Automated method to build a complete VPC infrastructure (subnets, gateaway, routes, ...) for EC2 instances. It is a highly available Architecture: 3 zones. To automate the process, I use the Terraform application.

This repository showcases a Hadoop cluster setup with High Availability (HA) using ZooKeeper for automatic failover between NameNodes. It ensures minimal downtime and enhanced fault tolerance, providing a reliable framework for large-scale data storage and processing. Configuration details for both Hadoop and ZooKeeper are included.

Archive of old articles from the 1990s–mid-2000s, many still linked to.

This repository contains Linux commands executed, Application code ,Terraform script ,Pipeline scripts and Architecture flow.

Installs and configures corosync-qnetd, the standalone Qdevice Network Quorum Daemon used as an external quorum arbitrator for corosync clusters (e.g., two-node Proxmox VE clusters needing a tie-breaker vote). Installs the package, enabling the HighAvailability repo on EL, and manages the service. Per-cluster TLS trust setup remains a manual step.
