DevOps - The real stories

DevOps to begin with was seen to be out of reach for a lot of us as we didn't have an environment or requirement anything like a Netflix or fortune 500 but think now that is beginning to sway into the normal when adopting a DevOps practice within any type of business.

You will see from the second link below in references there are a lot of different industries and verticals using DevOps and having a hugely positive effect on their business objectives.

Obviously the overarching benefit here is DevOps if done correctly should help your Business improve the speed and quality of software development.

I wanted to take this Day to look at succesful companies that have adopted a DevOps practice and share some resources around this, This will be another great one for the community to also dive in and help here. Have you adopted a DevOps culture in your business? Has it been successful?

I mentioned Netflix above and will touch on them again as it is a very good model and advanced to what we generally see today even still but will also mention some other big name brands that are succeeding it seems.


In 2010 Amazon moved their physical server footprint to Amazon Web Services (AWS) cloud this allowed them to save resources by scaling capacity up and down in very small increments. We also know that this AWS cloud would go on and make a huge amount of revenue itself whilst still running the Amazon retail branch of the company.

Amazon adopted in 2011 (According to the resource below) a continued deployment process where their developers could deploy code whenever they want and to whatever servers they needed. This enabled Amazon to achieve deploying new software to production servers on average every 11.6 seconds!


Who doesn't use Netflix? obviously a huge quality streaming service with by all accounts at least personally a great user experience.

Why is that user experience so great? Well the ability to deliver a service with no recollected memory for me at least of glitches requires speed, flexibility, and attention to quality.

NetFlix developers can automatically build pieces of code into deployable web images without relying on IT operations. As the images are updated, they are integrated into Netflix’s infrastructure using a custom-built, web-based platform.

Continous Monitoring is in place so that if the deployment of the images fails, the new images are rolled back and traffic rerouted to the previous version.

There is a great talk listed below that goes into more about the DOs and DONTs that Netflix live and die by within their teams.


As with many of us and many companies there was a real struggle around slow and painful deployments. In the same vein we might have also experienced working in companies that have lots of siloes and teams that are not really working well together.

From what I can make out at least from reading about Amazon and Netflix, Etsy might have adopted the letting developers deploy their own code around the end of 2009 which might have been before the other two mentioned. (interesting!)

An interesting take away I read here was that they realised that when developers feel responsibility for deployment they also would take responsibility for application performance, uptime and other goals.

A learning culture is a key part to DevOps, even failure can be a success if lessons are learned. (not sure where this quote actually came from but it kind of makes sense!)

I have added some other stories where DevOps has changed the game within some of these massively successful companies.


Recap of our first few days looking at DevOps

  • DevOps is a combo of Development and Operations that allows a single team to manage the whole application development lifecycle that consists of Development, Testing, Deployment, Operations.

  • The main focus and aim of DevOps is to shorten the development lifecycle while delivering features, fixes and functionality frequently in close alignment with business objectives.

  • DevOps is a software development approach through which software can be delivered and developed reliably and quickly. You may also see this referenced as Continuous Development, Testing, Deployment, Monitoring

If you made it this far then you will know if this is where you want to be or not. See you on Day 7.

Day 7 will be us diving into a programming language, I am not aiming to be a developer but I want to be able to understand what the developers are doing.

Can we achieve that in a week? Probably not but if we spend 7 days or 7 hours learning something we are going to know more than when we started.
