Web professionals rely heavily on two essential elements for achieving an excellent online experience for end users: performance and security. Omitting these necessary features will likely result in flawed functionality and slow website loading times. Additionally, keeping the website secure from malicious activities not only benefits the website owner, but also increases the safety for the site visitor. Content Delivery Networks (CDNs) are used to enhance speed-to-delivery as well as security providing a great solution for both of these needs.

It is suggested for Web professionals to find a reliable Web hosting solution that is accompanied by a reliable CDN, all within one package. Having multiple points of presences around the world, CDN infrastructures allow for static data from websites to be stored on the local networks. This process is often known as "caching." With this, requests can be completed very quickly, drastically reducing latency for content delivery so visitors, no matter where they are located, can experience optimal performance of a website. While the static content is safely cached in the CDN locations, dynamic content is often still delivered directly from the host's servers along with all master copies which remain in the data centers. 

In addition to speed, a reputable CDN solution can deliver great protection for websites. Online threats are often a main concern for all Internet users - professionals and individuals alike. Intelligent protection mechanisms are put in place by large CDN providers, such as CloudFlare, for security against spam attacks, SQL injections and DDoS attacks in addition to excessive and unwanted crawling by bots helps to keep sites secure. CloudFlare’s technology automatically detects new attacks against any and all websites on its network. Once the attack is identified, they begin to block it for both the particular website and the entire community. This ensures that all users of their network are constantly being protected against the latest online attacks.  

Web professionals often feel that a reliable Web hosting solution often comes with compromised loading speeds or security. The implementation of CDN technology into a reliable Web hosting portfolio provides a unique and beneficial environment for all projects online.
