I'd argue it succeeded because it didn't require you to run a server. All those cpanel lamp ISPs mean sign in and upload code. All other solutions, java, .net, node, python, Haskell, etc require you to run and maintain your own servers. A minor exception for CGI based solutions but those were all too heavy.
