PaaS

terraform – infrastructure allocation

• multiple providers
• simple dsl
• state per region

packer – ami baking

• reduce launch time
• use current ansible roles

PaaS

ansible – deployment tool?

• prepare marathon json before launch

ansible – platform configuration

• zookeeper, mesos, consul, weave...
• get state dynamically from ec2

PaaS

missing parts

mesos

• scale up/down
• share dev/production agent instances?

vault – secretes management

• secret storaga
• key rolling
• audit backend
