Identifies and eliminates overprovisioning of expensive resources like storage, highly scalable and offers performance
I like the overall product because I can select what monitoring should be enabled and whatnot. In our case, we really focus on performance because it's clear that the price is related to most performance setups. So the more performance, the more expensive. So we look into the performance that the customer needs, and then based upon that feedback from the remote control, we change the parameters. And even the end user will not notice it is not using it, so we just make money without any impact on the end users.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The price is reasonable, considering the value it delivers."
"I mostly like the dashboards."
"It offers a detailed examination of your cluster, including the types of instances utilized, allocated CPU and RAM, and resource distribution for specific applications."
"My compute costs have reduced, capacity and production output have increased, and my overhead for maintaining custom scripts or doing some of the tasks manually has been saved."
"Spot has positively impacted our organization by automating cloud resource management, which has significantly cut costs and improved efficiency."
"The solution helps us to manage and scale automatically whenever there is a limit to the increase in the application workflow."
"Cost saving is the main benefit, and the manual effort required for reviewing and purchasing savings plans and other RIs is something we do not have to manage manually now, as we get automatic suggestions from Spot."
"The solution offers both block access and file access, making it a nice solution for customers."
 

Cons

"The integration with other solutions could be improved."
"Faster monitoring could potentially improve overall stability in the production environment."
"There is a significant potential for enhancing it through the incorporation of advanced technologies like AI and generative AI."
"The solution doesn't have support from OCI, and it should start working to onboard OCI."
"I have not seen a return on investment yet."
"There are no particular areas for improvement I can identify."
 

Pricing and Cost Advice

"The cost is cheap. Kubecost has an open-source core."
"The cost of the tool may seem nominal compared to the potential savings in infrastructure expenses."
"The real savings come from using Kubecost features like autoscaling and serverless functions to optimize your resource usage. If you treat it like a data center migration without fine-tuning, it might cost more."
