Top 10 Content Delivery Network FAQs You should Know About
The performance of websites has become a major factor for all businesses, and the term CDN has cropped up every now and then. Here are some of the popular questions asked about Content Delivery Networks and their answers you should know about.
1. What is the purpose of a CDN server?
A CDN ensures that your website is available to audience at different geographical location within minimum loading time. CDNs transfer data at a faster rate than normal, delivering reliable and stable page load speeds at different locations. Also, they help you in times of huge traffic by handling them more effectively than most of the other set ups. This can reduce scenarios where your website goes down.
2. How does a CDN solve the above problem?
A CDN is a network of globally distributed servers. It reduces the limitations of normal internet by storing and delivering cached static data whenever a user requests for the website.
This means that if a user requests for a page with 100 different elements and 70 of them are static (which usually is), then, the CDN will quickly load the 70 elements from a nearby location while the dynamic content would be delivered from your main server. This helps you save some precious seconds, delivering an improved performance for your website.
3. Can we use a number of datacentres across the globe for the same?
If you are going to use multiple datacentres, it’s going to take up additional time and money. It can be quite expensive to manage a network of datacentres. You will require a lot more resources and incur other operating costs. Also, it would take time to set up datacentres across different locations and build a network.
4. Is acceleration of dynamic content possible with CDNs?
Yes, acceleration of dynamic content is possible but all CDNs are not capable of the same. Usually CDNs only provide cached data for faster delivery and user experience but dynamic content acceleration is possible and is provided by tier-one CDNs alone which is set for the specific purpose.
In dynamic acceleration, data from the main server follows a direct path instead of accessing the usual internet nodes. Thus, there would be a significant decrease in page load time.
5. Do CDNs have any significance in Video Streaming?
Video streaming can be made much faster by accelerating the rate at which videos are delivered using CDNs. It also helps you to handle traffic surge more effectively.
6. I want my online store to have global online presence. Can a CDN help?
Depending on the size and reach of CDNs it is possible to provide your business a global presence. A large CDN might be able to deliver globally without any issues. But a smaller CDN would have limited geographical access. They might be limited to a particular region.
7. Would the mobile experience be accelerated with CDNs?
Yes. There are mobile CDNs to improve the mobile user experience. It is accomplished in 3 simple steps.
- Use text compression to reduce traffic for mobile data.
- Use video pacing to reduce excessive progressive downloading and finally
- Use TCP acceleration for making it suitable for the mobile user’s environment.
8. Does CDN enhance my site’s security?
CDNs have regular security checks and always try to meet the strict regulations in place. There are even cloud-related options to protect you from numerous security threats
9. What are the time and resources required for successful CDN implementation?
Both time and resources are dependent on your requirements. Usually, CDNs are relatively simple and easy to set up and use. When you start, they would already be configured to meet the standard performance needs. If you want to customize further, there are options for that as well.
10. How do CDNs help my business?
Faster websites mean better user experience. And with better user experience, you can retain existing users and hold the attention of new users. By reducing the load time, CDNs offer great opportunity for you to grow in the online business space.
