The Benefits of Cloud StorageMay 19, 2009
Stephen Foskett, Director of Consulting, Nirvanix
Abstract
The demand for storage has increased, placing significant stress on "in house" storage infrastructures and costly overcapacity build-outs
Factoring in our current economic state and the pressures of power, space, capital expenditures, global performance, and availability issues, companies are faced with an exploding challenges and costs
Cloud storage platforms enable enterprises to cut costs and focus on more important aspects of business, but with many competitors in the marketplace it's hard for businesses to decide which option is best
This session will teach attendees about the uses of cloud storage within enterprise levels of deployment and shed some light on the current solutions available today

Top Storage Issues for IT
3
Storage Is Supposed To Be Getting Cheaper!
4
Disk cost is dropping rapidly
$250 buys: 1994: 2 GB 1999: 20 GB 2004: 200 GB 2009: 2000 GB
But enterprise storage costs keep rising!

Explosive Growth of Unstructured Data

User Generated Contentat work and home
Bigger Digital Shadows multiple versions and
formats
95% is unstructured

Conventional tiered storage has little impact
Tiered Storage: Where’s The Savings?
6
Offline:Tapes and
Trucks
Tape-Based Archives
High-end storage costs 4-8x as much as plain disk
“Low cost” enterprise storage delivers only 20%-
30% TCO reduction
Tape looks cheap, but data is inaccessible and costly to
bring back on line, so we only use it for archives
Online:“The Box”
Fibre Channel
ATA
RAM Cache
Storage arrays have a little RAM to accelerate disks
Rising cost and complexity of storage
Explosive growth of unstructured data
Tiered storage isn’t the solution
Need to do more than just lock data away

Companies Must Change Storage Strategy to Consolidate & Gain Efficiencies
Inflection Points – Move to the Cloud

Defining Cloud Storage
Storage is offered as a service with standard interfaces
Billing is usage based
Infrastructure is multi-tenant and scalable

Solid state performs much better but costs a lot – use it as a cache for slow disks
Most on-site data resides on accelerated ATA
Less-accessed primary data is moved to the cloud
Some data still needs high-performance FC disks
Archival data lives online in the connected cloud, too!

Need to Keep and Reuse - Media Example

Content is the core IP of media companies Protection of raw footage Digital preservation of historical
works
Increasing need to repackage, repurpose , distribute and monetize content
“Archive everything - we don’t always know what we will need”
Transition to file based workflows moves archive from dusty storage room to critical storage element

Enterprise Cloud Storage: Why Not?
Security & Reliability
No System is Perfect (including yours)
What to look for Security audit (by a respected firm or customer) SAS 70 (especially Type 2) Customizable SLA (with remedies) Transparency Encryption (but who holds the keys?)
Encryption for Cloud Storage
Where should encryption live?(and who holds the keys?)
Performance
Cloud Storage is not for all Data
But it’s for a lot of Data
Cloud-appropriate data: File-based, unstructured Non mission-critical Value in keeping it accessible Requirement to be outside the firewall Multi-user, multi-site Rarely written, frequently read
Ingestion
Loading initial data can derail even the best cloud use cases
Bandwidth is sized to daily requirements
Initial data loading often requires an
alternate path
Can you ship tapes? Disk arrays?
Who manages? Who pays?
Implementation
APIs Aren’t “Simple” to Integrate
What to look for Robust integrated functionality in applications Solutions & integration services Enterprise support Standard storage protocol support
Paths to the Cloud
Economics
TCO is More Than Just $/GB
What to look at Infrastructure costs Connectivity/network costs Security fees Hardware utilization System complexity System management
Barriers are Down: What Next?
Start with cloud proof-of-concept Match dataset with security & bandwidth needs Select a provider based on TCO Perform test & measure outcomes Secure multi-year agreements
