Independent Consultant at Toby Champion Associates
Ensures a robust, user-friendly virtualization platform with seamless VM management, efficient resource allocation and a strong community for support
Improvements are needed for the API. Currently, there are several features inaccessible through the API, necessitating the use of either the WebUI or the command line interface. While the command line interface suffices, it's apparent that efforts are underway to enhance this aspect. In future releases, one potential feature enhancement could be improved remote screen access, allowing users to connect to the screen of another machine more seamlessly. Additionally, integrating with Terraform or providing better support for Terraform workflows might be beneficial, as there seems to be some lacking in that area. There's a minor inconvenience where you have to switch the license file from the open-source community license to an enterprise license.

Hybrid cloud integration provides seamless management while multiple cloud optimization is needed
I have concerns regarding VMware's strategy, particularly about how it manages multiple cloud environments since clients and my company need to navigate multiple clouds. The ability to manage all these environments through a single management interface has become increasingly important. Additionally, companies often arbitrage between different cloud environments, which means we need to optimize workloads based on varying computational abilities and cost points—something I haven't seen fully addressed in your product yet, but which I believe will be necessary. When discussing improvements for VMware vSphere Foundation, many people bring up cost as an issue, but I don't consider that to be the main concern. A key aspect to consider is that we often lack a comprehensive understanding of all the moving parts related to how the product evolves. The conversation we've had illustrates that we may not fully recognize or appreciate all the new features and updates being rolled out.
