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.

The role of containers in DevOps and CI/CD pipeline
Posted on March 1, 2025, Level beginner Resource Length medium
DevOps and CI/CD are two significant methodologies that have changed software development in modern times. DevOps unites development and operations teams, and software delivery can become rapid and efficient with them. CI/CD, or Continuous Integration and Continuous Delivery, tests and releases software via automation to deliver software updates in a reliable and efficient manner to its users. By apiculus.com.

Ansible tutorial for beginners: Playbook, commands & example
Posted on February 24, 2025, Level beginner Resource Length medium
Ansible is an open-source automation tool that simplifies software provisioning, configuration management, and deployment across Unix-like and Windows systems by using infrastructure as code principles. Its standout features include ease of installation, agentless architecture (utilizing SSH for connections without requiring additional client-side installations), and comprehensive documentation which facilitates its use even among those with minimal system administration skills. Ansible's modularity supports large-scale orchestration efforts, making it ideal for managing complex environments. By David Carter.

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.

Wasm vs. Docker: Performant, secure, and versatile containers
Posted on August 18, 2024, Level intermediate Resource Length medium
Docker and WebAssembly (Wasm) represent two pivotal technologies that have reshaped the software development landscape. You've probably started to hear more about Wasm in the past few years as it has gained in popularity, and perhaps you've also heard about the benefits of using it in your application stack. This may have led you to think about the differences between Wasm and Docker, especially because the technologies work together so closely. By Savannah Ostrowski, and Sohan Maheshwar.
