Daniel Sabbah on LAMP: "I believe that in the same way that some of those simple solutions are good enough to start with, eventually, they are going to have to come up against scalability. [...] What we are trying to do is make sure businesses who start there [with LAMP] have a model, to not only start there but evolve into more complex situations in order to actually be able to grow." Brad Fitzpatrick and Mark Smith on LiveJournal: "College hobby project, Apr 1999. April 2004, 2.8 million accounts. April 2005, 6.8 million accounts. Thousands of hits/second." I think we're in good hands. Sabbah's argument is reminiscent of recent positioning of Web Services with respect to REST/Web systems - take the high-end and manage the disruption from below. Yes there are things to be done around scaling. But it's true to say we know what to do and that scaling issues are not unique to LAMP - when you get down it, it's still tiered client-server into a database, and IBM are not putting their substantial weight behind a toy architecture. The real question to ask about scalability is "scalability for what?" Unquantified ilities don't amount to a hill of beans in this crazy world....
