-------------------------------------------
Summary: Add "Removed" field and/or versioning and/or rollback on
Firewall/Nat/FB rules
Key: CLOUDSTACK-5919
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5919
Project: CloudStack
Issue Type: New Feature
Security Level: Public (Anyone can view this level - this is the default.)
Components: Network Controller
Affects Versions: 4.2.0
Reporter: Roeland Kuipers
Fix For: Future
To power of an IaaS cloud is that everything can be automated like network
changes. This comes with a huge risk in case of human error or malfunctioning
code.
For example a cookbook which contains a bug and instead of adding a rule
removes all fw/nat/lb rules.
Currently this means that if you cannot restore this from your cfg mgmt system
that you need to restore these rules from a database backup, which is a
somewhat lengthy and complex process.
A way to mitigate this risk is to add a removed field to the fw/nat/lb rules
tables. This seams common practice on a lot of CS tables. But not on these
specific tables. A nicer implementation would be to add a versioning system
behind these configurations.
This might look like a corner case but unfortunately this is real live
experience.
