The document discusses how cloud storage can help address challenges with traditional on-premise storage solutions. It provides examples of how cloud storage has helped companies implement tiered storage, distribute content globally for collaboration, and protect off-site data more easily. The cloud offers benefits like flexible capacity, lower costs, and the ability to instantly scale storage. The document also addresses common concerns with cloud security, performance, and data migration.
The Right Approach To Cloud Storage
- 1. The Right Approach to Cloud StorageStephen FoskettInterop, November 2009
- 2. Storage Is Supposed To Be Getting Cheaper!Disk cost is dropping rapidly$250 buys:1994: 2 GB1999: 20 GB2004: 200 GB2009: 2000 GBBut enterprise storage costs keep rising!2
- 4. Physical, Virtual, and Cloud Compute4Server virtualization allows us to combine workloads, buying 30% lessWe really only need this much CPU time……but we have to buy this much on physical servers!Ten servers swing wildly, but there is still lots of idle timeCloud compute services allow us to buy only what we need: 66% less!The CPU load of two servers is even more variableEach server’s CPU load varies throughout the week
- 5. Cloud Storage Is Different5We try to plan for storage capacity growth, but there is always lots of wasted spaceWe would like to buy just what we need…Multiple servers compound the use of storage capacity…but disk drives only come in certain sizes and it takes time to provisionStorage grows continuallyCloud storage services allow us to buy just what we need and can react instantly to new capacity demands
- 6. Cloud Offers Better Access at Lower Cost6SANNASCostReduce CostVTLTapeIncrease AccessibilityAccessibility
- 7. Data Types Suitable for Cloud Storage7
- 8. Public Cloud Storage EconomicsJust-in-Time ProvisioningPlan/buy for usage and not for peak capacityFully Managed StorageManaged GB = Power, space, cabling, racks, monitoring, software, hardware, migration to new media… all includedEnterprise Purchasing and Pricing ModelFlat, bundled price starts at $0.25/GB/month, $3K/TB/yearEnterprise sales, engineering, and support staffConsulting and strategy available8
- 9. Enterprise Cloud Storage: Why Not?9
- 10. Security & ReliabilityNo System is Perfect (including yours)What to look forSecurity audit (by a respected firm or customer)SAS 70 (especially Type 2)Customizable SLA (with remedies)TransparencyEncryption (but who holds the keys?)
- 11. Encryption for Cloud StorageWhere should encryption live?(and who holds the keys?)
- 12. PerformanceCloud storage is not for all dataBut it’s for a lot of data!Cloud-appropriate data:File-based, unstructuredNon mission-criticalValue in keeping it accessibleRequirement to be outside the firewallMulti-user, multi-siteRarely written, frequently read
- 13. IngestionLoading initial data can derail even the best cloud use casesBandwidth is sized to daily requirementsInitial data loading often requires an alternate path Can you ship tapes? Disk arrays?Who manages? Who pays?
- 14. ImplementationAPIs Aren’t “Simple” to IntegrateWhat to look forRobust integrated functionality in applicationsSolutions & integration servicesEnterprise supportStandard storage protocol support
- 15. Paths to the Cloud
- 16. EconomicsTCO is More Than Just $/GBWhat to look atInfrastructure costsConnectivity/network costsSecurity feesHardware utilizationSystem complexitySystem management
- 17. Use Case: Protect Data Off-SiteData must be protected off-site…Local outages and small-scale data losses are frequentRegulations and standards call for off-site storageIT responded by…Shipping backup tapesUsing storage replication featuresBut…Is it really secure?Can you bear the cost and effort for replication?Do backup tape-based solutions even work?
- 18. Offsite Data Protection ASU/NASA Case StudyImages transmitted from moon via satellite3 copies required (2 local 1 offsite)Current offsite tape solution difficult to managed and scale 18Data Receiving ServersExpensive labor intensive
- 19. delivery costsTertiary SecondaryPrimaryUncertain outdated technology
- 20. deteriorating mediaLimited inaccessible
- 21. only used for 1 copyImage Processing Servers
- 22. Optimized management of tertiary dataGained accessibility, security, and integrity19Data Receiving ServersEconomical 40% cost reductionCloud GatewayAPISecure monitored transfer

- 24. can replicate instantlyOffsite Data Protection ASU/NASA Case Study
- 25. Use Case: Tiered StorageStorage capacity just keeps expanding…Larger files + More files = Growing volume of dataIT responded by…Consolidating on SAN and NASTiered storage conceptsHSM and ILMBut…Storage systems getting more complex and expensiveManagement effort keeps growingCost savings aren’t materializing20
- 26. Fulfilling The Promise of Tiered StorageTiered disk storage has not yet lived up to its promiseSmall cost and performance differential between FC and SATA diskTCO is very closeSSD gives extreme performance at high costCloud storage gives massive capacity at low costTiered StoragePerformance and CostCapacity21Tiered StorageSSDFCDiskSATACloud

- 38. Use Case: Scalable CollaborationCompanies are going globalNeed to distribute data between sites and organizationsNew applications need programmable storageMore rich media, massive data volumesConventional systems don’t workSAN and NAS don’t work well over wide area networksRelational databases don’t scale to huge files, datasetsLack of APIs, granular data controlsEverything is firewalled off anyway!24
