A Guide To Kubernetes FinOps

According to CNCF, many organizations are rapidly moving towards cloud-native and open-source projects based on Kubernetes. However, many of them have reported a sudden increase in their Kubernetes-related spending within just 12 months! They have either overlooked their cloud spending or relied on their monthly estimates.

Are you also struggling to cost-optimize your Kubernetes infrastructure while ensuring optimal performance? If so, you’re not alone! Fortunately, there’s a solution: FinOps for Kubernetes. Whether you’re part of a team following FinOps practices or just getting started, it’s high time to utilize FinOps for cost allocation, resource optimization, and spending visibility across your Kubernetes Clusters! Let’s map your cloud utilization costs with FinOps for Kubernetes!

Understanding FinOps: What Is It and Why Does It Matter?

FinOps, short for Financial Operations, is a discipline that aims to align cloud spending with business objectives. It provides a framework and set of practices to help organizations optimize cloud costs while maintaining operational excellence. In the context of Kubernetes, FinOps becomes particularly crucial due to the dynamic and scalable nature of containerized workloads.

Looking At The Challenges Of Controlling Kubernetes Costs From A FinOps Angle:

With Kubernetes, businesses often face challenges related to cost visibility, resource allocation, and budget optimization. Without proper cost management, Kubernetes deployments can quickly become cost-prohibitive.

Next, let’s highlight the main difficulties faced in controlling Kubernetes costs from a FinOps perspective:

  • Resource Asymmetry: Kubernetes environments host diverse workloads with varying resource needs and are managed by complex scoring algorithms. Naturally, resource allocation becomes challenging.
  • Fluctuating Resource Consumption: Dynamic resource usage in Kubernetes workloads leads to constant changes and requires frequent adjustments for optimal resource utilization and cost efficiency.
  • Missing Requests and Limits: Inadequate definitions of resource requests and limits can result in pods consuming all available resources. It can affect the overall performance and increase costs.
  • Cost Allocation Challenges: Kubernetes clusters are shared among teams, making it difficult to assign costs accurately to individual containers and track resource usage effectively.
  • Dynamic Nature of Environments: Containerized environments undergo frequent changes in pod placement and node allocation. These require real-time adaptation of cost management strategies.
  • Integration with Non-Kubernetes Resources: Integrating cost allocation for non-Kubernetes resources with Kubernetes resources poses challenges in achieving a unified view of resource costs.

By applying FinOps principles to your Kubernetes environment, you can gain granular visibility into your cloud spending and implement efficient cost-saving strategies without overspending.

Implementing FinOps Best Practices For Kubernetes: The JUTEQ Way!

JUTEQ, one of the most reputed cloud infrastructure service providers in Canada and the USA, is ready to help you implement FinOps for Kubernetes correctly! Here, we’ll discuss the most useful FinOps best practices for managing your Kubernetes Clusters.

Rightsizing Pods and Nodes To Optimize Container Costs:

Select appropriate worker node types for Kubernetes clusters based on workload characteristics and resource requirements. Ensure containers are provisioned with appropriate resource requests and limits to avoid underutilization or overprovisioning. Utilize tools like the Vertical Pod Autoscaler (VPA) to automatically adjust resource requests and limits based on container usage.

Establish Clear Cost Allocation With Deep Labeling and Tagging Strategy:

Implement an efficient resource tagging strategy for all cost drivers, including organizations, folders, projects, resources (such as compute cores, RAM, GPUs), namespaces, and labels (cost centers, app names, environments). By meticulously labeling these elements, organizations can optimize cost overruns and ensure Kubernetes workload costs align with quotas or budget caps.

Proportional Cost Allocation With Fixed Budgets and Policies:

Define budget thresholds and cost policies before allocating cluster costs among different groups, such as namespaces or labels. Assess the proportion of resources consumed by each group within the cluster and assign the corresponding percentage of total cluster costs back to those groups. For example, if four namespaces consume 25% of the cluster resources each, allocate 25% of the total cluster costs to each namespace.

Configure QoS & Enforce Tenant-Level Logical Separation For Kubernetes Components:

Define Quality of Service Classes (Guaranteed, Burstable, Best Effort) based on resource limits and pod requests. Improve node resource utilization by assigning pods to appropriate QoS classes. Allocate ResourceQuota objects to namespaces to regulate resource consumption. Set limits and requests for memory and CPU to ensure fair share distribution among namespaces. Monitor resource usage per namespace to identify and optimize cost overhead for each team or service.

Linking Monitoring With Cost Transparency:

Establish monitoring and labeling as automated practices to enforce consistency and efficiency. Maintain a list of approved labels endorsed by business and finance for consistency. Avoid naming conflicts in monitoring tools to prevent confusion and maintain clarity. Incorporate in-code labeling to develop a habit of proactive monitoring and labeling to ensure timely and accurate cost insights.

Developer Empowerment for Cost Awareness:

Integrate cost metrics into existing monitoring dashboards and CI/CD pipelines. Leverage Kubernetes-native tools like custom metrics APIs or Prometheus exporters to expose container cost data. Empower developers to track and optimize Kubernetes resource utilization. Encourage teams to incorporate cost data into their monitoring and decision-making processes.

FinOps Tools Selection For Monitoring And Managing Kubernetes Costs

Before investing in FinOps tools designed explicitly for Kubernetes environments, you need to know the best options! The following tools provide insights into cost drivers, identify optimization opportunities, and help you track your progress toward cost-saving goals.

  • Cloud Cost Management Tools: Organizations can utilize open-source cloud cost management tools, such as Apache CloudStack, Grafana, and Prometheus for cost visualization and optimization without additional expenses. Other cloud-native cost management tools from significant cloud providers include AWS Cost Explorer, Google Cloud Cost Management, and Azure Cost Management. However, these tools are available based on the cloud subscription you pick!
  • Infrastructure as Code (IaC) Solutions: Embrace Infrastructure as Code principles to provision and manage Kubernetes resources efficiently. Popular IaC languages dedicated to specific cloud providers include Bicep for Azure, AWS CloudFormation for AWS, and Deployment Manager for GCP. Another popular IaC tool is Terraform, which enables you to define infrastructure configurations programmatically across Azure, AWS, GCP, or any other cloud provider.
  • Kubernetes Cost Management Platforms: Consider community-driven platforms like KubeCost, Lens, and Goldilocks that provide cost visibility and optimization features tailored for Kubernetes deployments. You can pick a single package or SaaS to use these platforms and enjoy cost visibility and budget management features without vendor lock-in.

Note: While many of these tools offer cost-saving benefits, some have associated expenses you must pay!

You must evaluate FinOps tools based on scalability, integration capabilities, and cost-effectiveness. You might use Native Tooling to configure billing dashboards and set up alerts for cost anomalies across your Kubernetes Clusters. However, always seek help from professionals like JUTEQ experts!
