OpenStack Advantages vs VMware ESXi
When considering migration from existing VMware infrastructure, there’s lots of things to factor on advantages of OpenStack over VMware ESXi. The concept of replacing a large scale proven platform such as VMware with an open source design used to be an idea that was laughable at one time, but no longer.
This is because the two are in fact very different in design and theory. VMware often uses the term stateless compute node to describe the ESXi system.
By using a virtual VMkernel to load the proper agents and required software, admins can manage and oversee through the console and even install remotely through an approved hardware list.
Enterprise level services and a specific ability to adapt to the problem at hand, VMWare is largely implemented as ways to address corporate process problems.
Effective and efficient in small scale applications, this kind of infrastructure base can lead to problems growing. Many of the processes from VMWare were never intended for cloud use and thus not meant to scale along with the company or employee growth.
If you are using the bare metal hypervisor as an integral part of your network operations, there’s a lot of differences between EsXi and OpenStack. For reasons that should be very clear, using the VMware vSphere Hypervisor is nothing at all to what OpenStack offers.
Not being able to communicate back to the vCenter server, the functionality behind the free hypervisor are just a service compared to the robust OpenStack source.
OpenStack is a ground up approach that allows for true scalable growth without being restricted by legacy footwork. Implementing a true uniform infrastructure that makes for a scalable solution in logical blocks of data isolates the applications from having to do the heavy lifting.
Flexible horizontally as well as vertically, this kind of groundwork allows for high stream efficient management of resources that are used by parts of your network that need it. Regardless of what the day to day workstream calls for, the infrastructure is ready to compute and process data at an exponential rate.
So what is the difference between OpenStack and VMware ESXi? It really comes down to what you need and why you need it. When you need to address an issue internal to corporate growth that’s application or problem specific, VMware is still your best bet.
If an enterprise level change in approaching your network mindset is required, OpenStack is a popular option. So popular in fact that it’s making up ground between the much larger framework players like IBM, VMWare and more.
With the new approach to network management, OpenStack is far different than the past. The open source nature eliminates the bulky nature of end user agreements and streamlines your corporate workflow.
I’m not normally one to comment, but I have an interest in both vmware and openstack.
This article is so vague and blaze, that I have no real idea what you are trying to say. You need a few “actual” examples when you say stuff. It’s all so high level that I doubt anyone will really understand your points. I certainly don’t.
Perhaps this is just aimed at some highly intellectual subset, of system architects, of people interested in OpenStack and VMware, who are into IT and who like reading articles. Which I calculate as about 8 people worldwide. enjoy
Hi, Id certainly like to vouch for what JK has said ablove. To me personally this article dint provide any advantages or for that matter disadvantages of using one over the other. Very vague.
(Disclaimer: I work for VMware’s networking and security group, which helped to kickstart the OpenStack Neutron project.)
Hi, this type of vague and unclear comparison between VMware vSphere (a hypervisor) and OpenStack (a cloud management platform) doesn’t help anyone. You can’t make direct comparisons between vSphere and OpenStack. Why? OpenStack *isn’t* a hypervisor. OpenStack *needs* a hypervisor. Sometimes that hypervisor is KVM, but sometimes that hypervisor is…gasp…vSphere! Yes, VMware vSphere is fully supported running under OpenStack. Is vSphere the right choice for all workloads deployed on OpenStack? That would be a far more productive discussion to have than presenting an incorrect and inaccurate comparison between two products from two different product categories, IMHO.
Thanks for your feedback on this article. I agree with you completely that the content of this article is vague and not very helpful. This article (and a couple other OpenStack ones) were actually guest posts that were contributed by someone else. Would any of you be interested in revising this article to make it better?
I suspect the author knows nothing of OpenStack or VMWare
Could you explain the relationship between OpenStack and open virtualization format (OVF)?
