The Right Approach To Cloud Storage

  1. 1. The Right Approach to Cloud Storage<br />Stephen Foskett<br />Interop, November 2009<br />
  2. 2. Storage Is Supposed To Be Getting Cheaper!<br />Disk cost is dropping rapidly<br />$250 buys:<br />1994: 2 GB<br />1999: 20 GB<br />2004: 200 GB<br />2009: 2000 GB<br />But enterprise storage costs keep rising!<br />2<br />
  3. 3. Meet The Cloud!<br />Software<br />Platform<br />Infrastructure<br />Products<br />Services<br />
  4. 4. Physical, Virtual, and Cloud Compute<br />4<br />Server virtualization allows us to combine workloads, buying 30% less<br />We really only need this much CPU time…<br />…but we have to buy this much on physical servers!<br />Ten servers swing wildly, but there is still lots of idle time<br />Cloud compute services allow us to buy only what we need: 66% less!<br />The CPU load of two servers is even more variable<br />Each server’s CPU load varies throughout the week<br />
  5. 5. Cloud Storage Is Different<br />5<br />We try to plan for storage capacity growth, but there is always lots of wasted space<br />We would like to buy just what we need…<br />Multiple servers compound the use of storage capacity<br />…but disk drives only come in certain sizes and it takes time to provision<br />Storage grows continually<br />Cloud storage services allow us to buy just what we need and can react instantly to new capacity demands<br />
  6. 6. Cloud Offers Better Access at Lower Cost<br />6<br />SAN<br />NAS<br />Cost<br />Reduce Cost<br />VTL<br />Tape<br />Increase Accessibility<br />Accessibility<br />
  7. 7. Data Types Suitable for Cloud Storage<br />7<br />
  8. 8. Public Cloud Storage Economics<br />Just-in-Time Provisioning<br />Plan/buy for usage and not for peak capacity<br />Fully Managed Storage<br />Managed GB = Power, space, cabling, racks, monitoring, software, hardware, migration to new media… all included<br />Enterprise Purchasing and Pricing Model<br />Flat, bundled price starts at $0.25/GB/month, $3K/TB/year<br />Enterprise sales, engineering, and support staff<br />Consulting and strategy available<br />8<br />
  9. 9. Enterprise Cloud Storage: Why Not?<br />9<br />
  10. 10. Security & Reliability<br />No System is Perfect (including yours)<br />What to look for<br />Security audit (by a respected firm or customer)<br />SAS 70 (especially Type 2)<br />Customizable SLA (with remedies)<br />Transparency<br />Encryption (but who holds the keys?)<br />
  11. 11. Encryption for Cloud Storage<br />Where should encryption live?<br />(and who holds the keys?)<br />
  12. 12. Performance<br />Cloud storage is not for all data<br />But it’s for a lot of data!<br />Cloud-appropriate data:<br />File-based, unstructured<br />Non mission-critical<br />Value in keeping it accessible<br />Requirement to be outside the firewall<br />Multi-user, multi-site<br />Rarely written, frequently read<br />
  13. 13. Ingestion<br />Loading initial data can derail even the best cloud use cases<br />Bandwidth is sized to daily requirements<br />Initial data loading often requires an alternate path <br />Can you ship tapes? Disk arrays?<br />Who manages? Who pays?<br />
  14. 14. Implementation<br />APIs Aren’t “Simple” to Integrate<br />What to look for<br />Robust integrated functionality in applications<br />Solutions & integration services<br />Enterprise support<br />Standard storage protocol support<br />
  15. 15. Paths to the Cloud<br />
  16. 16. Economics<br />TCO is More Than Just $/GB<br />What to look at<br />Infrastructure costs<br />Connectivity/network costs<br />Security fees<br />Hardware utilization<br />System complexity<br />System management <br />
  17. 17. Use Case: Protect Data Off-Site<br />Data must be protected off-site…<br />Local outages and small-scale data losses are frequent<br />Regulations and standards call for off-site storage<br />IT responded by…<br />Shipping backup tapes<br />Using storage replication features<br />But…<br />Is it really secure?<br />Can you bear the cost and effort for replication?<br />Do backup tape-based solutions even work?<br />
  18. 18. Offsite Data Protection ASU/NASA Case Study<br />Images transmitted from moon via satellite<br />3 copies required (2 local 1 offsite)<br />Current offsite tape solution difficult to managed and scale <br />18<br />Data Receiving Servers<br />Expensive<br /><ul><li> labor intensive

  21. 21. only used for 1 copy</li></ul>Image Processing Servers<br />
  22. 22. Optimized management of tertiary data<br />Gained accessibility, security, and integrity<br />19<br />Data Receiving Servers<br />Economical<br /><ul><li> 40% cost reduction</li></ul>Cloud Gateway<br />API<br />Secure<br /><ul><li> monitored transfer

  24. 24. can replicate instantly</li></ul>Offsite Data Protection ASU/NASA Case Study<br />
  25. 25. Use Case: Tiered Storage<br />Storage capacity just keeps expanding…<br />Larger files + More files = Growing volume of data<br />IT responded by…<br />Consolidating on SAN and NAS<br />Tiered storage concepts<br />HSM and ILM<br />But…<br />Storage systems getting more complex and expensive<br />Management effort keeps growing<br />Cost savings aren’t materializing<br />20<br />
  26. 26. Fulfilling The Promise of Tiered Storage<br />Tiered disk storage has not yet lived up to its promise<br />Small cost and performance differential between FC and SATA disk<br />TCO is very close<br />SSD gives extreme performance at high cost<br />Cloud storage gives massive capacity at low cost<br />Tiered Storage<br />Performance and Cost<br />Capacity<br />21<br />Tiered Storage<br />SSD<br />FC<br />Disk<br />SATA<br />Cloud<br />

  38. 38. Use Case: Scalable Collaboration<br />Companies are going global<br />Need to distribute data between sites and organizations<br />New applications need programmable storage<br />More rich media, massive data volumes<br />Conventional systems don’t work<br />SAN and NAS don’t work well over wide area networks<br />Relational databases don’t scale to huge files, datasets<br />Lack of APIs, granular data controls<br />Everything is firewalled off anyway!<br />24<br />
