Info

This document talks about:

  • More customers are deploying Iguana on the cloud and they are trying to figure whether Iguana can support container architecture

  • Containers offer increased portability (quickly spin up and down containers in any environment) and require less overhead than virtual machines (enables support for multiple applications on a single OS).

  • Even though there is no official Iguana container solution, here are some sample configurations and design that could get you started

Understand Container and Docker
