There is although a strong difference between mainframe and x86 servers when you look at PEOPLE.<br />
You have tons of vSphere/RHEL/Debian/Window<wbr />s operators and admins available...and most of the time, you can't get out of them because there is always some support needs on those OS...

hi all<br />
<br />
i never had experience on mainframe architecture, but I do know about regular enterprise tier architecture.<br />
now, I would like to get more info and understand about mainframe a little more.<br />
can anymore get me some straight explanations on differences on both??<br />
<br />
thanks a lot

mainframe vs tiered architecture

A mainframe operating system is networking software infrastructure that allows a mainframe computer to run programs, connect linked machines, and process complex numerical and data-driven tasks. Modern mainframe design is generally defined by redundant internal engineering, extensive input-output facilities, strict backward compatibility with older software, high hardware and computational utilization rates and high stability and reliability. Well-known operating systems include IBM z/OS, z/VM, zTPF, z/VSE, OS/390, and their predecessors, along with MCP for Unisys ClearPath, and NonStop OS/Guardian on HP/Tandem, and questions regarding the IBM midrange operating system called IBM i, OS/400, and i5/OS.

Mainframe OS

An application server is a software framework that provides both facilities to create applications and a server environment to run them. Most application server frameworks contain a comprehensive service layer model, acting as a set of components accessible to the software developer through an API defined by the platform itself. For Web applications, these components are usually performed in the same running environment as their web server(s), and their main job is to support the construction of dynamic pages. However, many application servers target much more than just Web page generation: they implement services like clustering, fail-over, and load-balancing.

Application Servers

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
