Keep everything in version control, build and test every change automatically, deploy the same way every time, define infrastructure as code, monitor and alert, test backups, put security checks in the pipeline, and measure with DORA's five metrics. Adopt them in that order.
This is the main guide in our DevOps series. The guide on setting up a CI/CD pipeline goes deeper on the second and third practices.
1. Everything in version control
Application code, configuration, database migrations, infrastructure definitions and deployment scripts all live in version control, with every change reviewed. Nothing is changed by hand on a server. This is the foundation every other practice rests on: if it is not in the repository, it cannot be tested, repeated or rolled back.
2. Continuous integration
GitHub's documentation on continuous integration describes it as a practice of committing code frequently to a shared repository, where it is built and tested automatically, catching errors early and cutting debugging time. Run fast tests on every commit and block merging when they fail.
3. Continuous delivery and deployment
GitHub describes continuous deployment as using automation to publish and deploy software updates, with code built and tested before it is deployed. Deploy the same way to test and production, in small changes, with a rollback ready. Our guide to CI/CD pipelines walks through the setup.
4. Infrastructure as code
Define servers, networks, databases and permissions in code files rather than clicking in a console. Environments can then be reviewed like code, rebuilt after a failure, and copied for testing. Keep secrets out of the code, in the cloud provider's secret store.
5. Monitoring, alerts and backups
You should hear about a problem before your customers do:
- Uptime and error monitoring for every public service.
- Alerts that reach a named person, for problems users would notice.
- Logs kept long enough to investigate incidents.
- Backups run automatically and restored on a schedule to prove they work.
6. Security in the pipeline
Check dependencies for known vulnerabilities on every build, scan configuration, and keep access to production narrow. Three of the categories in the OWASP Top 10 2025 sit squarely in DevOps territory: software supply chain failures (A03), security misconfiguration (A02), and security logging and alerting failures (A09).
7. Measure with the DORA metrics
The DORA metrics (guide last updated January 2026) measure software delivery with five numbers, grouped into throughput (change lead time, deployment frequency and failed deployment recovery time) and instability (change fail rate and deployment rework rate). Track them monthly; they show whether practices are working.
DORA's 2025 research on AI in software delivery finds that AI acts as an amplifier, and that the greatest returns come from focusing on the underlying team and system practices. The practices above are that foundation.
The order to adopt them
For a small team starting out:
- Version control for everything, with reviews.
- Continuous integration with automated tests.
- Monitoring, alerts and tested backups.
- Automated, repeatable deployments with rollback.
- Infrastructure as code.
- Security checks in the pipeline.
- DORA metrics, reviewed monthly.
Common mistakes
The faults we see most:
- Buying tools before fixing habits. A pipeline cannot help code that is not in version control.
- One person holds the keys. Document and share access before that person is away.
- Backups never restored. An untested backup is a hope.
- Measuring activity, such as number of deployments alone, without failure and recovery.
Conclusion
DevOps practices for small and mid-size teams start with version control for everything, continuous integration and repeatable deployments, then infrastructure as code, monitoring, tested backups and security checks in the pipeline, measured with DORA's five metrics. Adopt them in order; each makes the next easier.
