A highly stable and scalable solution that provides good out-of-the-box reporting
I am using the latest version of Apptio One. Apptio One is deployed on-cloud in our organization. Apptio One's maintenance involves validating the model and the monthly data loads. I would recommend Apptio One to other users. Before choosing Apptio One, users should ensure they align their use cases to achieve specific and measurable targets. Overall, I rate Apptio One ten out of ten.

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.

Quotes from Members

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

Pros

"Its most significant value lies in its ease of use which extends to both configuration and the subsequent deployment of additional components."
"The TBM model and the out-of-the-box reporting are the most valuable features of Apptio One."
"With Apptio One, the advantage lies in its no-code approach, eliminating the need to write scripts for data retrieval."
"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."
"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."

Cons

"Encouraging or providing more out-of-the-box solutions that cater to a wider audience could enhance the overall effectiveness of the application."
"However, a notable challenge is the requirement to obtain consistent raw data, especially when operating in multiple regions with varying data sets. Each region may have distinct field names or data setups, necessitating the standardization of data before loading it into Apptio One. In Apptio One, there are areas for improvement, particularly in addressing potential bugs. An instance of this is observed when transitioning changes from the development region to the staging or production region. In instances with larger datasets, the calculation process may experience delays. Once the calculation concludes, the process proceeds to the subsequent region, whether it be staging or production."
"The solution's reporting layer, advanced conditional formatting, and reporting features could be improved."
"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."

Pricing and Cost Advice

"Apptio One is an expensive solution."
"Regarding the pricing structure for various products within Apptio, such as APE One or APE One Plus, the cost is intricately tied to the selected license. There are two distinct types of licenses available. Opting for the basic license provides access to APT1, while an alternative license, known as APL One Plus, encompasses additional features like Cloudability and other components. The specific features accessible depend on the chosen license."
"It comes with a considerable cost."
