PHP??? I would have thought javascript or Ruby would have made more sense.It seems like Google is just reacting to requests from 4 years ago. The App Engine has mades some decisions that seem to be contradictory. At one end, they drastically increased their prices and sent a signal the GAE was an enterprise-focused platform. Now, they're releasing PHP so people can host blogs on it. Really? You want to compete with $…
It was the single most requested feature on the bug tracker by quite a bit. It's not something I want, but apparently there are quite a few people who do.
Also what people request and what google's vision is are two different things. Who are they targeting with this PHP stuff. Yes sure, for free-tier stuff, I'm sure lots of kids playing around with PHP would love to have a sand-box to play around. But this move seems inconsistent with their prior action that signaled a move toward enterprise sales.
Also, it feels like one side of google is not talking with the other side. They're building a whole application scripting system hosted on google Drive to work with google apps, etc. Why not provide the javascript on GAE to allow further application development and integration.
To be honest, this feels like: Oh shit! Google I/O is coming up and we need to have something to show than a vision of providing cloud-based computing solution that fits within their big vision.
