Swap Memory, when and when not to use.


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

Important Algorithms to Know in Distributed Systems


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

How Kubernetes works on a reconciler pattern

Kubernetes and the Reconciler Pattern: Maintaining Order in the Chaos


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

Different types of system calls

Different types of system calls


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 in Production: Should you run your own worker nodes?

Kubernetes in Production: Should you run your own worker nodes?


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 in Production: Should you run your own worker nodes?

Kubernetes in Production: Managed Control Plane – Worth Considering for 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
