RE: Cloud Service comparison: Google App Engine vs. Joyent

The biggest reason I see that Joyent is a leader in facebook app hosting is becaue Joyent offers a true virtual machine set up preconfigured to run PHP, Rails, and Python. You can get root access and run shell scripts. It’s setup to scale out based on demand. (Question to self: I wonder how they scale the database part). Another huge plus is that Joyent is peered with Facebook’s network…thus eliminating any bandwidth costs. Also, the first year is free.

Google’s app engine on the other hand is a container for python/django apps. No shell access. But they handle all the scaling issues. Also, you might run out of bandwidth pretty quickly if it’s a successful app and google app engine is only in preview mode with limited bandwidth available.

Subject: Cloud Service comparison: Google App Engine vs. Joyent

According to the "Cloud Computing" entry in Wikipedia, it states that "Currently 25% of Facebook daily active application usage runs on Joyent."

Can anyone provide reasons why Facebook uses Joyent instead of, say, Google App Engine?

Also, in more general terms, can anyone provide examples where Joyent would be better than Google App Engine, or vice-versa?

Superficially, it appears the main difference, from a developers point of view, is that Joyent offers wider language support than Google's App Engine (python only).

Thank you very much,
