-Robin DNS?

Round-Robin DNS is a mechanism for administrating the incoming traffic. 

This technique is based on the time of arrival of the user request and the actual number of servers that you have. Simply you create several A or AAAA records with different IP addresses (IPv4 and IPv6) that correspond to the multiple servers. Each one of them stores a duplicate of the information for your website. So, whenever a user requests your domain name, the authoritative name server, storing the A or AAAA records, is going to provide the next in rotation turn A or AAAA records from those you created. The users are going to be automatically directed when they are desire to reach your website. The exact moment when they reach your DNS name server is important for the precise order.

DNS resolution – Essential behind-the-scenes processDNS resolution – Essential behind-the-scenes process

DNS resolution – Definition

The DNS resolution is a fundamental process that resolves a domain name to its IP address (IPv4 or IPv6). Without it, the entire Internet would work in a completely different way. However, it occurs behind the scenes because regular users don’t even notice that it is happening. People are used to typing a simple domain name, and the desired website is loaded in their browser. However, the user’s DNS query is actually traveling through several separate servers until it receives a full answer.

GeoDNS – The Best Solution For Global OrganizationsGeoDNS – The Best Solution For Global Organizations

GeoDNS – What is it?

You can find GeoDNS, also called global traffic director or only traffic director. Don’t get confused. They mean exactly the same thing! It represents a very effective technique for optimizing the incoming traffic of a domain via geographical-based routing.

If we compare the traditional DNS service and GeoDNS service, we should point out the main difference. The traditional DNS servers store an identical IP address for a particular domain. On the other hand, GeoDNS includes storing multiple IP addresses based on the location. In addition, it is an alternative for cloud-based load balancing. As a result, the overall performance of your network is going to be improved.
