CoreStack has positively impacted my organization by saving hours of time for reporting—for example, the governance report which my employees used to take at least four hours for one customer.
Senior Vice President at a tech services company with 10,001+ employees
CoreStack support would be around a nine on a scale of one to ten.
Director - SOC & Architecture at a tech vendor with 5,001-10,000 employees
I have interacted with CoreStack's customer support, and we managed to obtain a technical demo from their team for my team from time to time.
Associate Vice President at Hitachi Systems India Private Limited
My advice is to define a FinOps operating model before focusing too much on the tool, ensuring clear ownership, a good tagging strategy, cost allocation rules, and agreed KPIs.
Sr at a tech services company with 10,001+ employees
The customer support from Flexera team has been great, helping my organization integrate and utilize Flexera effectively.
Ai Engineer at IBM

We haven't encountered any issues regarding scalability; the SaaS platform easily accommodates our growth.
Senior Vice President at a tech services company with 10,001+ employees
I can scale up according to business requirements.
Senior Cloud Engineer at a energy/utilities company with 1,001-5,000 employees
Currently there is a significant amount of data we need to fix in the system because we migrated from an old platform to a new platform and carried irrelevant or even incorrect data across.
Software Asset Manager at a financial services firm with 10,001+ employees
I rate Flexera Cloud Cost Management's scalability quite highly, around eight out of ten, as it is well-suited to large enterprise environments, handling multiple cloud providers, subscription accounts, business units, and large volumes of cost and usage data.

Room For Improvement

CoreStack needs enhancements in stability, UI, integrations, customization, security, cost optimization, and AI for improved user experience.
Flexera Cloud Cost Management needs improved usability, integrations, automation, UI/UX, and enriched insights for an enhanced user experience.
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
Specifically, integration with vulnerability management tools and ticketing tools like Jira was not available, so having that would be beneficial.
Director - SOC & Architecture at a tech vendor with 5,001-10,000 employees
Flexera Cloud Cost Management can be improved by developing a normal chat interface or application where non-technical users do not have to navigate through Flexera API application or website.
Ai Engineer at IBM
Another suggestion is to deepen the AI-driven auto-remediation; Flexera Cloud Cost Management is excellent at providing recommendations, but it still requires a manual click to approve or a custom script to execute an action.
Senior Cloud Engineer at a energy/utilities company with 1,001-5,000 employees
Specifically, I would want purchase orders created from an on-premises licensing perspective to be replicated or pulled through from a SaaS visibility view so that licensing tracking happens seamlessly.
Software Asset Manager at a financial services firm with 10,001+ employees
 

Setup Cost

CoreStack offers competitive and transparent pricing, manageable setup costs, and flexible licensing for complex enterprise cloud environments.
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
I had no concerns about pricing, setup cost, and licensing since the cost was nominal and good.
Director - SOC & Architecture at a tech vendor with 5,001-10,000 employees
I remember briefly discussing the cost and had an understanding that there would be an expense associated with upgrading from the older version of Flexera to Flexera One edition that we have now.

Valuable Features

CoreStack enhances compliance, efficiency, and cost-effectiveness through FinOps, governance, and centralized reporting, reducing misconfiguration by 25%.
Flexera Cloud Cost Management enhances efficiency by optimizing costs, integrating multi-cloud platforms, and improving accountability and decision-making.
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
Flexera Cloud Cost Management provided complete visibility across our multi-cloud footprint, allowing us to identify zombie resources, idle dev environments, and unattached storage, resulting in an immediate fifteen to twenty percent reduction in monthly waste simply by cleaning up what we were not using.
Senior Cloud Engineer at a energy/utilities company with 1,001-5,000 employees
The dashboard of Flexera Cloud Cost Management is easy to navigate and understand, providing a complete view of multi-cloud in a single platform, and the integration with AWS, Azure, or GCP is very smooth.
Iam Analyst at a renewables & environment company with 1,001-5,000 employees
A particular strong differentiator regarding Flexera Cloud Cost Management is the ITAM and FinOps integration you have within the same solution, which is really rare in this market.

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.

Automated governance has eliminated shadow spend and now provides clear multi-cloud accountability
Flexera Cloud Cost Management could improve by modernizing the user experience, as many users find the interface feels a bit dated compared to cloud-native competitors such as Vantage or CloudHealth. Another suggestion is to deepen the AI-driven auto-remediation; Flexera Cloud Cost Management is excellent at providing recommendations, but it still requires a manual click to approve or a custom script to execute an action. I suggest simplifying Flexera Cloud Cost Management SaaS platform because Flexera Cloud Cost Management's special sauce is software asset management. Integrating those on-prem licenses with cloud usage can still be complex to set up for a user.
