Ordinary servers and CDN (content distribution network) servers are two different types of servers for different purposes. They have some important differences in functions and uses.

　　Ordinary server:

　　Ordinary servers usually refer to conventional servers for storing, processing and providing websites, applications and services. They host websites, databases, application logic and various data. The following are the characteristics of some ordinary servers:

　　Resource concentration: Ordinary servers carry all resources of specific websites or applications, including static and dynamic content, databases, images, videos, etc.

　　Geographical location: Ordinary servers are usually located in specific data centers or server architectures, and their geographical location is fixed.

　　Network delay: When users request data from the server, network delay may affect the response time, especially when the user is far from the server.

　　CDN server:

　　The CDN server is a server network deployed all over the world. It aims to provide a faster and efficient content distribution by providing a more fast and efficient location by the location that is closer to users. The following are the characteristics of some CDN servers:

　　Content distribution: The CDN server can be replicated to multiple geographical servers, and the user can obtain the content from the closest server, thereby increasing the access speed.

　　Geographical distribution: The CDN server is distributed around the world, thereby reducing network delays, and users can load content faster.

　　Caches and acceleration: CDN server uses cache technology to store static content on the server to reduce the load of the source server and provide faster content transmission.

　　Load balancing: CDN uses load balancing and intelligent routing to improve the user's request route to the optimal server, thereby improving performance and reliability.

　　In short, ordinary servers are mainly used for custody websites, applications, and data, and the CDN server aims to provide more fast and efficient content transmission by distributing content on multiple geographical locations around the world. With the need to provide high -speed content distribution globally, using CDN can significantly improve the user experience.
