Understanding Content Delivery Network (CDN) in a Simplified Way: Your website speed is an important factor when we specifically talk about the importance of a website and the essential features of it. When your website has a quick loading speed then the visitors are retained and kept engaged on the website. Better bounce rates, usability, and higher traffic are some of the points which ensure that Google ranks your website in a better position due to good authority. What a website needs to load faster is high-quality hosting service and constant availability. The location of your website hosting provider matters a lot. As websites have a lot of content in them, it is important that a website should be able to load faster and display all the content on time.
There are still a lot of people who do not clearly understand the importance and benefits of CDN for their website. It is essential to know the advantages of this service and so we are further going to see the types of CDN and its benefits.
The various types of CDN are as follows:
1. Peer to Peer CDN
Here a Peer to Peer protocol is used where no caching is involved and the users are also a part of CDN. When there are other users, the content is shared and while downloading the contents they also upload without affecting the browsing experience.
2. Push CDN
In this type of CDN, the content is manually pushed to the CDN servers. These servers act as secondary server to the main server. If you have a static website with huge downloadable files then this is the best choice.
3. Origin Pull CDNs
In Origin Pull CDN, the contents are stored in some of the web servers and not all. There is no need to physically upload contents to the CDN servers as the CDN itself pulls the content from the main servers. When a user has some specific request, the nearest CDN will provide the content to that individual. This type of CDN is suggested for WordPress blogs.
It is essential to know what type of benefits you are going to receive when you choose a particular type of CDN. The benefits mentioned below are not divided based on the type of CDNs because there are obviously different types of benefits which the CDNs offer and so these are the general advantages which I have mentioned.
Benefits of Content Delivery Network are as follows:
1. Improves website’s loading time
When the CDNs are distributed geographically, they are strategically present in almost every area. So when a visitor tries to open a website then the nearest CDN provides content to the visitor for faster website loading. User do not want to invest their time in a website which is slow and unresponsive and thus due to a CDN server located nearby, there are no chances of a slow website.
2. Lower Bandwidth Costs
Bandwidth consumption cost is a separately chargeable amount from the hosting provider. So caching data through CDNs are able to reduce the amount which the main server should provide and thus this reduces the hosting costs.
3. Higher Content Availability
Thanks to the distributed nature of CDNs, it is able to handle more traffic and can also withstand failures because there are multiple servers and so the content is always available to the website owner.
4. Enhances website security
DDoS Migration is provided by CDN which improves security and other related optimizations.
5. SEO Benefits
Google selects those websites whose site speed is high compared to other websites and then it includes it in the SERP algorithm which downgrades another website with slow loading speed.
6. Low Resource Usage
Very low resources are being consumed by the main host server because the contents can be fetched through the distributed CDN instead of connecting every time to the main server.
7. Reduced Bounce Rates
When you have a fast loading website then the visitors are kept engaged which results in low bounce rates. In case if you have a slow loading website then the number of visitors your website receives will be lowered because no one wants to invest their time in a website which takes forever to load.
Here are the steps one needs to take for a suitable selection of a CDN:
The most important thing to know before you buy anything is the requirement of that product or a service. A peer-to-peer CDN is used for a website like a torrent, a push CDN is used by a website which has images, videos and downloadable content and lastly an origin pull CDN for a WordPress Blog website which has distributed traffic around the world. Understanding your need before you go for a CDN is important.
Different types of CDNs offer you different types of features and they offer Add-ons as well. Real-time statistics, Custom Cname, Firewalls and many more Add-ons are offered by various CDN providers.
Comparing CDN providers should be obvious on your list because there are dozens of providers in the market and you need to ensure that you select the best CDN at the most appropriate price possible.
We have been hearing everyone say ‘Content is King’ only due to the fact that it is an important factor and we cannot ignore the fact. So going for the right CDN will definitely ensure that your site is rated higher among visitors and search engines. A good responsive website is always rated higher as compared to websites which are hardly available when you search for them, they don’t have informative content and loads at the speed of a turtle.
