What Is CDN & Why Is It Necessary

When we talk about increasing our website’s security and speed, CDN is what comes first to our minds.

CDN Definition

CDN Is Actually an Abbreviated Form of Content Delivery Network. The thesis begins On the Rage of Traffics. CDN Helps websites with a large Amount of Traffic to Easily Increase their reach and loading Speed. CDN Helps in reducing Traffic loads on a Single server by Dividing the traffic into numerous Small Servers. CDN Also Helps In reducing Bot Traffic, In most cases, it Almost eliminated the Bot Traffic from reaching the servers.

Having The High load on a single wooden plank will Break it, But When Divided into 2 or more, It’s Strength Increases. The same happens when we talk about servers, When your website starts to engage more and more traffic, there will more load on a Single Server To Process the traffic Accurately and de delivers Speed and Sustainable Connection. CDN Is used to Divide Traffic and Increase Sustainable Connection and Speed.

If Someone Visits this blog from the USA and India at the same time, my Server has to manage both of them at once. With CDN Activated The Visitor From USA Will be redirected To The Closest Server possible and the user form INDIA will Also Be redirected To Closest Server. Doing this No Sever is overloaded and Your Website is easily Accessible.

Your files such as images, pdf and other documents are then served by your CDN partner so that you don’t have to worry about server loads and low response rates.

Benefits

CND Providers like StackPath provide excellent Protection against Bots. This helps in giving more importance to Genuine Traffic and Reduce The Load.

However The Famous Free CDN provider Cloudflare Also Gives protection against bots, They have been reported to Be very Undefined. Sometimes they Show A reCAPTCHA to Some genuine user creating a pathetic impression and Making them Not to visit your site again.

Google has clearly stated that the faster Sites get higher Rankings.

Website owners including me, have seen increased Engagement, Reduced Bounce Rates and Better Ranking After Using CDN. This clearly Shows Faster Sites creates Great Impressions on users

Reduced bandwidth and traffic cost. This is one of the major benefits of using CDN.  If you are using shared hosting or a limited bandwidth hosting plan, implementing a CDN can have a great impact on your bandwidth cost. Moreover, you won’t have to pay for spam and bot traffic.

If in any case, your website starts to get more traffic than usual, a CDN would prove to a boon for you to handle that traffic without crashing your servers.

It also helps you by protecting your site from future DDOS attacks, brute force attacks, spam attacks and heavy server loads that may break your site.

You don’t want your visitors to flee away before they read your content and a CDN might help you increase page views and decrease bounce rate to a great extent.

Best Services

Free and paid CDN Provider – CloudFlare
Paid And Premium Services – StackPath and KeyCDN

We prefer using StackPath or KeyCDN above free Cloudflare CDN because the User experience and reliability Are Greater and better. These two CDN(s) Are the best and You Will be getting Best in class Services.

Cloudflare gives free CDN and a free SSL certificate too. As a beginner, they are the best choice. However, MaxCDN is better when it comes to a paid version.

KeyCDN gives its users a free trial of 30 days. You can use this period to judge if they are the right choice for you or not.

I also recommend implementing Sucuri Firewall for enhanced security and preventions from hacks. A firewall will help you decrease your server load drastically, I use Sucuri, and I feel they are the best.

The cache plugin W3total cache and WP Rocket, both have a CDN integration option in their plugin settings which makes it very easy for you to handle cache and delivery networks while maintaining a balance between them.
