2011 has seen some exciting releases for App Engine. As the days get shorter, the weather gets colder, and all that Halloween candy starts tempting everyone in the grocery store, we’ve been hard at work on our latest action-packed release.

Premier Accounts

When choosing a platform for your most critical business applications, we recognize that uptime guarantees, easy management and paid support are often just as important as product features. So today we’re launching Google App Engine premier accounts.  For $500 per month (not including the cost to provision internet services), you’ll receive:
  • Premium support (see the 
  • Technical Support Services Guidelines for details).
  • A 99.95% uptime Service Level Agreement (see the draft agreement; the final agreement will be in the signed offline agreement).
  • The ability to create an unlimited number of apps on your premier account domain.
  • No minimum monthly fees per app. Pay only for the resources you use.
  • Monthly billing via invoice.
To sign up for a premier account, please contact our sales team at appengine_premier_requests@google.com.  

Python 2.7

PIL? NumPy? Concurrent requests? Python 2.7 has it all, and today we’re opening up Python 2.7 as an experimental release. We’ve put together a list of all the known differences between the current 2.5 runtime and the new runtime.

Overall Changes

We know that bumping up against hard limits can be frustrating, and we’ve talked all year about our continued push to lift our system limits. With this release we are raising several of these:
  • Request Duration: The frontend request deadline has been increased from 30 seconds to 60 seconds. We’ve increased the maximum URLFetch deadline to match from 10 seconds to 60 seconds.
  • File limits: We’ve increased the number of files you can upload with your application from 3,000 to 10,000 files, and the file size limit has also been increased from 10MB to 32MB.
  • API Limits: Post payloads for URLFetches are now capped at 5MB instead of 1MB.
We’re also announcing several limited preview features and trusted tester programs:
  • Cloud SQL Preview: We announced last week that we are offering a preview of SQL support in App Engine. Give it a try and let us know what you think.
  • Full-text Search: We are looking for early trusted testers for our long-anticipated Full-Text Search API. Please fill out this form if you’re interested in trying it out.
  • Conversion API: Ever wanted to convert from text to PDF in your App? Then consider signing up as a trusted tester for the Conversion API.
Datastore
  • Cross Group (XG) Transactions: For those who need transactional writes to entities in multiple entity groups (and that's everyone, right?), XG Transactions are just the thing. This feature uses two phase commit to make cross group writes atomic just like single group writes.
Platform Improvements
Of course, these are just the high level changes. This release is packed full of features and bug fixes, and as always, we welcome your feedback in the group.

Since the general availability launch of the Prediction API this year at Google I/O, we have been working hard to give every developer access to machine learning in the cloud to build smarter apps. We’ve also been working on adding new features, accuracy improvements, and feedback capability to the API. Today we take another step by announcing Prediction v1.4. With the launch of this version, Prediction is graduating from Google Code Labs, reflecting Google’s commitment to the API’s development and stability. Version 1.4 also includes two new features:
  • Data Anomaly Analysis
    • One of the hardest parts of building an accurate predictive model is gathering and curating a high quality data set. With Prediction v1.4, we are providing a feature to help you identify problems with your data that we notice during the training process. This feedback makes it easier to build accurate predictive models with proper data.
  • PMML Import
    • PMML has become the de facto industry standard for transmitting predictive models and model data between systems. As of v1.4, the Google Prediction API can programmatically accept your PMML for data transformations and preprocessing.
    • The PMML spec is vast and covers many, many features. You can find more details about the specific features that the Google Prediction API supports here.



We’re looking forward to seeing what you create with these new capabilities!

Feel free to find us and ask questions about these new features on our discussion group or submit feedback via our feedback form.

Google Storage for Developers is now out of Code Labs, and has a new name: Google Cloud Storage. In addition, we're also happy to announce some new features, and a significant price reduction.

App Engine File API Support

When we opened the service to all this summer, many of our customers asked for an easier way to use Google Cloud Storage with their App Engine applications. In response to your feedback, you can now read and write your data via the App Engine Files API, enabling you to quickly build your content management tools, data sharing applications, web games and more using the powerful combination of App Engine and Cloud Storage. This feature is experimental and currently Python-only, but we’re working on adding Java support and additional features.

Usage Information

We’re introducing a new API that gives you access to detailed usage information (including network access and storage use data). You can use this feature to analyze your usage, integrate with your analysis systems and build your own value-added applications using Google Cloud Storage. This feature is currently experimental.

Lower Prices

We're no longer charging for upload bandwidth into the Google cloud. In addition, we’re lowering our prices across the board and introducing volume discounts for our larger users. We are committed to offering an extremely high quality of service to all our customers. As the product has evolved, we’ve found ways to offer the same great service at a lower cost, so now our prices are lower too. For example, under our new prices, a customer storing a hundred terabytes of data, reading twenty terabytes and writing ten terabytes a month would pay approximately 40% less a month. The difference is even greater for customers with higher usage. Our new prices are retroactive to the beginning of October. Please see our updated pricing here.

As always, we welcome your feedback in our discussion group. If you haven’t yet tried Google Cloud Storage, you can sign up and get started here.
