Automated cost controls have cut cloud waste and free our team to focus on new projects
CAST AI can be improved in that automation policies require careful tuning. Sometimes it can be confusing for non-technical people or managers who are not familiar with technical details. However, it is good for technical people who are already into DevOps or cloud engineering. Spot strategies may need adjustment for sensitive workloads. The reporting and UI part can be somewhat better. Technical support can also be improved. Documentation is somewhat unclear sometimes, but not everywhere. There are many pros here, including easy onboarding, simple deployment, and excellent Kubernetes visibility, strong spot instance automation, and automated right-sizing. These features are very good for our organization because they reduce a lot of cost and reduce a lot of manual effort. However, some things can be improved, such as automation policies that require careful tuning and may need somewhat more help. Spot strategies can be improved, and some UI and documentation can also be improved.

Simple to set up with helpful for cost management and good reliability
The only issue I faced was a while ago. My card was debited, or rather it was showing as debited when in actuality, it did not debit my card. After six months, they came back with back billing. Somebody should have verified the billing and immediately informed us. So yeah, However, six months is too late to identify such fault sightings. When I want to analyze the information, it would be better, since Google knows what I have used, to only show those items for analysis purposes. Especially when I look at a previous month's billing or usage across services. It's better to show the services which are used, not everything.
