These days there are a lot of questions about VMware's virtualization solutions. In the industry, VMware is undoubtedly the premier virtualization solution provider. People who are new to VMware's virtualization platform often get confused while learning about VMware vSphere and its components. So, I will give a comprehensive introduction to them here today. It is difficult for people to understand the major components of vSphere. And it is very essential to go through the differences between vSphere, ESXi and vCenter. To learn more about vSphere, you can install a vSphere in VMware Workstation.
VMware Inc. has developed many product suites, especially in the area of providing different virtualization solutions. These include many cloud products, datacenter products, and desktop products, to name a few.
vSphere is a software suite that is part of the datacenter products. vSphere is like the Microsoft Office suite that has a lot of products like Office, Excel, etc. vSphere also includes a lot of software components like vCenter, ESXi, vSphere client, and so on. So the collection of these software is called vSphere. vSphere is not a kind of software that you can install and use, it is just a collection of software suites.
ESXi, vSphere client, and vCenter are all parts of vSphere. the ESXi server is the most important part. ESXi is a virtualization server. He is a class of virtualization manager (type 1 hypervisor). All virtual machines or client operating systems are installed on the ESXi server. vSphere client or vCenter are other parts of vSphere that you might need. vSphere client allows administrators to connect to the ESXi server through the vSphere client to access or manage virtual machines. vSphere client is used to connect to ESXi from the client machine to perform tasks. So, the question now is, what is vCenter? Why do we need it? We could have cloned the VMs through the vSphere client without the need for a vCenter server.
The vCenter server is similar to the vSphere client, but it's a more powerful server. vCenter server can be installed on Linux or Window. vMware vCenter server is a centralized management application that manages virtual machines and ESXi servers. A vSphere client can manage multiple ESXi servers by accessing the vCenter server. vCenter server has many enterprise-class features, such as vMotion, VMware High Availability, VMware Update Manager, and VMware Distributed Resource Scheduler (DRS). For example, you can easily use vCenter server to clone an existing virtual machine. So vCenter is an important part of the vSphere suite. You must purchase a separate license for vCenter.
The diagram above shows the vSphere suite more graphically. vSphere is the product suite and ESXi is the manager installed on the physical machine. vSphere Client is installed on a laptop or desktop PC and is used to access the ESXi server for virtual machine creation and management. vCenter server is installed on top of ESXi like a virtual machine. vCenter Server is installed on top of ESXi like a virtual machine. Installed on top of ESXi. vCenter server can also be installed in different standalone physical servers, but why not for virtualization? With multiple ESXi servers and dozens of virtual machines, vCenter server is used more frequently. For management in small environments, it is common to use a vSphere client to connect directly to the ESXi servers.
