Is it necessary to install the ssl certificate on the server?

Some webmasters said that the SSL certificate can be installed on the server, and some webmasters said that they only need to set it in the CDN instead of installing it on the server. Is it necessary to install the SSL certificate on the server?

    Normally, the SSL certificate is installed on the server. If a CDN is used, the SSL certificate will also be configured in the CDN. This is the most secure method. In this way, the data will be encrypted between the CDN and the server, and between the CDN and the user. The data will be more secure and reliable.

    Of course, some webmasters are lazy. Instead of installing an SSL certificate on the server, they directly configure an SSL certificate in the CDN, so that the transmission between the CDN and the server is not encrypted, but only between the CDN and the user. Although this practice saves some things, it does have security vulnerabilities, and I do not recommend it.
