High availability is further enhanced through built-in SLAs (Service Level Agreements) of up to 99.95% for App Services, giving businesses confidence in their uptime commitments.
How Azure Apps Integrate with DevOps
Modern software development relies on continuous integration and continuous deployment (CI/CD). Azure apps are deeply integrated with DevOps practices, enabling teams to deliver updates faster and with higher quality.
CI/CD Pipelines with Azure DevOps
Azure DevOps provides a suite of tools for planning, building, testing, and deploying Azure apps. Developers can automate the entire pipeline—from code commit to production deployment—using YAML-based workflows.
- Automated builds triggered by Git commits
- Unit and integration testing in isolated environments
- Staged deployments (dev → staging → production)
For example, a team can set up a pipeline where every pull request triggers a build and test run, and upon merge to main, the app is automatically deployed to a staging environment for QA. This reduces human error and accelerates release cycles.
GitHub Actions Integration
Not using Azure DevOps? No problem. Azure apps work seamlessly with GitHub Actions, allowing developers to build and deploy directly from GitHub repositories.
- Deploy web apps using pre-built GitHub Actions workflows
