The storage for local usage is very efficient for an HCI product but virtualization needs improvement
Azure Site Recovery is brilliant. The integration with Azure using Azure Arc is excellent. Additionally, Azure storage for local usage is very efficient for an HCI product. There has been some return on investment in terms of time usability and reduction of footprint, and obviously, HCI two emissions and other factors.
