OpenSource ToolChain for the Hybrid Cloud
Download as PDF, PPTX3 likes795 views
This document discusses assembling an open source tool chain for a hybrid cloud environment. It describes using Packer to build machine images for multiple platforms like AWS, VMware, and VirtualBox from a single blueprint. It also discusses using Vagrant and Ansible for automation, configuration management, and provisioning virtual machines across different cloud providers in a standardized way.
