Amazon S3 Glacier vs Glacier Storage Class

Question

This question might look like an easy/idiot/beginner question but I'm really confused between both of them.

Why do I need to use Amazon S3 Glacier if I can use the normal S3 Bucket and just change the storage class of the objects inside to Glacier manually or by using Lifecycle rule?

Thanks in advance,

The Amazon S3 Glacier storage classes are designed specifically for data archiving, offering the best performance, retrieval flexibility, and cost-effective archive storage in the cloud. All S3 Glacier storage classes offer almost infinite scalability and are designed for data durability of 99.999999999 percent (11 nines). The S3 Glacier storage classes provide the quickest access to your archive material as well as the most cost-effective archive storage in the cloud.

Three archive storage classes are available, each suited for various access patterns and storage length. Choose the S3 Glacier Instant Retrieval storage type for archive data that requires quick access, such as medical photographs, news media assets, or genomics data. Choose S3 Glacier Flexible Retrieval (previously S3 Glacier) for archive data that does not require immediate access but requires the flexibility to retrieve huge quantities of data at no cost, such as backup or disaster recovery use cases. S3 Glacier Deep Archive will help you save even more money on long-term archive storage like compliance archiving and digital media preservation.
