When we are discussing about carbon impact of Kubernetes, also we should discuss about Kubernetes. As we aware Elasticity, Scalability and Resiliency are some of the key-enablers to host microservices on Kubernetes platform. But same time, today’s worlds seeing their cloud cost got increased after they migrated. In this post let’s understand about how to reduce Kubernetes Cost,

Introduction

The advantages of Kubernetes infrastructure like portability and scalability, its open-source base and the ability to increase developer’s productivity have made container technologies a popular choice for many companies, and Kubernetes has become the standard for running container-based apps across clouds. More than 80% of companies today run containers in production and 78% of them use Kubernetes services.

As the containerized infrastructure is obtaining widespread adoption and Kubernetes technologies are gaining momentum, it’s becoming crucial to understand how to get a clear picture of spending on K8s resources, enforce cost optimization opportunities and enhance Kubernetes performance.

The reality shows that it’s not enough just to use Kubernetes to get the best value of public clouds. According to a recent StackRox report, about 70% of companies detected misconfiguration in their Kubernetes environment.

A containerized structure creates significant difficulties with cloud transparency, allocation and performance that cause challenges in resource management and optimization.

The whitepaper goes over the top management challenges of Kubernetes performance, describes recommendations and technical tips in order to achieve K8s clusters transparency and overcome cost management and optimization issues.

It will help you build a solid management strategy for the Kubernetes environment, make a giant leap forward in improving application performance and reduce its infrastructure cost.

Challenges of analyzing Kubernetes costs

Let’s understand why Kubernetes is so complex when it comes to cost optimization:

  1. Shared compute resources — Applications are packaged in pods and run in shared compute resources. The monthly bill from the cloud provider will not give visibility at pod level and thus becomes a black hole for us.
  2. Right sizing of pods — If the pods are not sized with right requests and limits, this will have a direct impact to node being underutilized and paying for unused resources.
  3. Right sizing of persistent volumes — Cost will increase if the persistent volumes are not rightly sized.
  4. Orphan resources — Over a period of time, there are many orphan volumes and resources exist in the cluster which are lying there and burning cost without being in used.

How to Control Kubernetes Cost?

There is no direct solution available to control the Kubernetes, but there are some tools which can helps us to analyze the cost and help to control the cost.
