Featured Reviews

DeepakReddy - PeerSpot reviewer
Sr.Devops engineer at Scaler
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.

Manages hybrid infrastructure seamlessly with flexible cluster scaling and comprehensive oversight
The most important aspect of Nutanix Cloud Manager (NCM) is that it helps us manage the infrastructure as a hyperconverged infrastructure in HCI mode. If I have different physical servers, I can map them into a cluster and manage the storage together. It provides flexibility to make use of storage in a clustered format instead of using it in an individual storage endpoint. We have the flexibility to have Nutanix-based licensing based on the core model, instead of having a specific cost on the cluster. The costing on a core model gives customers flexibility to add multiple cores to a single physical host and adjust the infrastructure accordingly, and we can scale up the cluster as needed. While other cloud providers, AWS or Azure, are mostly into cloud-based solutions, and Azure has introduced Azure Stack HCI for managing on-premises infrastructure, Nutanix Cloud Manager (NCM) provides flexibility from day one. We can manage both on-premises and Azure solutions using a single pane of glass, eliminating the need to navigate different windows or screens. It provides a comprehensive view of the infrastructure and highlights specific areas through alerts, giving us good visibility of infrastructure conditions.
