When simulating your architecture for a specific cloud provider, Holori will estimate the costs of deployment and benchmark it to other cloud providers. You can manually change cloud providers services, locations, VM size, commitment etc. and try different alternatives to find the best mix of price and performance for your infrastructure. You can also enter you on premise costs and use Holori tool to compare cloud providers costs versus on premise costs.
Holori cloud diagram is linked to Holori cloud calculator which centralizes all cloud providers services and price. Prices are updated on a regular basis.
