About Components

Zend Server is comprised of several components that each contributes important functionality to facilitate the development process.

The components are:

• Zend Debugger - The Zend Debugger communicates with the Zend (PHP) Engine to retrieve runtime information and present it in Zend Studio for root cause analysis.
• Zend Optimizer+ - The Zend Optimizer+ component speeds up PHP execution via opcode caching and optimization.
• Zend Guard Loader - The Zend Guard Loader is used in order to run PHP scripts that are encoded with Zend Guard.
• Zend Data Cache - The Zend Data Cache component provides a set of PHP functions to improve performance, by storing data in the cache.
• Zend Java Bridge- The Zend Java Bridge component makes it possible to use Java classes and code from within PHP.
• Zend Framework - An open source framework for developing Web applications and Web services with PHP.

• Zend Monitor - The Zend Monitor component is integrated into the runtime environment and serves as an alerting and collection mechanism for early detection of PHP script problems.

• Zend Page Cache - The Zend Page Cache component is used to cache the entire output of PHP scripts, without changing the PHP code.

• ZDS (Zend Download Server) - The ZDS (Zend Download Server) component improves Apache's scalability by managing static content downloads and passing them to a dedicated process optimized for parallel downloads (not supported in Microsoft Windows).

• Zend Job Queue - The Jobs Jobs contain information about a specific Job (script to run) that you have set to run in your environment. Component is used to streamline offline processing of PHP scripts.

• Zend Code Tracing - Code Tracing enables real-time execution flow recording in Production Environments.

• Zend Session Clustering - Scales environments to a cluster.

For a short description of each component and where it is installed, see the Installed Components section in the Installation Guide.

Comprehensive caching takes the improved application responsiveness offered by Zend Server and expands it to an entire cluster – those optimizations include accelerating PHP execution, caching page content, and optimizing file and content downloads to improve the overall user experience
