The only book to address using cache to enhance and speed up Web application development

• Developers use Apache, MySQL, memcached, and Perl to build dynamicWeb sites that store information within the MySQL database; this is theonly book to address using these technologies together to alleviate thedatabase load in Web development
• Covers each of the four systems and shows how to install, set up,and administer them; then shows the reader how to put the partstogether to start building applications
• Explains the benefits of a base perl library for code re-use, andprovides sample applications that demonstrate in a practical way theinformation covered in the previous chapters
• Examines monitoring, performance, and security, with aproblem-solving chapter that walks the reader through solvingreal-world issues

From the Back CoverAdding a cache layer to the popular LAMP stack is becoming thecommon solution to significantly reduce the load on back-end databases,and also allows for better web application performance. This newcaching component is represented by another “m” in LAMMP, which standsfor memcached—a high-performance, distributed memory object cachingsystem that provides caching for web applications. The author walks youthrough the process of using Perl to develop web applications both interms of the front-end display logic as well as the back-end dataretrieval from MySQL and memcached. You also see how to configure theApache web server to run these mod_perl applications.
You’ll discover that MySQL and memcached are where the data isstored, and Apache is the server that hosts this functionality. You’llalso examine each system while you learn how to install, set up, andadminister it.
The book shows you how to put each of these systems together so youcan start building successful applications. Helpful examples put inpractice the information covered throughout the book and aproblem-solving chapter offers real-world problems and the process ofhow you might go about finding a solution to them.
