Gossip Protocol for Node Failure Detection in Distributed Systems: An Illustrated Guide
Lets break down the concepts of Gossip protocol for node failure detection with a simple step-by-step example and provide a visual overview of how the information propagates. Here’s how a basic failure detection system...
Inside the Box: A Guide to Programmatically Detecting Docker and Container Environments
In an era where containerization has become a standard in software deployment, it’s increasingly important for applications to be able to identify when they’re running within a containerized environment. Whether you’re monitoring resource usage,...
How to Retrieve the Container ID in Java: Working with Docker and Kubernetes
n modern cloud-native environments, applications are often containerized, either using Docker or orchestrated within Kubernetes clusters. Retrieving the container ID of the currently running container programmatically can be useful for debugging, logging, or tracking...
Beyond Clusters: Unlocking the Power of Virtual Nodes in Consistent Hashing
Consistent Hashing is a technique used primarily in distributed systems to efficiently distribute data across multiple nodes. It addresses the challenges of load balancing and data distribution, particularly when nodes are added or removed...

How to detect a VM
In Java, you can check if the current system is running on a virtual machine (VM) by inspecting certain system properties or by checking for specific indicators in the environment. While there’s no direct...
How to check if docker demon is running on TLS or without it
To check whether the Docker daemon is running over TLS (port 2376) or without TLS on port 2375, you can make an attempt to connect to both ports and see which one is available....
Using docker API to listen to stop event in java
This code snippet is a great approach to listen for Docker events, particularly the stop events, using the HttpClient in Java without relying on a Docker client library. The code makes use of the...
