Understanding per 1000 PUT COPY POST or LIST Requests in Amazon S3 Pricing

Understanding Per 1,000 PUT, COPY, POST, or LIST Requests in Amazon S3 Pricing

Amazon S3 (Simple Storage Service) is a popular cloud storage solution provided by Amazon Web Services (AWS). It allows users to store and retrieve data in a scalable, reliable, and cost-effective manner. One of the key aspects of using Amazon S3 is understanding the pricing model, especially the concept of "per 1,000 PUT, COPY, POST, or LIST requests."

What Are PUT, COPY, POST, and LIST Requests?

PUT, COPY, POST, and LIST requests are different types of interactions you can have with the objects stored in your Amazon S3 buckets:

  • PUT Requests: PUT requests are used to upload new objects (files) to an S3 bucket. Each time you upload a new object, it counts as a PUT request. For instance, if you upload 5 files, you'll incur 5 PUT requests.

  • COPY Requests: COPY requests involve copying an object from one location to another within S3. Whether you're moving objects between buckets or within the same bucket, each copy operation is counted as a COPY request.

  • POST Requests: POST requests are an alternate form of PUT requests, particularly used for browser-based uploads. These requests are commonly employed for putting objects in buckets, often through web forms or similar mechanisms.

  • LIST Requests: LIST requests are used to retrieve a list of objects in a bucket. When you request a listing of objects in a bucket, it counts as a LIST request.

How Are These Requests Priced?

Amazon S3 offers a transparent and predictable pricing model. The cost associated with PUT, COPY, POST, and LIST requests is presented as a price per 1,000 requests. For instance, if the cost is $0.005 per 1,000 requests, it means that you'll be charged $0.005 for every 1,000 of these requests you make to your S3 buckets.

Example Scenario:

Let's consider an example to better understand how this pricing works. Imagine you have a web application that allows users to upload images to your S3 bucket. For every image uploaded, a PUT request is generated. If you have 2,000 images uploaded by users in a given month, you would have incurred 2,000 PUT requests.

Using the pricing of $0.005 per 1,000 PUT requests, the cost for these requests would be calculated as follows:

Number of PUT Requests = 2,000 Cost per 1,000 PUT Requests = $0.005

Total Cost = (Number of PUT Requests / 1,000) * Cost per 1,000 PUT Requests Total Cost = (2,000 / 1,000) * $0.005 = $0.01

In this example, the cost for the PUT requests would be $0.01 for that month.


Understanding the concept of per 1,000 PUT, COPY, POST, or LIST requests is crucial when managing costs in Amazon S3. By grasping these request types and their associated pricing, you can better estimate and control your expenses while utilizing the powerful features of Amazon S3 for your storage needs.
