Thanks to Harshal Shah for creating the framework from scratch and getting me to dig into this.
In this tutorial we are going to setup a complete stack which will collect performance metrics from multiple machines, store it in a datastore and visualise as graphs. Let’s go over the setup, design and role of individual components and then jump into configuring individual components and linking them together.
We have a three layer setup – and this setup is available as a setup of vagrant boxes with associated configuration scripts at github repo.… Read the post
I stumble across interesting reads and I share it with with friend/colleague with whom I might be discussing that problem/technology etc. This series is an effort to document my own reading and filter the most significant once. I don’t want to start a series because for one there are really good once already which I follow (Will elaborate in a separate post soon) and secondly I want to keep it free in form. No fixed schedules like once in two weeks or no fixed length.… Read the post
Puppet is one of fast evolving and widely used infrastructure automation & configuration management platform. Puppet has changed the way infrastructure is built and deployed and continues to innovate the space. Keeping the pace of learning with puppet and in general this domain’s development is a challenging job.
While working, teaching and learning I realized that some of my learning can be useful for others to learn and contribute. So I decided to pen (or keyboard) down my thoughts along with simple use cases where you build things while learning.… Read the post
I met a friend at DevOps conference who used to worked for Sabre. He told me about how huge Sabre is and how it drives world’s travel businesses. I went home and researched the company and left it at that. The “Aha” moment happened when I was working on an assignment related to API management. The sheer magnitude of what Sabre was doing and what many others are doing with APIs was huge and I could make sense of it only after looking at it from API perspective.… Read the post

I was reading through the conversation at DevOps tool-chain group. The problem posted was difficulty of using Jenkins as a delivery pipeline. Specially when it comes to complex workflows for example diamond dependencies, fan out & fan in etc. My thoughts after reading post were (Which you will see being different later):
Though you can use Jenkins to build continuous deliver pipelines, there are better suited and specialized “deployment automation” tools for the job:

Retail organizations sample their products before they launch. The sampling process basically involves having a physical sample manufactured and reviewed by product designers/creators. Product might undergo change based on look, feel, ergonomics, aesthetics and performance of product’s physical sample. The process is iterative at times and leads to lot of waste not only in material, but also in terms of delay and longer product life-cycles.
With emergence of image processing technologies and close to real life graphics, there are ways you can live without physical samples.… Read the post
