Cloud cost management gets even trickier in cloud-native environments. This is why the market is brimming with Kubernetes-specific solutions such as Kubecost. Alternatives to this tool are popping up all over the place, too.  

Finding the right Kubernetes cost management solution can be challenging since different suppliers offer a variety of features, cloud pricing methods, and use cases. Our team examined cloud cost management technologies to help you keep track of your cloud spending. 

All of the options listed here can help organizations optimize their cloud bills and expedite their cloud cost monitoring and reporting procedures. However, our research indicates that only solutions that go beyond cost monitoring and reporting and provide automatic cloud cost optimization may make a significant difference.

Kubecost alternatives: The key limitations of Kubecost

Before we move on to examine the Kubecost alternatives, let’s take a look at why teams are looking beyond this solution. 

Kubecost provides insights on Kubernetes cost allocation, monitoring, and alerts, as well as cost breakdown tools that are versatile and customized. Its detailed insights and cost reporting features make it an excellent pick for teams seeking to manage their multi-cloud infrastructure. 

However, since it lacks automated Kubernetes cost optimization, you’ll have to make the necessary modifications manually. This includes additional costs that don’t guarantee a good ROI. 

That’s why it’s worth focusing on Kubecost alternatives that offer some degree of automation in your selection process.

6 Kubecost alternatives you should consider

1. CAST AI – automated Kubernetes cost management and optimization

CAST AI is a fully-automated platform that analyzes, monitors, and optimizes Kubernetes applications. Its main competitive advantage is automation, offering capabilities like rightsizing, instance selection, autoscaling, spot instance use, and resource decommissioning.

This isn’t to say that CAST AI doesn’t have cost monitoring features. The platform provides users with a wealth of cost information by categorizing cloud expenses into project, cluster, namespace, and deployment levels. Teams may track costs down to individual microservices and get a comprehensive estimate. 

CAST AI selects ideal compute resources for application requirements while saving costs, thanks to automation. When a cluster requires additional nodes, the automation engine chooses the best-performing instances at the lowest cost, assisting teams in avoiding overprovisioning. 

CAST AI also comes with a free security report. You may scan your cluster against the CIS benchmark, the NSA-CISA framework, and other container security best practices to find vulnerabilities or misconfigurations, and it will automatically prioritize them in a matter of minutes.

CAST AI advantages

  • CAST AI is made for Kubernetes teams and addresses challenges that are specific to cloud-native technologies.
  • It provides a cost reporting module that breaks down cloud charges by project, cluster, namespace, and deployment. A team may track costs down to individual microservices and then get a full estimate of cluster costs. 
  • Using AI, the platform selects the best resources for your application’s needs while lowering expenses using autoscaling and rightsizing capabilities. 
  • When a cluster requires more nodes, the automation engine chooses the best-performing instances at the lowest possible cost. This allows teams to avoid overprovisioning and achieve high resource utilization. 
  • CAST AI’s autoscaling settings help users save money. The platform calculates the ideal number of necessary pod instances and adjusts the replica count of pods. If there is no work to be done, it eliminates all nodes. 
  • CAST AI can also help you avoid paying for resources you don’t utilize by emptying nodes. To optimize savings, the method incorporates automated bin packing. 

CAST AI limitations

  • It only works with Kubernetes (EKS, AKS, and GKE).

Takeaway: CAST AI is ideal for companies seeking to cut cloud expenses without increasing engineer burden. Another ideal use for CAST AI is in teams that seek to automate time-consuming cost optimization processes like instance selection, rightsizing, or autoscaling.

It enables you to operate clusters on spot instances without provisioning or scaling instances. 

Spot by NetApp advantages

  • Spot by NetApp is a cloud cost management application that uses spot instance automation to reduce cloud expenses. Spot by NetApp splits cluster infrastructure expenses and provides information on each infrastructure tier. 
  • You may divide expenditures into namespaces and particular workloads inside each namespace, and you can further filter them by layer. Users get compute and storage expenses for each task.
  • Spot by NetApp data can be used to monitor application costs, execute chargebacks without substantial resource tagging, forecast future cloud expenditure, and modify resources on the fly based on suggestions from Spot by NetApp’s cloud cost management platform. 
  • The platform continuously analyzes workload usage and provides recommendations for manually changing resource needs by container and task. This allows for simpler high-level visualization and faster implementation without interfering with applications.
  • NetApp Spot detects unscheduled pods and scales infrastructure to guarantee that all of your pods have a place to run. 
  • Furthermore, Spot by NetApp prioritizes downscaling the least used nodes and eliminates them if all pods operating on them can be moved. 

Spot by NetApp limitations

  • The key point is that NetApp’s Spot decreases cloud expenses by focusing on spot instances. The tool recommends running workloads primarily on more spot instances, perhaps missing out on additional cloud cost optimization possibilities that might result in even greater savings.

Takeaway: organizations may benefit more from solutions that provide the same degree of automation but for more than simply spot instances, and are ideally capable of automatically assessing workload requirements and matching them with suitable cloud resources (such as CAST AI).
