Vertical scaling and required SSL implementation

In a vertical scaling and required SSL implementation you maximize the number of client connections supported on a single host and provided SSL-encrypted security between client and server communications.

The key features of this implementation are:

• The HPE Service Manager system consists of several servlet container processes running on one physical host
• The implementation allows administrators to specify a system connection limit
• The HPE Service Manager system can manage a number of concurrent client connections up to the number of servlet container processes times the threadsperprocess value (For example, 6 servlet container processes supporting 50 threadsperprocess can support up to 300 client connections)
• The implementation allows administrators to specify the communication ports the system uses
• The implementation requires SSL-encrypted communications between HPE Service Manager clients and servers
• A dedicated load balancer process manages and routes client connections to available servlet container processes
• Administrators can dynamically add and remove HPE Service Manager instances from a virtual group

A vertical scaling implementation is typically used in small to medium environments where hardware system resources are limited. A vertical scaling implementation can support as many client connections as the HPE Service Manager host has available system resources.

You can convert a vertical scaling implementation into a horizontal scaling implementations with the addition of virtual grouping parameters and one or more additional servlet container instances installed on separate physical hosts.
