Data Architect at a financial services firm with 1,001-5,000 employees
Unified data platform has improved regulatory compliance but still needs better integration features
It is difficult to say about Azure Stack improvement because I need to revisit and study it again. The pricing is okay, but on the services side, perhaps we need to think about some services, not all. I would not like to see any additional features in the future. To give them more like a 9 out of 10 or 10 out of 10, I think they need to improve on the interface, implementation, configuration, and integration with other products, so I rate them an eight. As compared to AWS, they need to add more features. I would like to see operations and storage features, like AI features or security features.

Have built a flexible virtual infrastructure for internal application hosting and optimized resource allocation
VMware vSAN, HCI is the best feature along with the VMware core suite of VMware ESXi servers. It is basically a part of HCI. In the networking part, VDS is valuable because NSX and similar solutions are required where telecom or multi-tenancy environments exist. Customers running single instances of networks with physical switches rely on actual throughput or load handling by physical switch buffer and memory chipsets. VMware Software Defined Data Center works but at a limited scale. We cannot completely grow or rely on VMware Software Defined Data Center. Though it is very helpful, we have removed entire server layers from the virtual server layer. The flexibility is excellent as we use storage policies, and whenever any VM or dynamic allocation is needed, it is automatically handled by VMware without physical intervention.
