• Fast disk is “ephemeral”

• Multiple data centers are everywhere

• Servers and storage are infiniteAmazon: regions & availability zones


Era of Infrastructure as Code

!18

• The cloud is “API infected”

• Infrastructure as Code is in the DNA of the cloud

• Chef, Puppet, AWS CloudFormation, AWS OpsWorks, CloudInit...

For DEV: Evolution or Revolution?

!20

• Infrastructure services are still built by the OPS team ⇒ not new

• But the mindset of OPS teams can change to “as a Service”

• Opportunity to embrace Infrastructure as Code

Evolution Revolution


IaaS is Just a Transition to PaaS

• IaaS platforms are adding services

• 30+ services on Amazon AWS

• Running your own MySQL on the cloud???

• Go Go Go!

• Great source of innovation and opportunity for improvement

• Not a silver bullet to adopt the “as a Service” culture

• Don’t underestimate the learning curve and the difference of skills

!22


How.toIaaS()

• Choose a green field infrastructure

• With the Infrastructure as Code team (Chef, Puppet, ...)

• Innovate, adapt your procedures and technical solutions
