With the growing use of the archetypal LAMP, variations and retronyms appeared for other combinations of operating system, web server, database, and software language.
[7] The LAMP bundle can be combined with many other free and open-source software packages, including: As another example, the software which Wikipedia and other Wikimedia Foundation projects use for their underlying infrastructure is a customized LAMP stack with additions such as Linux Virtual Server (LVS) for load balancing and Ceph and Swift for distributed object storages.
