Which storage option offers Lifecycle policies for object archival?

Answer - A.

The AWS Documentation mentions the following.

Lifecycle configuration enables you to specify the lifecycle management of objects in a bucket.

The configuration is a set of one or more rules, where each rule defines an action for Amazon S3 to apply to a group of objects.

These actions can be classified as follows:

· Transition actions - In which you define when objects transition to another storage class.

For example, you may choose to transition objects to the STANDARD_IA (IA, for infrequent access) storage class 30 days after creation, or archive objects to the GLACIER storage class one year after creation.

· Expiration actions - In which you specify when the objects expire.

Then Amazon S3 deletes the expired objects on your behalf.

The correct answer is B. Amazon Glacier.

Amazon S3 (Simple Storage Service) is a highly scalable and durable object storage service that can store and retrieve any amount of data from anywhere on the web. It is designed to provide 99.999999999% durability and 99.99% availability of objects over a given year. Amazon S3 provides a range of storage classes, including Standard, Infrequent Access (IA), and One Zone-Infrequent Access (One Zone-IA), that customers can use to optimize costs for their specific use cases. However, Amazon S3 does not offer a dedicated archival storage class.

Amazon Glacier is a dedicated archival storage service that provides secure, durable, and low-cost storage for data archiving and long-term backup. Amazon Glacier is designed to provide 99.999999999% durability and is optimized for infrequently accessed data that can be stored for months, years, or even decades. Amazon Glacier offers a range of storage options, including standard, expedited, and bulk retrievals, and customers can define their own retrieval policies to meet their specific recovery time and cost requirements.

Lifecycle policies are used to automatically transition objects between different storage classes or delete them when they are no longer needed. Amazon S3 provides the option to define lifecycle policies that can be used to transition objects to infrequent access storage classes or delete them after a certain period of time. However, Amazon S3 does not offer the option to move objects to archive storage.

Amazon Glacier provides the option to define lifecycle policies that can be used to transition objects between different storage classes, including Standard, Expedited, and Bulk, or delete them after a certain period of time. The lifecycle policies in Amazon Glacier can be used to move objects to archive storage after a certain period of time, which helps customers reduce storage costs and optimize the use of their storage resources.

Amazon Storage Gateway is a hybrid storage service that enables on-premises applications to use cloud storage seamlessly. Amazon Storage Gateway supports file, volume, and tape-based storage solutions, but it does not provide the option to define lifecycle policies that can be used to move objects to archive storage.

Amazon EBS (Elastic Block Store) is a block-level storage service that provides persistent storage volumes for use with Amazon EC2 instances. Amazon EBS is designed to provide low-latency and consistent performance for mission-critical applications. However, Amazon EBS does not provide the option to define lifecycle policies that can be used to move objects to archive storage.
