Patterns for enterprise data sharing at scale
Data sharing is becoming an important element of an enterprise data strategy. AWS services like AWS Data Exchange provide an avenue for companies to share or monetize their value-added data with other companies. Some organizations would like to have a data sharing platform where they can establish a collaborative and strategic approach to exchange data with a restricted group of companies in a closed, secure, and exclusive environment. For example, financial services companies and their auditors, or manufacturing companies and their supply chain partners. This fosters development of new products and services and helps improve their operational efficiency.
Data sharing is a team effort, it’s important to note that in addition to establishing the right infrastructure, successful data sharing also requires organizations to ensure that business owners sponsor data sharing initiatives. They also need to ensure that data is of high quality. Data platform owners and security teams should encourage proper data use and fix any privacy and confidentiality issues.
This blog discusses various data sharing options and common architecture patterns that organizations can adopt to set up their data sharing infrastructure based on AWS service availability and data compliance.
Organizations operate across a spectrum of security compliance constraints. For some organizations, it’s possible to use AWS services like AWS Data Exchange. However, organizations working in heavily regulated industries like federal agencies or financial services might be limited by the allow listed AWS service options. For example, if an organization is required to operate in a Fedramp Medium or Fedramp High environment, their options to share data may be limited by the AWS services that are available and have been allow listed. Service availability is based on platform certification by AWS, and allow listing is based on the organizations defining their security compliance architecture and guidelines.
The kind of data that the organization wants to share with its partners may also have an impact on the method used for data sharing. Complying with data classification rules may further limit their choice of data sharing options they may choose.
The following are some general data classification types:
The following is a sample decision tree that you can refer to when choosing your data sharing option based on service availability, classification type, and data format (structured or unstructured). Other factors like usability, multi-partner accessibility, data size, consumption patterns like bulk load/API access, and more may also affect the choice of data sharing pattern.
In the following sections, we discuss each pattern in more detail.
AWS Data Exchange makes exchanging data easier, helping organizations lower costs, become more agile, and innovate faster. Organizations can choose to share data privately using AWS Data Exchange with their external partners. AWS Data Exchange offers perimeter controls that are applied at identity and resource levels. These controls decide which external identities have access to specific data resources. AWS Data Exchange provides multiple different patterns for external parties to access data, such as the following:
The following diagram illustrates an example architecture.
With AWS Data Exchange, once the dataset to share (or sell) is configured, AWS Data Exchange automatically manages entitlements (and billing) between the producer and the consumer. The producer doesn’t have to manage policies, set up new access points, or create new Amazon Redshift data shares for each consumer, and access is automatically revoked if the subscription ends. This can significantly reduce the operational overhead in sharing data.
You can use this pattern in cases where both the producer and consumer are on the AWS Services with an AWS account that is enabled to use AWS Lake Formation. This pattern provides a no-code approach to data sharing.
