Chapter 15 Introduction to Calendar Server Software

This chapter provides an overview of Sun Java System Calendar Server, the business reasoning behind deploying Calendar Server, and the deployment process itself.

This chapter contains the following sections:

Calendar Server Overview

Sun Java System Calendar Server is a high-performance, Internet standards-based calendar server designed with the scalability to meet the needs of customers ranging from medium- and large-sized enterprises to even the largest telecommunication and Internet service providers. Through a Web browser interface or connectors to other calendar clients, including Microsoft Outlook, Calendar Server provides group scheduling and personal calendaring to consumers at home or at work, while enabling them to share calendar information with others over the Internet.

Calendar Server provides one of the industry’s most open, interoperable, and high-performance time and resource management solutions. Through its scalability, performance, and reliability, it provides the features you require at a lower total cost of ownership than alternative solutions. Native support for iCalendar standards enables users to schedule events in a format that is easily shared across the Internet. Calendar Server employs standards and protocols such as:

The Calendar Server architecture is flexible, extensible, and scalable both vertically (by increasing the number of CPUs per system) and horizontally (by introducing additional servers into the network). As a result, Calendar Server can be thought of as a system of servers that can be configured to fit a variety of needs. It can remain in isolation as a standalone calendar server, or it can be configured with many instances, having the various services duplicated or split between them.

Calendar Server makes use of plugins to obtain external services. Calendar Server also supports both LDAP- and identity-based deployments, and integrates with Sun Java System Access Manager, Sun Java System Portal Server, and Sun Java System Instant Messaging to provide additional functionality.

Calendar Server provides the following benefits:

Designing Your Calendar Server Deployment

The deployment process consists of the following general phases, referred to as the Solution Life Cycle:

The deployment phases are not rigid: the deployment process is iterative in nature.

Objectives of Your Calendar Server Deployment

Before you begin your Calendar Server deployment planning, a good question to ask is:

Why is my organization deploying Calendar Server?

Several reasons to consider are:

Calendar Server Deployment Team

Deploying Calendar Server usually involves a number of people, each with different roles and responsibilities. In a small organization, one person might perform several roles. Some of the roles to consider are:

Calendar Server End Users

End users can connect to Calendar Server by using the Communications Express web client, or Sun Java System Connector for Microsoft Outlook.

Questions about end users at your site include:

Expected Calendar Server End User Performance

What are your specific performance requirements for your end users? For example:

What configuration do you plan to use for your deployment? Calendar Server configuration scenarios include:

If you plan to configure multiple front-end servers, how do you plan to distribute your end users?

If you plan to configure multiple back-end database servers, how do you plan to distribute your database? For example, you could distribute servers geographically.

What plans do you have for growth? For both front-end and back-end servers?
