Implementing a DevOps Strategy across multiple locations & product teams

Over the last 18 months, a change has begun within the Ticketmaster International Team. Barriers are being broken down between the engineering and operational teams, our different product delivery teams are being aligned and knowledge sharing across teams is happening more and more. What’s changed? We developed a strategy based around DevOps to create a leaner higher performing organisation and our journey is underway.

As with many large mature international companies our organisation is probably not unique; our Product delivery & TechOps teams are distributed across 5 geographical locations: Belgrade (Serbia), Gothenburg (Sweden), London (UK), Quebec (Canada) and Stoke (UK). Across these teams we manage about 15 different platforms. Our challenge was to create a DevOps strategy and implement change in a flexible manor is across all delivery teams.

With any distributed organisation we have suffered from communication barriers, although tooling such as Skype, Slack, Zoom, are all helping to break down the barriers. However, more fundamental issues existed such as terminology, multiple tools being used for the same job, skills and abilities differences between locations, and silos. A further example of silos was with our TechOps team being a separated centralised group, with different goals to the engineering team. When different groups that need to work together are not aligned and have different goals this can cause friction. In this case, because the way we’ve been organised, the multiple concurrent requests coming into TechOps from the various engineering teams has caused problems in their ability to service all teams at the same time which causes delays.

The differences in tooling and processes have created a barrier that slows us all down. We needed a new approach and developing a DevOps strategy has been one of the answers for us.

Our DevOps Strategy

In developing our DevOps strategy we wanted all teams to speak the same language, and have a shared understanding and skills. We wanted to break down the silos that had been built over time, bringing teams closer together and aligning resources to delivering products, so that we can be more agile, nibble, developing and releasing high quality products quickly, efficiently and reliably. Echoing the Agile manifesto principles:

Our highest priority is to satisfy the customer through early and continuous delivery of valuable software – Principle #1

Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale – Principle #3

Coalescing our ambitions and desires, mindful of the agile manifesto principles we defined 4 main objectives for our DevOps strategy:

  • Maximise for delivering business value.
  • Maximise the efficiency and quality of the development process.
  • Maximise the reliability of applications and environments.
  • Maximise for service delivery.

With these objectives we started to define requirements to achieve them. Quickly we ran into a mountain of requirements and with that a prioritisation nightmare: how to prioritise the requirements across 5 global locations and 15+ delivery teams, each with different needs.

The Maturity Models

After several rounds of attempting to prioritise in a sensible way we began to arrange the requirements into themes and with that a Maturity Model evolved; one maturity model for each objective.

Maximise for delivering business value. This goal is centred on continuous delivery, creating fast runways down which we can launch our applications.


Maximise the efficiency and quality of the development process. This goal is centred on continuous integration, creating the environment to launch a battery of automated tests and gain fast feedback to be able to evolve code.


Maximise the reliability of applications and environments. This goal is centred on instrumentation, creating the visibility into the inner workings of our applications for root cause analysis and fault tolerance.


Maximise for service delivery. This goal is centred on organisational change, creating alignment of cross-functional teams responsible for delivering software.


The Maturity Models are great; they provide a vision of what our strategy is. Defining the steps required to progress through to achieving advanced levels of DevOps, we can set long term and short term targets on different themes or levels to be reached.  They’re modular so we can change the strategy if improved technology or processes become apparent, and fill in gaps where some exist.

Flexible Planning

The nice thing about the maturity models is the flexibility they provide. They are maps that can guide you from a low maturity to a high maturity level of DevOps.  If you imagine how you would use maps to plan a route from A to B, depending on various conditions, such as day of week, time of day, potential traffic density, road speed, road works, etc the routes chosen will be most appropriate given a set of circumstances.


The DevOps maturity models are true roadmaps, as opposed to a linear list of requirements, allowing each individual delivery team to navigate their own path dependent on their context based on what is most important to them or what concerns they have at any point in time.  Furthering this flexibility, the Maturity Models allow teams to change their routes and reprioritise their plans in consort with business changes and needs.

When individual teams select and complete a portion of the maturity model no other team has yet reached comes with an additional benefit. The problems solved by those teams can be shared with all other teams allowing them to achieve that same work faster avoiding the potential pitfalls that would have been learnt by the early adopting team.

Even though all product delivery teams have the flexibility to select their own routes to achieving our DevOps objectives, ultimately everyone ends up at the same location. So the maturity models enable various programs of work to be planned across different teams with very different needs and abilities.


As good as our maturity models are they weren’t able to solve a couple of issues which still existed: we’re using multiple tools to do the same jobs and we speak different languages because we use different terminology for the same things. To solve this prior to kicking off our strategy we set up focused working groups to define and agree a set of standards for tooling, definition of terms (e.g. naming conventions), best practices (e.g. code reviews) and core specifications (e.g. Logging, Heartbeats & Health checks).

Our Core Tooling

  •         Git – Source Control
  •         GitLab – Git Management & Code Reviews
  •         Jenkins – Application Builds
  •         SonarQube – Code Quality Reporting
  •         Sonatype Nexus – Package Management
  •         Rundeck – Operational Support
  •         Octopus Deploy – Deployment (Windows only)
  •         Chef – Configuration Management

Standardising our tooling and specifications for implementing instrumentation meant we could reduce support overheads, share knowledge and solve problems once. Guidelines and best practices meant we’re working in the same ways and all have shared understanding. Definition of Terms meant we could all speak the same language and avoid confusion.

With the maturity models and standards we have created a shared vision and enabled flexibility for each product delivery team to plan what they want to work on. We have created a framework that enables all product delivery teams start working on achieving the DevOps objectives in parallel but focusing on what’s important to their needs at any given point in time.
