Born Again
“ If you were born before 1975 you’d call this a mainframe. If you were born after, you’d call it the Cloud. Let’s call it a giant computer.” - Paul Herrod, CTO EMC
Linux Strengths• (Potential) cost of zero
•Reliable,, known quantity “at scale,”
•Transparent
•Mature IT Management tooling
•Virtualization
•Existing, Linux applications
"We use [Linux] because it performs well on inexpensive, commodity hardware. That continues to be true and that continues to be a reason we use it."-- Anthony Golia, Executive Director of Enterprise Computing, Morgan Stanley
Linux Weaknesses
•Focus on the kernel, not apps and UX
•Perceptions and FUD
•Virtualization Fragmentation
Some Recommendations •Enforce Simplicity
•Start With AWS or Virtualisation
•Adopt integrated dev/ops
•Choose tech that supports on or off premise deployment
•Start Small
•Workload Triage
Conclusions
•Market still in Flux
•Cloud is not a product
•Think ahead: new business models
•Beware the Permission-based Web
