Externally access Agile Web Application
If I understand your question correctly, you are planning to implement https for external users, e.g. supplier users.
Without knowing the architecture it is a bit hard to give you a good answer.
Everything starts with a properly signed ssl key pair to be deployed on the load balancer or web server.
A challenge is that it is not possible to define different URLs for external and internal users. In most cases you will have to consider https for internal users as well. This in turn might require the roll-out of an ssl certificate to all JVMs that act as a client.
SSL can be a bit tricky topic, but there are good TNs on Oracle Support.
You need to purchase SSL certificates and implement Web proxy concept . As you said its linux you should go with Apache server.
You will find some information in Oracle documentation:
