Room For Improvement

Apptio Cloudability needs to simplify interfaces, improve metrics, automate processes, and enhance integration for better user optimization and efficiency.
CAST AI needs improved documentation, user interface, reporting, cost insights, customization, integration, and analytics for larger organizations.
I've found that Groups is basically unusable because if it can't be used everywhere, you would have to run both group-based access control and direct user-based access control at the same time, which doesn't make any sense.
Cloud Ops Lead at a tech vendor with 10,001+ employees
I believe that automating all manual processes in Cloudability would be beneficial, providing a proactive prescriptive analysis on what needs to be done to lower costs.
Enterprise Data Architect at LTIMindtree
It would be beneficial if we could use resource tags to provide more fine-grained visibility.
Digital Marketing, Marketing Technology & Analytics Architect at a manufacturing company with 10,001+ employees
There are many pros here, including easy onboarding, simple deployment, and excellent Kubernetes visibility, strong spot instance automation, and automated right-sizing.
Sr.Devops engineer at Scaler
More detailed documentation and deeper visibility into certain optimization decisions would also be helpful.

To improve CAST AI, I would like to see more granular reporting, deeper cost allocation insights, and additional customization options for optimization policies.

Setup Cost

Apptio Cloudability offers comprehensive features with annual usage-based pricing, ideal for large organizations despite higher costs.
CAST AI offers usage-based pricing with minimal setup costs, providing transparent, value-driven pricing and licensing for enterprises.
Compared to the rest of the industry, they may be a little more expensive than some other FinOps tools.

Valuable Features

Apptio Cloudability optimizes AWS costs with features like Reserved Instance Planner, customized dashboards, extensive reporting, and seamless AWS integration.
CAST AI optimizes Kubernetes with automation and cost-saving features, reportedly saving organizations 20-30% on cloud expenses.
The forecasting feature has helped me understand how the resources are utilized and how the cost is burned, and then I use it to make changes to keep the cost in control.
Digital Marketing, Marketing Technology & Analytics Architect at a manufacturing company with 10,001+ employees
The Views feature is also beneficial because lots of teams may use Cloudability within an organization, allowing users to segregate data to particular Views so they are only looking at what's relevant to them.
Cloud Ops Lead at a tech vendor with 10,001+ employees
I find the reports to be extensive and elaborate, and I get whatever information I require.

Featured Reviews

reviewer2795433 - PeerSpot reviewer
Cloud Ops Lead at a tech vendor with 10,001+ employees
Gained multi-cloud cost visibility and have optimized spend with detailed reports and rightsizing
The IAM feature is something that we struggle with using. IBM, the company that runs Cloudability, released the Groups feature back in the summer of 2025. While Groups can be used in some parts of the tool, it can't be used across the entire tool. I've found that Groups is basically unusable because if it can't be used everywhere, you would have to run both group-based access control and direct user-based access control at the same time, which doesn't make any sense. The Groups feature has improved over time, but it's still not something we feel we can use on an everyday basis, so the IAM section remains an issue right now. Most of the tool is very well-functioning and developed, and that's the only real improvement area that we've seen.
DeepakReddy - PeerSpot reviewer

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.
