Common Problems DevOps Attempts to SolveI need more server (node) capacity

Wouldn’t it be great if I could test my system on the production environment?

Something went wrong, whose fault was it?

Monitoring System alerts are becoming meaningless

We don’t have time to build all this test automation• But everyone has the time to fix the problems that could have been avoided

We’re too busy, that stuff you speak about to save time will take time and resources away from critical systems development

The hero of a past issue develops a solution that now becomes the single point of failure6

I NEED MORE SERVER(NODE) CAPACITY

The most common complaint from the businessOps team are now seen as blockers who are not sensitive to the needs of businessVery common for there to be demand for more capacity and then an immediate decrease in this demand with no real reason givenRemember – Ops teams are not just responding to the above requests, but they are also dealing with:• System outages• System defects

I’M SURE EVERYTHING IS WORKING…

I need access to something like the production environment to really test what I’ve built

ANOTHER PROBLEM –WHO CAUSED IT THIS TIME?

Productionenvironment

BusinessOps Team: Why can’t you get the capacity right?

Dev TeamOps Team: Why can’t build software that works?

Who should we take aim at?

THIS MONITORING SYSTEM IS CRAZY…

Nothing here is making sense, there’s too many alerts!

Alert fatigue…• Alerts become meaningless

Application and Network Performance Management Systems

THE HERO OF PAST…

I’ve got a great solution, it’s quick and easy…

That solution that hero came up can be done again, let’s do it. Don’t write it down, it’s a temporary thing…

Sometime later, there is a plethora of scripts, no categorisation in place

A None DevOps World

We are going to spend some time trying to understand the issue what DevOps is trying to tackle

We will do this through a case study “The Atomic Clock”

You will divided into three teams• Business Analysts

• Developers

• Operations

Each team will be given a document describing how they should approach the problem

THANK YOU

Hope you enjoyed this learning journey.
