Azure storage
- 1. Azure Storage • by Adam Skibicki
- 2. Who am I? • Billennium .NET developer • Speaker • programowanienaostro.pl • https://github.com/adamki bicki
- 4. Account types Standard • GPv2 Premium (only LRS) • GPv2 (page blobs, disks) • File Storage • Block Blob Storage
- 5. Redundancy • LRS • ZRS • GRS • RA-GRS
- 9. Blob storage • Serving files directly to browser • Distributed access • Streaming video, audio • Logs • Backups, restore, disaster recovery, archive data
- 10. Structure
- 11. Block blob • Consists of blocks up to 100 MB each • We operate on entire blocks • We cannot modify part of the block
- 12. Page blob • Consists of 512-byte pages • Random read and write • Virtual machine disks are based on them
- 13. Append blob • Consists of blocks up to 4 MB each • Cannot modify or delete single blocks • Each write operation creates new block at the end of blob
- 14. Blob access tiers • Hot – frequently accessed data • Cool – infrequently accessed data • Archive – flexible latency (several hours)
- 15. Storage per GB/month • Hot – $0.0196 • Cool –$0.0100 • Archive – $0.0018
- 16. 10k reads • Hot – $0.043 • Cool –$0.100 • Archive – $6.000 • Archive High Priority - $32.50
- 17. Lifecycle management • Reduce storage costs • Automate migrating blobs between access tiers • Automate deletions and snapshots • Run once per day
- 18. Early deletion Payment for reserved data storage time.
- 19. Snapshots • Built in blob versioning • Readonly blob copies
- 20. Soft delete • Snapshots before blob modification or deletion
- 21. Static hosting • Static website • JS, CSS, HTML. • Frontend – SPA, backend - API
- 22. Table storage • NoSQL • Key-value pairs • Schemaless • Structured data • No relations
- 23. Use scenarios • Large data volumes • Cheaper than SQL database • It depends
- 24. Structure
- 25. Table structure • Partition key • Row key • Timestamp • Up to 252 other columns • Max. 1 MB per entity
- 26. Partitioning • Blob service – blob • Queue service – queue • Table service – partition key
- 27. Partition key • Key selection problem • Querying in scope of single partition key value are atomic
- 28. Row key • Idenitfies record in partition
- 29. • More partitions – scaling • Problems with atomic operations and data consistency • Tradeoff Partitioning
- 30. Entity Group Transactions • Built in atomic batch transactions (up to 100 entities per transaction) • Operates on records in single partition
- 31. • Simple queue • Max. 64 KB per message • Max. 7 days • FIFO – not guaranteed • Other services - Event Grid, Event Hub, Service Bus Queue storage
- 32. Structure
- 33. Operations • Put • Get • Peek • Delete • Clear • Update
- 34. File service • Fully managed file share in cloud • Can be connected with every system (Windows, MacOS, Linux)
- 35. Use scenarios • File server • Lift and shift • Cloud development (sharing application settings, diagnostic data and tools)
- 36. Structure • File system • Consists of file shares (like blob containers)
- 37. Shared Access Signature (SAS) • Generated URI • Permissions for selected resources • Time range • Cannot be directly canceled
- 38. Stored Access Policy • Policy with similar settings as SAS • SAS can be based on it • Easily cancelable • Cannot be set on Storage Account level (like SAS)
- 39. Storage analytics • Already defined tables and blob containers • 20 TB storage independent of storage account limits • Some analytics operations are billed
- 40. The end
