Why DevOps? – A play: “All in the same boat”

Posted on 12 November 201310 April 2020 by Christophe ROCHEFOLLE

A play inspired by Patrick Debois, on the 3rd anniversary of Paris JUG, on February, 28th 2011.

devops – Paris JUG 2011 from Patrick Debois

The Actors

Business – Stackholders

Imagine solutions to maximize the value of the services offered by the company.

Developers – Dev

Artisan-artists creators of applications

IT Operations – Ops

Monitor and pilot every day, catch a storm in case of an incident

Users

Services consumer:

  • imagined by the business
  • designed by developers
  • made available by IT operators

… but often forgotten in the process…

Act 1 – Speed at the expense of Quality

The business wants a very simple application for its users for tomorrow…
… Dev prepared it on theirs own servers …
…most of the time with great results…
… sometimes, not!!!

Act 2 – Quality Control is expensive and slows down …

To limit the pitfalls, devs are trained…
… particularly in software architecture
… and get certifications,
… choose modern, resilient languages, frameworks, architectures
… Ops set up virtual machines to create different environments
… for testing, pre-production…
… invest and improve their infrastructure…
Quality is back, but the deadlines, the costs remain too important…
… which generates disgruntled business and users !!!

Act 3 – Becoming Agile

We are getting closer to the Business to share together the same vision of the project:

Résultat de recherche d'images
… we deliver faster…
… taking some risks…
… while Ops manage what they can in Production!

Final Act

Application development has values only if it is operated in production !!!

And never updated Production is doomed:

After having brought together the Business and development team with Agility and in particular Scrum:

It is mandatory to embark IP Operation – Ops:

Quality and customer satisfaction are everyone’s business!

That’s why you need a DevOps approach.

Le train est un choix, pas uniquement parce que je bosse dans une filiale du groupe SNCF, pas uniquement parce que mes 2 grand-pères y travaillaient mais surtout car c’est un moyen de transport eco-responsable 🌳🌳🌳 #monAnneeSncfConnect #sncfconnect pic.twitter.com/Z5EW…
