Adding a cache layer to the popular LAMP stack is becoming the common solution to significantly reduce the load on back-end databases, and also allows for better web application performance. This new caching component is represented by another "m" in LAMMP, which stands for memcached—a high-performance, distributed memory object caching system that provides caching for web applications. The author walks you through the process of using Perl to develop web applications both in terms of the front-end display logic as well as the back-end data retrieval from MySQL and memcached. You also see how to configure the Apache web server to run these mod_perl applications.
You'll discover that MySQL and memcached are where the data is stored, and Apache is the server that hosts this functionality. You'll also examine each system while you learn how to install, set up, and administer it.
The book shows you how to put each of these systems together so you can start building successful applications. Helpful examples put in practice the information covered throughout the book and a problem-solving chapter offers real-world problems and the process of how you might go about finding a solution to them.
