Highlights from our Google I/O Presentations

Now that things have settled down from last month’s Google I/O, we thought it would be a good time to highlight some of the technical talks given by the App Engine team. At this year’s I/O, we emphasized some of the big themes we’ve been focusing on this past year: availability and productionization of our platform, removing limits while maintaining performance at scale, and developing new APIs.


Availability and Productionization of our Platform


Since App Engine automatically handles all of the sharding and distribution of your application across datacenters, we thought it would be important to talk about the strategies we use to run and maintain our platform. These talks also give you an opportunity to meet some of the engineers who carry pagers so you don’t have to.



  • More 9s Please: Under the Covers of the High Replication Datastore - We were excited to announce the HR Datastore in January, since it provides a high level of availability, even during unplanned outages, and even if an entire datacenter goes offline. HRD uses the paxos algorithm to distribute data across multiple datacenters. Alfred Fuller and Matt Wilder talk about the high level distribution strategy used and how this helps keep your app serving.

  • Life in App Engine Production - Let’s face it - everyone has some great war stories about running live applications. And the stories of Google’s SRE team probably rank with the best of them. Michael Handler and Alan Green talk about what goes right and what can go wrong running in Production.


Removing Limits while maintaining performance at scale


How can you design your application so you can transition from serving 1 user to 1 million users with the minimum amount of work? How do you make sure your user experience stays consistent for those users?



  • App Engine Backends - At I/O this year we launched App Engine Backends, which allow you to write long running processes on App Engine. Crunch numbers, process data, and build large in-memory models! Justin Haugh and Greg Darke give an overview of this new feature and cover best practices.

  • Scaling App Engine Applications - We always get lots of question on what it means and how it works to scale an app using App Engine (hint: low latency is the key!). Guido van Rossum and Justin Haugh explain how instances work and cover best practices for scaling your application.



Developing New APIs



  • Full Text Search - It took 8 days after App Engine’s initial launch for this feature request to be filed - and now work on the Full Text Search API is nearing completion. Bo Majewski and Ged Ellis give a preview of the upcoming App Engine Full Text Search API.

  • App Engine MapReduce- So you just want to analyze 5TB of data? You’ll probably need MapReduce to do so! Mike Aizatsky talks about the progress being made on the App Engine MapReduce framework and how you can use it to generate reports for your data.

  • Large-scale Data Analysis using the App Engine Pipeline API - Once you’ve written one MapReduce, you’ll probably want to write more, and then you’ll need a way to manage your application’s analysis pipeline. In this talk, Brett Slatkin discusses a lightweight API for managing MapReduce workflows.


Our team always enjoys participating in Google I/O because our engineers get to share their vision and discuss their work with a large audience. If you are interested in what some of our customers had to say at I/O, check out the Google Enterprise Blog. Of course, with App Engine featured in 23 talks for Google I/O, we couldn’t cover them all here. See the complete session list for I/O and discover all the talks on App Engine and more!



Google Goggles learns Russian and gets a new view

Some of you may already be using the new optical character recognition (OCR) and translation of Russian in Google Goggles that we previewed at last week’s Inside Search event. Starting today, we’re pleased to introduce some additional new features, including a map view of your Search History and the ability to copy contact and text results to the clipboard. We’ve also changed the results interface to make it easier to view and navigate through your results.

Russian optical character recognition (OCR) and translation
Since Google Goggles first launched in 2009, it has been able to recognize and translate text in a number of different languages, as long as the language used Latin characters. With the launch of OCR for Russian, Goggles is now able to read Cyrillic characters. Goggles will recognize a picture of Russian text and allow you to translate the text into one of over 40 other languages. Russian OCR is also available for users of Google Goggles on the Google Search app for iOS. Очень полезно!

You can take a picture of Russian text and translate it into over 40 languages.


Map view of your search history
If you’ve enabled search history on Goggles, your history contains a list of all the images that you’ve searched for, as well as some information about where you performed the search if you chose to share your location with Google. Sometimes this can be a pretty long list, so we wanted to give you another way to sort and visualize your Goggles results.

We’ve added a map view, which shows your Goggles image search history on a map so you can quickly zoom and pan to find a query from a particular location.

Easily toggle between map view and list view with the button in the upper right.


Copy contact and text results to clipboard
Finally, imagine that you wanted to grab a URL or telephone number from a sign and email it to yourself. Now, Goggles gives you the option of copying the recognized text to your phone’s clipboard, allowing you to paste the test into a number of applications.

To try these new features download Google Goggles 1.5 from Android Market, or scan the QR code below with your phone.
