The difference between vmwarevsphere and vmwareworkstation

1. Both are virtualized things. What is the essential difference between the two?

1. VMware Workstation is a virtualization tool for OS-based virtual OS resources. It can make full use of idle OS resources. If your OS machine is good enough, you can create DNS, DHCP, Apache and many other servers through VMware Workstation. Running multiple services on one machine saves a lot of expenses. This effect is a common feature of virtualization.

2. VMware vSphere is a virtualization solution that includes many things. Its core is ESXi. ESXi is an operating system independently installed on the bare metal (note that it is not based on any OS, it is an OS itself), through which the hardware resources of the physical machine are virtualized. Turn it into a virtual resource, and then through vCenter (management), you can integrate the resources of the physical machine with the ESXi operating system installed into a general resource pool. In this resource pool, we divide resources of different sizes for each department The pool is convenient for its use.

3. VMware Workstation is an OS-based software, while VMware vSphere is a virtualization solution designed according to the actual situation of the enterprise. The software, technology and issues to be considered in its design are more detailed and specific than VMware Workstation. .

4. Summary
   VMware Workstation is an OS-based virtualization software
   VMware vSphere is a specific virtualization solution

5. simply put. VMware runs on the operating system. For example, your computer needs to be installed with xp or win7 or server2003.server2008 and other systems, and then install the VMware system. The esxi virtual machine is a system that can run directly on the hardware without installing a Windows system on a computer. Generally, ESXI systems are running in IDC now.

6. The first is the difference between vSphere, ESXi and vCenter.
   ESXi, vSphere client and vCeneter are all components of vSphere. ESXi is the most important component in vSphere.
   ESXi is a virtualization service. All virtual machines are running on the ESXi service. In order to install, manage and access these virtual machines, you need another vSphere package, namely the vSphere client or vCenter.
   The vSphere client allows administrators to access ESXi services and manage virtual machines. The vSphere client is installed on the client machine (that is, the administrator's laptop). The vSphere client is used to connect to the ESXi server and manage tasks. So what is vCenter? Why virtualize it? Try to clone an existing virtual machine with only vSphere client when there is no vCenter server.
   vCenter serverSimilar to vSphere client, but more powerful. vCenter server is installed in Windows server or Linux server. VMware vCenter server is a centralized management application. You can manage all virtual machines and ESXi physical machines through it. The vSphere client can manage EXSi servers by accessing vCenter Server. vCenter server is an enterprise-level product with many enterprise-level features, such as vMotion, VMware High Availability, VMware Update Manager and VMware Distributed Resource Scheduler (DRS). You can easily clone existing virtual machines through vCenter server. Therefore, vCenter is also an important part of the vSphere suite. You need to purchase vCenter license separately.

The diagram above shows a typical virtualization deployment.

1. vmware vsphere version.
   Vmware is mainly divided into basic version, standard version, enterprise version, enterprise enhanced version and gold version, you can refer to https://www.vmware.com/products/vsphere.html, https://www.vmware.com/content/ dam/digitalmarketing/vmware/en/pdf/vsphere/vmw-flyr-compare vsphere editions-uslet.pdf.

2. vmware vsphere OEM.
   In addition to the standard version division, vsphere also cooperates with major hardware manufacturers to provide OEM versions due to the need for automated remote management, such as Cisco, Dell, and HPE (same as software for CPU architecture customization). Their cores are the same, but they have their own For defined extensions, please refer to https://blogs.vmware.com/vsphere/2017/05/apply-latest-vmware-esxi-security-patches-oem-custom-images-visualize-differences.html.

3. vmware ESXi installation.
   Generally speaking, vmwarevsphere is installed as the underlying operating system, which is different from vmware workstation. But if you need to learn, you can also download the general version and install it in vmware workstation, because ESXi itself is a Linux operating system.
