Room For Improvement

CoreStack needs improvements in cost allocation, security, UI responsiveness, and AWS reporting, with better integration and governance.
Simplify configuration, improve UI, expand features, clarify pricing, and enhance security to improve accessibility and functionality for smaller teams.
The recommendations made in CoreStack to delete a machine have the potential to generate major cost savings.
Associate Vice President at Hitachi Systems India Private Limited
We need more security features, particularly since the market is increasingly demanding better security tools for cloud management platforms, including cloud security posture assessments.
Senior Vice President at a tech services company with 10,001+ employees
Adding features to automate tasks at the operations level could help provide better visibility across the cloud for our operational engineers.
Senior Solution Architect at Hitachi Systems India Private Ltd
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.
Technical Associate at ZS
Improved documentation and onboarding tutorials would help accelerate adoption.
Cloud Platform at Futurescape
Harness can be improved by providing more clarity on the credits it issues for Harness Cloud, as it has a tiered pricing structure involving license and credit costs, which can get confusing.
Quality Engineering Lead at a logistics company with 51-200 employees
 

Setup Cost

Harness pricing is higher than open-source but justified by benefits, with room for improvement in licensing cost noted.
My experience with pricing, setup cost, and licensing is that it is straightforward and has flexible pricing based on workload consumption.
Associate Vice President at Hitachi Systems India Private Limited
I believe has been competitively priced across the market.
Senior Vice President at a tech services company with 10,001+ employees
From what I understand with respect to Harness, licensing and setup costs were relatively low for an enterprise, and the pricing was more catered toward enterprises who would invest in the technology.
Technical Associate at ZS
The licensing cost is a little bit too high.
Cloud Architect at a outsourcing company with 51-200 employees
 

Valuable Features

CoreStack enhances multi-cloud cost efficiency, visibility, compliance, and governance, improving operations, customer satisfaction, and resource savings.
Harness simplifies CI/CD automation with AI-driven processes, enhancing deployment speed and reliability while reducing risks and manual effort.
The single pane of glass for multi-cloud cost optimization helps me day-to-day by bringing a lot of operational excellence; it saves a lot of time because rather than going to each and every account or multi-cloud portal, which takes a lot of time, having everything on a single pane of glass increases efficiency, delivers results in less time, and provides clear reporting that can be shared with the customer in PDF or CSV formats.
Senior Vice President at a tech services company with 10,001+ employees
The best features CoreStack offers are primarily the recommendations for cost optimization for RDS and EC2 machines.
Associate Vice President at Hitachi Systems India Private Limited
For example, from AWS, it provides visibility on EBS volumes that are not being used, and it gives recommendations to delete them and save some cost.
Senior Solution Architect at Hitachi Systems India Private Ltd
Harness uses AI to suggest errors in case of deployment failures.
Senior Software Engineer at a financial services firm with 10,001+ employees
The platform also supports cloud-native environments and Kubernetes deployments, making pipeline management easier, and its automation capabilities significantly improve speed and reliability.
Cloud Platform at Futurescape
If something goes wrong, I can use AI troubleshooting to build or test my fails and analyze the logs, suggesting the fixes.

Featured Reviews

Manmohan Rao - PeerSpot reviewer
Associate Vice President at Hitachi Systems India Private Limited
Cost reports have driven accurate AWS workload optimization and continue to guide savings
I can suggest improvements for CoreStack, especially regarding reporting periods. I noticed that some of the cost optimization reports generated potential savings while considering systems that have only maximum utilization of 1% or 2%. The recommendations made in CoreStack to delete a machine have the potential to generate major cost savings, but such machines should not be listed for deletion if they have maximum CPU utilization of 1%. I have concerns about needed improvements primarily regarding AWS. If a customer is running ten virtual machines and one machine has a maximum of 1% utilization, it is considered as an idle instance in the report, which completely ignores that particular machine. This should not be the approach.

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.
