  The files that make up a VM are usually stored together in the same folder. Using these files, you can perform the following actions: Save the entire state of a VM to files that are encapsulated together. Copy the VM files to create multiple replicas of the VM. Move a VM from one host to another to perform routine maintenance of the physical server. Portability   one of the Challenges addressed by VM encapsulation 

  vSphere Client    is the nice looking web interface GUI for managing both vCenter and Exsi host. Keyword ( vCenter and Exsi host ) , on the same interface you also manage the virtual switch, datastore and  Vms. vSphere client used to be a desktop client app with version 6.0 and earlier, version 6.0U2 the client was fully web based HTML5 and the url to access the client is :   https://vcenter_server_ip_address_or_fqdn/ui VMware Host Client   is also a HTML5web based client that used to manage a single host, Keyword ( Single host management ) , multiple host management use the vSphere client and you cannot manage the vcenter server using the VMware host client. this client also manages the Vms, network and storage, access the host client using this url  :  http://host_name_or_host_IP_address/ui vCenter Server management interface abbreviated as ( VAMI ) , is a administrative tool for the vcenter server ( VCSA ). some basic administrativ...

  Challenge that VM hardware independence addresses:      Compatibility You can move any VM to any physical server, without having to worry about the compatibility of the VM with the underlying hardware. Virtualization provides a guest operating system with the virtual hardware that it requires. If you need to use an OS that requires specific hardware,  VM can be provisioned with standardized software-based hardware. But. Above is a clarification just incase you were planning to use Vmotion to failover virtual machine from one Hardware that has an Intel CPU to another hardware that has an AMD CPU. here is the link to the full thread you can read more.

  Challenge that server consolidation addresses: Costs Consolidation helps with cost by not buying more server to install each operating system ( Windows, Linux, Windows 10, Windows server 2012 ) , just buy one server with lots of Memory and CPU and have more that 200 operating system running in one server at the same time, sharing ( Memory, CPU, Storage and Networking ) hence saving cost. Using VMs, you can run multiple operating systems on one physical machine. In this way, you can reduce the number of physical servers and manage your virtual servers more efficiently: Reduce power, cooling, and maintenance costs Create time to focus on innovation Increase the efficient utilization of resources
