In 2026, 70% of Kubernetes clusters are just waiting to be forgotten
Posted on August 3, 2025, Level beginner Resource Length medium
New research reveals 70% of Kubernetes clusters become neglected within 18 months of deployment - a $9.2B cloud waste problem annually. Paradoxically, Kubernetes adoption continues growing (92% enterprise usage in 2025), with companies like Apple and OpenAI running massive node clusters. By dev engineer.

The cost of Kubernetes cluster sprawl and how to manage it
Posted on July 27, 2025, Level beginner Resource Length medium
Kubernetes cluster sprawl occurs when organizations create numerous clusters without proper governance, undermining the platform's core benefits of automated deployment, scaling, and self-healing. This uncontrolled proliferation stems from Kubernetes' deployment simplicity combined with governance gaps, innovation pressure, and infrastructure complexity in multi-cloud environments. The resulting sprawl creates operational inefficiencies, security vulnerabilities through inconsistent configurations, and resource waste from abandoned clusters - ultimately leading to loss of visibility across the Kubernetes ecosystem. By Damon Garn, Cogspinner Coaction.

How Kubernetes requests and limits really work
Posted on November 5, 2024, Level intermediate Resource Length medium
Kubernetes is inarguably an elegant, refined, well-designed edifice of open source enterprise software. It is known. Even so, the internal machinations of this mighty platform tool are shrouded in mystery. Friendly abstractions, like "resource requests" for CPU and memory, hide from view a host of interrelated processes — precise and polished scheduling algorithms, clever transformations of friendly abstractions into arcane kernel features, a perhaps unsurprising amount of math — all conjoining to produce the working manifestations of a user's expressed intent. By Reid Vandewiele.

Securing Kafka communication channels on Kubernetes with TLS/mTLS
Posted on May 1, 2024, Level intermediate Resource Length medium
The article covers a guide on setting up TLS/Mutual TLS (mTLS) for securing communication between Kafka clients and servers, specifically in a Kubernetes environment, thus mitigating potential threats such as man-in-the-middle attacks and unauthorized access to data. We'll be starting off by diving into a bunch of topics that'll help you understand why we're doing what we're doing for our setup. By Aranya Chauhan.

2024 K8s benchmark report: The latest trends in workload reliability
Posted on March 11, 2024, Level intermediate Resource Length medium
According to Gartner, cloud computing will become an essential component of maintaining business competitiveness by 2028. Indeed, in 2024 spending on public cloud services is projected to reach $679 billion. While cloud spend is complex and costs originate from a number of sources, it is undeniable that many organizations are moving apps and services to the cloud and using Kubernetes to manage containers effectively and ensure workload reliability.

Kubernetes best practices for efficient cluster management every DevOps should know
Posted on February 11, 2024, Level intermediate Resource Length medium
Kubernetes is a powerful container orchestration platform that can help developers and DevOps teams deploy, manage, and scale applications more efficiently. However, with great power comes great responsibility. If you are not careful, it can be easy to end up with a complex and difficult-to-manage Kubernetes cluster. By Ben Grady.

Quick guide to scaling AI/ML workloads on Kubernetes
Posted on February 6, 2024, Level intermediate Resource Length short
When running artificial intelligence (AI) and machine learning (ML) model training and inference on Kubernetes, dynamic scaling up and down becomes a critical element. In addition to requiring high-bandwidth storage and networking to ingest data, AI model training also needs substantial (and expensive) compute, mostly from GPUs or other specialized processors.

Continuous blue-green deployments With Kubernetes
Posted on January 23, 2024, Level beginner Resource Length long
In this article author would like to get into the gory details and see how we can create a CI/CD pipeline that deploys a Kubernetes application using the blue-green methodology. The gist of blue-green deployments is to have two identical environments, conventionally called blue and green, to do continuous, risk-free updates. This way, users access one while the other receives updates. By Tomas Fernandez.

Understanding networking in Kubernetes
Posted on November 3, 2023, Level intermediate Resource Length medium
Kubernetes relies on Container Network Interface (CNI) plugins to assign IP addresses to pods and manage routes between all pods. Kubernetes doesn't ship with a default CNI plugin, however, managed Kubernetes offerings come with a pre-configured CNI. By Peter Jausovec.
