Google App engine is a web hosting service from google. Can we call it a direct competition to Amazon’s s3 and Ec2 partially yes.

Google’s App engine runs your web applications on their cluster. It will become clearr why i said its only partial competition to Amazon’s services when we see the features of appengine and components in it.

What constitute Appengine?

• Language supported as of now: only Python
• Persistent storage using BigTable and GFS (Google filesystem)
• Automatic scaling and load balancing
• Google APIs for authenticating users and sending email
• Fully featured local development environment provided as sdk

What are its strengths?

• Google infrastructure

What are its weakness?

• No relational database (most application will have to be customized ).
• No access to filesystem (have datastore which can be used) but, again customization required.

What we get free?

• 500MB of persistent storage and
• enough CPU and bandwidth for about 5 million page views a month.
