S3 is the storage service available through AWS and works similar to the Azure Blob storage.
After purchasing the Direct Connect and then connecting the cloud to the on-prem facility, the Direct Connect gives users a public VIF to connect the on-prem to the cloud storage (the S3 bucket).
However, AWS will advertise all the public IP addresses to the on-prem because the storage/S3 bucket is sitting on a public IP address. This means that anyone on the on-prem can use the Direct Connect to connect to the S3 buckets, causing security concerns.
Aviatrix solves this problem by giving users ways to connect to the S3 bucket without using a public VIF. Instead, the users can use a private VIF, which allows the users to connect to the private IP addresses in the Aviatrix Gateway. This has many benefits, such as additional security and control.
