VMware ESXi vs. VMware vCenter vs. VMware vSphere

If you're looking for the industry standard in server virtualization, I would recommend ESXi. After decades of expertise in the field, VMware continues to provide a strong product, production-ready, with an easy-to-learn interface that allows for quick management along with less costly upfront onboarding and training. Grab the free personal-use license and install in your homelab to start!

The VMware vCenter server is very useful in maintaining the CPU/RAM/datastore resources are balanced when there are multiple ESX/ESXi host servers. It is clear what resources are being used, and it is easy to migrate VMs to different ESX/ESXi hosts. Being able to remotely connect to the VM servers in vCenter when you cannot have other remote connections helps in maintenance and troubleshooting.

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.

• Resource management. The automatic load balancing works very well to ensure no host is taxed disproportionately compared to the others.
• Templates and cloning. It is very easy to set up a template and spin up new servers based on a specific setup. This makes server management very streamlined.
• VM management. The vSphere interface is very easy to use and navigate. Everything is responsive and it works when you need it to. The options are also robust while also being arranged in a straightforward manner.

Incentivized

• VSAN storage management and redundancy - high performance IO with built in fault tolerance across the cluster, not reliant on a single hardware item
• VM fault tolerance. The ability to relocate a running VM and restart VMs from failed or isolated nodes
• Resource management and alerting. Tracking load across physical systems and allowing us to rebalance for better utilisation

Incentivized

• vMotion that provides seamless movement of Virtual Machines between physical hosts and datastores.
• Ease of Manage: vCenter provides very good management experience to the users.
• It provides hassle free upgrade of versions, which requires good planning.
• Easy to manage datastore, networks, CPU and memory resources.
• It also allows to convert the physical machine and bring it to vSphere Environment with minimum effort.

Incentivized

• VMware ESXi can improve on the UI that is installed on the bare metal machine. The menus can be hard to navigate when looking for simple configuration items.
• VMware ESXi can improve on the stability of their overall hypervisor. There have been a few times we had to reinstall due to corruption of VMware ESXi.
• I would like to see VMware ESXi do better at adding more standard free features in their consumer version of VMware ESXi. For example, having the ability to back up virtual machines is good practice and something that would be very nice if offered in their free version.

Incentivized

• Currently, the HTML 5-based vSphere Client lets you manage the essential functions of vSphere from any browser, however, it would be nice if they would port all management functions over to the HTML 5-based Client.
• Performing updates and upgrades to the infrastructure is a bit challenging for someone that may not be as intimate with vSphere. I think the updates/upgrades should be more integrated into the UI and provide the ability to push to the hosts, etc...
• It would also be nice to have a more robust snapshot management tool to prevent snapshot overgrowth. It would be nice to be able to set a lifespan for the snapshot(s)

Incentivized

• Allow enable EVC without requiring host shutdown
• 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.
• Allow searching tasks or events

It is critical to our business, what started out as a way to do certain functions, it has now become core to ensuring our product is available to our customers and reducing our costs to operate and reduce our recovery time and provisioning servers. Their support is great and the costs to renew is reasonable.

Incentivized

We are very dependent on this software, it has become a much needed tool to perform the daily tasks that are required to maintain the virtual server environment. VMware has become very pricey over the years, so we are looking for alternatives for cost savings strategy, but nothing has been found to be on par to what we are currently using

Incentivized

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.

The interface is fairly intuitive for most things, and the areas that are a little less obvious usually have fantastic documentation in the online knowledgebase. In 3-4 years of managing our ESXi hosts, I think that I have only opened 4-5 support cases for things that I could not figure out myself or find answers to on the website.

I work with vCenter for 10+ years and i love it. I can find my way around and can help building and expanding the platform. It is easy to use and there are a lot good communities for the extra support when needed. Even the Homelab community is of great value.

Incentivized

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.

Incentivized

Without the need to patch the servers with bug fixes and enhancements we whave not experienced any downtime with VMware issues. Even the bug fixes and updates do not cause of downtime as we just migrate the servers to the opposite node and update the one and then move servers back. Very simple and painless.

Incentivized

We do not notice any difference between a physical and virtual server running the same workload. In fact we can scale quicker with the virtual server than we can with the physical.

I can't say enough good about VMware's support team. To an individual they take ownership of the case, provide thorough answers, and follow up regularly. On one occasion, a problem we experienced with NSX Endpoint was escalated to development for a permanent resolution after a workaround was found. In my experience, most companies would have tried to find a way to close a case like that instead of taking it all the way. Most importantly, when production is down and every second counts, they VMware teams understand that urgency and treat your issue as if it were the only one they had to deal with. You can't ask for better.

Incentivized

VMware support has always been fantastic and they have been invaluable in solving tougher issues that have been run into. Most of the time, any oddities encountered are fixed by available updates. This can be deduced by support quickly with logs within vCenter. We have not run into something yet that support was unable to help with. They either have a solution already, or they are able to find one quickly.

Incentivized

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.

Jsut read and follow anything your storage provider may require to allow the integration of VMware with storage operations, outside of that VMware jsut works.

Since moving away from the Windows Server hosting the vCenter application and instead using a virtual appliance, it has become much easier to implement and deploy the new versions. We can easily create a snapshot or clone of the vCenter vApp to ensure any problems encountered during the upgrade can be mitigated with a fall back to the old version to prevent unscheduled downtime.

Incentivized

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

As long as you're using Nutanix AOS on Nutanix hardware and are paying their software support fees, AOS is a valid competitor to VMware and can save money due to not needing a license and having their server management system built into the base host management system. If you aren't using Nutanix hardware, however, VMWare is in most cases the best way to go. I cannot comment on HyperV, but most IT people I know either use it because they have to (most) or they like it better (not many).

Citrix Xen Server.... Great Hypervisor but very limited in terms of functionality

MS Hyper-V... [VMware vCenter Server] is better for almost everything and appliance form makes a clear winner for security and ease of deployment

Incentivized

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

Incentivized

it has been fair and easy to understand. I know VMware is looking at wanting to change from CPU to core pricing so we will see what that looks like when it happens.

Incentivized

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

We started out with a two-server cluster and adding a third or fourth is very straightforward and simple with no issues. You just need to be aware of the size of your Vcenter Server to handle the workload, but still the resources needed is very minimal

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.

• VMWare ESXi licensing is affordable for our business - and the licensing model is simplistic. Not like that of Microsoft with having to keep track of server licenses and CAL licenses for users.
• VMWare ESXi also has hardware-monitoring built-in, so that further saves us money from having to be spent with another vendor.
• As much as I hate the saying "a single pane of glass" does fit for this product. You can manage your servers, monitor hardware status, create and export backup snapshots, manage virtual NICs, connect to various storage devices. We're very happy with this product.

• The positive impact of vcenter is definitely felt in larger organisations in terms of being able to manage multiple servers all in one environment
• It will decrease the amount of time your server engineers will have to spend in the server room or datacenter.

• 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.
