What is VMware: Everything You Need to Know

VMware Introduction

Today, VMware’s virtualization products are considered to be an essential component of many enterprises’ IT environments. VMware develops virtualization software.

 

Virtualization software overlays a computer hardware and enables the hardware components of a single computer, including the processors, memory, storage, and others, to be partitioned into multiple virtual computers known as virtual machines. Every virtual machine has its own OS and functions as a separate computer while in fact it is a part of the real underlying physical computer. VMware courses , VMware training , VMware learning are famous among multi national companies.

 

As you can well understand, virtualization helps to use computer hardware more effectively and allows to get more value from the hardware investments of an organization. It also allows cloud providers—whether public or private—to host more users with the same physical computer hardware.

 

Virtual machines (VMs): 

 

A virtual machine is the smallest component of VMware virtualization. A VM is a virtual version of a real computer and is implemented using software. An operating system that is hosted in a VM is referred to as the guest operating system.

 

Every VM has a configuration file that contains setting of the VM, a virtual disk file which is a virtual copy of a hard disk, and a log file that records the activity of the VM including system crashes, changes in the hardware, migration of the VMs from one host to another, and the state of the VM.

 

There are several products from VMware that can be used to work with these files. Virtual machine settings can be set from the vSphere Client which is a form of command-line interface for managing virtual machines. You can also configure VMs using other programs by using the vSphere Web Services software development kit. For instance, you could allow your software development environment to create a virtual machine which the environment could use to test a software program.

 

What is VMware Workstation?

To recap, VMware Workstation has a Type 2 hypervisor implementation. While a Type 1 hypervisor eliminates the underlying OS and presents a virtual environment directly to the user, a Type 2 hypervisor is installed as an application on the desktop OS and allows the desktop user to run another OS on top of the main (host) OS.

 

VMware Workstation is available in two editions: 

 

●    There is a free version known as Workstation Player and this version is only limited to hosting a single guest OS.
●    Workstation Pro runs various guest operating systems and is interoperable with VMware’s business virtualization solutions.

 

Virtualization:

These are the different parts of VMware virtualization and how they function.

 

VMware ESX: 

The hypervisor most relevant to a data center is VMware’s ESXi, which is a Type 1 or “bare metal” hypervisor that takes the place of the first-level operating system that would otherwise interface with a computer’s hardware. It replaced ESX, which was a full hypervisor which utilized more host computer resources than vSphere. VMware has discontinued ESX.

 

How does VMware Help Organizations to Manage Applications and Operating Systems

 

VMware hypervisor: 

VMware virtualise physical computers with its primary product of a hypervisor. A hypervisor, also known as a virtual machine monitor, is a thin software layer that resides between the host computer and the guest operating systems and manages the access of the host’s resources by the guests. The guest OS asks for resources from the hypervisor.

 

The hypervisor isolates each guest OS and thus allows each of them to run independently of the others. If one guest OS has an application crash, become unresponsive, or get a virus, it will not negatively impact the other operating systems on the host.

 

Desktop virtualization: 

VMware is a reputable server based hypervisor vendor; however, it also offers products that perform desktop operating system virtualization. This section describes some of that software and how it operates.

Virtual desktop integration (VDI): 

However, VMware has provided an intermediate solution of the third type located in between the server virtualization mentioned above, VDI—the virtual desktop integration. VDI virtualizes the desktop operating system on the server.

 

VDI provides centralized management of the desktop, which allows you to manage and solve problems regarding the operating systems of the desktops without physically visiting the site or having physical access to the desktop. Clients can run their applications and access their data from any device at any location with the added bonus that they do not need to spend a lot of money on powerful client endpoints. Sensitive data secure never goes out of the server.

 

VMware Horizon: 

VMware Horizon is VMware's family of VDI tools. It supports both Windows and Linux desktop operating systems, but its core is based on Linux. Your virtual desktops may be hosted on your own premises or you may use Horizon Cloud to host them in multiple hosted cloud sites.

 

Horizon suite has Horizon Apps, a tool that allows you to build an app store for the enterprise users to operate on their virtual desktops. Your users can have a combination of on premise, cloud based and mobile applications across the organization all authenticated by one sign on.

 

VSphere: 

VMware vSphere is the enterprise virtualization software suite by VMware, which makes up of the ESXi, a type- 1 hypervisor, and the vCenter Server that is used to manage multiple hypervisors.

 

VSphere is available in three configurations: They include: Standard, Enterprise Class, and Platinum. Both have policies in storage of virtual machines, live workload migration and come with integrated security measures. The additional features for the more expensive packages are such as Virtual Machine level encryption, Container integration and management, Load balancing and centralized network. Platinum alone can generate automatic responses to security threats and compatibility with other security operations tools.

 

What is VMware vSphere and How Does it Help in Virtualization

 

VCenter: 

VSphere has many components, and one of them is vCenter Server. This is the management part of the vSphere. It enables you to perform the administration of virtual machine installations in a large pool of host servers. It configures virtual machines to hosts, assigns resources for virtual machines, and measures resource utilization in hosts. As for user privileges, they can be managed using this tool according to the user’s own policies.

 

VMware's SDDC elements consists: 

 

1. VMware NSX

VMware NSX is a type of network virtualization product which lets you create and manage your IT network topologically in software. Some of the network capabilities like switching, routing, traffic load balancing, and firewalls can also be integrated and implemented on hypervisors that are hosted on x86 computers. Instead of having to manually set various pieces of hardware in the different interfaces, you can manage these functions in one screen and in addition, you can apply policies in software to perform network functions. Namely, the network part of VMware’s SDDC is the same as applies virtualization to networking, software, and computing functions.

 

The product supports your data center, your private cloud, and public hosted clouds, whether from the vendor or a third party. This makes it easier for your network to support cloud-native apps that run in container environments, and are made up of microservices.

 

2. VMware vSAN

VMware vSAN is one of the solutions that fall under the storage virtualization family of VMware products. This forms a software interface between the Virtual Machines and the physical storage devices. This software is within the ESXi hypervisor family and presents the storage devices as a single storage pool that is shareable by machines in that cluster.

 

With VMware vSAN, your VMs can utilize storage of any computer in the cluster instead of the specific computer which might get exhausted of storage space. It also saves the physical computer’s disk space if the VMs hosting on the specific physical computer do not consume the disk space. Other hosts on which run VMs may also use this storage.

 

VSAN works with vSphere to form a storage pool for management tasks that include, HA, workload migration, and workload balancing. The custom policies allow you to have precise control on how vSphere utilizes the shared storage.

 

3. VMware Cloud

Under the VMware Cloud brand, VMware delivers several products and services. VMware Cloud Foundation is a software suite that supports hybrid cloud management that consist of a number of services for software defined compute, storage, networking and security which is hosted as a service from multiple cloud providers. It is possible to run it in a private cloud using vSAN ReadyNode – an instance of the server implementation certified by an OEM cooperating with VMware.

 

4. VMware HCX (Service)

VMware HCX is one of the modules of VMware Cloud which assist organizations in leveraging a combination of environments. This gives IT teams the functionality they want at the right cost and allows IT to store more proprietary data on the systems. The issue arises in integrating these VMs to function in these different environments.

 

HCX is what VMware has to offer in this regard of the emerging hybrid cloud environment. It is a SaaS product that allows one to centrally manage many vSphere environments running across private data centers as well as hosted cloud environments.

 

Benefits of VMware:

 

Virtualization with VMware products and services is beneficial in the following ways. These include the following:

 

●    Improved return on investment (ROI): With VMware you can utilize more of a physical computer’s resources. Managers do not prefer to implement many mission-critical applications on a single server OS because if an application fails, it brings instability to the OS and the other applications also fail. The only way of avoiding this risk is to have each application running in its own OS on its own physical server, but this is not efficient mainly because each OS would only be utilizing about 30% of a server’s CPU capacity. In VMware, each application is run on its own OS on the same physical server and the physical server is utilized optimally in terms of CPU usage.

 

●    More efficient use of energy and space: VMware allows you to support more applications with fewer numbers of physical servers. Less physical servers mean that they occupy less space in your data center and less power is needed to power and cool them.

 

●    Industry support: Today, VMware is the world’s leading supplier of virtualization solutions for business, cooperating with more than 500,000 clients. There are 75,000 partners to assist customers with a broad range of optional products and services.
