Often Hybrid Cloud is talked about in terms of migrating entire VMs. This is fraught with problems, and can be better acheived by using automation to move a VMs configuration instead of the entire VM.

P2V Your Technical Debt 
 VM Converter

Why the technical debt?

Failure to capture configurations • Manual Changes • Not Captured in a repeatable format • Changes poorly documented

Large cumbersome automation • Hard to use • Not Repeatable • Not Idemoptent • Not Convergent

Low perceived value of automation • Quicker to do it manually • Focuses on longer term results • Payback period for automation

Images are all I need • Golden Images • Build images to repeat configurations

Enter Hybrid Cloud

Magic Bits

Magic Bits

Problems • VMs are heavy • C2Cing your technical debt • Large management overhead • Doesn’t really realize the benefits of Cloud


Solutions • Configs lighter than VMs • Reduces moving data already in your Clouds • Can leverage things like SCM • Define once, run anywhere

Problems • Requires discipline • Doesn’t solve data issues • Requires upfront investment of time

The question isn’t: how do I get a server, defined by VM (or instance) into another Cloud to serve my application

The question is: how do I get a server, defined by a set of finite configurations, into another Cloud to serve my application

Some things I’ve seen work • Ignore legacy • Focus on Cloud first • Get development buy-in to change app stack • Build Composable, Data Driven Automation

Infrastructure as Code

TDD of Infrastructure Code • Test Driven Development • Verify before deployment • Reduce development time

Leverages Software Development Lifecycle • Infrastructure Code stored in Source Control • Who, What, When, Why, How

Repeatable and Reusable • Write once, Run anywhere • Cross Cloud, Cross Platform

Additional Requirements • API Based automation • Node based evaluation and execution • Declaritive DSL • Flexibility of real language
