Describe Azure storage services Flashcards
What are the primary benefits of using Azure Storage services?
Azure Storage services offer durability, high availability, scalability, and security. They are also managed by Microsoft, relieving users of hardware maintenance and offering accessibility from anywhere.
Describe the main function of Azure Blob storage and provide two use case examples.
Azure Blob storage is an object storage solution used to store large amounts of unstructured data like text or binary files. Examples include serving images to a website or storing media for streaming.
How does Azure File storage differ from Azure Blob storage, and what are its key access protocols?
Azure File storage provides managed file shares accessible via SMB or NFS protocols, unlike Blob’s object storage. This allows users to map a network drive or mount a share like a traditional file server.
Explain the purpose of Azure Queue storage and how it can be integrated into an application architecture.
Azure Queue storage is a message queuing service for reliable communication between application components. It enables asynchronous processing, like triggering an action when a customer uploads a form.
What are the different storage access tiers for Azure Blobs, and when would you use each?
The storage access tiers are Hot, Cool, Cold, and Archive, used to balance cost and accessibility. Hot is for frequently accessed data, Cool is for infrequently accessed data stored for at least 30 days, Cold for data accessed even less, and Archive is for rarely accessed, long-term data.
Describe the functionality of Azure Migrate and its role in moving to the cloud.
Azure Migrate is a service to manage assessment and migration of on-premises infrastructure, applications, and data to the cloud. It offers a single platform and tools for discovery, assessment, and migration.
Explain the purpose and functionality of Azure Data Box, including scenarios where it’s best suited.
Azure Data Box is a physical migration service designed to transfer large amounts of data quickly via shipping physical storage devices. It is ideal for scenarios with limited network connectivity or data volumes exceeding 40 TBs.
What is the difference between Locally Redundant Storage (LRS) and Zone-Redundant Storage (ZRS) in Azure?
LRS replicates data three times within a single data center. ZRS replicates data synchronously across three Azure availability zones in a single region, providing better durability and availability.
How does Geo-Redundant Storage (GRS) protect data, and what is the key limitation of GRS when compared to RA-GRS?
GRS copies data to a secondary region, providing geographic protection against regional outages. Data in the secondary region is not available for reads or writes unless a failover occurs.
Describe the function of Azure File Sync, and how it can enhance access to cloud-based files.
Azure File Sync synchronizes on-premises Windows file servers with Azure Files. This provides local caching and enables cloud tiering to optimize performance and cost.
