Since CDN (content delivery networks) appeared on the market, acceleration of websites has become so much easier! Not so long ago, this solution was available for top dog companies only. Today, there’s a full spectrum of budget-friendly solutions for web developers and enterprises that come with additional features and pay-as-you-go pricing policy. Those made us face the agonies of choosing: the number of worthy providers is overwhelming! Let’s get into the nitty-gritty of CDN and learn about 5 great providers recommended by INXY.HOSTING.
When to use a CDN?
CDN is one of the most promising Internet technologies that is expected to transfer more than 60% of global content by 2019. However, it’s not equally useful for all projects. Keep in mind that the simpler is the better: extra features may come at the cost of excessive complexity and higher vulnerability. Besides, websites with target audience in a single region won’t reap benefits from CDN – it can only make things worse. Key advantages of CDN are:
- Higher speed, especially for distant end-users;
- Load balancing and delivery optimization (less bandwidth and CPU, storage and traffic);
How CDN works?
The main operating principle of content delivery network is to reduce the distance between local visitors and servers. Content is delivered quicker, when served from a closer location to the visitor. Therefore, the more PoPs (points of presence) comprise a network, the better. Edge servers included in a CDN cache not only heavy assets (images), but also JS, CSS, fonts and sometimes – full versions of pages. That decreases latency and round-trips (RTT) and offloads the main application web server.
Push & Pull CDNs
Traditional CDN solutions work as push CDNs, which means you need to upload website files to it. The main advantage of this variant is overall control over your media.
But the most advanced web-masters implement pull CDN (reverse proxying). Why? It eases the task: the images are to be uploaded locally, on the main server only, and they they’ll be pulled on the CDN automatically. Leveraging a pull CDN is a piece of cake: you will easily find plugins for your CMS and example configurations for your framework.
CDN functionality is confined to website acceleration only: such network also adds up to performance and security. CDN hosting often comes with:
- Image optimization, GZIP compression and conversion to webp;
- Cache header optimization;
- cache purging after alteration of files;
- DDoS protection and firewall;
- HTTP/2 delivery;
- video streaming;
- TLS (SSL, HTTPS).
Combined together, these services can make things much faster. But while ordering a CDN with extra perks, don’t forget to keep your code clean: it’s the main condition of a fast website. Keep your technical stuff simple: don’t congest your website, or CDN benefits will be decreased almost to a zero. When you decrease load time, it will lead to increased conversions, sales and SEO.
