Why should you use a CDN?

Summary: When you choose to use a CDN, what are you doing?

If you are running a website, you should know that several factors are the key to your success:

attractive content, fast
access speed
, support for frequent user
interaction , accessibility from anywhere In
addition, your website must be able to operate in a complex network environment, taking into account the global user access experience. Your website will also grow in size with the use of more and more objects (such as images, frames, CSS and APIs) and various actions (sharing, tracking). Therefore, the slowdown of the system brings about the loss of users.

Research by Google and other sites shows that for every second a site is slow, many visitors are lost, and even those visitors never return to those sites. As you can imagine, if the website is your profit channel or brand window, then the slow website speed will be a fatal blow.

This is the first and most important reason why you use CDN: **In order to speed up website access**

In addition, CDN has some functions:

1. In order to achieve cross-operator and cross-regional network coverage

Interconnection Various factors such as non-interconnection, regional ISP geographical limitations, and limited export bandwidth have all caused the regional inaccessibility of the website. CDN acceleration can cover global lines. By cooperating with operators, deploying IDC resources, and reasonably deploying CDN edge distribution storage nodes in backbone node providers across the country, making full use of bandwidth resources and balancing source site traffic. Alibaba Cloud has 500+ nodes in China and 300+ nodes overseas. Covering mainstream countries and regions is not a problem, and it can ensure the stability and speed of CDN services.

2. In order to ensure the security of your website,

CDN's load balancing and distributed storage technology can enhance the reliability of your website, and virtually add a protective umbrella to your website to deal with most Internet attacks. The anti-attack system can also prevent the website from being maliciously attacked.

3. For remote backup

When a server fails unexpectedly, the system will call other nearby healthy server nodes for service, thereby providing nearly 100% reliability, which allows your website to never go down.

4. In order to save cost and investment,

the use of CDN acceleration can realize the nationwide deployment of the website. You do not need to consider the purchase of servers and subsequent hosting operation and maintenance, mirror synchronization between servers, and you do not need to worry about managing and maintaining technicians, saving manpower and energy. and financial resources.

5. In order to let you focus more on the business itself,

CDN acceleration manufacturers generally provide one-stop services. The business is not limited to CDN, but also supporting cloud storage, big data services, video cloud services, etc., and generally provides 7x24 operation and maintenance monitoring support , to ensure that the network is open at any time, you can use it with confidence. And put more energy into developing its own core business.

The above is the reason why you use CDN. If you have any omissions, please leave a message to add
