"AppScale is an open-source implementation of the Google AppEngine (GAE) cloud computing interface. AppScale enables execution of GAE applications on virtualized cluster systems. In particular, AppScale enables users to execute GAE applications using their own clusters with greater scalability and reliability than the GAE SDK provides. Moreover, AppScale executes automatically and transparently over cloud infrastructures such as the Amazon Web Services (AWS) Elastic Compute Cloud (EC2) and Eucalyptus, the open-source implementation of the AWS interfaces."

Open source google app engine implementation, supports Xen, extending to GAE, EC2

A BSD-licensed implementation of Google App Engine. Roll your own cloud computing platform.

In this post I thought I’d go through the steps you need to take to get a JRuby on Rails application working on GAE/J, and also what kind of characteristics you should expect from your application.

Write your Google App Engine applications in Groovy

Google just announced that their Google App Engine cloud hosting platform now supports other languages than Python: namely Java and Groovy!

ngine for Java makes it

exciting news!

Now RoR is supported by Google App Engine. What are you waiting for!?

"rails primer for google app engine"

Useful, quick and easy walkthrough of writing a Python/Django app which interfaces with Twitter, and deploying it to Google AppEngine.

Twitter’s robust REST API enables building of good applications that leverage its increasingly large and real-time data. Google’s cloud system App Engine not only provides a scalable platform for deploying applications, but also proves to be economically viable because of its pay per resource usage model and a large free quota. Little wonder then, there are increasingly large number of twitter apps being deployed on App Engine. In this post, I am going to examine how to create a simple application based on twitter’s REST API and deploy it on Google App Engine. A deployed version can be found on Twitter-Follow. The specification is simple. It finds if a twitter user is following another twitter user, given their user names. The application is developed using django and deployed on Appengine using the app engine patch project. The code is open sourced with GPL v3 and can be checked out from Google Code. Lets get started building this application.

Presentation on how googleapps datastore implements filtering and sorting on top of bigtable. Basically, all queries are translated to bigtable prefix scans or range scans, without needing any in-memory postprocessing, all rows returned from the scan are relevant to, and in order, for the query. There's a built-in 'single property index' (or two actually: one asc and one desc) which can obviously be used for single-property searches, but also for queries consisting of only equals clauses, by doing multiple range scans and taking the intersection (not sure at which level this happens). More complex queries need specific pre-defined indexes. Index tables only have keys, no columns with values. Indexes are updated synchronously, so everything stays consistent (at the cost of contention problems?). Some mention of string-byte considerations when doing range queries. No fulltext queries. Ends with some talk on transactions.

せっかくなのでJavaを使ってみたい、という人には、＠ITの記事をご紹介。Google App Engine/Javaの開発のためのJDKをGoogle App Engineにインストールし、手元のPCにはEclipseとプラグインのインストールから解説してくれます。後半ではBigtableデータの操作方法も。

they are blending the best of proper languages and markup languages. That there is no obfuscated code/bytecode (you ship Ruby to the "browser" app that will interpret it) is a good thing, it will dis

"I've spent some time over the last few weeks playing around with the Google App Engine so I figured it may be helpful to share some of the things that I have learned and do a tutorial series on how I built this simple blog using the GAE and Django."

helper

manual for defining web services to run - schedule tells when to run which URLs and how often to do it

Use Google app engine to run server-side web scripts regularly - as per suggestion in http://stackoverflow.com/questions/1955468/call-php-script-every-minute

gae2django is a Django helper application that provides an implementation of Google's App Engine API based on pure Django. The helper makes it easier to re-use applications originally designed for Google's App Engine environment in a Django environment. (If you want to run existing Django applications in Google's App Engine environment, then Google App Engine Helper for Django is the right choice for you...)
