In this article we have featured OpenStack vs VMware, Moving from VMware to OpenStack can significantly reduce the TCO associated with initial cloud infrastructure roll-out and ongoing maintenance.

Economic analysis of OpenStack vs VMware reveals that under certain conditions, costs can be reduced by an order of magnitude. This necessitates the selection of an OpenStack distribution that can be economically maintained. Canonical’s Charmed OpenStack is one such distribution.

We recently released a webinar and a whitepaper in which we presented the results of our cost-cutting analysis resulting from the migration from VMware to OpenStack.

You can consult those materials or simply read through this blog to get the most important information. So let’s start by highlighting the differences between OpenStack and VMware and then go into more detail about how they affect the costs associated with both.

OpenStack vs. VMware: Economics comparison

OpenStack vs VMware

VMware’s virtualization platform is available as part of the vRealize Suite. VMware owns the entire platform and its source code. vRealize is intended to run on dedicated hardware such as blade servers and storage arrays.

Its architecture is centralized, which means that control services run on their own dedicated nodes, while computing, network, and storage resources are provided by other nodes independently. VMware vRealize Suite is available in three different editions, with some services available only to those willing to pay more.

OpenStack vs VMware

OpenStack

OpenStack is a free and open-source software platform for creating private and public clouds. OpenStack is a cloud operating system that manages large pools of computing, storage, and networking resources throughout a data center via a dashboard that gives administrators control while allowing users to provision resources via a web interface.

VMware vSphere: A free bare-metal hypervisor that virtualizes servers to allow you to run more applications on less hardware.

vSphere is the most popular server virtualization platform in the world. Use VMware vSphere to build a cloud computing infrastructure with fewer servers and lower capital and operating costs.

The VMware vCloud Suite is a one-of-a-kind offering that is not modular and must be purchased in its entirety. The only default hypervisor is ESXi. Although ESXi cannot be API accessed without a license, VMware vCloud has excellent guest OS support and a large ecosystem.

However, there is no support for customizing components or services as needed – similar to the expensive web application servers that sold all-in-one features without a choice prior to the introduction of newer frameworks that are happier versions of “include per need” features that can run on standard web servers.

Operations

VMware vCloud has a well-designed graphical interface in vCenter for administrators and users to use to centrally manage virtual machines and ESXi hosts.

ESXi virtualizes servers bare-metal, whereas vCenter provides a centralized platform for managing vSphere, the replication provider, at the individual virtual machine level. By pooling virtual resources into virtual datacenters, vCloud Director enables the creation of secure, multi-tenant clouds.

Migration of virtual machines between physical hosts is supported with zero downtime via vMotion but requires shared storage such as VMFS, SAN, and shared NAS. VMware includes features such as DRS, DRM, automated monitoring of physical server availability, system health, and virtual machine restart.

Conclusion: Comparing OpenStack vs. VMware vCloud

VMware vCloud installation is a collection of components that must be downloaded, installed, and configured individually. Individual vCloud Suite products are delivered as installation packages for either Windows or Linux-based virtual appliances that can be deployed on ESXi hosts.

These include a number of components such as ESXi, vCenter Server, vCloud Director, and vSphere, all of which can be easily installed and configured by following a guided proper sequence, meeting system requirements, external dependencies, and ensuring component compatibility.

In comparison, OpenStack IaaS is delivered through a number of complementary services. Each service provides an API that allows for this integration.
