Communicating with employees who are not in-house, with customers at distant locations and to multiple internal employees can be a challenge with some communications systems. Some enterprises are finding that their current communications systems are not cost effective, don't scale according to their needs, are difficult to integrate with a new collaboration service or increase the security concerns of communicating with external employees and customers.

The Sun Enterprise Messaging Reference Architecture provides the email, calendar and instant messaging infrastructures necessary to meet enterprise communications needs. It is designed to be secure, reliable and horizontally scalable. This reference architecture offers an alternative to enterprises that want to lower their total cost of ownership while increasing their uptime and security.

The hardware components of the Reference Architecture are:

• Sun FireTM V60x servers and Sun FireTM V65x servers
• Sun StorEdgeTM 3310 SCSI array

The software components are:

• Sun JavaTM System Messaging Server 6.1
• Sun JavaTM System Calendar Server 6.0
• Sun JavaTM System Instant Messaging 6.1
• Sun JavaTM System Directory Server 5.2
• Sun JavaTM System Identity Server 6.1
• SolarisTM 9 Operating System (Solaris OS) (Hardened)

This Reference Architecture provides the implementation details that enable enterprises with employees distributed across the world to communicate and collaborate securely from any device. It is designed to integrate into existing environments and to save money. According to Dr. Sara Radicati, President and CEO, The Radicati Group, "For an organization with 10,000 users, the current annual cost of providing messaging and collaboration tools can typically be around $3 million to $4 million per annum. The cost disparity between running a Microsoft based system and some other options can be very large -- with systems based on Sun Java System Communications software offering a per user Total Cost of Ownership that can be less than half that of a Microsoft based system."
