Therefore you can choose the region a bucket is located on. The version is optional and can be left out.Īlthough Amazon states that you can access the data from anywhere around the world, for many applications it is crucial to know where the data resides. In the example before javacodegeeks was the bucket, s3. the web service endpoint and photos/geek.jpg the key. Hence the combination of “web service endpoint + bucket + key + version” identifies an object in Amazon S3. Īs buckets span namespaces, every object within a bucket has a unique key. For example, the image file geek.jpg that is located in the bucket javacodegeeks has the URL.

Buckets are also used for access control, usage reporting and transfer charges. You can think of a bucket as a collection of objects that share the same namespace. It is also possible to provide user-defined metadata, like for example the application used to create this object. Next to default information like the last modification date this information also provides standard HTTP metadata like the Content-Type. The metadata is a set of name-value pairs that provide additional information about the object. An object consists of the actual data enriched with metadata. The basic unit to store data inside Amazon S3 is the “object”. Amazon also integrates the storage service into other services, hence it is possible to use the data stored in S3 also for analytical investigations or face recognition.

Beyond that applications may store use data in S3. Projects can store their webpage on Amazon S3 as well as artifacts needed by their application. It offers a simple to use web service interface that can be used by application developers for different use case. On the search for new business models, Amazon was one of the first pioneers to offer the services build for their own business also to customers.Īmazon S3 is therefore a storage service that is designed to store “any amount of data at any time anywhere on the web”. This let Amazon create its own service based infrastructure. While Amazon’s web shop grew over the years, the need for a scalable IT infrastructure became more urgent from day to day.
