New Features: Storage Toolbox• It's all about persistence!• Primary Backup

• Uses local cloud persistence• Volumes snapshots preferred (i.e. EBS, Volumes)

• Secondary Backup• Uses remote cloud for redundancy• Useful in case of local cloud outage• LVM snapshot uploads to a Remote Object Store (i.e. Amazon S3, Azure

Storage, Google Cloud Storage, Rackspace CloudFiles)

• Built on our battle tested EBS Toolset

New Features: Built-In Firewall Support

# 20

New Features: Update ActionTo open a local port to all servers with a given tag use:

sys_firewall "Open 3306 to all appservers" do machine_tag "appserver:active=true" port 3306 enable true action :update end

This can be useful as a server is booting to open up access for multiple systems at once.

# 21

New Features: Update Request ActionTo request all servers with a given tag close a port to a given IP address

use: sys_firewall "Request all close port 8000" do machine_tag "loadbalancer:www=app" port 8000 enable false ip_addr node[:cloud][:private_ips][0] action :update_request end

This can be useful when decommissioning a running server that had previously requested ports opened.
