Content Delivery Network (CDN) – beginner’s guide

Content Delivery Network (CDN) is great and beneficial. In present days the need for fast and reliable access to any type of content is crucial. That is why it is more important than ever to understand what actually stands behind it. So, let’s take a minute to explain a little bit more about it. 

Content Delivery Network (CDN) explained.

Content Delivery Network (CDN) is a complex solution that focuses on delivering content to clients quickly by applying routing and cache mechanisms. The servers are positioned in very precise locations and cover a wide geographical area. They cache the data (code, videos, images), and the aim is to be as closer as possible to potential visitors. As a result, the clients receive reliable, fast service. In addition, CDN acts as a load balancing mechanism that is going to reduce the pressure on the primary server.

How does Content Delivery Network (CDN) work?

CDN requires an extensive network of servers for caching the data, content that will be spread to particular customers in various locations. Therefore, a well-established infrastructure is key. For that reason, CDN providers determine their PoPs strategically. They analyze the Internet exchange points (IXPs), the physical infrastructure that Internet service providers (ISP) use. On those precise IXPs, speed and placement are the most beneficial. The providers of CDN have to make a decision because having PoPs in each of the possible IXP is going to be very pricy.

Next, thanks to the GeoDNS tech, the visitors of the website are connected to the nearest and fastest server. Moreover, this valuable connection is not relying on receiving the data from the web hosting. It saves a lot of time, which is crucial for these businesses.

Content Delivery Network includes the usage of infrastructure that already exists, and these providers do not own.

CDN providers offer their services, and their customers use them for delivering their content to their users. Yet, CDNs make payments to the carriers, Internet service providers, and network operators for utilizing their data centers to host CDNs’ servers.


  • Great speed. The request of the users travel in a short distance, and their answer is provided quickly. The nearest secondary server which has the content available in its cache provides it to the user.
  • The efficient and quick response does not depend only on web hosting.
  • CDN PoPs are placed on IXPs, and for that reason, you have the advantage of high speed and strategic position. Your users can access your content quickly and accurately each time they want it.
  • Improved uptime. Thanks to the many servers that cache the information, if one of them experiences difficulties or is down for some reason (maintenance or attack), the rest will be able to respond. 
  • Less bandwidth. The majority of the request of the users are going to be handled by the secondary servers which are near them. So, the primary server is going to be in need way less. If you think about simply the bandwidth that videos need to be loaded, that is not an unimportant advantage at all. 

Cloud DNS hosting – How can you benefit from it?

A cloud DNS hosting is one alternative the businesses have to store their DNS records and be available online, instead of hosting them on their own DNS servers.

It’s already a popular choice, and definitely, it has interesting advantages in store for you. So let’s see how you can benefit from it?

Benefits of a cloud DNS hosting.

Get the necessary PoPs for your business.

This is a very important benefit, especially for international online businesses. A cloud DNS hosting providers have large networks for supplying you with the most attractive and strategic points of presence (PoPs) globally. You just need to choose and add the PoPs that get you closer to your target market!

Speed up DNS resolution for your business. 

A quality cloud DNS hosting providers offer you really robust networks. We talk about many name servers located around the world at your disposal. This is exactly what you need for speeding up the DNS resolution for your domain. And remember, the closer to the place where the request for your domain was sent, the faster response time. And less latency or waiting time for loading a site means happy clients and profits for you!

Get modern and reliable infrastructure.

Your business can rely on secure, modern, and efficient software, hardware, and experts. You can access a solid infrastructure to operate your business with a very narrow chance of failure. Besides, you will save money because it’s not you directly buying and maintaining all these attractive assets.

Scale up or down, based on your needs.

Every business looks for constant growth. But to grow brings bigger needs for your business (security, speed, PoPs, etc.). To expand or reduce your resources can be expensive if you don’t have accurate calculations. A cloud DNS hosting makes this easier because you can add or cancel features based on your real needs without compromising your budget. There are plans and possibilities for all types and businesses sizes.

Add redundancy, and increase uptime.

Redundancy means the difference between being available online consistently or not. And a cloud DNS hosting is an efficient way to gain it. Having your DNS records saved in more than one server, you don’t have to worry about downtime if a server fails or suffers an attack. For sure, another server from the network will serve the clients’ requests. Higher uptime represents a good experience for clients and more money in your pocket.

Strength your security. 

A cloud DNS hosting providers offer you security features. Some even supply you with an anti-DDoS technology. But in a basic way, Cloud DNS hosting by nature offers servers enough for balancing your traffic loads, and that can be helpful to prevent or mitigate such online threats.

It’s easy to use.

To be an administrator is a tough job. A cloud DNS hosting simplifies the management of a domain, it supplies a friendly panel to execute tasks easily, and it’s in charge of maintenance and other routine tasks. As a result, you can focus on critical missions for your business. 

Customer support.

Terms, conditions, schedules, and ways to contact the support team depend on every provider, but usually, the providers offer good customer support. 


A cloud DNS hosting offers real benefits for you and your online business. Check your website needs, budget, and different quality providers to make the best decision.

DDoS attacks

​5 Best Practices for Mitigating DDoS Attacks.

DDoS attacks keep multiplying in a scary way. Statistics clearly show their power to disrupt and damage all types of online organizations and businesses. Currently, there’s no way not to be 100% prepared!

5 Best Practices for Mitigating DDoS Attacks.

Prepare a static version of your website.

If you get ready with this static version, you will have an alternative destination to send your traffic if your site goes down because of the attack.

Besides, static versions offer other advantages. They improve the speed of loading the site. They take less bandwidth and processing power, and this will decrease the strain on your servers.

There are different ways to create your static website version, but they are up to the web hosting platform you use.

Get AI as a security tool.

DDoS attacks dimensions, speed, and the fact that they can be implemented during not working hours or days limit the humans’ response. Based on the knowledge of the constant traffic patterns and other indexes like bandwidth consumption, speed, etc., artificial intelligence (AI) can detect and take actions against a DDoS attack. Whenever is needed, AI can block accesses from suspicious spots, execute distribution of traffic to relieve the attack server’s load, for it not to crash, monitor non-stop, and so on.

Choose multi-layer DDoS defenses.

DDoS attacks have evolved a lot, getting more and more harmful. In the past, they used to target mainly the network and the transport layers. But currently, techniques and the combination of them can target other layers, too, like the application and the session layers. 

Every layer involves different functionality. So get DDoS protection that offers proper defenses on multiple layers to fight back the criminals well.

Limit the attack surface.

To limit the surface for criminals to attack your business means to reduce their chances (entry points, servers, ports, protocols, etc.) to reach your vital assets. You can enable this best practice for mitigating a DDoS attack through different strategies. Here there are some examples:

  • You can protect your servers and other resources by putting them behind the load balancers. 
  • Frequently, applications or websites keep irrelevant or unnecessary features, services, legacy processes, etc. Remove them all, and you will close possible entry points for attackers.
  • A content delivery network (CDN) service combined with a web application firewall (WAF) put on the network border can stop direct access to the server and resources. Content is cached on servers located worldwide, and requests are served only from them. Requests of content that hasn’t been cached have to pass through the filter (WAF). 

Strength your network architecture.

What you need is to transform your regular network architecture into a robust one capable of resisting a DDoS attack. This involves getting proper weapons to fight back the attack and mitigate it as much as possible. Consider having wide bandwidth, a load balancing mechanism to handle huge traffic loads, and sudden spikes. Get enough DNS servers strategically located to rely on if a server goes down because of the attack. This redundancy will avoid disruptions to the service. 


Talking about DDoS attacks, prevention is the best practice. But if it fails, you still can be prepared to mitigate them. Seriously consider these 5 best practices for mitigating DDoS attacks. They could save your online business!

The best TLDs for international businesses.

Online competition is too hard! To be visible and memorable among millions of domain names that already exist is a massive challenge. There are different factors to consider for building a successful domain name. Today we will talk about the best TLDs for international businesses. Yes, a TLD can make the difference! 


The .com (commercial) is one of the TLD pioneers on the Internet. It was created for commercial websites and implemented in 1985. After more than three decades, it has built a trustable reputation, and it’s still a solid card to play to bright on the Internet. It’s not tied to rules or conditions. It’s open for everybody interested in registering it. Time ago, not only commercial but also nonprofit or private individuals could use it.

It has really been ingrained in people’s minds. Just think how many times, while requesting a domain name, you have instinctively typed .com? 

.com is a high demanded TLD. Therefore, availability could be an issue.


The .net (network) is another open TLD people or entities can register. It was created for domains related to a computers network or umbrella websites working as portals for smaller sites.

Users’ perception of it is positive. It provides credibility, trustability to domain names. It has been around long enough for people to remember it. So it’s a strong choice for your international business!

It’s ideal for businesses that offer services or tools linked with networks, ISPs, databases, web hosting, etc. But all kinds of industries are using it due to its global popularity.


The .store is becoming popular. It’s short, strong, and very intuitive. Obviously, it’s a great alternative for e-shops, but all types of services are currently using it. Users have well-accepted it, and it shows good levels of memorability. It can perfectly work for your international business.


Created for professions or professionals, to associate your international business with this TLD can be a good decision. It implies that you are an expert, a leader, a person, or an entity with the right experience in your specific field to be reliable. Your domain name can combine very well with .pro.

Its use is not restricted to certain professions. To be recognized around the world as a professional in your field is totally positive. You can get the trustability people to look for. If you want to try a fresher TLD, .pro is a very good choice!


This .global TLD clearly states your business’ size and purpose of being present all around the world. No matter the industry or business you own .global is strong, clear, trendy, short, and easy to remember. It’s open for registering for anybody interested. The association of your domain name with this new TLD has all the potential of being a winning combination.


Biz is a short way to express “business”. Especially on the Internet, the use of abbreviations for words is very common. In that sense, biz to mean business is widely used. The TLD .business exists too, but .biz sounds fresher and innovative. If this is the kind of image you look for for your online business, .biz can be a great match.

It’s not restricted to specific industries or businesses. It’s easy to remember. From first sight, people will know you are ready to do business!


The TLD can boost or affect your chances of being found online. And it also influences people’s perceptions about your business. Choose it wisely!


How can GeoDNS improve your performance?

What is GeoDNS?

You can find GeoDNS, also called global traffic director, or just traffic director. It is an effective approach for optimizing traffic to domains by implementing geographical-based routing. Additionally, it is considered a cloud alternative for load balancing. It has a positive effect on the performance of the network.

If you are running a business that distributes content all over the world, you could definitely benefit from it. GeoDNS provides you nameservers that are strategically positioned throughout the globe plus an efficient way to spread the traffic regarding queries’ locations.

How does GeoDNS work?

To start using GeoDNS, you want a DNS provider that supports Geolocation. Once you start implementing it, the DNS server is going to look for the location of every user’s query that is received. DNS checks the user’s IP address and searches for the location in the database. Then, the name server is going to send a pre-configured record defined explicitly for the country where the query arrived from. After GeoDNS identifies the query’s location, it determines the best and faster route to respond.

It utilizes DNS GeoIP searches to direct customers to the best server option, in other words, the one which is the closest location. As a result, every server will have different IP addresses for the corresponding domain. 


Enabling GeoDNS for your domain provides some clear advantages.

  • Optimized traffic distribution

With GeoDNS, it is possible to manage the traffic wisely. It is a great solution for load balancing. It guarantees that the nearest nameserver will respond to the request of the visitor. Moreover, through this distribution, traffic overload is easy to avoid automatically.

  • Improved loading time

Quick loading is essential for improving the users’ experience and a critical factor in ranking in search engines. Moreover, based on the intelligent location method of GeoDNS, waiting time for sure is going to be lower for your visitors. That is already significant advantage. However, now that a positive user experience is also considered to be placed in the first search results, the gain is even more precious.

  • Improved uptime

Having a group of DNS servers is a great privilege. In case one server is down, the user’s request for sure is going to be resolved from one of the other servers.

Through IP filtering, you can deny access or direct users from a specific region. Let’s take, for example, a singer contracted exclusively with a British company. When there is a release of new songs, access to them can be restricted by IP filtering only for British users. IP addresses that are from other countries are going to be dropped.

Who can use it?

There are no limits when it comes to who can benefit from GeoDNS. All types of organizations could find it helpful. For instance, small websites that want to expand could like to use it. On the other hand, probably the biggest need of it has the large businesses to achieve stable process. It is considered that international organizations that handle a lot of traffic could get the most out of it. 


Why should you choose Anycast DNS?

Anycast DNS explained

Anycast DNS is a traffic routing mechanism that delivers content fast from websites. It uses multiple nameservers that hold one individual IP address. 

Every one of the servers is located in a separate geographical location in order to be as close as possible to the users. The reason for that is to achieve a faster response to the request, which leads to a better user experience. The server that is nearest and available to the client requesting the website is going to answer. Any possibilities for latency are reduced to a minimum. Your website is easily reachable, and customers won’t wait long to connect with it.

Additionally, if the nearest server it’s not working due to maintenance, for example, another server, the next closest, is going to answer. 

Anycast DNS manages requests by the quickest route. For that reason, your domain’s resolution time becomes very еxpress. 


  • Easy setup – You just have to configure it in only one server. Additionally, such settings can be expanded to the entire network.
  • Improved response time – With directing to the closest available DNS server, the response time is reduced.
  • DDoS protection – In case a DDoS attack appears, only a piece of the whole Anycast DNS group of servers is going to experience it.
  • Reliability – Implementing Anycast improves DNS reliability by establishing many servers in different locations with identical IP address. As a result, the service is more highly available and reliable because of the redundancy of the DNS servers. 

Why should you choose Anycast DNS?

If you are running an international business and your online presence is crucial, Anycast DNS is a great opportunity. Additionally, if you provide a service and you want speed and reliability in every location, you can benefit a lot from this type of routing mechanism. 

Anycast DNS manages the traffic in the most efficient way, plus your customers will be happy to reach your website easily. The improved network converts into a great experience and more sales.

Anycast DNS and CDN

Anycast DNS is a perfect choice for Content Delivery Network (CDN). The reason is its ability to quickly respond to queries and directing the traffic to a close local server.

Let’s picture an example network, where we have customers from 3 different continents: Europe, Asia, and North America. So, we established three copies of the website on three separate servers with different IP addresses. On every continent, we have set up Anycast DNS servers. So, therefore, all the traffic in North America is directed to the DNS server there. The traffic in Asia is directed to the Asian server, and the same runs for Europe.

The CDN is going to reduce the latency significantly for two reasons.

  • First, the Anycast DNS servers are as close as possible to the customers. They are positioned in each continent and even probably in each needed country. The domain is going to resolve very quickly.
  • Second are the several copies of the website. Thus, you are not just responding to the domain name query faster, although you can also manage the traffic to a closer web hosting.

When you combine these two, the customers are receiving the best experience. If the nameservers and web servers are located on different continents, the users will face latency for sure.
