VMware is a software company that provides cloud computing and virtualization software and services. VMware does not manufacture physical servers, but rather creates software that allows servers to be virtualized.
What is VMware?
VMware is a company that provides cloud computing and virtualization software and services. Founded in 1998, VMware pioneered the technology of virtualization for x86 architecture computers.
Virtualization allows multiple virtual machines, with different operating systems, to run in isolation on the same physical server. This enables more efficient use of computing resources.
Some key VMware products include:
- VMware vSphere: The virtualization platform that allows users to create and run virtual machines. vSphere includes features like live migration that let you move VMs between hosts.
- VMware NSX: Network virtualization and security software for data centers. Creates software-defined networks.
- VMware vSAN: Software that pools locally-attached disk drives across multiple physical servers to create shared storage.
- VMware Cloud: A cloud computing service that lets companies run applications across vSphere cloud environments.
So in summary – VMware focuses exclusively on virtualization software and services. It allows users to virtualize and manage servers and other computing resources efficiently through its robust ecosystem of products.
Is VMware a physical server?
No, VMware does not manufacture any physical servers or hardware. Rather, VMware software is designed to run on industry-standard x86 servers from vendors like Dell, HPE, Cisco, and others.
For example, the VMware vSphere product needs to be installed on a compatible x86 server to function. VMware relies on server hardware partners to supply the underlying physical computing power, and then their software layers on top to enable efficient utilization through virtual machines.
Some reasons why VMware is not a server include:
- VMware is a software company. Their business model focuses entirely around selling software licenses and services around virtualization.
- It doesn’t design or build physical servers. VMware has no hardware manufacturing capabilities or infrastructure.
- VMware software runs ON servers to virtualize them. vSphere and other platforms need certified server models from partners.
So while VMware software requires servers to run on, the company does not manufacture or sell them directly. The solution is agnostic to the underlying server hardware.
What are the benefits of VMware software?
There are many key benefits to using VMware’s industry-leading virtualization platforms like vSphere for your computing environment:
- Allows multiple VMs and workloads to run on the same physical server hardware.
- Balances resources dynamically between VMs based on demand.
- Rightsizes computing capacity through virtual resources.
- Features like vMotion allow live migration of VMs across hosts with no downtime.
- Protect against hardware failures through quick VM restarts on functioning hosts.
- Scale capacity up or down easily through adding or reducing VM resources.
- Virtualized resources can be provisioned in minutes compared to physical hardware.
- Isolate and encapsulate risks by running apps and software within VMs.
- Use network security policies between VMs with solutions like NSX.
- Keep sensitive systems separated on the same infrastructure.
- Increased utilization through virtual consolidation reduces hardware expenses.
- Reduces operational overheads for IT teams managing physical infrastructure.
- Optimizes capacity planning through fine-grained VM allocation.
By leveraging VMware’s innovative software for virtual infrastructure, companies gain immense flexibility, efficiency, and cost savings. The virtualization and cloud solutions provide strategic benefits for any IT environment.
Common uses of VMware software
VMware virtualization solutions share hardware resources in an optimal way so businesses can consolidate applications and workloads efficiently.
Some common uses of VMware software include:
- Combine many physical servers onto fewer high-capacity host servers.
- Use fewer physical CPU/RAM resources through shared virtual allocation.
Data Center Modernization
- Transition legacy apps from outdated hardware into virtual machines.
- Facilitate data center expansion, contraction or migration initiatives.
- Build scalable private and hybrid cloud environments with containers and VMs.
- Migrate workloads between cloud platforms and on-prem infrastructure.
- Manage desktop images efficiently using shared pooled resources.
- Deliver persistent or non-persistent virtual desktops.
Testing & Development
- Quickly spin up disposable sandbox testing environments.
- Develop across various operating systems and machine configurations.
- Replicate VMs offsite for operational continuity during outages.
- Support faster VM recovery through backup storage integration.
This provides a glimpse into why VMware virtualization is a versatile solution for optimizing resource utilization across on-prem data centers and the cloud.
Is VMware built on Linux?
No, VMware hypervisors and infrastructure software are not built on top of Linux. Instead, VMware actually provides virtualization support and management across Linux guest operating systems.
For example, VMware vSphere lets you create and run Red Hat Enterprise Linux, Ubuntu, SUSE Linux and other Linux distributions as guest VMs on the virtual infrastructure. Admins can then deploy Linux VMs alongside Windows and implement advanced clustering for resilience.
The bare-metal VMware ESXi Type 1 hypervisor runs directly on server hardware, not on top of a Linux OS. ESXi is purpose-built for speed and efficiency in managing VM resources.
By natively handling Linux-to-metal, VMware infrastructure delivers excellent compatibility to onboard Linux platforms into business environments. IT teams gain centralized visibility and control across heterogeneous OS deployments from a unified management layer.
So in summary:
- VMware software runs ON hardware, not ON Linux
- The ESXi hypervisor manages Linux guest VMs
- Allows Linux consolidation with other operating systems
- Streamlines Linux administration at scale
This Linux support, without needing its own Linux foundation, is what gives VMware platforms strategic value for unified IT infrastructure management.
What is the difference between VMware and virtualization?
It’s important to distinguish between VMware and the wider field of virtualization:
- Virtualization – The broad computing technique of creating virtual versions of IT resources like servers, storage and networks. Allows sharing physical infrastructure.
- VMware – A specific company focused on providing enterprise-grade virtualization software tools and services. A key innovator in commercializing x86 virtualization.
In other words, virtualization is the overall practice while VMware is a vendor implementation.
Hypervisor software creates and runs virtual machines (VMs) that emulate computer hardware for guest operating systems to run upon. This is the virtualization layer.
VMware develops robust Type-1 hypervisor technology powering solutions like vSphere and vCenter Server. These comprise a management ecosystem to operate production environments of virtualized servers.
Competing products like Microsoft Hyper-V or open-source KVM also provide alternative hypervisor and infrastructure platforms.
But with advanced capabilities like vMotion, High Availability, DRS clustering and Distributed Switch – VMware enterprises customers enjoy substantial efficiency, resilience, automation benefits unrivaled in analogous solutions.
So while Gartner estimates VMware commands 80% market share – virtualization itself remains an open playing field sought through multiple vectors.
Think virtualization for the concept, VMware for the dominant industry product.
