Challenges to better streamline development
About Cloud Automations...
- Cloud Automation is a really powerful tool but can be heavily destructive if not used properly...
- As of today we needed to have a DevOps engineer dealing with infrastructure changes due to the knowledge required
What if the infrastructure change is ...
- Just a threshold update for an alarm ?
- An additional networking link between two services ?
- Trivial and can be safely done by Developers ?
Atlantis
Introducing Atlantis
Bring the benefits of code review to your operations workflow.
Developers can submit infrastructure code changes with DevOps approval.
