Ensure that storage accounts are zone or region redundant

Impact: High Category: High Availability

APRL GUID: e6c7e1cc-2f47-264d-aa50-1da421314472

Description:

Redundancy ensures storage accounts meet availability and durability targets amidst failures, weighing lower costs against higher availability. Locally redundant storage offers the least durability at the lowest cost.

Potential Benefits:

High availability and durability for storage

Classic Storage Accounts must be migrated to new Azure Resource Manager resources

Impact: High Category: Service Upgrade and Retirement

APRL GUID: 63ad027e-611c-294b-acc5-8e3234db9a40

Description:

Classic storage accounts will be fully retired on August 31, 2024. If you have classic storage accounts, start planning your migration now.

Potential Benefits:

Avoids service retirement issues

Use premium performance block blob storage for high performance workloads

Impact: Medium Category: Scalability

APRL GUID: 5587ef77-7a05-a74d-9c6e-449547a12f27

Description:

Use premium performance block blob storage instead of standard performance storage for workloads that require fast storage response times and/or high transaction rates.

Potential Benefits:

Optimized cost and performance

Enable Soft Delete to protect your data

Impact: Medium Category: Disaster Recovery

APRL GUID: 03263c57-c869-3841-9e0a-3dbb9ef3e28d

Description:

The soft delete option enables data recovery if mistakenly deleted, while the Lock feature prevents the accidental deletion of the storage account itself, ensuring additional security and data integrity measures.

Potential Benefits:

Prevents accidental data/account loss

Enable versioning for accidental modification and keep the number of versions below 1000

Impact: Low Category: Disaster Recovery

APRL GUID: 8ebda7c0-e0e1-ed45-af59-2d7ea9a1c05d

Description:

Consider enabling versioning for Azure Storage Accounts to recover from accidental modifications or deletions and manage blob operation latency. Microsoft advises maintaining fewer than 1000 versions per blob to optimize performance. Lifecycle management can help delete old versions automatically.

Potential Benefits:

Recover data, manage latency

Enable point-in-time restore for GPv2 accounts to safeguard against data loss

Impact: Low Category: Disaster Recovery

APRL GUID: 1b965cb9-7629-214e-b682-6bf6e450a100

Description:

Consider enabling point-in-time restore for standard general purpose v2 accounts with flat namespace to protect against accidental deletion or corruption by restoring block blob data to an earlier state.

Potential Benefits:

Protects data from loss/corruption

Monitor all blob storage accounts

Impact: Low Category: Monitoring and Alerting

APRL GUID: 96cb8331-6b06-8242-8ce8-4e2f665dc679

Description:

For critical applications and business processes relying on Azure, monitoring and alerts are crucial. Resource logs are only stored after creating a diagnostic setting to route logs to specified locations, requiring selection of log categories to collect.

Potential Benefits:

Enhanced alerting and log analysis

Consider upgrading legacy storage accounts to v2 storage accounts

Impact: Low Category: Scalability

APRL GUID: 2ad78dec-5a4d-4a30-8fd1-8584335ad781

Description:

General-purpose v2 accounts are recommended for most storage scenarios offering the latest features or the lowest per-gigabyte pricing. Legacy accounts like Standard general-purpose v1 and Blob Storage aren't advised by Microsoft but may fit specific scenarios.

Potential Benefits:

Latest features, lowest cost
