Storage

AWS storage services for object, block, and file storage.

AWS storage services for different types of data and storage requirements, including object, block, and file storage. Key services are Amazon S3 for object storage, Amazon Elastic Block Store (EBS) for block storage, Amazon Elastic File System (EFS) for file storage, and AWS Backup for centralized backup across AWS services.

AWS offers diverse storage solutions for cloud computing needs. Amazon S3 (Simple Storage Service) provides highly durable object storage, ideal for websites, mobile apps, backups, and data lakes. It scales automatically and supports various data types. Amazon EBS (Elastic Block Store) delivers persistent block-level storage volumes for EC2 instances. These work like traditional hard drives and are suitable for databases, file systems, and applications requiring raw block-level storage. Amazon EFS (Elastic File System) offers scalable, elastic file storage for EC2 instances. Multiple instances can access an EFS file system simultaneously, making it perfect for content management systems and shared files. Amazon S3 Glacier provides low-cost archival storage with retrieval options ranging from minutes to hours. It's designed for data that's rarely accessed but must be preserved for compliance or historical purposes. AWS Storage Gateway connects on-premises environments with AWS cloud storage, enabling hybrid storage deployments with local caching. AWS Snow Family includes physical devices for transporting large data volumes to AWS: Snowcone (small, rugged), Snowball (suitcase-sized), and Snowmobile (shipping container). Key storage concepts include: - Durability: The guarantee against data loss - Availability: The accessibility of your data - Scalability: The ability to grow as needs increase - Security: Data protection via encryption, access controls - Cost-efficiency: Various pricing tiers based on access frequency AWS storage solutions help you select the right combination of performance, accessibility, and cost. Each service addresses specific storage needs while integrating with other AWS services, allowing you to build complete storage architectures in the cloud.

CCP - Storage Example Questions

Test your knowledge of Amazon Simple Storage Service (S3)

Question 1

Which of the following is a key characteristic of Amazon S3 Glacier?

Correct Answer: It is designed for long-term archival storage of infrequently accessed data

Amazon S3 Glacier is designed for long-term archival storage of data that is infrequently accessed. It provides a cost-effective solution for storing large amounts of data that do not require frequent or immediate access. The other options are incorrect because they describe characteristics that do not align with the purpose and features of Amazon S3 Glacier. Real-time data access with millisecond latency is not a characteristic of Glacier, as retrieval times range from minutes to hours. While data durability is a feature of Glacier, automatic replication across multiple Availability Zones is not a key characteristic. Configurable retrieval times are a feature of Glacier, but not the primary defining characteristic.

Question 2

What AWS service allows you to create backup plans that define how frequently backups are created and how long they are stored?

Correct Answer: AWS Backup enables you to create backup plans that specify the backup frequency and retention period for your AWS resources.

AWS Backup is the correct answer because it is the AWS service that enables you to centrally manage and automate backups across multiple AWS services. With AWS Backup, you can create backup plans that define the frequency and retention period for your backups. It allows you to specify how often backups should be created and how long they should be stored before being deleted. The other options are incorrect because they serve different purposes: Amazon S3 is a storage service primarily used for storing and retrieving data, but it doesn't provide built-in backup management features. AWS CloudFormation is used for provisioning and managing AWS resources using templates, but it doesn't directly handle backup operations. Amazon CloudWatch is a monitoring service that collects and tracks metrics, but it doesn't create backups or define backup plans.

Question 3

A company wants to ensure that their AWS resources, including Amazon EC2 instances and Amazon RDS databases, are backed up regularly and can be easily restored in case of data loss or disaster. They need a solution that allows them to set backup schedules, define retention periods, and manage backup lifecycles. Which AWS service should they leverage?

Correct Answer: AWS Backup

AWS Backup is the most suitable service for the company's requirements. It provides a centralized solution to automate and manage backups across multiple AWS services, including Amazon EC2 instances and Amazon RDS databases. With AWS Backup, the company can define backup policies, set backup schedules, specify retention periods, and manage the lifecycle of their backups. This ensures regular and reliable backups of their critical resources and enables easy restoration in case of data loss or disaster. Amazon S3 with versioning is primarily used for storing and versioning objects, not for backing up EC2 instances or RDS databases directly. While it can be used to store snapshots, it lacks the native backup management capabilities provided by AWS Backup. Amazon CloudWatch Events and AWS Lambda can be used to automate certain backup tasks, but they require custom code and more manual effort to set up and manage compared to the integrated backup solution offered by AWS Backup. AWS CloudFormation is used for provisioning and managing infrastructure resources, but it does not provide a direct backup solution. It can be used to define backup policies as part of the infrastructure provisioning process, but it lacks the centralized backup management features of AWS Backup.
