OpenStack and VMware: Hardware and Architecture

When it comes to virtualization software, vSphere holds a prominent position. The product suite incorporates VMware’s ESXi hypervisor, vCenter Server, and an HTML5-based interface among other key components.

Understanding OpenStack

Unlike vSphere, OpenStack isn’t just a single product. It’s a comprehensive collection of open-source software that allows creation and management of both public and private cloud infrastructures.

It consists of extensive compute, storage, networking, content delivery, security, and analytics resources. Essentially, OpenStack functions as a cloud operating system capable of organizing and provisioning large resource pools.

vSphere vs. OpenStack: A Comparison

Deciding between vSphere and OpenStack necessitates an in-depth comparison of features and capabilities. Your choice should be guided by whether you need a primarily cloud or virtualized environment.

If your organization already uses VMware, extending your VMware facility to support cloud bursting might be beneficial. It offers business continuity while still enabling access to the cloud’s advantages.

Yet before you leap into integrating cloud automation in your IT processes, ensure you comprehend how to induce cloud bursting fully.

Examining Storage Handling Methods

Likewise, each platform uses different methods for handling storage, backup, and disaster recovery. vSphere maps storage to ESXi wherein each ESXi host accesses its storage through a logical unit number mapped to a data store.

OpenStack environments require persistent block storage which calls for external storage supporting OpenStack’s Cinder API. However, OpenStack comes with the direct object storage absent in VMware vSphere.

The cost implications of these two platforms differ with OpenStack generally reducing storage infrastructure costs but potentially increasing management costs. With vSphere, you might experience the opposite. Make your choice keeping in mind your organization’s resource allocation and priorities.

Comparing Costs: OpenStack VS VMware

Many IT professionals express concern over VMware’s acquisition, primarily from Broadcom and VMware customers.
