Wow, Amazon is a clouding service provider. Let's call it as AWS.

Amazon Web Services (AWS) is one of the IaaS (Infrastructure as a Service) in clouding service. AWS offers a complete set of infrastructure and application services that enable you to run virtually everything in the cloud from enterprise applications and big data projects to social games and mobile apps. Amazon began the service with the idea of utilizing stand-by IT assets during off-season.

Amazon EC2

Amazon EC2 is the most typical IaaS service component of Amazon. Amazon virtualized hardware servers and provides the user with virtualized hardware resources, and the user installs OS and soft wares on the virtual machine. The user selects pre-configured OS image and software or just uploads his or her own image in the form of Amazon AMI (Amazon Machine Image) for use. EC2 takes the advantage of being able to install the desired OS and most of the software so as to have high capacity platform for hardware virtualization by default.

Amazon SDB (Simple DB)

Simple DB is data storage service to store key-value data types. It features for storing Key-Value type data with similar way of Cassandra and HBase, faster query, and no restriction for input data. These characteristics called Schemeless, and it provides flexibility for non-relational data stores. Geo Replication is one of the features of the Amazon Simple DB. Geo Replication ensures the stability for the failure through improving the accessibility of data in the Simple DB because it is replicated to the data center of Amazon.

Amazon S3 (Simple Storage Service)

If the SDB is the simplest form of key-value pairs for small size of data, Amazon S3 is designed for high-capacity storage for the BLOB data such as files, images, videos, and the other types of large size. It does not limit to the number and the size of data that can be stored while supports from 1byte up to 5GB per record.
