All you need is web

Google Apps Engine

Google Apps Engine is one of the service from Google and it can develop web application using Java or Python and execute it on Google’s infrastructure and able to maintain versions.

Google Apps Engine can only use API which supports Python or Java so right now there are only few of the functions available.

• Big Table
• HTTP requests
• e-mail
• pictures
• caching
• cron
• XMPP communication

O ther service allows to do more than this.

In my opinion, I would think both got good strength but it might be better learning ruby on rails instead of google apps engine for being able to work in broad view.

Side Note…

Reasons why Google Apps Engine is chosen…

Easy to get Started
App Engine is a complete development stack that uses familiar technologies to build and host web applications. With App Engine you write your application code, test it on your local machine and upload it to Google with a simple click of a button or command line script. Once your application is uploaded to Google we host and scale your application for you. You no longer need to worry about system administration, bringing up new instances of your application, sharding your database or buying machines. We take care of all the maintenance so you can focus on features for your users.

Automatic scalability
For the the first time your applications can take advantage of the same scalable technologies that Google applications are built on, things like BigTable and GFS. Automatic scaling is built in with App Engine, all you have to do is write your application code and we’ll do the rest. No matter how many users you have or how much data your application stores, App Engine can scale to meet your needs.

The reliability, performance and security of Google’s infrastructure
Google has a reputation for highly reliable, high performance infrastructure. With App Engine you can take advantage of the 10 years of knowledge Google has in running massively scalable, performance driven systems. The same security, privacy and data protection policies we have for Google’s applications applies to all App Engine applications. We take security very seriously and have measures in place to protect your code and application data.

Cost efficient hosting
App Engine will always be free to get started, and you can purchase more computing resources, paying only for what you actually use. Detailed pricing for usage that has exceeded the free quota of 500 MB of storage and around 5M pageviews per month.

Risk free trial period
Not only is creating an App Engine application easy, it’s free! You can create an account and publish an application that people can use right away at no charge, and with no obligation. An efficient application on a free account can use up to 500MB of storage and up to 5 million page views a month. When you are ready for more, you can enable billing, set a maximum daily budget, and allocate your budget for each resource according to your needs.
