Difference between AS WS ES and Desktop of Redhat Enterprise linux

here are two Redhat Linux product line, one is free Fedora Core series is mainly used for the desktop version, providing more support for new features. Another product line is the charge Enterprise series, this series is divided into: AS / ES / WS and other branches, they are redhat Enterprise Linux , RHEL for short

AS

Is a super-server version (Advanced Server), Linux kernel in his standard, based on the performance enhancements made, and improved reliability, integrated drivers for many common server. Can easily identify the IBM / DELL / HP rack servers and other common devices such as disk array cards.

AS typical applications are:

1. Databases and database applications

2.WEB and middleware

3.CRM, ERP, SCM

ES

Enterprise server (Enterprise Server), AS the streamlining version. He often is the difference between AS series, AS support to more than 4 CPU, while the ES can only support two CPU. AS and ES in the majority there is no difference on the package, only a small number of packages in the kernel, and so there are differences. AS and ES relatively large difference between the selling price, usually used in the ES together with the server version of purchase such as buying OEM DELL server with the Linux will be the ES series. If you want to with the AS series, you need to spend several thousand dollars.

Typical applications for the ES:

1. Company WEB structure

2. Network edge applications (DHCP, DNS, firewall, etc.)

3. E-mail and file / print services

4. Small and medium-scale database and application software sector

Is the Workstation service version (Workstation Server), ES further simplified version of the main office for enterprise desktop market, the domestic small desktop application using WS is the best environment. It contains a variety of commonly used desktop applications (Office tools, email, instant messaging, browser, etc.), can run a variety of client - server configuration tool, software development tools and various software applications (such as EDA and Oil / Gas Applications , but it does not provide network services (such as DNS and DHCP), it is only suitable for the client application.

AS, ES functionally no different, whether x86, or Itanium version, RHEL's exactly the same after the three disc, that is, exactly the same package. The first disc is actually no packages, just enable the installer to determine the installation package only, but in the service level, the number of supported CPU and memory numbers are different.

Red Hat Enterprise Linux WSRed Hat Enterprise Linux WS (“workstation”) is the highend
desktop/client

member of the Red Hat Enterprise Linux family.
Red Hat Enterprise Linux WS supports 12
CPU 32bit
and 64bit
Intel and
AMD systems (x86, EM64T, Itanium2, and AMD64), and is ideal for “power
user,” software development, and technical applications such as
virtualization/rendering (CAD/CAM, EDA, etc.). It includes a full suite of
desktop productivity applications for tasks such as document creation, email,
instant messaging, and web browsing.
While Red Hat Enterprise Linux WS is based on the same software core as
the server products, it does not include a number of network server
applications (such as DNS and DHCP). Therefore it is suitable only for use in
client environments. Enterprise Linux WS is available with Basic Edition and
Standard Edition support.
HPC with Red Hat Enterprise Linux WS
Red Hat Enterprise Linux WS is usually the most cost effective Enterprise
Linux product for use in High Performance Computing (HPC) environments. In
these environments it is deployed in a headless workstation mode without a
monitor, keyboard or mouse. A few common HPCrelated
packages are
included in the Enterprise Linux family such as PVM and LAM.
Red Hat Desktop
Red Hat Desktop is the highvolume
desktop/client member of the Red Hat
Enterprise Linux family. It supports 32bit
Intel x86 and 64bit
Intel EM64T and
AMD64 systems with one CPU and up to 4 GB of main memory. It provides
the same software functionality as Red Hat Enterprise Linux WS but for
smaller systems and at a lower price point. Red Hat Desktop is provided in
multiunit
packages bundled with a Red Hat Network (RHN) Proxy or Satellite
Server. The RHN server is used to efficiently perform desktop management
functions such as the installation of updates and security patches.
