Valuable Features

CoreStack enhances multi-cloud cost efficiency, visibility, compliance, and governance, improving operations, customer satisfaction, and resource savings.

Spot by Flexera offers cost optimization, Kubernetes management, and security compliance with intelligent autoscaling, AWS integration, and AI-driven insights.

The single pane of glass for multi-cloud cost optimization helps me day-to-day by bringing a lot of operational excellence; it saves a lot of time because rather than going to each and every account or multi-cloud portal, which takes a lot of time, having everything on a single pane of glass increases efficiency, delivers results in less time, and provides clear reporting that can be shared with the customer in PDF or CSV formats.

MandeepSingh4

The fact that it can mix dozens of instance families dynamically is something which the AWS native autoscalers simply cannot do.

Karan Saini

Dev Ops Engineer at a construction company with 11-50 employees

Spot helps us detect such changes within AWS at least one hour prior, allowing us to have a mitigation plan in place and host other servers within the same setup to avoid impacting the application.

Featured Reviews

Manmohan Rao

Associate Vice President at Hitachi Systems India Private Limited

Cost reports have driven accurate AWS workload optimization and continue to guide savings

I can suggest improvements for CoreStack, especially regarding reporting periods. I noticed that some of the cost optimization reports generated potential savings while considering systems that have only maximum utilization of 1% or 2%. The recommendations made in CoreStack to delete a machine have the potential to generate major cost savings, but such machines should not be listed for deletion if they have maximum CPU utilization of 1%. I have concerns about needed improvements primarily regarding AWS. If a customer is running ten virtual machines and one machine has a maximum of 1% utilization, it is considered as an idle instance in the report, which completely ignores that particular machine. This should not be the approach.

Karan Saini

Dev Ops Engineer at a construction company with 11-50 employees

Intelligent autoscaling has cut compute costs and now manages ephemeral workloads efficiently

I think overall Spot is quite good. The UI is powerful, but it can feel a bit dense for some new users. More guided onboarding would help teams adopt advanced features faster, and deeper insights into Kubernetes resource usage would be beneficial. Overall, it is a really good platform that is quite mature and stable. I chose a rating of nine because it may sometimes be a bit overwhelming for newcomers, and there are also a few areas in which the EKS Kubernetes level granularity is a little missing. Overall, I think Spot is a really good and stable tool.
