What is CDN (content delivery network)
CDN is a network of servers geographically located in different areas around the world. They serve as a load balancer that redirect the traffic that goes to your website to the closest Point of Presence near you. It is like a shortcut. Now your visitors will not waste time to get to the web host service you use. They will be conveniently redirected to a cached data of your site, that is milliseconds away from them. They will open the pages fast and will have a better experience.

Do you remember the time when we were reading the news in a printed newspaper and we were going to a video store to rent a VHS? The things have changed a lot ever since. Now you get the daily brief from an online portal and the content rental stores are all in the clouds. CDN is responsible for the global distribution of all that content. It makes it possible that all the viewers get their content in a matter of milliseconds, even if they live far away from the source.
Every media company who wants to be international relies on CDN. Youtube, Amazon, Netflix and many more can’t provide equal service in so many different locations without it. It can deliver quality 4k video without buffering (if the visitors have quality internet too).

Everybody uses CDN (content delivery network). YouTube, Amazon, Netflix and many others are applying it in a massive world scale so you can enjoy your favorite content in a matter of milliseconds. But how does it work?
Why do we need load balancing?
With the massive increase of the internet traffic each year, it is getting harder to provide a sustainable service for all the millions of clients without having some downtime. For this purpose, you need to apply a model of load balancing, that will reduce the load caused by the countless users trying to reach your website or use your application.
Another reason why you need to use load balancing is the rising number of DDoS attacks. To evade them you will need to spread the traffic to as many as possible servers that you have. That way, their combined efforts can resist the wave of high traffic.

Traffic director is a way to optimize and manage the traffic going to your domain by using geographical-based routing. Like this, your clients from Asia will get connected to your Asian servers; your European clients will connect to the closest servers they have in Europe and so on.
Traffic Director is a cloud-based implementation of Load Balancing (you can check our article on Load Balancing). It helps to improve the performance of your network. It can be incredibly useful for medium and large companies that need to deliver content to different parts of the world.
Some companies call this service traffic director, others global traffic director or GeoDNS director, but it is best known as GeoDNS, and that is why we use this term as the name of our service.

You cannot imagine the internet without DNS. There is almost no service that doesn’t depend on DNS technology. E-mails, VoIP, web services, all kind of CRM and ERP systems and much more. DNS is so important that we must take care of our network and make it as secure as possible.
Here we will show you some good practices to manage your DNS. Prevention is the best defense. Pay attention to these pieces of advice and take action.
Hide the master DNS
Configure the master DNS as a hidden. Like this, it will not be shown in the records of the name server. It will not appear, and it will not respond to any queries. Its purpose will be to give zone transfers to secondary name servers which will be public but doing it safely and hidden.

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.
