Introduction
Azure Storage is a cornerstone of cloud solutions, offering secure, scalable, and versatile storage capabilities. This blog will guide you through Module 7 of the AZ-104 certification, focusing on mastering Azure Storage. Dive into key topics and subtopics to ensure you’re exam-ready and confident in real-world scenarios.
1. Configure Storage Accounts
- Explore Azure Storage Services: Understand the services available for file storage, messaging, and structured or unstructured data:Azure Containers, Azure Tables, Azure Queues, Azure Files.
- Determine Storage Account Types: General Purpose v2, Premium Block Blobs, Premium File Shares, Premium Page Blobs. Read more
- Determine Replication Strategies: Learn replication strategies for redundancy and disaster recovery: LRS, ZRS, GRS, RA-GRS and GZRS. Read more
- Access and Secure Storage Endpoints: Use firewalls, private endpoints, and virtual networks for secure access. Read more
- Unique URL address based on storage type and custom domains. Read more
2. Configure Blob Storage
- Implement Blob Storage: Use cases for unstructured data storage.
- Create Blob Containers: Define containers and manage access levels. Read more
- Create Blob Access Tiers: Optimize costs with Hot, Cool, Cold, and Archive tiers. Read more
- Add Blob Lifecycle Management Rules: Transition blobs to lower-cost tiers (or delete) automatically. Read more
- Determine Blob Object Replication: Configure replication to minimize latency and improve efficiency. Read more
3. Configure Storage Security
- Review Storage Security Strategies: Implement encryption and secure access:
- Storage Service Encryption (SSE)
- Azure Disk Encryption
- Authentication via Entra ID and RBAC
- Create and Manage Shared Access Signatures (SAS)
- Generate SAS tokens to delegate access.
- Use URI and SAS parameters for secure sharing.
- Determine Storage Service Encryption
- Use Microsoft or Customer Managed Keys for encryption.
- Apply Best Practices for Storage Security
- Always use HTTPS.
- Monitor usage with Storage Analytics.
- Set specific resource access permissions.
4. Configure Azure Files
- Compare Azure Files and Blob Data: Evaluate use cases for each type of storage.
- Create and Manage File Shares: Configure quotas and enable secure transfer using SMB 3.0.
- Create File Share Snapshots: Enable snapshots for backup and recovery.
- Implement Soft Delete for Azure Files: Recover data from accidental deletions.
- Use Azure Storage Explorer: Manage storage resources and SAS tokens using the Azure portal or Storage Explorer tool.
5. Reference Tools and Techniques
- AzCopy Utility
- Command-line tool for data transfer.
- Supports authentication with Entra ID or SAS tokens.
- Azure File Sync
- Azure File Sync centralizes file shares in Azure Files while allowing on-premises servers to cache frequently accessed data locally. It optimizes storage with cloud tiering, enabling cost-efficient scalability, multi-site synchronization, and seamless disaster recovery, making it ideal for hybrid storage scenarios. Read more
- Data Import/Export Service
- The Azure Data Import/Export Service uses customer-provided SATA drives for offline data transfers, while Azure Data Box offers Microsoft-managed, secure appliances designed for larger-scale, enterprise-grade data migrations with greater capacity and simplicity. Import/Export jobs are now integrated into the Azure Data Box resource in the Azure portal.
Conclusion
Module 7 of AZ-104 is a crucial step in understanding Azure Storage’s robust features and real-world applications. Whether it’s configuring storage accounts, optimizing costs, or securing your data, these skills are essential for any Azure administrator. Practice the labs and sandbox exercises to reinforce your knowledge and prepare for the AZ-104 exam with confidence.
