An introduction to Puppet
Puppet is a powerful open-source configuration management and automation platform that enables organizations to implement Infrastructure as Code (IaC) with precision and scalability. Since 2005, it has become a cornerstone for managing IT systems, deploying software, and enforcing consistent configurations across diverse environments.
How Does Terraform Differ From Puppet and Ansible
In the world of IaC there are a multitude of processes that we use to define but also configure environments. Are they really that different?
Should I be worried about moving to Opentofu from Terraform
This is an insightful question that goes to the heart of current Infrastructure as Code (IaC) governance and risk management.
HAProxy Load Balancing with Docker: A Complete Guide to Building a Two-Node Cluster
Complete guide to building HAProxy load balancing with Docker. Step-by-step tutorial with Docker Compose, health checks, failover, and production best practices.
Zero Downtime Evolution: How Blue Green Deployment and Dynamic Infrastructure Power Service Continuity
To mitigate risks associated with frequent changes, strategies must ensure continuity. Blue-Green deployment is used for safely deploying large or risky changes by shifting traffic between two fully provisioned environments. If issues arise, an instantaneous rollback to the old environment prevents customer impact. Rolling Updates and Canary Replacement are employed for more incremental, lower-risk updates.
