Kernel-based Virtual Machine (KVM) vs. Nutanix Cloud Infrastructure

Kernel-based Virtual Machine is very well suited when one needs a single-node virtualization host or needs to build a complex demo setting on their own notebook (e.g. when demonstrating solutions to a customer).

For an organization that requires top-notch performance HCI, Nutanix is the best. You may start with 3 nodes and expand the cluster as required. The management through Nutanix Prism Central and Element was so easy that even a Junior Engineer was able to handle it. The Nutanix platform is not suitable for organizations with a small budget and fewer requirements for high-performance infrastructure, as the Nutanix solution itself is suited for enterprises.

• Lightweight built-in implementation for all *nix based OS.
• Easy to deploy and manage VMs.
• Freeware (is you are using a free OS).

• "Nutanix is an operating system playing inside an existing, rich IT ecosystem." Listen to Wendy M. Pfeiffer, CIO of Nutanix, as she shares game-changing results with the implementation of infrastructure-as-code.
• With one-click simplicity, Nutanix AOS streamlines IT operations and relieves budget pressures by integrating storage, networking, and compute services into a single solution managed by IT generalists. Start small and scale without limit to meet business demands.
• Deliver applications with the highest possible performance throughout the full lifecycle, not just day one. Provide reliable performance SLAs without worrying about workload changes or growth in application demands.

• KVM itself doesn't ship with a management interface
• KVM itself is a bit complicated to handle
• KVM needs Qemu to virtualize Windows guests

• Can be priced high at times.
• The one downside I have working with Nutanix is the sales team. They seem to try to add in extra goodies to sales quotes or push for extras that you don't really need and you have to tell them to take them out. Don't be afraid to push back on them.
• Need to analyze sizing with sales team to ensure right sizing.

AOS definitely make our dev/test virtual environment management much easier than before. And the consolidation the test/dev environment from Azure and Cisco UCS, we have less need to transfer large amount of data between different hardware platforms which was very big challenge. To expand the capacity is very easy to archive as well.

It does the job and stays out of the way. The specifics of usability relies on the implementation, but with things like Icarus and libvirt, things are standardizing nicely.

It's not out of the box easy, but once you get the fundamentals the steep learning curve flattens out and the processes to get things done and how it works becomes very apparent. It's wrapping the slight change in workflow from prior VM management methods took time to unbox and apply the Nutanix Cloud Infrastructure way

We have not had any Nutanix availability issues over the years.

Nutanix AOS performance is light years ahead of HPE. We were nervous about using Nutanix AHV but it has been a vast improvement and saves on cost. Applications has been much improved and end users have commented. It has also freed up time for our Network Administrators and made their lives easier.

Nutanix provide top tier support - their only rival in this field in my experience is Rubrik. Their sales and the aftersales team really put the effort in to make the initial install an easy process to complete and support we've required post that has been expertly handled. Their support's first point of contact is the equivalent of 3rd line at other vendors and they're always more than willing to explain concepts to help us better understand the issue/solution provided.

We requested more training than typical which was very in depth

A lot of online training courses, most of them are free.

IPv6 is needed for link local discovery. We do not have IPv6 configured on our network so the easiest way to get our nodes configured and discovered by foundation was to configure the IPv4 addressing within the node prior to trying to discover with foundation.

The key points why I made my decision for KVM in comparison with VMWare are: Freeware software (I am using an Ubuntu server OS), Fewer resources usage, vSwitch using that provides the ability to configure dot1q trunks to/between VMs, Stability, and simplicity of using/troubleshooting, Well-known interface (for Linux geeks).

vSAN on VXrail and a Cisco Flashstack was our two existing systems before bringing in a Nutanix cluster. The performance of Nutanix HCI was far better than vSAN's performance (hybrid vs. hybrid and AF vs. AF.) However, Pure does deliver on its claim of being the fastest storage possible, which is true. However, the flashstacks management and complex setup do not compare to the ease of using Nutanix HCI.

Can add on new cluster and join it to existing cluster

• Capital expenditure costs are low, because is open-source and free
• Operational expenditure costs are medium because it's necessary [to have] an IT team with experience in Linux
• First step to the virtualization world. Wake up, we are in the 21st century

• Found an immediate reclamation of time. SAN's are a pain to manage and update - Nutanix made turned a couple hours of work into one click.
• They are a software company. Every Time they come out with an update I find my performance improving, or a new feature added. Soon I'll be able to give my developers controlled self-service capabilities. I originally bought hardware and it's evolving on me into a private cloud in a box.
