During the Android portion of the Google I/O keynote, we showed Cross-Platform Single Sign-On; the effect was that for Wallet and Google+ users, signing in to a Web browser resulted in automatic download of, and sign-in to, an Android app.

To support this, we have introduced general-purpose API tools which allow developers to achieve cross-client authentication and authorization, in particular between Android and Web apps.

Not having to sign in repeatedly feels so natural for users that they don’t even notice it. But as more and more apps deploy this sort of magic, you don’t want to be the hold-out that’s pestering users for passwords on Web sites or, worse, on tiny mobile-device keyboards.

On the Android side, client libraries like PlusClient, GamesClient, and WalletClient have “connect” methods that take care of this as automatically as possible; they check whether any of the accounts on the phone have already been authorized for access to the service in question, conduct sign-in if necessary but avoid it if possible, and when they return to your code, everything’s all set up.

If you’re writing server-side code and using libraries like Google+ Sign-In, once again, all the right things happen automatically; when you start accessing the service, the software imposes the minimum necessary pain on the user, ideally zero, and lets you get to work.

Of course, some people want less automation, and finer control over how things work. If you want to access our services at the HTTP level rather than via a library, or to deal with multiple accounts on an Android device in a customized way, you can do these things and in most cases still deliver the no-sign-in magic.

Of course, this involves working with HTTP message flows, validating tokens, and securing shared secrets. This may sound intimidating but will be straightforward for one well-versed in HTTP-level Web programming. If you’re one of those, check out the low-level protocols and APIs that support this, in “Cross-Client Identity”.

The time is now to start moving your apps towards a sign-in-free future.

Watch the video of the Cloud track kickoff.

Over the last fourteen years we have been developing some of the best infrastructure in the world to power Google’s global-scale services. With Google Cloud Platform, our goal is to open that infrastructure and make it available to any business or developer anywhere. Today, we are introducing improvements to the platform and making Google Compute Engine available for anyone to use.

Google Compute Engine - now available for everyone

Google Compute Engine provides a fast, consistently high-performance environment for running virtual machines. Later today, you’ll be able to go online to cloud.google.com and start using Compute Engine.

In addition, we’re introducing new Compute Engine features:

• Sub-hour billing charges for instances in one-minute increments with a ten-minute minimum, so you don’t pay for compute minutes that you don’t use
• Shared-core instances provide smaller instance shapes for low-intensity workloads
• Advanced Routing features help you create gateways and VPN servers, and enable you to build applications that span your local network and Google’s cloud
• Large persistent disks support up to 10 terabytes per volume, which translates to 10X the industry standard

We’ve also completed ISO 27001:2005 international security certification for Compute Engine, Google App Engine, and Google Cloud Storage.

Google App Engine adds the PHP runtime

App Engine 1.8.0 is now available and includes a Limited Preview of the PHP runtime - your top requested feature. We’re bringing one of the most popular web programming languages to App Engine so that you can run open source apps like WordPress. It also offers deep integration with other parts of Cloud Platform including Google Cloud SQL and Cloud Storage.

We’ve also heard that we need to make building modularized applications on App Engine easier. We are introducing the ability to partition apps into components with separate scaling, deployments, versioning and performance settings.

Introducing Google Cloud Datastore

Google Cloud Datastore is a fully managed and schemaless solution for storing non-relational data. Based on the popular App Engine High Replication Datastore, Cloud Datastore is a standalone service that features automatic scalability and high availability while still providing powerful capabilities such as ACID transactions, SQL-like queries, indexes and more.

Over the last year we have continued our focus on feature enhancement and developer experience across App Engine, Compute Engine, Google BigQuery, Cloud Storage and Cloud SQL. We also introduced Google Cloud Endpoints and Google Cloud Console.

With these improvements, we have seen increased usage with over 3 million applications and over 300,000 unique developers using Cloud Platform in a given month. Our developers inspire us everyday, and we can’t wait to see what you build next.
