It has enabled us to build an API that feels and behaves like APIs from YouTube, Google Maps and other Google services...We would never have been able to offer something comparable in the same amount of time. Building all of that without Google Cloud Endpoints would have been unthinkableServer Side Annotation LanguageJavaPythonpackage guestbook;

Mobile Backend Starter UpdateMobile Backend StarterGoogle Cloud Messaging

Handling Large Media Files: Many mobile applications let users view and upload videos and high resolution images. But storing and serving this content can be cumbersome. Google Cloud Storage offers high durability and availability at low cost. MBS now allows you to easily manage user-isolated and secure access to data in Cloud Storage directly from your iOS or Android application, with no server coding required.

Imagine that you are building an expense reporting mobile app and you want to allow your users to upload pictures of their receipts. This is very straightforward. Your Android or iOS app can obtain a secure upload URL that only your application can use and then use standard client libraries to stream bytes to Google Cloud Storage. In this snippet of code for Android notice that in this case the uploaded file will be available only to the user who uploaded it.

// get a secure URL for uploading a private file
URL url = blobEndpoint.getUploadUrl("receipts",  
                             getReceiptFileName(),"PRIVATE")
                       .execute().getShortLivedUrl());

Downloading images and other files is also easy. You start with obtaining a secure download URL and then you can use standard client libraries to download bytes from Google Cloud Storage. MBS will authenticate the caller and check if it is allowed to download the file.

// get a secure URL for downloading a file
URL url = blobEndpoint.getDownloadUrl("receipts", 
                             getReceiptFileName())
                       .execute().getShortLivedUrl());

Updated Mobile Clients: We have updated the template mobile clients as well. Both Android and iOS display an updated user interface and incorporate best practices. The Android client sports the newest version of Google Cloud Messaging.

Just Develop IT Migrates Petabytes of Data to Google Cloud Storage

Thursday, November 7, 2013

We interviewed Brooke Bryan, CTO of Just Develop It Ltd (JDI), one of the leaders in device data backup with popular applications including My PC Backup. In early 2013, the company migrated 5 petabytes of data from Amazon S3 to Google Cloud Storage. Since then, JDI’s business has expanded their use to over 10 petabytes at a rate of 800 terabytes a month.What does Just Develop IT do?Skylark Golf & Country ClubJust CloudWhy did JDI want to migrate to the cloud? Why did you switch from Amazon S3 to Google Cloud Storage?Google Cloud StorageWhat challenges did the migration present?

We needed high network bandwidth and parallel data transfer mechanisms to ensure that the migration could be completed as soon as possible.

Since JDI has multiple storage/backup products, the process had to be invisible to our users, as a disruption of service would directly affect the confidence in our products.

We had to keep costs low during the process, which raised two issues: We paid twice the fees to store objects in both Amazon and Google systems in order to ensure that services would not be disrupted; and if an object was copied multiple times, we incurred unnecessary AWS egress network costs.

How did Google meet these challenges? Google Compute EngineHow has your experience with Google been since the implementation?

Kaplan builds online education platform KAPx with Google App Engine

Friday, November 1, 2013

Today's guest post is from Charlie Ward, VP of Platform Development at Kaplan Inc., a global educational services company that operates in 170 countries and serves one million students annually. Charlie describes why Kaplan chose Google App Engine as the foundation for a scalable, flexible, and robust education platform that allows anyone to easily deliver learning content in both live and recorded formats.The Drivers for ChangeFirst impressions with Google App Engine

Adding on Google Hangouts & Google AppsKAPxKaplan UniversityMount Washington CollegeTips for getting started with Google App Engine

There are many excellent examples of App Engine solutions in the GoogleCloudPlatform repository on GitHub to get you started.

Use webapp2 and the jinja2 template engine for serving up content unless you need something heavier. This lightweight but flexible combination is simple to use and provides an easy way to deliver MVC style HTML templates as well as raw data for RESTful APIs.

Use the NDB datastore libraries to get memcache for free. NDB was experimental when we first launched our platform, so we went with GAE’s DB datastore having to write our own handlers for front loading DB queries with memcache. With NDB, this is provided for you, dramatically improving performance and shortening development time.

Plan ahead if you are going to need to aggregate data (join, counts, etc). Operations that you would typically rely on in a relational database (joins, groupings and aggregate functions) are not as straightforward when working with the NoSQL DB or NDB datastore. You’ll want to plan out your models with the appropriate keys / properties to support aggregation in code foregoing joins and grouping when possible.

When relying heavily on the built in datastore and memcache implementations, you’ll want to understand their upper limits and design around them. There are excellent articles available on eventual consistency, sharding data, reducing datastore contention, async task queues, and MapReduce in the developers.google.com/appengine site that can provide you with techniques to work within the boundries of service quotas and the constraints of a highly scalable environment.

Invest time upfront to set up automated extracts of your log data to Google BigQuery on a regular basis. This will pay huge dividends the first time you need to track down a bug in production, as the dashboard tools out of the box are cumbersome to work with at scale.

Use the --datastore_consistency_policy=random option on dev_appserver.py when developing locally to identify potential problems with delayed datastore writes before deploying.
