Key Features of Harness

Alright, so what exactly makes Harness tick? Let's take a look at some of its key features. These are the building blocks that make it such a powerful platform:

  • Continuous Integration (CI): Harness provides a robust CI engine to build, test, and package your code. This is where your code is compiled, tested, and prepared for deployment. The CI component of Harness automates these crucial steps, ensuring that every code change is thoroughly tested before it reaches the deployment phase. This leads to a reduction in errors and promotes a more stable and reliable software development process.
  • Continuous Delivery (CD): This is where Harness really shines. It automates the deployment of your applications to various environments, from development to production. CD ensures that software updates are delivered rapidly and consistently. It automates the deployment process, eliminating manual steps, which helps reduce the risk of errors and speeds up the delivery time. CD also supports various deployment strategies, such as blue-green deployments, canary releases, and rolling updates, allowing for a safer and more efficient deployment process.
  • Pipeline as Code: Define your entire software delivery pipeline in code, making it version-controllable and repeatable. This feature allows you to manage your deployment processes using code, making them more transparent, manageable, and easier to replicate across different environments. You can manage your pipelines in the same way you manage your code – with version control, collaboration, and automated testing.
  • Automated Rollbacks: Harness automatically detects and rolls back failed deployments, reducing downtime and impact. If a deployment fails or introduces errors, Harness can automatically revert to the previous stable version, minimizing disruption and ensuring that your applications are always available. This feature is particularly valuable for critical applications where any downtime can have significant consequences.
  • Deployment Strategies: Support for various deployment strategies like canary, blue/green, and rolling updates allows for safer and more controlled deployments. Harness offers a range of deployment strategies that allow you to roll out your applications in stages, reducing risk and allowing for quick rollbacks if needed. These strategies help to minimize the impact of deployments on end-users by gradually introducing new versions of the application.
  • GitOps: Integrate with Git for version control and automated deployments, embracing the GitOps methodology. This approach allows you to manage your deployments through Git, treating your infrastructure and applications as code. This improves collaboration, version control, and automation capabilities.
  • Service Reliability Management (SRM): Monitor the performance and reliability of your services with built-in SRM capabilities. SRM focuses on measuring and improving the reliability of your services. It helps teams understand how their services are performing and provides insights to improve performance. This capability ensures that services meet the required service level objectives (SLOs) and provides proactive alerting to prevent potential issues.
