Content distribution network (Content Delivery Network, referred to as CDN) is a distributed network, which is established and covered on the bearer network, which is composed of edge nodes and cloud servers distributed in different areas. CDN shares the pressure on the origin server, avoids network congestion, ensures that the distribution of website content is accelerated in different regions and different scenarios, and improves the speed of resource access. Today, I'd like to introduce some reasons for using cdn acceleration.

Why use cdn acceleration? The purpose of using cdn is to accelerate the visit of the website, achieve cross-operator and cross-regional network coverage, ensure website security, backup in different places, save cost investment, and pay more attention to the business itself.

CDN acceleration stores website content on each node CVM, then parses the CNAME to the node control page through DNS, and selects the nearest node server by automatically distinguishing the user's region and network through CDN control. In this way, the cached content stored on the node server is displayed in front of the visitors.

So what are the benefits of cdn acceleration? What problems can be solved for website operation?

1. Greatly improve the loading speed of the website, reduce the slow opening of the page caused by the network and other problems, and improve the users' good impression of the website. You don't have to worry about the source of your website visitors, and you can perfectly solve the problem of data transmission across network operators. You can quickly open the website at any time, anywhere, any network operator.

2. The website cannot be accessed regionally due to various factors, such as the lack of interconnection, the limitation of regional ISP, and the limitation of export bandwidth. CDN acceleration can cover lines all over the world, cooperate with operators to deploy IDC resources, reasonably deploy CDN edge distribution storage nodes in the national backbone nodes, make full use of bandwidth resources, and balance origin server traffic.

3. CDN technology has high defense attributes, which can protect accelerated sites, greatly reduce the number of website attacks, improve the difficulty of hackers attacking websites, and improve site security. CDN's load balancing and distributed storage technology can enhance the reliability of the website, virtually adding an umbrella to your website to deal with the vast majority of Internet attacks.

4. When a server fails unexpectedly, the system will call other nearby health server nodes for service, thus providing nearly 100% reliability, so that your website can never go down.

5. Greatly reduce the overall input cost of the website, whether it is the early investment of the website server or the later operation and maintenance cost will be greatly reduced. Cloud service-level CDN technology is also much lower in price than traditional CDN.
