DevOps is more than just a software development methodology – it's a culture. The DevOps culture emphasises 3 main pillars: collaboration, communication, and shared responsibility between development and operations teams. In this post, we will discuss the importance of DevOps culture in software development and how developers and operations teams can benefit from it.

## DevOps is not a Title

This conundrum needs to be addressed. If you’ve seen career titles such as DevOps Manager, and DevOps Lead, it means those individuals are managing the DevOps culture in that team. The title does not necessarily imply the term literally.

## The Importance of DevOps Culture - The 3 Pillars

### Collaboration and Communication

One of the key principles of DevOps culture is collaboration and communication. By breaking down silos between teams, DevOps promotes cross-functional collaboration, which leads to better outcomes. Collaboration between development and operations teams can help identify potential problems earlier in the development cycle, saving time and resources down the line.

Effective communication is also essential in DevOps culture. By sharing information and feedback, teams can work together to ensure that everyone is on the same page and working towards the same goals. This helps identify areas for improvement and implement changes more effectively.

### Shared Responsibility

Another principle of DevOps culture is shared responsibility. In a DevOps environment, developers and operations teams share the responsibility of delivering software. This means that developers are responsible not only for writing code but also for ensuring that it runs smoothly in production. Similarly, operations teams are responsible not only for deploying and maintaining infrastructure but also for providing feedback to developers on how their code is performing in a production environment. In other words, “you build it, you ship it!”; developers can utilise the DevOps tools available to deploy their code to production.

DevOps teams can create a culture of accountability and ownership by sharing responsibility. When everyone is responsible for the success of the software, it creates a sense of ownership and pride in the work being done.

### Continuous Improvement

Continuous improvement is a fundamental value of DevOps culture. DevOps teams continuously seek ways to enhance their processes, tools, and practices. By continuously evaluating and improving their work, DevOps teams can remain competitive in a rapidly changing digital landscape.

Continuous improvement also assists teams in learning from their mistakes. When something goes wrong, DevOps teams utilize the incident as an opportunity to learn and improve. By implementing changes based on what they have learned, teams can avoid making the same mistakes in the future. DevOps teams should always be looking for ways on improving their automation and processes.

## Tools

DevOps teams can employ a range of tools and practices to achieve their goals, such as continuous integration and delivery (CI/CD), automated testing, and infrastructure as code (IaC). By automating tasks and using standardized processes, DevOps teams can reduce errors and improve the quality of their software. Some of the tools include:

- [GitHub Actions](https://github.com/features/actions), [Azure DevOps](https://azure.microsoft.com/en-us/products/devops) - CI/CD tool
- [Terraform](https://www.terraform.io/), [Pulumi](https://www.pulumi.com/), [AWS CDK](https://aws.amazon.com/cdk/), [Azure Resource Manager](https://azure.microsoft.com/en-us/get-started/azure-portal/resource-manager/) - IaC tool
- [SonarCloud](https://www.sonarsource.com/products/sonarcloud/), [Codacy](https://www.codacy.com/) - Code analysis and security tool
- [Azure Test Plan](https://azure.microsoft.com/en-us/products/devops/test-plans/) - Automated testing tool

## Conclusion

DevOps culture is more than just a set of practices; it is a mindset that emphasizes collaboration, communication, shared responsibility, and continuous improvement. By embracing these values, DevOps teams can create a culture of innovation and agility that can help them stay competitive in today's fast-paced digital landscape with the toolsets available.
