Optimized cloud workloads and cut costs while highlighting needs for clearer predictive insights
CAST AI is a useful platform for automating Kubernetes infrastructure and reducing cloud costs. However, I see improvement needed in cost visibility and reporting. There is a dashboard, but it doesn't showcase predictive scaling. A predictive scaling feature could be added where I can see more transparency around automated infrastructure decisions, especially when nodes and workloads are being replaced. There is a predictive cost involved, and that should be readily seen by CAST AI's dashboard so I could make better infrastructure choices and auto-scale in a better way. I would position myself to focus on better cost reporting and smarter predictive scaling as an added feature which could be a selling point for CAST AI. Additionally, there is the team saving concept where there could be visibility for different teams. Regarding understanding CAST AI's use case, I attended AWS re:Invent, where they sent out a demo to use CAST AI and other resources. I downloaded the necessary features and undertook the course to understand most of CAST AI's features. Although there was a demo and educational materials, CAST AI's use case needs to be more user-friendly for new users to understand what CAST AI is, what it is truly useful for, and where it exactly stands. The engagement with new users was limited. I could watch videos and have understanding about Kubernetes and where I could use CAST AI, but what about a person who would not know about Kubernetes or any scaling features? If a new organization wants to know about CAST AI and its use cases, they might face feasibility issues in understanding CAST AI and its applications. If there is a handbook, playbook, or basic guide showing where CAST AI can work well for them, that would help a lot for new users of CAST AI. I have mentioned most of the improvements I identified.

Multi-cloud costs have become transparent and teams gain persona-based insights to optimize spend
CloudZero is a multi-cloud cost management solution for enterprise organizations who want to view their cloud spend in a single dashboard with appropriate information and identify cost anomalies in a faster manner. The best features CloudZero offers include persona-based dashboards, meaningful data insights to optimize cloud spend, and telemetry data and integrations with other cloud platforms, along with email-based proactive cost anomaly alerts. CloudZero offers a single pane of dashboard to understand cloud cost visibility for a multi-cloud infrastructure, and we were able to drill down into unit economics to understand the unit level cost in each cloud platform. The governance and security are excellent, allowing us to create and assign permissions based on each persona, so the security features are outstanding. The accuracy and reliability are excellent by using CloudZero AI features, and we were able to get more meaningful data insights for optimizing cloud spend. The features are excellent and we were able to add the AI feature in CloudZero to get more valuable cost optimization insights. Using CloudZero dashboards, every team is able to understand their cloud spend by cloud platform and it helps to detect cost anomalies before there is a cloud cost spike.
