Introduction : VMware Infrastructure Introduction

VMware Infrastructure Introduction
VMware Infrastructure is a full infrastructure virtualization suite that provides comprehensive virtualization, management, resource optimization, application availability, and operational automation capabilities in an integrated offering. VMware Infrastructure virtualizes and aggregates the underlying physical hardware resources across multiple systems and provides pools of virtual resources to datacenter in the virtual environment.
In addition, VMware Infrastructure brings about a set of distributed services that enables fine-grain, policy-driven resource allocation, high availability, and consolidated backup of the entire virtual datacenter. These distributed services enable an IT organization to establish and meet their production Service Level Agreements with their customers in a cost effective manner.
The relationships among the various components of the VMware Infrastructure are shown in Figure 1-1.

VMware Infrastructure includes the following components shown in Figure 1-1:
VMware ESX Server A robust, production-proven virtualization layer run on physical servers that abstracts processor, memory, storage, and networking resources into multiple virtual machines.
VirtualCenter Management Server (VirtualCenter Server) The central point for configuring, provisioning, and managing virtualized IT environments.
Virtual Infrastructure Client (VI Client) An interface that allows users to connect remotely to the VirtualCenter Server or individual ESX Servers from any Windows PC.
Virtual Infrastructure Web Access (VI Web Access) A Web interface that allows virtual machine management and access to remote consoles.
VMware Virtual Machine File System (VMFS) A high-performance cluster file system for ESX Server virtual machines.
VMware Virtual Symmetric Multi-Processing (SMP) Feature that enables a single virtual machine to use multiple physical processors simultaneously.
VMware VMotion Feature that enables the live migration of running virtual machines from one physical server to another with zero down time, continuous service availability, and complete transaction integrity.
VMware HA Feature that provides easy-to-use, cost-effective high availability for applications running in virtual machines. In the event of server failure, affected virtual machines are automatically restarted on other production servers that have spare capacity.
VMware Distributed Resource Scheduler (DRS) Feature that allocates and balances computing capacity dynamically across collections of hardware resources for virtual machines.
VMware Consolidated Backup (Consolidated Backup) Feature that provides an easy-to-use, centralized facility for agent-free backup of virtual machines. It simplifies backup administration and reduces the load on ESX Servers.
VMware Infrastructure SDK Feature that provides a standard interface for VMware and third-party solutions to access the VMware Infrastructure.
