Swap memory, also known as swap space, is a feature in computer systems that acts as an extension of physical RAM (Random Access Memory). It comes into play when RAM becomes full and the system needs additional space to store and manage running processes. Here’s a breakdown of how swap memory works: RAM Priority: Physical
Demystify GVK in Kubernetes and unlock the power of the Kubernetes API. Learn how GVK helps manage resources, ensures version control, and fosters extensibility.
Kubernetes 1.30, released in April 2024, introduced several new features and improvements. Here’s a breakdown of some key highlights: Enhancing Security: Improved Secrets Management: A new secrets driver facilitates better integration with external secrets management systems like HashiCorp Vault or AWS Secrets Manager. This strengthens security by centralizing secret storage and access control. Bound Service
In the vast world of distributed systems, several algorithms play a crucial role in ensuring smooth operation, communication, and data consistency. Here are some of the most important algorithms to be familiar with: Consensus Algorithms: Paxos (and variants like Raft): These algorithms are fundamental for establishing agreement on a single value among multiple nodes in
In the ever-evolving world of cloud-native deployments, maintaining a stable and predictable environment can be a challenge. Kubernetes, the popular container orchestration platform, tackles this challenge through various mechanisms, with the reconciler pattern being a cornerstone of its functionality. What is the Reconciler Pattern? The reconciler pattern is a design approach that ensures a system’s
System calls are the essential bridge between user programs and the operating system kernel. They allow programs to access system resources and functionalities that are restricted for security reasons or require privileged access. These calls trigger specific actions within the kernel, and the program execution is paused until the kernel completes the requested service. Here’s
Kubernetes offers a powerful platform for containerized applications, but a crucial decision arises: manage your worker nodes yourself or leverage a managed service. Both options have their merits, and the optimal choice depends on your specific needs and resources. Understanding Worker Nodes: The Workhorses of Kubernetes Worker nodes are the grunt workers in your Kubernetes
Kubernetes offers immense power for container orchestration, but managing the control plane can be a complex and time-consuming task. Here’s why a managed control plane should be a strong consideration, regardless of your specific Kubernetes deployment. The Control Plane: The Brains of the Operation The Kubernetes control plane acts as the central nervous system of
Linux is renowned for its versatility, and its networking capabilities are no exception. But just like a high-performance car, tweaking some settings can unlock its true potential. This article delves into methods for tuning your Linux system to become a networking champion. Understanding the Landscape: Assess Your Needs Before diving into specifics, it’s crucial to
Running Kubernetes in production is fantastic, but sluggish DNS resolution can bring your applications to a crawl. Here’s where NodeLocal DNS swoops in, a secret weapon for keeping your containerized world running smoothly and scaling like a champ. The DNS Dilemma: Traffic Jams in Your Cluster Normally, Kubernetes relies on a central service called kube-dns
