    Looks like the slideshow is truncated at 36 slides? All of the content after 'What is fabric' is missing.

    Very interesting ppt. The research indicated PPT only contains 30% of information; therefore the 70% valuable information comes from the presenter himself/herself. soEZLecturing.com provides you a chance to record your voice with your PowerPoint presentation and upload to the website. It can share with more readers and also promote your presentation more effectively on soEZLecturing.com.

Plone in the Cloud - an on-demand CMS hosted on Amazon EC2 - Presentation Transcript

  1. Plone in the Cloud A CMS hosted on Amazon EC2 Nate Aune (Jazkarta.com) PyCon 2009 Chicago, IL Tuesday, April 7, 2009 1
  2. • President of Jazkarta (based in Boston) • 3 Full-time and 10 freelance developers • Python-based open source web applications • Members of core Plone framework team • Member of the Plone Foundation Board Tuesday, April 7, 2009 2
  3. In the next 30 min... • Amazon Web Services (AWS) • AWS with Python • Plone with AWS • Tools for launching & remote deployment • Challenges of using AWS • Monitoring and maintaining EC2 instances Tuesday, April 7, 2009 3
  4. What is Amazon Web Services? Tuesday, April 7, 2009 4
  5. What is Amazon Web Services? • Suite of elastic IT infrastructure services • Requisition computing power and storage • Run any application you want on any OS Tuesday, April 7, 2009 5
  6. Benefits of AWS • Metered pricing (per hour / per GB) • no large up-front capital investments • only pay for what you use • Scaleable hosting architecture • Redundancy for high availability Tuesday, April 7, 2009 6
  7. AWS Architecture • EC2 = Elastic Computing Cloud • S3 = Simple Storage Solution • EBS = Elastic Block Storage • Elastic IP = Static IP addresses Tuesday, April 7, 2009 7
  8. Elastic Computing Cloud (EC2) amazon.com/ec2 • Use an existing AMI (Amazon Machine Image) to launch a new instance • Or create your own AMIs (even paid ones) • Attach EBS volumes to your EC2 instance Tuesday, April 7, 2009 8
  9. Elastic Block Storage (EBS) Tuesday, April 7, 2009 9
  10. So how does Python play into all this? Tuesday, April 7, 2009 10
  11. Enter Boto Tuesday, April 7, 2009 11
  12. What is Boto? • Python package that provides interfaces to Amazon Web Services • Thanks to author Mitch Garnaat! • Boto supports: • S3 via the REST API • EC2 via the Query API • and more... Tuesday, April 7, 2009 12
  13. Install Boto & Bototools $ sudo easy_install boto $ svn co http://bototools.googlecode.com/svn/trunk/ bototools $ cd bototools $ sudo python setup.py install $ sudo python ./src/bototools/postinstall.py -p /usr/local/bin • This will put these commands in /usr/local/bin: • ec2start, ec2stop, ec2ip, ec2ls, ec2img • s3ls, s3rm, s3cp Tuesday, April 7, 2009 13
  14. Using Bototools • Set these environment variables: • AWS_ACCESS_KEY • AWS_SECRET_ACCESS_KEY • EC2_SSH_KEY • Can also put in ~/.boto or /etc/boto.cfg Tuesday, April 7, 2009 14
  15. Find an AMI • We will use the Ubuntu 8.10 Intrepid (32-bit) from Alestic.com - ami-7cfd1a15 • More can be found at: http://developer.amazonwebservices.com/connect/kbcategory.jspa?categoryID=171 Tuesday, April 7, 2009 15
  16. Launch an instance $ ec2start -a ami-7cfd1a15 -k gsg-keypair Reservation:r-0f26a666 [Instance:i-8e3154e7] $ ec2ls Reservation r-0f26a666 i-8e3154e7 pending None 2009-03-25T01:49:24.000Z ...wait... $ ec2ls Reservation r-0f26a666 i-8e3154e7 running None 2009-03-25T01:49:24.000Z ec2-174-129-238-8.compute-1.amazonaws.com Tuesday, April 7, 2009 16
  17. Associate a static IP $ ec2ip -g Address:174.129.238.8 $ ec2ip -l 174.129.238.8 -> $ ec2ip -a 174.129.238.8 i-8e3154e7 True $ ec2ip -l 174.129.238.8 -> i-8e3154e7 • Note: once you assign a static IP, you won't be able to access the machine using the original IP. Tuesday, April 7, 2009 17
  18. Log in $ ec2ls Reservation r-0f26a666 i-8e3154e7 running None 2009-03-25T01:49:24.000Z ec2-174-129-238-8.compute-1.amazonaws.com $ ssh -i ~/id_rsa-gsg-keypair root@ec2-174-129-238-8.compute-1.amazonaws.com Linux domU-12-31-39-00-E5-14 2.6.21.7-2.fc8xen #1 SMP Fri Feb 15 12:39:36 EST 2008 i686 root@domU-12-31-39-00-E5-14:~# • Time to play! Tuesday, April 7, 2009 18
  19. Stop the instance $ ec2stop i-8e3154e7 Stopping ['i-8e3154e7'] $ ec2ls Reservation r-0f26a666 i-8e3154e7 terminated None 2009-03-25T01:49:24.000Z • Be sure to stop the instance or you will be charged! Tuesday, April 7, 2009 19
  20. Use the AWS Console Tuesday, April 7, 2009 20
  21. Or use ElasticFox • Firefox extension to start/stop EC2 instances, assign IPs, associate EBS volumes and create keypairs. http://developer.amazonwebservices.com/connect/entry.jspa?externalID=609&categoryID=88 Tuesday, April 7, 2009 21
  22. Case study Plone on EC2 Tuesday, April 7, 2009 22
  23. What is Plone? • Open source content management system (CMS) • Built on top of Zope • Written in Python • Large international community • Used by Oxfam, NASA, Novell, Akamai, FSF, etc. • more listed at http://plone.net/sites Tuesday, April 7, 2009 23
  24. Why Plone on EC2? + • Too few Zope hosting providers • Avoid renting rackspace in co-lo • Flexible and scalable architecture • Complete control of servers Tuesday, April 7, 2009 24
  25. What is PondCMS? PondCMS = Plone On Demand • Hosted and supported version of Plone • Eliminate the complexities of hosting • Turnkey - automated and repeatable • Bundled with certified add-ons www.jazkarta.com/pondcms Tuesday, April 7, 2009 25
