AMAZON CONFIDENTIAL
CSP Transparency Statement for Amazon Simple Storage Service (Amazon S3)
a4
Version 1.0
50
Date: 10 May 2021

01
This Transparency Statement is designed to assist AWS customers in anticipating their switching and
porting needs for Amazon Simple Storage Service (“S3”) and in conformance with applicable SWIPO
Code of Conduct for Data Portability and Cloud Service Switching for Iaas Cloud Services requirements.
References to defined SWIPO terms contained herein are used exactly as they appear in the SWIPO
Common Terminology (Version 2020, Date: 08-07-2020).
c2
At AWS, customers (“Cloud Service Customers” or “CSCs”) have full control over the switching and
porting process for S3, and as a result, have significant flexibility to adopt a plan best-suited for their
needs. Under the Shared Responsibility Model, Amazon S3 relies on receiving a CSC’s instructions before
acting on a CSC’s Infrastructure Artefacts.

S3 has publicly available documentation that provides CSCs with in-depth information on the
features/configuration settings available to port Infrastructure Artefacts to and from S3. For a full list of
supported features, please see:

Amazon S3 service is an object storage service that supports APIs that allow a CSC to handle CSC-tocloud-service and cloud-service-to-CSC use cases by uploading/downloading Infrastructure Artefacts
through secure connection channels. S3 provides public documentation that provides CSCs in-depth
information on the features/configuration settings available in the service for these purposes.
The S3 supports many connectivity options that a CSC can leverage to secure the channel for
communication. These are detailed in the service documentation. Additionally, S3 provides CSCs with
the ability to perform client-side encryption before uploading Infrastructure Artefacts to the cloud. CSCs
can leverage the publicly available documentation links below to learn more about the networking and
client-side encryption offered by S3. For details, please see:
https://docs.aws.amazon.com/AmazonS3/latest/dev/inter-network-traffic-privacy.html

CSCs looking to transfer their Infrastructure Artefacts from one cloud service to another can download,
make transformations on the data as needed, and move Infrastructure Artefacts to the destination CSP
or download Infrastructure Artefacts from the source CSP, make transformations on the data as needed,
and upload to AWS. To facilitate porting, S3 CLI/APIs support input/outputs in both JSON and YAML
formats.

S3 supports the REST API, and it is recommended that CSCs use either the REST API or the AWS SDKs. S3
is designed to be highly flexible. CSCs can store any type and amount of data they want; read the same
piece of data a million times or use the service only for emergency disaster recovery; build a simple FTP
application, or a sophisticated web application.
The functionality described above is supported by a set of clear documentation. For details, please see:

S3 has publicly available documentation (see links above) to help CSCs understand the capabilities of the
user, administrator, and business functions related to the service. With regard to interoperability, S3
supports multiple connection mechanisms that CSCs can leverage to connect to the service. For details,
please see:

Under the Shared Responsibility Model, security and compliance responsibilities are divided between
AWS and the CSC. S3 has change management controls place and has regular testing and deployments,
to ensure that the APIs, console, and service features are operating effectively. The CSC has the
responsibility to implement necessary tests to ensure successful connectivity and porting of
Infrastructure Artefacts to/from S3. CSCs are responsible for managing their S3 Infrastructure Artefacts
in accordance with published best practices:
CSCs can also use information contained in the links below to validate the integrity and completeness of
their Infrastructure Artefacts stored/retrieved when using S3:

CSCs can leverage the performance tuning guidance provided in the link above to manage effectively
their performance needs when using S3. The above link also describes other AWS services and S3
features that can be used by CSCs seeking faster transfer rates.

Finally, AWS offers other cloud migration solutions both online and offline (see links above) that can
handle larger volume of data. CSCs can evaluate and use these solutions based on the applicability to its
requirements.
