What is the difference between TLS and SSL and how do I use it?

Since there is no use of experience, here are a few questions that you would like experienced brothers to share under the experience of using:

• For developers, using TLS and SSL is just a different configuration? Does OpenSSL implement both protocols at the same time?
• Using TLS or SSL, is it not all HTTPS when accessing the call?
• How big is the difference in time between using and not using HTTPS?
• If you do the configuration on the proxy server and you hang N tomcat behind, will the bottleneck appear on the proxy server? What if I configure it separately on Tomcat?

TLSis SSL the new name, SSL the version number from 1.0 to 3.0, TLS 1.0 = SSL 3.1 .
OpenSSL implements the ssl1.0~3.0 and TLS1.0 protocols.
HTTP over SSL/TLS is HTTPS
Unless you are a large file download site, the performance of using HTTP and HTTPS is very different
In general, Tomcat is very slow, if the proxy server using Nginx or apache,1 drag 10 when the bottleneck generally does not appear on the proxy server, but more difficult to say.
