Transcript

  • 1. Cloud Computing Primer: Steps for using the Cloud in Your Museum Ari Davidow – jwa.org Charles Moad – imamuseum.org Robert Stein - imamuseum.org
  • 2. wikipedia on cloud computing via wordle.net
  • 3. CLOUD COMPUTING CLOUD APPLICATIONS UTILITY COMPUTING
  • 4. Cloud Applications ... eliminate the need to install and run the application on the customer's own computer, thus alleviating the burden of software maintenance, ongoing operation, and support.
  • 5. Cloud Applications
  • 6. Utility Computing … a style of computing where scalable and elastic IT-related capabilities are provided as a service to external customers using Internet technologies. 
  • 7. Utility Computing
  • 8. Buzz Worthy Search Trends for “cloud computing” Via Google Search Trends
  • 9. Source “Cloud Computing Gains in Currency”, Pew Research, May 2008 http://pewresearch.org/pubs/948/cloud-computing-gains-in-currency 69% of Americans use cloud computing services
  • 10. Gartner’s Hype Cycle for 2009 image courtesy of gartner.com
  • 11. 21% of companies are piloting SaaS applications up from 18% last year – Forrester, Feb 2009
  • 12. In Forrester’s List of the Top 15 Technology Trends
  • 13. State of Cloud Computing
    • Forrester feels that cloud computing is one of the  Top 15 Technology Trends  and that it warrants investment now so you can gain the experience necessary to take advantage of it in its many forms to transform your organization into a more efficient and responsive service provider to the business
      • - Forrester, October 13, 2009,
    “ http://blogs.forrester.com/it_infrastructure/2009/10/cloud-computing-belongs-on-your-3year-roadmap.html
  • 14. Gartner’s #1 Strategic Technology Area for 2010
  • 15. State of Cloud Computing Cloud computing isn't going to be vapor much longer… It's complicated, poses security risks, and computing technology companies are latching onto the buzzword in droves, but the phenomenon should be taken seriously… -Gartner - October 20,2009 http://news.cnet.com/8301-30685_3-10378782-264.html “
  • 16. Concerns about SaaS
  • 17. Pros of Cloud Computing
    • Fast Deployment
    • Lower cost / No Capital Expense
    • Reduced IT maintenance
    • Elastic and Unlimited Scalability
    • Energy Efficiency
    • Reliability (Service & Data)
    • Better Resource Utilization
  • 18. Cons of Cloud Computing
    • Information Security
    • Physical Security
    • Long Term Offline Storage
    • Bandwidth Bottleneck
    • Potential Vendor Lock-in
    • Lack of control during downtime
  • 19. Amazon Web Services (AWS) Overview Amazon Web Services (AWS) Infrastructure Services Elastic Compute Cloud (EC2) Simple Storage Service (S3) SimpleDB Simple Queue Service (SQS) Elastic Block Store (EBS) Elastic MapReduce CloudFront Content Delivery Network Relational Database Service (RDS) Virtual Private Cloud
  • 20. How to make choices about Cloud Computing
    • What sort of security requirements fit your data?
    • How granular is the information you’re working with? (documents, images, video?)
    • Where are your likely performance bottlenecks? (compute, bandwith, latency)
    • What is your IT staff like? (small but flexible, large)
  • 21. Jungle Disk
  • 22. Jungle Disk - $20 / www.jungledisk.com
  • 23. Requires
    • Amazon S3 account, and the requisite keys:
    • JungleDisk software installed
  • 24. Usage
    • Backs up at scheduled times
    • Can back up more than one machine, or to more than one backup set
    • The first backup may take days – or longer. No problem. The software gracefully goes to sleep when you shut down or hibernate; resumes upon waking until done
    • Can retrieve files using drag/drop interface using pull-down to set the date of the view from which you wish to retrieve (i.e., let me see the files as they were on July 7, 2008).
    • Retrieves files gracefully and quickly
  • 25. Converse Example
  • 26. IMA’s SAN
    • IMA Purchased 32TB of EMC SAN in 2006
      • 16TB local and 16TB at an offsite co-location facility
    • Due to growth in Collection Photography, Video, and Conservation Imagery that space is all but full!
  • 27. IMA’s SAN
    • Benchmark Growth Rate
      • Total Current Size – Initial Size / 36 months
      • Ballpark Rate of 142 GB/month
    • Yielding 13.9TB estimated in the next 4 years
  • 28. IMA’s SAN
    • 16TB Onsite + 14TB AWS = $164,544
    • 16TB Onsite + 16TB Colo = $94,200
  • 29. Hidden Costs
    • DS3+Colo = $96,000 (3 yr commitment)
    • Maintenance and administration of servers (2 FTE’s)
    • As replicated backup for super large file-systems time for restore would be huge!
  • 30. AWS Tools
  • 31. Elasticfox & S3Fox
  • 32. EC2 Console
  • 33. Moving Drupal to the Cloud: Step by step
  • 34. Introducing the EC2 Console
  • 35. Creating a Key Pair
  • 36. Creating a Security Group
  • 37. Selecting a Starter AMI
  • 38. Launching an AMI
  • 39. Connecting to Your EC2 Instance
  • 40. Creating an EBS Volume
  • 41. Configuring Apache and MySQL
  • 42. Setting up Drupal
  • 43. Bundling an AMI
  • 44. ami-764bab1f
  • 45. Fedora for DAM
  • 46. Fedora as a testbed on AWS Project Goals: External vendor to create least-possible Fedora instance to enable preservation work
  • 47. Summary
    • Create on AWS and hand over instance when done
      • When dev site is completed, create “Amazon Machine Instance” and check into Subversion
      • Document installation and everything else in wiki
      • We create new instance from checked-out AMI
      • This ensures that we have maintainable code that we can get up and running, before developer moves on
  • 48. What we did
    • Original server created using developer’s favorite Linux
    • We use CentOS, so when we checked out the AMI, we recreated running under CentOS, bundled new AMI to S3
    • AMIs can be independent of the underlying OS
  • 49. Bugs
    • Our repository, which consists of lots of very large files, uses a unix filesystem called XFS
    • XFS supports very large volumes better the usual filesystem, and supports real-time snapshotting of huge file-systems
    • AWS updated CentOS and broke XFS
    • We (actually, our webmaster) rebuilt kernel to work around AWS CentOS bug
  • 50. Other Gotchas
    • An EC2 instance doesn’t preserve state
      • When you restart, it restarts from scratch
      • All config changes, anything else that was done and saved to the previous instance is gone
    • So, you use EBS, which acts something like a network drive (think NetApps)
      • You purchase blocks of EBS space at a time, but it is cheaper than S3 per GB/Month
      • This is different from S3 storage where you pay only for what you consume
  • 51. AMIs
    • Amazon Machine Instance
    • Sort of like a “ghost”ed server image
    • Amazon (and others) provide lots of AMIs to work with
      • AMIs can be public or private
      • You can use different AMIs on different servers in your AWS setup
      • “ bundling” is the AWS term for saving that AMI with your modifications for future use.
      • We store AMIs on S3; could also use EBS
  • 52.  
  • 53. Lessons Learned
    • We liked AWS so much, and saved so much money, that we have now moved all of our web services to AWS.
    • Our website used to cost us $1200/mo. It has added about $450/mo to what we already pay for the Fedora instance – about $900/mo total.
