Amazon recently announced developer components (SDKs) to make it easy to use cloud services on mobile devices. This move demonstrates how significant Amazon views the mobile market.
From the Amazon Web Services Blog:
We want to make it easier for developers to build AWS applications on mobile devices. Today we are introducing new SDKs for AWS Development on devices that run the Google’s Android and Apple’s iOS operating systems (iPhones, iPads, and the iPod Touch).
The AWS SDK for Android and the AWS SDK for iOS provide developers with access to storage (Amazon S3), database (Amazon SimpleDB), and messaging facilities (Amazon SQS and Amazon SNS). Both SDKs are lean and mean to allow you to make the most of the limited memory found on a mobile device. The libraries take care of a number of low-level concerns such as authentication, retrying of requests, and error handling.
In the future, we expect that every cloud provider will target mobile developers. With the increased efficiency from cloud hosting, it becomes easier for mobile apps to scale to handle millions of users.
