Why Your Website Needs a CDN
Although a somewhat simple idea, content delivery networks (CDNs) have a great impact on the performance of websites. A lot of businesses are enjoying the benefits associated with having their website hosting infrastructure fully optimized by a CDN, and listed below are few reasons why it is important to consider deploying your digital property over a CDN.
Faster delivery as well as load time
The most effective function of a CDN is to reduce the distance between website visitors and a website’s server, thereby minimizing latency and boosting site rendering performance and speed. This is achieved by storing a cached form of content (such as rich media, downloadable files, and scripts) in servers all over the world.
Once you’re making use of a CDN the content will likely be offered to the site visitors from the node closest to their physical locations. By doing this, the data does not need to travel through many nodes to get to a website visitor thereby speeding up the content delivery period.
It is essential to keep in mind that the rate of success of this method relies on your CDN provider’s data center regions. For instance, if you’re an international company with a huge percentage of clients from the East Coast, it’s vital that your CDN provider has the ability to deliver swiftly to this specific region. Ensure that you check with your webmaster before deciding on one.
Use browser caching
Some typical elements seen in websites already are hosted at no cost CDNs run by tech leaders like Yahoo and Google. The best example of this kind of content is jQuery fonts and files. Because many sites use these, most likely the visitors that come to your site already have these types of files cached in their web browser. This reduces the volume of requests to your server and assists speed up your website’s loading time.
Support various connections
The majority of browsers limit the amount of concurrent connections from one specific host. Therefore, if there is an amount of file requests, it will take some time for all of the files to be loaded by the browser.
In content delivery networks, files are served from various domains, enabling you to have many concurrent connections thus enhancing website load time.
Offer assistance for content optimization
In a society in which a 1-second hold up in load time can easily cost you potential business, it’s crucial that you serve your content as soon as possible.
Because serving content is their business, content delivery network providers by default give a lot of choices to optimize your content delivery.
Popularly known as front-end optimization, this consists of features such as
• Image optimization
• Code minimizing
• File compression
Also, you can further enhance performance by using things such as CSS sprites as well as using Vector images rather than Raster images (that helps with responsive design additionally).
Each one of these factors contributes to improving site loading speed, which is essential in optimizing your site’s search ranking, much like Google. Not just that, but having a quick loading website results in a better consumer experience, that in turn will assist you to retain customers and increase sales.
Enhance dependability and scalability
If it’s possible for you to lose potential customers for a 1-second delay, just imagine the amount of money you can lose if your website is down for an one hour.
Because the content is spread across many data centers, there will be redundancy. This means that even if a single data center goes down for whatever reason a CDN will automatically direct clients to obtain files from the other CDN network nodes.
Additionally, delivering content and media from CDN nodes implies that you save on bandwidth utilization from your main website host, reducing the chance of excess load or consumption, which can at times lead to crashes or overage.
The price of a CDN as well depends on region reach, bandwidth, or security/SSL requirements. For instance, if you find that many of your users are from North America and Europe, you can forget about buying server nodes in Asia.
Content delivery networks don’t need to be cost prohibitive, and can easily be available to site owners of different budgets.
With site loading speed and uptime becoming important for many businesses, a CDN provides you with a simple way to enhance the performance of your site.
