• Empowered IT departments with choice. VMware vSphere™ 

future- proofs IT environments while delivering business services 
on demand, with the freedom to choose the right industry 

standard hardware, application architecture, operating system, 

in-house or external infrastructure for changing business 
requirements. With VMware vSphere™ 4, customers retain flexibility 
of choice, remaining independent of hardware, operating system, 
application stack, and service providers.  This means customers can 

support their existing applications, and feel confident about future 
applications, while retaining the flexibility to deploy within internal 

or external cloud infrastructures.

Customers use VMware vSphere™ to:
Consolidate and continuously optimize server, storage and

VMware vSphere™ eliminates server sprawl by running applications 
inside virtual machines on fewer servers and with more efficient 
use of storage and network resources. Organizations using 
VMware vSphere™ can achieve the highest consolidation ratios 
per server through its unique dynamic optimization and memory 
management capabilities. VMware vSphere™ reduces the 
complexity of hardware management through comprehensive 
virtualization of server, storage and networking hardware. VMware 
vSphere™ customers can slash capital expenses per application on 
the average by at least 50 percent, and operating (labor) costs by 
over 60 percent.

VMware vSphere™ helps create a secure, unbreakable infrastructure 
that keeps businesses running despite hardware failures or even 
entire datacenter outages. VMware vSphere™ not only eliminates 
application downtime due to planned server, storage or network 
maintenance activities, but also provides simple, cost effective high 
availability against unplanned downtime such as server failures. 
VMware vSphere™ also simplifies recovery from full datacenter 
outages, without the need for expensive redundant hardware.
Streamline IT operations

The VMware vSphere™ platform simplifies operational management 

of test, development and production environments, across many 
locations, remote and branch offices and including all types of 
applications and operating systems. VMware vSphere™ allows easy 

sharing and replacement of hardware resources and simplifies 

management through common sets of policies, operational 
procedures and automated management across disparate sets of 
applications and business users.

VMware vSphere™ simplifies the provisioning of business services 
and ensures a uniform assurance of service levels regardless 
of physical infrastructure or the actual location of the services. 

This not only reduces operational overhead, but also allows 

for the portability of applications across internal or external 

cloud infrastructures without losing service levels or requiring 
customization.

VMware vSphere™ is the industry’s first cloud operating system 
comprising of the following groups of components:

Infrastructure services –  The set of components that 
comprehensively virtualize server, storage and network resources, 
aggregate them and allocate them precisely on demand to 
applications based on business priority.

Application services – The set of components that provide 

built-in service level controls to all applications running on VMware 
vSphere™, regardless of application type or operating system.

Administration of  infrastructure and application services,  

automation of day-to-day operational tasks with deep visibility into 
every aspect of large and small VMware vSphere™ environments is 
provided by VMware vCenter™ Server

VMware vSphere™ infrastructure services transform discrete 
hardware resources into a shared mainframe-like computing 
platform that is incredibly resilient and capable of running the most 
demanding applications with near-native performance.  VMware 
vSphere™ provides the following types of infrastructure services:

Infrastructure services that efficiently virtualize 

server resources and aggregate them into logical pools that can 

precisely be allocated to applications.

• VMware ESX™ and VMware ESXi provide a robust, production-

proven, high performance virtualization layer that abstracts 

server hardware resources and allow their sharing by multiple 
virtual machines. Unique memory management and advanced 
scheduling capabilities of VMware ESX and ESXi allow for the 

highest consolidation ratios and the best application performance, 
in many cases, even better than physical servers.

• VMware Distributed Resource Scheduler (DRS) aggregates 

compute resources across many clusters and dynamically 
allocates them to virtual machines based on business priorities, 
reducing management complexity through automation. VMware 

Distributed Power Management (DPM), included with VMware 
DRS, automates energy efficiency in VMware DRS clusters by 

continuously optimizing server power consumption within each 
cluster.
