Big data analytics, data warehouses, Internet of Things, databases, and backup and archive applications all rely on some form of data storage architecture.<\/span><\/p>\n<p><span lang=\"EN-US\">Cloud storage is typically more reliable, scalable, and secure than traditional on-premises storage systems. AWS offers a complete range of cloud storage services to support both application and archival compliance requirements.<\/span><\/p>\n<p><span lang=\"EN-US\">Amazon Web Services (AWS) storage solutions are designed to deliver secure, scalable, and durable storage for businesses looking to achieve efficiency and scalability within their backup and recovery environments, without the need for an on-premises infrastructure.<\/span><\/p>\n<p><span lang=\"EN-US\">Amazon Web Services (AWS) provides low-cost data storage with high durability and availability.

You can easily move cold data to Amazon Glacier using lifecycle management rules on data stored in Amazon S3. You can also use Amazon S3 cross-region replication to automatically copy objects across S3 buckets in different AWS Regions asynchronously, providing disaster recovery solutions for business continuity.<\/span><\/p>\n<p>Once data is stored in S3, it can be automatically tiered into lower cost, longer-term cloud storage classes like S3 Standard &#8211; Infrequent Access and Amazon Glacier for archiving. S3 Standard &#8211; IA is ideal for data that is accessed less frequently, but requires rapid access when needed. Standard &#8211; IA is ideally suited for long-term file storage, older data from sync and share, backup data, and disaster recovery files.<\/p>\n<p><span lang=\"EN-US\">For S3 data, that best practice includes secure access permissions, Cross-Region Replication, versioning and a functioning, regularly tested backup.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Amazon_Glacier\"><\/span><span lang=\"EN-US\">Amazon Glacier<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span lang=\"EN-US\">Amazon S3 enables you to utilize Amazon Glacier\u2019s extremely low-cost storage service as storage for data archival.\u00a0Amazon Glacier is an extremely low-cost storage service that provides secure, durable, and flexible storage for data backup and archival.<\/span><\/p>\n<p><span lang=\"EN-US\">Standard retrievals allow you to access any of your archives within several hours.

Snapshots are incremental backups, which means that only the blocks on the device that have changed after your most recent snapshot are saved. This minimizes the time required to create the snapshot and saves on storage costs. When you delete a snapshot, only the data unique to that snapshot is removed. Active snapshots contain all the information needed to restore your data to a new EBS volume.<\/span><\/p>\n<figure id=\"attachment_27460\" aria-describedby=\"caption-attachment-27460\" style=\"width: 1600px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2024\/05\/CreatingaSnapshot.png\"><img decoding=\"async\" src=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2024\/05\/CreatingaSnapshot.png\" alt=\"Creating an EBS Snapshot\" width=\"1600\" height=\"724\" class=\"size-full wp-image-27460\" \/><\/a><figcaption id=\"caption-attachment-27460\" class=\"wp-caption-text\">Creating an EBS Snapshot<\/figcaption><\/figure>\n<p align=\"center\"><b><i><span lang=\"EN-US\">Figure #1.

Creating this DB snapshot on a Single-AZ DB instance results in a brief I\/O suspension that can last from a few seconds to a few minutes, depending on the size and class of your DB instance. Multi-AZ DB instances are not affected by this I\/O suspension since the backup is taken on the standby.<\/span><\/p>\n<figure id=\"attachment_27462\" aria-describedby=\"caption-attachment-27462\" style=\"width: 1548px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2024\/05\/DBSnapshot.png\"><img decoding=\"async\" src=\"https:\/\/www.whizlabs.com\/blog\/wp-content\/uploads\/2024\/05\/DBSnapshot.png\" alt=\"Creating a DB snapshot\" width=\"1548\" height=\"424\" class=\"size-full wp-image-27462\" \/><\/a><figcaption id=\"caption-attachment-27462\" class=\"wp-caption-text\">Creating a DB snapshot<\/figcaption><\/figure>\n<p align=\"center\"><b><span lang=\"EN-US\">Figure #3. Creating a DB Snapshot<\/span><\/b><\/p>\n<p><span lang=\"EN-US\">When you create a DB Snapshot, you need to identify which DB instance you are going to back up, and then give your DB snapshot a name so you can restore from it later. If you have IAM database authentication enabled, then this setting is inherited from the source DB instance.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"RDS_High_Availability_Multi-AZ\"><\/span><span lang=\"EN-US\">RDS High Availability (Multi-AZ)<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span lang=\"EN-US\">Amazon RDS provides high availability and failover support for DB instances using Multi-AZ deployments. Amazon RDS uses several different technologies to provide failover support. Multi-AZ deployments for Oracle, PostgreSQL, MySQL, and MariaDB DB instances use Amazon&#8217;s failover technology. SQL Server DB instances use SQL Server Mirroring. Amazon Aurora instances stores copies of the data in a DB cluster across multiple Availability Zones in a single region, regardless of whether the instances in the DB cluster span multiple Availability Zones<\/span><\/p>\n<p><span lang=\"EN-US\">In a Multi-AZ deployment, Amazon RDS automatically provisions and maintains a synchronous standby replica in a different Availability Zone. The primary DB instance is synchronously replicated across Availability Zones to a standby replica to provide data redundancy, eliminate I\/O freezes, and minimize latency spikes during system backups. Running a DB instance with high availability can enhance availability during planned system maintenance, and help protect your databases against DB instance failure and Availability Zone disruption.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Important_Points_to_Remember_for_the_AWS_Certified_SysOps_Administrator_%E2%80%93_Associate_Certification_exam\"><\/span><span lang=\"EN-US\">Important Points to Remember for the AWS Certified SysOps Administrator \u2013 Associate Certification exam<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul type=\"disc\">\n<li><span lang=\"EN-US\">AWS <\/span><span lang=\"EN-US\">provides low-cost data storage with high durability and availability<\/span><b><span lang=\"EN-US\"><\/span><\/b><\/li>\n<\/ul>\n<ul>\n<li><span lang=\"EN-US\"> <\/span><span lang=\"EN-US\">Amazon S3 is often used as a highly durable, scalable, and secure solution for backup and archiving of critical data<\/span><\/li>\n<li><span lang=\"EN-US\"> <\/span><span lang=\"EN-US\">Amazon Glacier is a secure, durable, and extremely low-cost cloud storage service for data archiving and long-term backup.
