Google will address a large backlog of developers interested in its App Engine service by removing restrictions on the preview release starting late this morning.
More announcements are expected today and tomorrow at Google's first Google I/O developer conference in San Francisco. Google said over 2,900 developers have signed up for the event.
Launched in April as a free preview service, App Engine was initially only available to the first 10,000 developers to sign up. That limit was quickly reached and Google (NASDAQ:GOOG) let in an additional 65,000 developers via a waitlist.
"App Engine will always be free to get started, we think it's solving a big problem for developers," Google product manager Pete Koomen told InternetNews.com.
The free version available now gives developers up to 500 megabytes of storage and up to five million page views. Google plans to expand those limits on a paid basis later this year and today announced price ranges, which have yet to be finalized.
Additional storage will be available for between 15 to 18 cents per month, per gigabyte. Additional CPU processing will cost between 10 and 12 cents per CPU core-hour. Additional bandwidth will cost between 11 and 13 cents per GB (outgoing) and between 9 and 11 cents per GB (incoming).
The release comes at a time of growing interest in Software as a Service (SaaS) applications that are readily accessible via the Web. To further its appeal to enterprise users and mobile professionals, SaaS vendors, including Google, have started to offer offline access to some of its programs as well.
"We're pretty excited by the variety of applications we've seen built so far," said Koomen, noting there's been a range of both consumer and enterprise applications. While there are other hosting platforms for Web applications, such as Amazon's (NASDAQ:AMZN) Elastic Cloud Computing (EC2) and Simple Storage Service (S3), Koomen said Google has taken a different approach. "This is not a general computing platform," he said. "We're making it simple to build a Web application and scale."
He also said Google doesn't aspire to compete with large scale grid computing projects for things like biological research that can take hours of compute time. "App Engine is designed for lighter weight applications and processing on request."
