Cost efficient way of changing storage class on an S3 bucket

I am aware of this discussion about an indirect way to change the storage class of an S3 bucket.

However, the above solution does not elaborate on whether the

lifecycle policies to automatically transition objects between storage classes

incur any additional cost.

I am assuming it does, since a lifecycle-based transition incorporates requests to the objects.

So my question is

What is the most cost-efficient way of transitioning a bucket (containing millions of small objects) to standard infrequent access storage class?

I assume there is no magic console button that does that for a bucket (and all of its contents).

Is the solution based on lifecycle rule cost optimal?

Lifecycle Transition requests do incur additional costs. The pricing is listed here under "Requests and data retrievals" tab -> "Lifecycle Transition requests (per 1,000 requests)" column.

Whether it's the most cost-efficient way to do it depends on how many objects you have and the average size of your object. You can obtain an S3 inventory report, do some SQL queries on it and do the math yourself in order to make a wise decision.

Just a rule of thumb that I personally use, if the average size of your object is below 50KB, it's probably not a good idea to transition them to SIA. Instead, I would suggest batching them first before transitioning them to SIA.
