Templatized pipelines have improved efficiency while limitations in code-based development remain
Harness UI can do a lot of good things. Harness's UI should not feel very complicated. At the current stage, it feels very commercialized and compared to other platforms such as Argo CD or Jenkins, which feel much more lively and much more simple. Infrastructure as code or pipeline as code is something that Harness severely lacks. There is not a lot of good support for pipeline as code, and I often find myself not using pipeline as code the way other platforms such as GitHub Actions or Jenkins integrate pipeline as code. Pipeline as code is definitely one of the disadvantages when it comes to Harness. Additionally, the entire platform feels very commercialized, which is something that a lot of developers, especially open-source enthusiasts, might not appreciate even within the organization. One of the very important key factors I observed was that there is no way to execute nested pipelines, which means that we cannot execute child pipelines within child pipelines and child pipelines even within those child pipelines. There is no way to execute nested pipeline execution, which may or may not be required based on the use case, but it is definitely one of those features that I wish the platform had.

Useful features, stable, easy to deploy, and works well
Its logging can be improved. When something goes wrong, it is not always very easy to find the problem. It is hard to identify whether the problem is because of low memory in the server or some configuration in Rational Build Forge. The error logs are not very detailed, and they should provide more information. It should also have more integration with third-party tools. It would be great to have more integration with third-party tools.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Everything in Harness is configured and runs smoothly."
"Some of the best features of Harness include powerful CI/CD pipeline automation, intelligent deployment strategies, and building monitoring, and its automation capabilities significantly improve speed and reliability while saving time by reducing manual operational tasks and the number of employees needed for deployments."
"Harness has positively impacted my organization as several teams have already migrated to it, and some are in the process of moving, reducing the dependency on one specific platform and making it faster with shortened build times and much faster deployments."
"Harness starts integrating with organizations, making everything automated without the need for manual interruption."
"Harness has impacted my organization positively; we use Harness in most of all deployments, so it is uniform."
"Harness positively impacts our organization by reducing deployment time, improving release confidence, and lowering operational overhead during deployment."
"It's a highly customizable DevOps tool."
"The features of Harness are valuable, supporting rolling deployments, basic deployments, and blue-green deployments with zero downtime."
"All features are useful; our customer doesn't have any complaints about the tool, and it works pretty well for what they want and what they need to do."
"Very good reporting features."

Cons

"Infrastructure as code or pipeline as code is something that Harness severely lacks."
"One improvement I see for Harness is simplifying the configuration process for smaller teams or startups, as the platform offers powerful features that new users may require some time to understand."
"Harness setup and configurations could be made easier to configure, which would be helpful."
"I prefer the previous less compact UI version of Harness, which showed more details on the screen."
"When deploying multiple components to multiple environments, like production and BCP, failures sometimes occur. Improvements are needed when deploying one component to one environment."
"There's also room for improvement in debugging pipeline issues, which can sometimes become complex."
"Even with automation, there's a requirement for manual change requests for approvals."
"The initial setup can be complex and time-consuming, and the advanced features may require some learning time due to a steep learning curve."
"Its logging can be improved. When something goes wrong, it is not always very easy to find the problem.
