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.

The recent Black Friday we again saw the news for record-breaking revenues and profits. Over the past few years, the web has gotten faster, according to Google, 53% of users will abandon a site if it doesn’t load within three seconds. By this, you can guess that for a shopping site, the speed of the website reflects its revenue. So, we want to see whether e-commerce sites got faster as well?
The DDoS attacks are also increasing. According to Kaspersky Lab 33% of organizations experienced a DDoS attack in 2017, compared to 17% in 2016. So we also want to know if the top shopping websites are well prepared for future attacks.

But to be protected, we must know the danger.
DDoS attack (denial-of-service attack). There are few different types, but in general, a DDoS attack is an attempt to overwhelm the target (a computer, few connected computers or a whole DNS network) with high traffic from multiple sources.

For many years already, the Unicast protocol has been outdated for the purpose of fast and secure DNS. It can’t manage with massive DDoS attacks, can’t handle load balancing in different locations, and it is quite slow for a global presence. But don’t get desperate, a new technology is there to help you out.
So what can you use to provide fast and reliable DNS?
Anycast DNS is here to step in. It is by far superior technology! It reduces latency, give extra security and minimize downtime.

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.

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 188.8.131.52.
