An enterprise workload platform, vSphere is used to improve the performance for a data center. It is used to boost operational efficiency, supercharge workload performance, and accelerate innovation.
Longhorn is performing well as storage for databases and in almost any solution that uses exclusive access to volumes (ReadWriteOnce in Kubernetes nomenclature). When write access is required from many clients (ReadWriteMany) Longhorn Block Storage covers its volumes with NFS (file-based) access. Longhorn Block Storage also is well fitted in every architecture where data security (snapshots, backups, multiple replicas) is more important than access speed (in terms on IOPS and MiB/s).
vSphere is well suited for multiple VMWare hosts and can be very useful in larger enterprises where vMotion is used to load balance and failover running virtual machines. In smaller businesses with one or two hosts then the features can be overkill. The addition of virtual TPM support is a very nice addition to provide vm security in a more Microsoft supported methodology.

ReadWriteMany Longhorn volumes are still using NFS (file-based) protocol in the core.
Using iSCSI as main protocol instead of FC ties Longhorn to Ethernet-based LAN which is in most architectures much slower that FC-based SAN.
Longhorn could implement S3 as alternative access protocol to its volumes.
Backups, and snapshots configuration could be configured at each volume-level by administrators (maybe from additional CRD object?), because currently is configured at storage-class level which is not granular enough.
More detail in recent tasks. Instead of just showing a task called "Reconfigure virtual machine" also have a link to more detailed information as to what was reconfigured, changed or removed.

We are constantly looking for change that will benefit our company. We are not ones to stick with a product simply because it is what we know, but rather looking for what fits us best. We can't imagine another product on the market today doing a better job of handling our infrastructure than vSphere.
Longhorn is mature software defined storage solution that is still developed and receive new functionalities. From the beginning every Longhorn volume have multiple (at least two) replicas, can leverage manual or automatic snapshots and backup to external S3 volume. Longhorn provides nice and clear GUI for administrators, but also can be managed from CLI.
Very useful for environments where space and energy consumption are issues and management is not very keen on upfront spending on hardware every time whenever requirement comes from any dept for provisioning a machine for their occasional use, easily can be done in case of VMware vSphere in few clicks. Backup, security, monitoring and management everything is covered but at additional cost.

I rarely ever have to contact support and when I do need to resolve an issue, there is always an abundance of kb articles and research information available that can help quickly resolve the issue. Depending on the type of support contract you have, you may get support from some offshore group in another country and this could be a little challenging because of the language barrier.

Just make sure that when you implement, that the person implementing truly knows what they are doing and has a plan of action coming in. Since our initial implementation using a consulting service, I have implemented a few vSphere just from what I learned at the initial implementation and use over time, and the person implementing really needs to know what they are doing or you will miss out on features that may help you down the line
GlusterFS was first Persistent Storage solution used in our Kubernetes-based clusters. It is file-based what in some usages led us to many data corruptions. CEPH is object-based persistent storage which can be used as file-based Persistent Storage in Kubernetes. It is also is much more resource-hungry than other solutions including Longhorn. Dell PowerScale (or Isilon) is a hardware-software solution, that provides volumes that can be accessed by file-based NFS and CIFS protocols. Recently was added access to its volumes with object-based S3 protocol. Longhorn is in the middle. It is block-based, it is build on industry standards like iSCSI, performs very well on 10Gbit or faster LAN and commodity hardware (or in virtual machines)
vSphere has a lot more feature sets than Hyper-V but at a much higher cost of entry versus MS Hyper-V. I have not been able to play with Hyper-V as much as I would have liked, but the setup and ongoing maintenance seems to be easier in vSphere than with Hyper-V

The contract terms are very clear and can be updated as per the project requirement. Customer support is also included in the contract which help us to troubleshoot critical issues very easily. Training included in contract will really help the client team to empower and hands-on on the latest updates and enhancements
As I said earlier, they're always ready to understand our issues and propose the best and most appropriate solution for issues all the time. The security patches solution is accordingly to the business needs. Another scenario is their Knowledge Base where they're many articles that help you in order to solve something which is wrong.

Having vSphere helped my business quickly recover from a ransomware attack which would have crippled us for weeks if we were not virtualized. I think the ROI on something like that is immeasurable.
vSphere has allowed my company to purchase bigger server hardware to host 3 or 4 virtual servers, which was at a cost much lower than buying 3 or 4 server hardware boxes, saving us thousands each time we need to upgrade hardware.
