Hello Readers!
We will start by understanding few points about VMware Organisation & its products
--> VMware is the market leader in server virtualization
--> It has about 85% of market share, better than XenServer & Hyper-V due to stability and flexible usage.
--> Hypervisor from VMware is called ESX/ESXi
{Elastic Sky-X, this naming itself suggest unlimited scalability}
Difference between ESX & ESXi:
ESX:
* Named as Elastic Sky - X, had larger footprints when compared to ESXi
* It has been discontinued from vCenter 5.0 onwards
* Last available version was ESX 4.1
* VMKernel is the virtualization kernel which is managed by a service console used by admins, which is linux based.
* Other management agents & 3rd party agents interacts with service console not with vmkernel directly.
* Requires more patches & updates.
* Main command -- esxcfg-
* Web console had limited options
ESXi:
* Elastic Sky - X integrated, with tiny footprints, takes few hundred MBs for installation
* This is the latest and enhanced available hypervisor from VMware
* Service console has been removed with Direct Console User Interface (DCUI)
* All management agents & 3rd party agents interacts directly with VMKernel now
* Require less patches due to smaller footprint & smaller code base.
* Main command -- esxcli
* Web Console is now enriched with full features & options
