What is a CDN?
A content delivery network or CDN is a geographically distributed network of high-performance servers that are connected together, to deliver content to clients from the server locations nearest to the client location.
How does a CDN work?
A CDN is basically a network of globally distributed servers that are connected together with the intention of providing content as easily, cheaply, effectively, and safely as possible, to the clients. A CDN would position servers at the points of exchange between various networks to increase speed and connectivity.
These Internet exchange points (IXPs) are the primary locations where separate Internet service providers link and provide each other with access to traffic originating on their respective networks. A CDN provider can minimise costs and travel times in high-speed data transfer by connecting to these high-speed and heavily interconnected locations.
Apart from the location of servers in IXPs, a CDN optimises regular client/server data transfers. CDNs locate Data Centers in strategic locations around the world, improve protection, and are designed to withstand different forms of disruptions and Internet congestion.
Why should a CDN be used?
Content Delivery Networks or CDNs help bloggers optimize the page load times of their blogs. Here are how CDNs help.
Latency: When it comes to a website, loading content within the shortest time is important and if that doesn’t happen, visitors leave easily. CDN services can help bring down page load times in the following ways:
-Hardware and application optimisation, such as efficient load balancing and the latest of solid-state hard drives, can help data reach the user quicker.
-CDNs can reduce data transfer by minimising file sizes by techniques such as minification and file compression. Smaller file sizes mean much fewer data to transfer and faster page loads.
-By optimising connection reuse and allowing TLS false start, CDNs also accelerate sites that use TLS/SSL certs.
Bandwidth: Server Bandwidth is utilized every time an origin server responds to a client-side request, to provide access to content stored on it. A CDN, such as Bunny CDN or Cloudflare CDN helps bring down origin requests and bandwidth usage by serving the requests through their servers.
Safety: A CDN’s information management system is an essential component of data security within the network. A CDN can keep a site safe by renewing TLS/SSL certificates, ensuring a high level of security, encryption, and honesty. Examine the security issues surrounding CDNs and what can be done to distribute information safely.
What are the best CDN services out there?
Here are the top 5 CDNs for WordPress websites:
Cloudflare CDN is the most prominent and widely used CDN among bloggers, small businesses, digital marketers and professionals. It comes with a free plan with no restriction on bandwidth. As a result, it is one of the strongest free CDN providers for WordPress.
They have over 180 data centres all over the world. This will help you boost your website’s efficiency, pace, and protection.
Cloudflare is simple to install on a WordPress blog. It automatically archives the website’s tools, once the configuration is done. You can, however, clear the files from the control panel if you choose and generate a fresh version of the website, with a click.
One disadvantage of Cloudflare is that, unlike other CDN providers such as StackPath and Sucuri, you must switch to a premium package to access all of their security features.
BunnyCDN is a lightning-fast CDN service with the best and pocket-friendly pricing that can help the website speed up internationally, and not burn a hole in your pocket.
Bunny CDN is a performance-focused organisation based in Slovenia that was established in 2015 by a group of professional and enthusiastic teams with over ten years of experience in CDN and other technologies.
With major rivals such as Cloudflare and KeyCDN. BunnyCDN is here to help you make your web quicker with global latency of less than 30 ms.
KeyCDN is another well-known CDN service provider on our list. Using the CDN Enabler WordPress plugin, KeyCDN can quickly be added to a WordPress blog.
Customers can easily sign up for the “pay as you go” option, which means the billing is purely based on usage. KeyCDN is an ideal CDN for low traffic websites to get started with a content delivery network, but the pay-as-you-go billing model makes it sort of unfavourable, once the traffic grows.
KeyCDN stands out from among the competition, by offering a host of features like Gzip compression, real-time traffic and usage reports, instant cache purge, 2FA, DDoS attack security, and many others.
Google Cloud CDN
Google Cloud CDN is the affordable content delivery network that makes use of Google’s global infrastructure. They have data centres in 90+ countries.
It includes a free SSL certificate to help protect the website from attacks and improve security. It can also be integrated into the Google Cloud Platform.
This is the best part, where you can claim $300 worth of free trial credit to try the feature-rich Google Cloud Platform.
StackPath is a top CDN provider in the industry. It includes many data centres around the globe, allowing you to optimize the loading speed of your website. Furthermore, it includes a private EdgeSSL certificate as part of its package for free.
Stackpath is simple to configure and helps you to track real-time analytics. It also includes features such as intelligent caching, Gzip compression, 301 redirects, and many more.
StackPath provides extended security services like load balancing, DDoS support, a firewall, and more, in addition to their stellar CDN. This is something that other service providers lack.
