Domain Name System – DNS
DNS – Domain Name System is an amazing technology. It helps us open internet addresses without a hustle. We easily write the domain name and the DNS has the job to find the IP of the domain we wrote. Just like the phone book on your mobile phone, you need to find Mike, so you write “Mike”, and you don’t need to remember his actual number, great isn’t it?
DNS is an essential part of the Internet. It manages to translate all the inquiries into IP addresses, and like this, it can identify different devices that are connected to the network.

The network performance has become incredibly important. No matter if your organization is big or small, you don’t want to experience operational issues or network reliability problems. Load Balancing managed the demand by distributing the traffic and the application load over different servers depending on their current load.
It is not a new invention. In its early days, it was used between the end device and the application servers to check the servers and to send traffic to the least occupied.
But with the evolving of the networks, the load balancing has gotten a new shaped. Now it is not a simple distribution system. The load balancing has become very divided.
For example, there is application load balancer which distributes one single application over the servers; there is another which distributes only between the server cluster; another directs the traffic from multiple paths to a single destination.
Other load balancing solutions are very advanced. They can shape the traffic and act as intelligent traffic switches, do different health checks on the content, applications, and servers, add extra security on the network and protect it from malicious software and improve availability.

We already showed you what DNS is but do you know what CDN stands for?
A CDN – Content Delivery Network is responsible for the content delivery. We all interact with CDNs on a daily basis – when we watch a video, when we read an article, when we shop online or when we use a social network site. The main reason why they exist is to reduce latency, the delay between your demand and the moment it gets on your screen. Higher latency makes us impatient and gets us angry. There are many reasons it can happen, but the main is the physical distance between your computer and the server which hosts the website. CDN makes the magic of shortening that distance, and by doing so, it improves the speed dramatically.

DNS and why does it matter?
DNS – domain name system is a marvelous invention. It makes it easy for all of us to enter our favorite addresses on the web. We don’t need to remember thousands of IP numbers of all websites that we use; we simply write the domain name and the DNS magically matches our text with the associated IP and show us the result.

Anycast DNS is one amazing technology that can save you a lot of time.
But first, let’s explain it to you in a simple way so you really understand why this can help you with your company network.
What is a DNS server?
Imagine it as a massive phone book. They contain a register of domain names and translate them to IP (internet protocol) addresses. For us humans it is easy to remember the domain names but the computers, they prefer numbers to orientate so they access websites based on their IPs.
The information of those DNS servers is saved and organized in the Central Registry. Internet providers and Host companies need to check with the Central Registry to get all the DNS updates.
When you write the following web address www.facebook.com, your service provider will check the DNS for this website, then translate to machine language and direct you to the following IP 184.108.40.206.
