Storage is the cheapest of all options, but you pay for data transfer. S3 Glacier Deep Archive: Designed for very infrequent access, something as 1–2 times a year.

Storage is cheap, but you pay for data transfer. This is the place to store backups or old versions.

Data can be retrieved between a few mins and a few hours. As the name suggests, It’s not backed up by a second Zone so it should be used only for data that is replicable, something like a second backup. S3 One Zone-IA: Place for less frequent data access. It’s a lower storage cost, but you pay for data retrieval. S3 Standart-IA -Frequent Access: For data that is retrieved less frequently but requires a rapid transfer.

You also pay per 1000 lifecycle transaction request so if you have a lot of data you don’t want to be moving back and forth between storage classes too much so that might not be the best option for you.

You might pay slightly extra for the monitoring, but it’s worth it if you really don’t know your data and don’t have set up Lifecycle Rules( more on those below). It will automatically determine which data is less frequently accessed and move it for you. S3 Intelligent-Tiering This tier is used for unknown or changing access patterns. S3 Standard - General Purpose This is the most common one and the one you will start off by default. What needs to be considered for your choice of a Storage Class is the lifecycle of the data and frequency of access for a longer period. Putting (or moving) the data in the correct one will be a driving factor of cost. Storage Classes are the core of S3 and are mostly an overlooked option, as people go with the default - S3 Standard General Purpose class that just does the job.
