Choose Azure Blob Storage, Azure Files, or managed disks by matching data interface, sharing, performance, security, and recovery.
What you will be able to do
- Explain the five core cloud decisions involved in azure blob files and managed disks.
- Choose a cloud resource or configuration that matches a stated workload requirement.
- Interpret provider state, workload behavior, and operational evidence before changing broader cloud state.
- Apply an inventory, select, configure, verify, recover, and document workflow to a realistic cloud decision.
01
Build the Cloud Decision Map
Choose Azure Blob Storage, Azure Files, or managed disks by matching data interface, sharing, performance, security, and recovery.
Cloud services combine provider-managed layers with customer-controlled configuration. A useful design keeps workload need, resource scope, identity, network path, data, health, cost, and recovery visible instead of relying on a product name.
Start with an inventory and read-only evidence. Record the account or project, location, resource identifier, owner, configuration source, dependencies, expected behavior, and current observation before changing state.
02
Blob objects
Azure Blob Storage keeps unstructured data as objects in containers accessed through service interfaces. It answers one distinct architecture or operating question within azure blob files and managed disks.
Use blobs for application objects, archives, logs, media, and data-lake patterns. Keep the target, location, identity, configuration, and observed outcome together so another person can reproduce the reasoning.
Respect this boundary: Do not expect block-device or ordinary shared-filesystem behavior from blob storage. The expected evidence is a representative blob completes its required read and lifecycle path.
04
Managed disk
An Azure managed disk provides block storage used by Azure virtual machines. It answers one distinct architecture or operating question within azure blob files and managed disks.
Choose disk class, size, performance, encryption, caching, and recovery together. Keep the target, location, identity, configuration, and observed outcome together so another person can reproduce the reasoning.
Respect this boundary: Do not detach, resize, or remove a live disk without filesystem and rollback checks. The expected evidence is the vm sees the expected capacity and application performance.
05
Storage access
Azure Storage access can combine Entra authorization, roles, service credentials, network controls, and scoped delegation. It answers one distinct architecture or operating question within azure blob files and managed disks.
Prefer identity-based access and scope permissions to the required data operation. Keep the target, location, identity, configuration, and observed outcome together so another person can reproduce the reasoning.
Respect this boundary: Do not place long-lived storage keys in source code or support records. The expected evidence is the intended identity succeeds and an unauthorized identity is denied.
06
Storage recovery
Recovery combines redundancy, versions, snapshots, soft deletion, backup, and tested restore according to the service. It answers one distinct architecture or operating question within azure blob files and managed disks.
Restore a representative item or volume into an isolated target. Keep the target, location, identity, configuration, and observed outcome together so another person can reproduce the reasoning.
Respect this boundary: Stop when retention, encryption access, or recovery timing is unknown. The expected evidence is the isolated restore meets the written recovery objective.
07
Verify One Cloud Change
Before changing cloud state, name the exact resource, required authorization, user impact, expected signal, cost effect, and recovery path. Preview the scope with an inventory or policy view and protect data or configuration that cannot be recreated safely.
Make one narrow change and stop. If the provider response, location, identity, dependency, or effective configuration differs from the plan, preserve that evidence and reassess instead of adding unrelated changes.
A successful API response or portal notification proves only that an operation was accepted. Repeat the original workload path, inspect health and security signals, verify the resulting resource state independently, and remove temporary access or test resources.
08
Recap Before Practice and Prove
Start with blob objects. Use blobs for application objects, archives, logs, media, and data-lake patterns. Confirm that a representative blob completes its required read and lifecycle path.
Keep azure files share separate. Use a file share when clients require a shared hierarchical namespace and compatible permissions. Respect this boundary: do not assume every workload safely supports concurrent access to one share.
Use managed disk as its own decision. Choose disk class, size, performance, encryption, caching, and recovery together. Preserve the resulting evidence.
Before a broader change, review storage access. Prefer identity-based access and scope permissions to the required data operation. Stop when do not place long-lived storage keys in source code or support records.
Finish with storage recovery. Restore a representative item or volume into an isolated target. Record the final state, health signal, recovery boundary, owner, and next decision.
