Event Stream Processor supports SSL connections over the network to ensure the privacy of communication between client applications and ESP Server.
SSL is supported for remote procedure calls (XMLRPC) in the cluster. A node in the cluster supports either HTTP or HTTPS, but not both simultaneously. When SSL is enabled for a cluster, all components in the cluster are also enabled for SSL.
By default, SSL is enabled for Event Stream Processor. Users can install Event Stream Processor without SSL. If you have not configured a cluster during installation or want to create a new cluster, you can enable SSL in the cluster configuration file.
