Difference between VMware ESX and ESXi
VMware ESX
ESX (Elastic Sky X) is the VMware’s enterprise server virtualization platform. In ESX, VMkernel is the virtualization kernel which is managed by a console operating system which is also called as Service console. Which is linux based and its main purpose is it to provide a Management interface for the host and lot of management agents and other thrid party software agents are installed on the service console to provide the functionalists like hardware management and monitoring of ESX hypervisor.
ESXi (Elastic sky X Integrated) is also the VMware’s enterprise server virtualization platform. In ESXi, Service console is removed. All the VMware related agents and third party agents such as management and monitoring agents can also run directly on the VMkernel. ESXi is ultra-thin architecture which is highly reliable and its small code-base allows it to be more secure with less codes to patch. ESXi uses Direct Console User Interface (DCUI) instead of a service console to perform management of ESXi server. ESXi installation will happen very quickly as compared to ESX installation.
Comparing the Legacy and New vSphere Architectures
Improve Reliability and Security -
The ESX architecture available in releases prior to vSphere 5.0 relied
on a Linux-based COS for serviceability and agent-based partner
integration. In the new, operating-system independent ESXi architecture,
the approximately 2GB COS has been removed and the necessary management
functionality has been implemented directly in the core VMkernel.
Eliminating the COS drastically reduces the install footprint of the
vSphere ESXi hypervisor to approximately 150MB, improving security and
reliability by removing the security vulnerabilities associated with a
general purpose operating system.
