A company needs to preserve several petabytes of data for 7 years to meet regulatory compliance. The company's compliance team has tasked a security officer with developing a strategy that ensures the data cannot be altered or deleted. Which of the following solutions offers the most cost-effective approach to achieve this?
Explanation:
The most cost-effective solution for preserving several petabytes of data for 7 years while ensuring no changes or deletions is to create an Amazon S3 bucket and use a lifecycle rule to transition the data to a vault in S3 Glacier, then create a Vault Lock policy. Amazon S3 Glacier is designed for long-term data archiving at a lower cost compared to S3 Object Lock in compliance mode or governance mode. Additionally, the Vault Lock feature of S3 Glacier ensures that the data meets regulatory compliance by preventing any changes or deletions.
