 <h1 id="balancing-cost-with-performance-and-reliability">Balancing Cost with Performance and Reliability</h1>
 <p>Kubernetes cost optimization comes down to pinpointing the correct resource allocations and auto-scaling factors for our workloads.</p>
 <p>But "correct" in this context doesn't mean "the least possible amount of resources". It's a delicate interplay of cost vs. performance vs.reliability. </p>
 <p>In order to run our clusters in the most cost-effective way without compromising either performance or reliability it's vitally inportant to understand the Pod QoS model and the implications of PodDisruptionBudget.</p>

+<p>Kubernetes cost optimization starts with correct resource allocation for application containers that Kubernetes orchestrates.</p>
+<p>Each container can have requests and limits defined for either memory or cpu or both. </p>

 In most unoptimizaed clusters we're observing up to 50% of waste, which translates to thousands of dollars or euros monthly.</p>
 <p>This waste comes from over-provisioning the containers in our pods.
 Read on to understand the reasons and perils of over-provsioning.</p>

 <h2 id="idle-resources">Idle Resources</h2>
 <p>Kubernetes comes with a promise of automatic bin packing. I.e - it is supposed to fit the largest possible amount of pods on every node in the cluster. But this is again dependent on engineers correctly defining 1) resource requests and 2) node sizes. Even with smart and well-tuned autoscaling tools like Karpenter this doesn't always work and we find ourselves with nodes that are more than half empty - with resources that were neither requested nor utilized. All these are <strong>idle resources</strong> and taking care of reducing them is an important focus area of Kubernetes Cost Optimization.</p>
