What are DevOps Practices?

Description of the image

A reliable method for doing this is through the use of DevOps which allows development (Dev) and operations (Ops) teams to develop applications and services at great speed.

Understanding Key Pillars of DevOps

DevOps is not just a toolkit. It's a cultural shift that emphasizes collaboration, communication, and automation throughout the software development lifecycle. It breaks down between Dev and Ops, enabling a shared responsibility for offering secure and well-performing software. 

These are the primary pillars of DevOps:

  • Culture: DevOps brings a different culture of shared ownership, where developers and operations employees work collaboratively for the same goal. However, encouraging blameless post-mortems enables one to learn from past mistakes and enhance processes such as considering security problems.

     
  • Practices: These are the techniques that are used to achieve DevOps goals. However, these include constant integration and delivery (CI/CD), monitoring, automated testing, and infrastructure as code (IaC).
     
  • Tools: Some tools support DevOps practices like CI/CD pipelines (e.g., Jenkins, GitLab CI/CD), version control systems, monitoring solutions (eg. Grafana, Prometheus), and configuration management tools (e.g., Chef, Ansible). Certain security tools like secrets management solutions and vulnerability scanners (e.g., DAST, SAST) are considered as the main pillar of secure DevOps pipeline.

Core DevOps Practices for Streamlined Delivery

Here is the list of key practices that form the base of a DevOps approach:

  1. Continuous Integration (CI): In CI, the merging code procedure is automated, and it changes from developers into a central repository more often. With this, integration issues are quickly resolved, and security vulnerabilities are detected early. However, static application security testing (SAST) can be simply integrated into the CI pipeline to find out security issues that arise in the development process.

     
  2. Continuous Delivery (CD): The deployment process is automated, and CD is developed on CI. Any code changes are automatically developed and tested, involving security testing, and then deployed to different environments. This immensely helps in quick releases with less amount of risk.

     
  3. Continuous Testing: The role of automated testing is significant in DevOps. Tests such as security tests, integration tests, functional tests, and unit tests are properly integrated into the CI/CD pipeline to guarantee the quality of code and find security issues and bugs. During this phase, Dynamic Application Security Testing (DAST) can be highly beneficial to evaluate issues if any.
     
  4. Infrastructure as Code (IaC): IaC works by treating infrastructure as code and authorizes it to be managed and provisioned similarly to application code. With this, consistency, simple configuration management, and repeatability are achieved in environments involving enforcing security practices in infrastructure configurations. 

     
  5. Monitoring and Observability: Monitoring of applications, security posture, and infrastructure more often is crucial to find out and solve potential issues early on. DevOps focuses on observability and gives a detailed analysis of security vulnerabilities, system health, and performance. However, Security Information and Event Management (SIEM) tools can be simply integrated to gather and examine security logs for potential threats.

Advantages of DevOps Practices

Implementing DevOps practices will improve your development process with the extra perk of security:

  • Faster Time to Market: Smooth workflows and automated deployments help in faster releases. This permits various businesses to respond early to market needs in a better way.
     
  • Improved Software Quality: Early and frequent testing with CI/CD pipelines leads to a higher quality of code, fewer defects in production, and reduced security vulnerabilities.
     
  • Reduced Risk: Automation helps in decreasing human error and guarantees regular and consistent deployments within environments like enforcing security practices.
     
  • Enhanced Collaboration: DevOps enables closer work between Dev, Ops, and security teams. This results in better communication and understanding of each other's hurdles.
     
  • Increased Innovation: If releases are done early on and a focus on continuous enhancement helps in forming an environment that promotes experimentation and innovation while maintaining a secure development lifecycle.

How to get started with DevOps?

Application of DevOps in real-life scenarios demands meticulous planning, a step-wise approach, and certain security considerations from the start:

  • Assess Your Current State: Initially, examine your present state of development, security, and operation processes to further find areas that need improvement. All of this involves checking your security posture and finding out potential issues in the development pipeline.
     
  • Define Your DevOps Goals: Define your objectives clearly to adopt DevOps, such as integrating security, quick releases, and enhanced collaboration in the entire development lifecycle.
     
  • Build a DevOps Team: Promote a cross-functional team that includes representatives from security, Dev, and Ops teams. However, this guarantees everyone has a shared understanding of the objectives and the significance of security within the process.
     
  • Start Small and Scale Up: Start by application of some practices, such as integrating security tests and automating deployments into your CI/CD pipeline. Moreover, slowly grow your DevOps practices by gaining relevant experience and confidence.
     
  • Choose the Right Tools: Prefer tools that perfectly match your team's security and workflow requirements. However, open-source tools are a good beginning point, with many offering built-in security features. Thus, you can also explore Security Code (SaC) tools, which can assist in automating security checks within your IaC pipelines.
     
  • Measure and Improve: Regularly examine your DevOps practices and measure their influence on your software delivery process involving security metrics. Also, track the number of issues caught and solved in the development lifecycle.
     
  • Embrace a Learning Culture: Foster continuous learning and skills development within your DevOps team, where the emphasis is on security practices. In your team, involve security awareness training and workshops to make sure that everyone knows their role in developing secure software.
     
  • Security Champions:  Find out security masters within your DevOps team to promote security awareness and key practices. However, these people can work as a linking source between security teams and development teams.

Conclusion

DevOps practices are helping to remake the way software is developed and delivered. As it breaks down silos, fosters collaborative work, prioritizes security, and automates processes, DevOps helps various businesses to achieve quick time to market, competitive edge, and good quality software. Moreover, by following this set of practices and adapting them to industry needs, you can achieve a successful DevOps journey and provide unique solutions with low risk.
