Has provided valuable cost insights but could improve in filtering options
AWS Cost Explorer is used to visualize, analyze, and manage spending on the cloud. It can also make a forecast on how much you will spend and gives you information about past costs you had in the cloud in various regions for various different tools. For example, you can see how much it will cost to use a specific product in the future. You can also set a timeline for how much you will use that product to see the effective amount of money you are going to spend. You can compare various tools in order to see which are the most suited tools for your needs and which are the most expensive. You can filter by region and by specific product in order to see which costs are the most important in your organization and cloud environment. You can identify what is not necessary and what you can reduce. It has many good features that you can use with best practices. You can integrate AWS Cost Explorer, and it gives you a better overview of all the related aspects to the costing part of your infrastructure. AWS Cost Explorer is beneficial because you can access a simple interface where you can get an overview of all the costs you have in the cloud environment. You can see which costs you can reduce and how you can move from a specific product to another product in order to reduce costs and improve other aspects. It depends on the specific needs of the organization, but the most important advantage AWS Cost Explorer gives you is the ability to have a clear understanding of your cloud spending.

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.

Pros

"I find the forecasting feature particularly valuable as it helps predict future expenses."
"AWS Cost Explorer is beneficial because you can access a simple interface where you can get an overview of all the costs you have in the cloud environment."
"Currently, I think CoreStack is the best FinOps tool available in the market, which is why we are using it."
"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."
"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."
"Mainly through improved cost visibility and optimization with CoreStack, we have achieved a good ROI, and for some customers we were able to achieve more than forty percent cost savings by identifying unused and idle resources in their accounts, leading to significant cost savings after we completed the cleanup of those resources."
 

Cons

"One disadvantage of AWS Cost Explorer is that you cannot filter too much. You cannot filter data by more than one variable."
"While there is always room for improvement, any needs for enhancement depend on specific requirements at the time. Currently, I cannot pinpoint any specific improvements needed."
"I believe CoreStack already has very good features in the governance and security parts, but stability can definitely be improved."
"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 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."
