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.

Benefits

  • 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. 
DNS

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?

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.

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.

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

Conclusion. 

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. 

Conclusion.

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!
