1. Leave the data in STD: $15,185

2. Move current unlinked (>=128 KB) to infrequent Access*: $14,394

   1. Using the unlinked data >= 128KB: (680T - 91U) in standard + 91U in IA

   2. Consider an avg of 28,808/month unlinked files for moving data to IA (PUTs cost)

3. Eventually move unlinked data to Glacier deep archive*: $13,323

   1. Using the unlinked data >= 128KB: (680T - 91U) in standard + 91U in Glacier Deep Archive

   2. Consider an avg of 28,808/month unlinked files for moving data to IA (PUTs cost)

   3. Consider the avg of 28,808/month for lifecycle transitions to Glacier and Glacier Deep Archive

4. Move everything to INT**: $11,775

   1. Consider 44% in INT-Standard (300H/680T)

   2. Consider 56% in INT-IA ((680T-300H)/680T)

   3. Includes the 44M objects monitoring fee

5. Move to INT + unlinked eventually in INT-deep archive**: $10,734

   1. Assumes that unlinked data is part of the cold data

   2. Consider 44% in INT-Standard (300H/680T)

   3. Consider 43% in INT-IA ((680TD - 300H - 91U)/680T)

   4. Consider 13% in INT-Deep Archive (91U/680T)

   5. Includes the 44M objects monitoring fee

   6. Assumes that we have 28,808 tags per month (GET/PUT request + tag costs)

6. Move to INT + delete unlinked data**: $10,544

   1. Assumes that unlinked data is part of the cold data

   2. Consider 50% in INT-Standard (300H/(680T - 91))

   3. Consider 50% in INT-IA

   4. Includes the 44M - 8M objects monitoring fee, no tags, no lifecycle transitions

* Note that it does not include the initial cost of moving 2M objects to IA

** Note that it does not include the initial fee for moving all the 44M objects to INT of about $400 (through a lifecycle transition), once an object is in INT there are no fees for other transitions

It is clear that just moving everything to INT is cost effective for our use case where our access patterns are unknown. On top of it archiving unlinked data might be worth it even though the cost savings is not comparable to just using the INT storage class, we have around 1TiB of data each month in average that gets unlinked.
