4.2 How Do I Create an SFTP in AWS Transfer?

Creating an SFTP server in AWS Transfer involves several steps, including selecting your server options, configuring your SFTP settings, and activating the server. Once active, you can integrate and configure it with Amazon S3 for data storage.
The shell SSH file transfer server uses Amazon API Gateway, which calls AWS Lambda to detect the username and password provided or authenticate via SSH using the private key and public key mechanism. Fortunately, a Cloud Formation template will set up everything for you. You’ll still need to set up security policies using IAM roles and assign them appropriately.

Once everything is set up correctly, you can connect to the SFTP server with any SFTP client using the default port number 22.

5.0 What is SFTP Integration?

SFTP integration is the seamless process of securely transferring files from one system to another. In data integration solutions, it’s not just about moving files but ensuring those files integrate well into the destination system, such as a data warehouse like Snowflake. By utilizing SFTP, organizations can maintain the highest level of data security throughout the data transfer process, thus ensuring that the data remains intact and secure from unauthorized access or data corruption.

Why is Snowflake Data Integration Crucial?

When ingesting data into Snowflake from SFTP, the SFTP integration provides a secure and efficient method for transferring large data volumes. If you use the AWS transfer family server as your SFTP server, you can use AWS storage, which will provide unlimited disk space and satisfy most business needs.
SFTP Snowflake integration enables organizations to get a unified view of their data by combining data from different source systems, including legacy systems and modern data lakes. By integrating SFTP with Snowflake, companies are equipped with a powerful tool that enables the secure, effective management of business data and the breaking down of traditional data silos.

5.1 How to Transfer Data Through SFTP?

Transferring data through SFTP is an organized and secure process. First, you initiate a secure connection between the source (a legacy system, a remote file system, or another data warehouse) and the destination system. This connection is facilitated by an SFTP client using SSH (Secure Shell) cryptographic protocols, ensuring that data remains encrypted during transit and safeguarding it from unauthorized access or tampering.

Steps to Transfer Data:

  1. Initiation: Use an SFTP client to initiate a secure connection with the source system.
  2. Authentication: Both systems authenticate each other through cryptographic keys or passwords. This ensures the source and the destination are verified entities.
  3. Navigate to Source Files: Once the secure connection is established, navigate to the files or data sets you wish to transfer using the SFTP client’s interface.
  4. Execute Transfer: Select the files and execute the transfer. The data is encrypted during this phase, ensuring its integrity and security.
  5. Confirmation and Closing: Both systems send and receive confirmatory messages upon successful transfer. The connection is then terminated, ensuring no residual access remains.

By following these steps, organizations can easily connect and securely transfer business-critical data, making SFTP a key component of any sophisticated data integration system. This level of security and seamless integration is especially beneficial for companies increasingly relying on data warehousing solutions like Snowflake.

6.0 The Ease of Ingesting into Snowflake via S3
