Raiffeisen Bank Aval, one of the top five commercial banks in Ukraine, faced a significant challenge in modernizing their private cloud infrastructure. The bank was struggling with validating hardware requirements against purchase recommendations made by the hardware vendor. This resulted in an expected additional 33% in hardware costs for the transformation project. The existing cloud environment had a VM-to-host ratio of 24:1, and it consisted of 38 VMware hosts and 923 virtual machines. The bank needed a solution that would help them avoid these additional expenses and ensure that their private cloud resources were perfectly aligned to workload demand patterns and business cycles.
