What can we do with it, assuming we can write some simple programs?
This section describes key concepts and terminology you need to understand to use Amazon S3 effectively. They are presented in the order you will most likely encounter them.
Buckets A bucket is a container for objects stored in Amazon S3. Every object is contained in a bucket. You can configure buckets so that they are created in a specific region. For more information, see Buckets and Regions. You can also configure a bucket so that every time an object is added to it, Amazon S3 generates a unique version ID and assigns it to the object.
For more information, see Versioning. For more information about buckets, see Working with Amazon S3 Buckets. Objects Objects are the fundamental entities stored in Amazon S3.
Objects consist of object data and metadata. The data portion is opaque to Amazon S3. The metadata is a set of name-value pairs that describe the object. These include some default metadata, such as the date last modified, and standard HTTP metadata, such as Content-Type. You can also specify custom metadata at the time the object is stored.
An object is uniquely identified within a bucket by a key name and a version ID. For more information, see Keys and Versioning.
Keys A key is the unique identifier for an object within a bucket. Every object in a bucket has exactly one key.
Every object in Amazon S3 can be uniquely addressed through the combination of the web service endpoint, bucket name, key, and optionally, a version. For example, in the URL http: For more information about object keys, see Object Keys.
Regions You can choose the geographical region where Amazon S3 will store the buckets you create. You might choose a region to optimize latency, minimize costs, or address regulatory requirements. Objects stored in a region never leave the region unless you explicitly transfer them to another region.
For example, objects stored in the EU Ireland region never leave it.Programming for the Web has become a hot topic since the rise of “Web ”, which focuses on user-generated content on web sites. It has always been possible to use Python for creating web sites, but it was a rather tedious task.

If you are new to Python programming or in computer programming in general, it would certainly be important for you to get some information on the advantages and disadvantages of the language and understand why would somebody want to use it.
how to create a windows service in python (Python recipe) The following code snippet shows you have to create a windows service from a python script. The most important thing here is the username and password, if you ignore supplying these the server will never start and you will get a message saying that the service has not .
