A recorded rehersal of a talk on Cloud Computing and it's potential effects (good and bad) on Linux. The final version of this talk was given at the Linux Foundation Collaboration Summit on April 9th, 2009. For a write-up of the talk, see my entry over at PeopleOverprocess.com.

Cloud Computing and Linux

  1. 1. Cloud Computing Michael Coté, RedMonk Thursday, April 9, 2009 1
  2. 2. Expectations • Cloud computing now is like early SOA: it’s silly-putty • We’ll take a simple definition and go with it • How does “Linux” fit in? SWOT. Thursday, April 9, 2009 2
  3. 3. The 3 *aaS’s of Cloud Computing • SaaS, PaaS, and IaaS • There are many more *aaS’s • Applications, Middle-ware, servers * Christofer Hoff Thursday, April 9, 2009 3
  4. 4. Why Cloud Computing? Users Vendors • • Cost New business models • • Flexibility New features • • Elasticity/scalability Lower cost of ongoing maintenance? Thursday, April 9, 2009 4
  5. 5. Concerns • Hype-fed, Semantic Confusion - public vs. private • Retraining - multi-thread dev, dynamic ops • Ending up paying more - e.g., $20k on-prem vs. $150k off-prem • Lock-in • Legacy concrete • Virtualization turns out to be more important - “fog computing” Thursday, April 9, 2009 5
  6. 6. Things to point at • IaaS - Amazon EC2, S3, etc. • PaaS - Force.com, Microsoft Azure • Sun Cloud, 3Tera, Rackspace, & reborn hosters • Automation & provisioning people Thursday, April 9, 2009 6
  7. 7. Linux Strengths • Appealing for it’s (potential) cost of zero • Reliability, known quantity “at scale,” quot;We use [Linux] because it performs well on bredth inexpensive, commodity hardware. That continues to be true and that continues to be a reason we use it.quot; • -- Anthony Golia, Executive Director of Enterprise Malleable & Transparent Computing, Morgan Stanley • Easer for IT Management tooling • Virtualization • Existing, Linux-compatible applications Thursday, April 9, 2009 7
  8. 8. Linux Weaknesses • Focus on the OS level, not applications and usage • Weak connections to development platforms, with exceptions like LAMP • Virtualization & Automation Fragmentation • Susceptible to “bad citizens” Thursday, April 9, 2009 8
  9. 9. Linux Opportunity • OS for Cloud clients - Netbooks, RIAs, “mobile” • Model driven automation • Fragmented air-space - everyone wants a cloud, everyone wants Linux • Easy way to boot-strap into using Linux Thursday, April 9, 2009 9
  10. 10. Linux Threats • SaaS & PaaS means “the OS doesn’t matter” - cars with hoods that don’t open (past:VM & CLR) • Commercial vendors creating new closed source worlds - Apple • Cloud Distro Madness - QA & support matixes • Cloud consolidation & collapse - eggs in a basket Thursday, April 9, 2009 10
  11. 11. Conclusions • Worse case scenario: nothing changes • Best case scenario: many more Linux instances • Thinking ahead: transitioning “brown field” applications Thursday, April 9, 2009 11
