This ROI from using Pivotal Cloud Foundry would depend on the organization using it.

The return on investment is greater than the core platform offers because Pivotal has been a key part of the transformation strategy that customers should use when adopting Pivotal Cloud Foundry. In addition to the platform capabilities, the transformation strategy, how to scale teams, how to enable them, and the engineering and transformation approach, Pivotal Cloud Foundry has a strong opinion on these matters. This has helped many customers make big transformations, such as moving from traditional application servers and monolithic architectures to domain development and microservices, as well as DevOps engineering. This has enabled Pivotal Cloud Foundry to offer a meaningful ROI to its customers.

ROI seems to be good. It is helping to be on par with the standards and trends and it is easy to scale, deploy, and quickly roll out. There is also less downtime. So I see so many advantages,

I haven't seen an ROI yet, but I haven't invested a lot of time into the solution yet either.
