Let’s Encrypt is a free and open Certificate Authority, that simplifies and automates processes of browser-trusted SSL certificates issuing and appliance. This is achieved through obtaining a browser-trusted SSL certificate from Let's Encrypt and attaching it to environment entry point (i.e. either compute node or load balancer). Upon integrating such certificate into your application, it will start supporting secure connection via the HTTPS protocol.Herewith, pay attention that Tomcat 8/9, GlassFish 4 and HAProxy servers are supported only starting with 4.9.5 Jelastic Platform version. Other stacks support is going to be implemented further.
