Adding a cache layer to the popular LAMP stack is becoming thecommon solution to significantly reduce the load on back-enddatabases, 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, distributedmemory object caching system that provides caching for webapplications. The author walks you through the process of usingPerl to develop web applications both in terms of the front-enddisplay logic as well as the back-end data retrieval from MySQL andmemcached. You also see how to configure the Apache web server torun 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'll also examine each system while you learn how to install, setup, and administer it.
The book shows you how to put each of these systems together soyou can start building successful applications. Helpful examplesput in practice the information covered throughout the book and aproblem-solving chapter offers real-world problems and the processof how you might go about finding a solution to them.
