The Amazon Appstore for Android is the place where developers can get exposure for their Android applications through automated merchandising and other marketing.  Amazon also offers great solutions for developers to build apps with the Amazon Web Services (AWS) Mobile SDK.

From September 7, 2011 through November 15, 2011, developers who submit an Android app to the Amazon Appstore are eligible to receive a one-time $50 promotion code for use on certain AWS services (subject to terms and conditions).  Promotion codes will be emailed directly to developers during the first week of October and the last week of November.

AWS delivers a set of simple building block services that together form a reliable, scalable, and inexpensive computing platform “in the cloud”. With AWS, developers can easily access a scalable and cost-effective cloud computing resources through simple API calls or with the use of the AWS Mobile SDK for Android (and iOS).  As noted in this blog post , some highlights of the AWS SDK for Android include:

• Storage – developers can store and retrieve any amount of data using Amazon S3
• Database – developers can add a highly available, scalable, and flexible non-relational data store using Amazon SimpleDB with little or no administrative burden
• Messaging – developers can integrate reliable, highly scalable mobile-to-mobile communication into applications using Amazon SQS and Amazon SNS

The SDK includes a library, full documentation, and some sample code.  You can get the library on GitHub.  Also, in true open source fashion, AWS is open to and encourages external contributions.
