AWS Data Exchange
We all need different types of data to analyze, work on it and learn different things with that data. It is not easy to gather the data according to the need of the particular domain. Amazon Web Services came up with a service named AWS Data Exchange, that makes it easy for AWS customers to find and use third-party data in the AWS Cloud. With the help of datasets from AWS Data Exchange, we enhance data-driven decisions.
About AWS Data Exchange
AWS Data Exchange is a service that helps AWS users easily find, subscribe, and use third-party data in the AWS cloud.
- It provides access to data securely.
- It simplifies the datasets and easy-to-use to consume third-party data products.
- For a subscriber, it provides many products from different data providers.
- The Data Exchange console helps create, manage, and access the data sets across different AWS analytics services.
- For providers, it provides a secure and reliable medium to reach AWS customers. It helps the users to grant existing customers their subscriptions more efficiently.
AWS Data Exchange includes important terminologies, which help in to access it.
- Asset - It is a data object, i.e., a single file. An ID uniquely identifies every asset.
- Revision - When one or more assets are grouped, a revision is created. It is the point-in-time view/update of any data set. An ID uniquely identifies each revision.
- Data Set - When one or more revisions are grouped, a data set is created. It is the logical grouping of data for AWS users. An ID uniquely identifies each data set.
Data Exchange provides hundreds of data products from different third-party data providers. AWS users easily subscribe to the data and export it to Amazon S3. We can use other AWS services to analyze these data sets.
AWS Data Exchange Product
AWS Data Exchange Product is the unit of exchange published by a provider and later available for subscribers. When a provider publishes the product, it is reviewed by AWS guidelines and terms and conditions. Then, this product is listed on the AWS Marketplace and AWS Data Exchange product catalog. Each product is identiﬁed by its product ID.
A product has the following parts:
- Product Details
- Product details include the name of the product, descriptions, logo or image of the product, and contact information for this product.
- The providers complete it.
- Product Offers
- The Product offers to determine the terms and conditions agreed upon by the subscriber to get the product.
- Providers must define a public offer of the product to make it available on the console of the Data Exchange service.
- This Product offer contains prices and durations, an agreement of data subscription, and the option for custom offers.
- Data Sets
- A data set is a dynamic data set that is versioned through revisions.
- In a product, we have one or more data sets.
- The provider decides which revisions within a data set are published. The subscriber access these data sets when they subscribe to a product.
Malware Protection Facility in AWS Data Exchange
Amazon provides us with a very secure environment in all its services. In Data Exchange service, security and compliance are the user's and AWS's responsibility. Every S3 object uploaded by the provider is scanned for malware and viruses before they are made available to the subscribers. In case the scan detects a malware, the S3 object is removed to ensure a safe, secure, and trustworthy environment.
AWS Data Exchange provides different options to secure our data sets. They are:
- Encryption at Rest - This encryption encrypts the data products stored in the service at rest. This option applies by default to the data products whenever we use AWS Data Exchange.
- Encryption in Transit - In this encryption Transport Layer Security (TLS) and client-side encryption are used by AWS Data Exchange. HTTPS protocol is used for communication, so the data is always encrypted in transit. This encryption in transit is configured by default using the Data Exchange service of AWS.
- Restrict Access to Content - In AWS Data Exchange, we can restrict access to any appropriate subset of users. This is done using IAM users and group permissions. We can easily handle this by giving the proper permissions to specific users and groups.
Supported Data Sets in AWS Data Exchange
AWS Data Exchange gives a better approach to making data transactions easier. AWS promotes clarity with the datasets by using these services. It reviews the data types and products, then permitted. Those products that are not permitted are not going to publish and are restricted.
To publish any dataset, AWS sets many guidelines to review those datasets. AWS Data Exchange scans every uploaded object to ensure they follow the guidelines set by AWS. If any user suspects that an AWS Data Exchange product is being used illegally and for abusive purposes, they can report it. AWS provides a form named Report Amazon AWS abuse form for reporting abusive data.
How to Access AWS Data Exchange

Providers can also access AWS Data Exchange by using the following APIs:
- AWS Data Exchange API - This API can be used to carry out CRUD (create, read, update, and delete) operations on the data sets and revisions. In addition, it can also be used for importing and exporting assets between revisions.
- AWS Marketplace Catalog API - The products present on the AWS Data Exchange products catalog and AWS Marketplace can be viewed or updated using this API.
In AWS, Data Exchange charges depend on the actions performed by the users. So let's see the pricing of Data Subscribers and Data Providers.

- AWS Service Costs - AWS charges for the services we use to store, process, or analyze the data products. Any other AWS services we use are billed according to the pricing plan.
For Data providers following are the fees:
Tiered Fulfillment Fees - AWS charges the tiered fulfillment fee for all new subscriptions to the data products. If you have subscribers on your products, you can create your subscription offers to migrate and fulfill subscriptions with AWS customers without additional cost.
