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.

Quotes from Members

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

Pros

"My advice for others looking into using CoreStack is that anyone who is looking to optimize their workload cost for public cloud services should start using CoreStack because of the reports and granularity it produces to optimize cost, which will benefit them."
"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, and since I'm sending out 20 reports every month, that equates to 80 hours, thus saving me two man-weeks every month and approximately $8,000 in pure savings if I estimate $100 an hour for my architect."
"Currently, I think CoreStack is the best FinOps tool available in the market, which is why we are using it."
"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."
"Flexera Cloud Cost Management has helped my organization save money by 20% to 30%, as previously mentioned."
"Flexera Cloud Cost Management provides real-time live data that allows us to see realistic projections based on trends we anticipate, showing where we could possibly end off by year-end."
 

Cons

"I believe the multi-tenancy feature is present, but if it could be improved and secured further, that could be beneficial."
"I give it an eight because, as I mentioned, a few things from the billing operations need to be added, and we need more security features, particularly since the market is increasingly demanding better security tools for cloud management platforms, including cloud security posture assessments."
"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%."
"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."
"While the solution works well, perhaps because we are still in the early stages of becoming familiar with the technology, I would appreciate improvements in the SaaS environment."
"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."
