Sun Java System Communications Services 6 2005Q4 Deployment Planning Guide

Communications Services Overview

Sun Java System Communications Services 6 2005Q4 are a secure, cost-effective communications and collaborations offering. Communications Services address customer concerns about costs, capabilities, and the security of the traditional communications infrastructure by offering a secure, scalable, lower total cost of ownership alternative to other communications and collaboration solutions.

Communications Services provide the email, calendar, and instant messaging solutions necessary to meet both enterprise and ISP communications and collaboration needs. The products and services that form Communications Services provide a compelling response to common business requirements. All organizations need communications, and many are required to provide these services across large, diverse, and geographically distributed communities of users. Traditional communications solutions are costly, and not sufficient to meet today’s requirements for scalability and security. Communications Services enable organizations to deploy solutions at a total cost of ownership they can afford.

In addition, Communications Services provide differentiated services and full-featured collaboration functionality that are required by a diverse audience. Finally, a Communications Services deployment meets your increased security needs when extending communications outside of a corporate firewall and to mobile users through multiple devices.

The Communications Services core solution consists of the following component products:

Additional features that enhance the Communications Services solution include:

Taken as a whole, Communications Services provide a standards-based, integrated communications and collaboration suite of products for enterprise deployments of many thousands of users, and ISP deployments of hundreds of thousands of users. Communications Services deliver a robust and flexible platform meeting the diverse communications needs of all types of organizations. Communications Services are an optimal solution to connect remote offices, distributed workgroups, and global corporate locations.

About Messaging Server

Sun Java System Messaging Server 6 is a high-performance, highly secure messaging platform. Scaling from thousands to millions of users, Messaging Server is suitable for businesses interested in consolidating email servers and reducing total cost of ownership of communications infrastructure. Messaging Server provides extensive security features that help ensure the integrity of communications through user authentication, session encryption, and the appropriate content filtering to help prevent spam and viruses.

With Messaging Server, organizations can provide secure, reliable messaging services for entire communities of employees, partners, and customers.

Messaging Server currently supports two client user interfaces (UI):

Going forward, no new features will be added to the Messenger Express user interface. It has been deprecated in favor of the Communications Express user interface. Sun Microsystems, Inc. will announce an end-of-life timeline for Messenger Express at a future date.

See Part II, Deploying Messaging Server for more information on Messaging Server concepts and other deployment aspects.

About Calendar Server

Sun Java System Calendar Server 6 facilitates team collaboration by enabling users to manage and coordinate appointments, events, tasks, and resources. With its intuitive, Web-based interface, Calendar Server enables end users to access their personal, public, or group calendars anytime, anywhere, from a Web browser. Deployments use Calendar Server, along with the Messaging Server and Instant Messaging, to offer users a comprehensive communications and collaborative environment.

About Instant Messaging

Sun Java System Instant Messaging 7 enables secure, real-time communication and collaboration. Instant Messaging combines presence awareness with instant messaging capabilities such as chat, conferences, alerts, news, polls, and file transfers to create a rich collaborative environment. These features enable one-to-one as well as group collaboration through either short-lived communications or persistent venues such as conference rooms or news channels. Instant Messaging, along with Calendar Server and Messaging Server, offers users a comprehensive communications and collaboration environment.

Instant Messaging ensures the integrity of communications through its multiple authentication mechanisms and secure SSL connections. Integration with Sun JavaTM System Portal Server 6 and Sun JavaTM System Access Manager 6 brings additional security features, services-based provisioning access policy, user management, and secure remote access. Furthermore, Instant Messaging supports the Extensible Messaging and Presence Protocol (XMPP). XMPP enables you to use a number of third-party clients, which aggregate contacts from the public networks. In one client, you can have contacts from AIM, Yahoo, MSN, Sun, and other XMPP-based servers.

See Part IV, Deploying Instant Messaging for more information on Instant Messaging concepts and deployment aspects.

About Communications Express

Sun Java System Communications Express 6 provides an integrated web-based communications and collaboration client. Communications Express is a common part of Messaging Server and Calendar Server, providing end users with a web interface to their calendar information and mail, as well as an address book.

See Part V, Deploying Communications Express for more information on Communications Express concepts and deployment aspects.

About Synchronization

Sun ONE Synchronization 1.1 is a software product that runs on a Windows personal computer and enables users to synchronize Calendar Server events and tasks with mobile devices and personal information managers (PIMs) such as Microsoft Outlook.

See the Sun ONE Synchronization documentation at the following location for more information:

About Connector for Microsoft Outlook

Sun Java System Connector for Microsoft Outlook 7 enables Outlook to be used as a desktop client with Messaging Server and Calendar Server.

Connector for Microsoft Outlook is an Outlook plug-in that you install on end-users’ desktops. Connector for Microsoft Outlook queries Messaging Server for folder hierarchies and email messages. Connector for Microsoft Outlook then converts the information into Messaging API (MAPI) properties that Outlook can display. Similarly, Connector for Microsoft Outlook queries Calendar Server for events and tasks, which are then converted into MAPI properties. With this model, Connector for Microsoft Outlook builds an end-user Outlook view from two separate information sources: mail from Messaging Server and calendar information from Calendar Server.

Similarly, Connector for Microsoft Outlook uses Web Address Book Protocol (WABP) to query Address Book Server for contacts, which are then converted into MAPI properties. With this model, Connector for Microsoft Outlook builds an end-user Outlook view from three separate information sources: mail from Messaging Server, calendar information from Calendar Server, and contacts from Address Book Server.

See the Connector for Microsoft Outlook documentation at the following location for more information:

Communications Services Component Product Dependencies

Communications Services have dependencies on other Sun Java System component products that provide infrastructure services. These component products include Sun JavaTM System Directory Server and, optionally, Sun Java System Access Manager. Additionally, Communication Services depend on a web server to serve HTML content and provide HTML connections. You can use Sun JavaTM System Web Server (formerly SunTM ONE Web Server) or Sun JavaTM Application Server to fulfill this need.

Communications Services also depend on the existence of DNS. You need to have a functioning DNS server before you can install the Communications Services products.

See Chapter 3, Understanding Product Requirements and Considerations for more information on product dependencies.
