Google announced pricing plans for its App Engine service, which allows developers to run their web apps on Google's infrastructure, and was available in a free, but restricted version, until now. The free version currently gives developers up to 500MB of persistent storage and CPU power and bandwidth for about 5 million page views a month. The pricing for resources beyond those free quotas is:

• $0.10 per CPU core hour
• $0.10 per GB of incoming traffic and $0.12 per GB of outgoing traffic
• $0.15 per GB of data stored by the application per month
• $0.0001 per email recipient for emails sent by the application
