What is NOT a feature of Amazon S3?

Amazon S3 (Simple Storage Service) is a scalable object storage service designed for data storage, retrieval, and analysis. It boasts several features that facilitate efficient data management, which include versioning, archival storage, and data encryption.

Versioning in S3 is a powerful feature that allows users to keep multiple versions of an object in the same bucket. This is beneficial for maintaining data integrity and recovering from unintended deletions or overwrites.

Archival storage refers to Amazon S3's capability to store infrequently accessed data in a cost-effective manner. S3 offers a specific storage class called S3 Glacier, which is tailored for long-term archival storage, enabling users to store data at lower costs while still having the option for retrieval when necessary.

Data encryption is an essential aspect of data security in Amazon S3. S3 provides several options for encrypting data at rest and in transit, ensuring that sensitive data remains protected regardless of its state.

In contrast, automatic scaling of virtual machines (VMs) pertains to Amazon EC2 (Elastic Compute Cloud), not S3. While S3 does offer highly scalable storage, it does not involve VM management or automatic scaling features. Thus, the correct answer identifies a feature that is not associated with Amazon S3
