S3 Egress Costs

You may have learned by now that Telnyx Cloud Storage doesn’t charge anything for egress fees, but what does this really mean for your business? In this article, we’ll discuss what egress costs are, how they’re calculated and the exact cost benefits of swapping to Telnyx Cloud Storage from Amazon Simple Storage Service (S3). If you missed it, we also shared an introduction to Telnyx Storage.

What are egress costs?

Egress costs, in the context of cloud storage services, refer to the fees incurred when data is transferred out of the storage service to another location, service, or end-user. These costs are an important aspect of using cloud storage solutions, as they can significantly impact the overall expense of managing and accessing stored data.

How are egress costs calculated by S3?

Amazon S3 calculates egress costs based on several factors:

  • Amount of data transferred: Egress fees depend on the total volume of data being transferred out of Amazon S3. Larger data transfers typically result in higher costs.
  • Destination of the transferred data: Amazon S3 charges different rates for data transfers depending on the destination. Transfers within the same region or to Amazon Web Services (AWS) services usually have lower fees compared to transfers across regions or to non-AWS services. Egress costs can vary depending on the specific region where the data is being transferred from and the destination of the data.
  • Data transfer speed: Faster data transfer rates often come with higher costs. Businesses that require high-speed data access or transfers may face higher egress costs.

Egress costs can get expensive quickly, but S3 alternative, Telnyx Cloud Storage, removes that hurdle

Storing data in the cloud is half the battle—modern, rich experiences and applications are built around serving files and content to users across the internet.

Unfortunately, Amazon S3 charges a premium for this critical functionality, which severely limits the scaling ability of applications and experiences built on S3. A comparison of egress fees between Amazon S3 and Telnyx Storage is shown in the table below:
