Climb the five steps of a continuous delivery maturity model

In this article, you will get to know the ins and outs of a DevOps Maturity Model and how you can take a step further in your DevOps journey. When I started to work with Kubernetes, It was a bit annoying to deal with multi clusters from CLI at the same time. Most common ones are Jenkins from CloudBees, Travis CI, Go from ThoughtWorks, and Bamboo from Atlassian.

Test automation tools include pipeline software like Jenkins; test automation systems like Selenium or Cypress; and cloud services, including AWS CodePipeline or Microsoft Azure DevTest Labs. There are many paths to take into this realm, we can approach ci cd maturity model from a tool perspective — how to choose the tool that is right for you. There are many open source and commercial tool offerings, each claiming to simplify the development team’s work while increasing confidence in the published artifacts.

The application is built to be fully configurable and easily adaptable, by modifying the data file (js/data/data_radar.js). The default data file contains a sample data set, based on a fictions financial institution’s gap analysis. Continuous Delivery presents a compelling vision of builds that are automatically deployed and tested until ready for production. One way of accomplishing that is to have a separate stream or category of issues assigned to the DevOps teams in charge of infrastructure provisioning. This will allow the testing each modification made in order to guarantee a good QA.

Instead of trying to retrofit infrastructure as code into the existing CD Maturity Model, I believe it is more effective to independently apply the model’s five levels of maturity to infrastructure as code. To that end, I have selected many of the best practices from the book, Infrastructure as Code, as well as from my experiences. Those selected practices have been distributed across the model’s five levels of maturity. One of the first considerations a PM needs to address is the project team’s Release Management Maturity.

• In a recent survey, 69% of IT decision-makers indicated that they were shipping new features to production once per day or more.
• The automation phase, the third level of DevOps maturity, involves more automation to perform essential tasks.
• Each of these Continuous Delivery maturity models mentioned define their own maturity levels.
• Information must e.g. be concise, relevant and accessible at the right time to the right persons in order to obtain the full speed and flexibility possible with Continuous Delivery.
• Collaboration is one of the most crucial aspects of DevOps maturity that requires understanding each team member’s role and sharing the tools and resources available to reach a common objective.

We’ve put together a high-level CI / CD Maturity guide to help with these challenges. We list all the processes and practices that need to be in place before you can truly claim that you have made Continuous Deployments possible. The guide makes certain basic assumptions i.e. it assumes your code is managed in a version control system.

Understanding DevOps Maturity

Finally, fast forward to June 2016, O’Reilly releases Infrastructure as Code Managing Servers in the Cloud, by Kief Morris, ThoughtWorks. This crucial work bridges many of the concepts first introduced in Humble and Farley’s Continuous Delivery, with the evolving processes and practices to support cloud computing. DevOps describes the adoption of iterative software development, automation, and programmable infrastructure deployment and maintenance.

At beginner level, the monolithic structure of the system is addressed by splitting the system into modules. Modules give a better structure for development, build and deployment but are typically not individually releasable like components. Doing this will also naturally drive an API managed approach to describe internal dependencies and also influence applying a structured approach to manage 3rd party libraries. At this level the importance of applying version control to database changes will also reveal itself.

Our test were environment agnostic and was able to give feedback on the state of the system as early as it can get. Depending on your organization, your end goal may be to have changes deployable within a day . Or your goal may be to achieve continuous deployment, with updates being shipped if they pass all stages of the pipeline successfully.

Remember that it’s important to provision the application infrastructure for all required environments, keep environment configuration in check and dispose of any intermediate environments in the process. Or maybe your organization or team is starting to plan to fully embrace DevOps and your team is researching what is exactly what to need to install in order to have the perfect toolchain. https://globalcloudteam.com/ Perhaps you have a gap in some processes that you are not even aware of. Establishing a good and solid DevOps toolchain will help determine ahead of time the grade of the success of your DevOps practices. As you continue to build out the pipeline, your team will need to collaborate more closely with other functions and start taking more responsibility for delivering your software.

Advanced

Level 1 of DevOps maturity is for teams who are just beginning to test the waters of DevOps. That doesn’t mean that they’re immature engineering organizations. Instead, their processes are usually static and familiar, but they might not be serving the organization well. Teams at this level will regularly experience projects that go way over time and budget. When they sit down to try to figure out what went wrong, they’ll make a huge list of things they’ve learned. Then they’ll proceed to repeat those same mistakes on the next project—and the one after that.

Mature teams approach moving through these levels as a process. Again, the heart of DevOps is continuously improving a team’s performance in a variety of ways. Instead of attempting to take a giant step, mature teams take many little ones. Circa 2019, HackerEarth was already doing frequent deployments. We had a process to collect, merge, tag and release code into production. As it must be obvious now, our feedback cycle was not close to the point of failure.

CD Maturity Model – Gap Analysis Visualization Tool

When moving to beginner level you will naturally start to investigate ways of gradually automating the existing manual integration testing for faster feedback and more comprehensive regression tests. For accurate testing the component should be deployed and tested in a production like environment with all necessary dependencies. This is why we created the Continuous Delivery Maturity Model, to give structure and understanding to the implementation of Continuous Delivery and its core components.

What’s more, the way that the team manages projects can introduce problems for the organization. They plan everything, then code all of it, then go through painful rounds of QA and compliance approvals before the code is ready to go to the operations team. Many times, they’ll do all that only to find that operations needs the code changed again. This level is where the hypothetical team that “does DevOps” by installing a Jenkins server lives. Teams at this level often times see operations as their own team, distinct from engineering or project management teams. They’re rarely consulting during the planning or early implementation stages of the project.

By naming and understanding them, it’s possible to identify areas where a business’s culture is strong and areas where that same business is weak. The stage-wise process and the above parameters define an organization’s DevOps maturity success. Organization-wide transformation begins with defined processes and established automation. 2) DevOps Maturity by Data – Determines DevOps maturity by ability to clear path to automate changes to data and validate functionality regularly, through DataOps. Lightrun, so you can add logs, metrics, and traces to your code in real-time, improving productivity with faster debugging. DevOps Maturity by Data – This measures DevOps maturity by the capability to automate data changes and automatically validate functionality regularly by using DataOps.

These build scripts should compile the source code into executable artifacts checking and validating syntax along the way. Some interpreted languages such as PHP do not require a build phase. Continuous Delivery Maturity Models provide frameworks for assessing your progress towards adopting and implementing continuous integration, delivery and deployment (CI/CD).

In this category we want to show the importance of handling this information correctly when adopting Continuous Delivery. Information must e.g. be concise, relevant and accessible at the right time to the right persons in order to obtain the full speed and flexibility possible with Continuous Delivery. Apart from information directly used to fulfill business requirements by developing and releasing features, it is also important to have access to information needed to measure the process itself and continuously improve it. A typical organization will have, at base level, started to prioritize work in backlogs, have some process defined which is rudimentarily documented and developers are practicing frequent commits into version control. The purpose of the maturity model is to highlight these five essential categories, and to give you an understanding of how mature your company is.

phases of a DevOps Maturity Model

However, from our experience you will have a better chance of a successful implementation if you jump start the journey with a dedicated project with a clear mandate and aggressive goals on e.g. reducing cycle time. Build and deployment is of course core to Continuous Delivery and this is where a lot of tools and automation come into the pipeline; this is what is most is commonly perceived when Continuous Delivery is discussed. At first glance a typical mature delivery pipeline can be very overwhelming; depending on how mature the current build and deployment process is in the organization, the delivery pipeline can be more or less complex.

While those teams are a part of the planning and design conversations, they’re not fully integrated. This means that QA and compliance still takes a significant amount of the time between when code is written and when it’s deployed. DevOps Maturity for Application – This measures the DevOps maturity in terms of the ease of moving code from development to production.

Data Management

It’s a path to the advanced capabilities befitting the DevOps major leaguers that deploy multiple times a day or even multiple times an hour. It might seem strange to state that verifying expected business result is an expert practice but this is actually something that is very rarely done as a natural part of the development and release process today. Verifying expected business value of changes becomes more natural when the organization, culture and tooling has reached a certain maturity level and feedback of relevant business metrics is fast and accessible. As an example the implementation of a new feature must also include a way to verify the expected business result by making sure the relevant metrics can be pulled or pushed from the application.

Five levels

While every organization is different, a number of common patterns have emerged. Continuous delivery is a software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time and, when releasing the software, without doing so manually. As part of deployment, you should also review your provisioning tasks and requirements.

The first stage of maturity in continuous delivery entails extending software build standards to deployment. The team should define some repeatable, managed processes that get code to production. Developers shift build and deployment activities off of personal workstations — the usual location for ad hoc chaos — and onto a central, managed system available to all developers and the IT operations team. At this level real time graphs and other reports will typically also include trends over time. Teams at this level devote themselves to continuous improvement. They fanatically measure how their changes impact the business bottom line.
