A customer uses an ATM, which presents a user- friendly interface for various functions: Withdrawal, query account balance, deposit, transfer, or cash advance from a credit card account. 2. Elsewhere in the same private network, a bank employee in a branch office performs operations such as consulting, fund applications, and money ordering. 3. At the bank’s central office, business analysts tune transactions for improved performance. Other staff use specialized online systems for office automation to perform customer relationship management, budget planning, and stock control. 4. All requests directed to the mainframe computer for processing. 5. Programs running on the mainframe computer perform updates and inquires to the database management system (for example, DB2). -

Mainframe Hardware Course: Mainframe’S Processors
Mainframe hardware course: Mainframe’s processors z/OS Basic Skills: The mainframe’s processors Mainframe’s processors This hardware course introduces you to one model of IBM® mainframe computer, the IBM System z9™, to help you learn about the hardware parts that constitute the mainframe’s processor by comparing processing parts and functions to personal computers or notebooks. Time to complete: 10 - 15 minutes ¾The central processor complex ¾The multichip module ¾Memory cards ¾Input/output connections ¾The mainframe’s processing capacity © Copyright IBM Corp. 2006. All rights reserved. The central processor complex z/OS Basic Skills: The mainframe’s processors Mainframe’s processors > The central processor complex Mainframes have one or two metal frames that contain specialized cages, as well as other physical elements. This diagram shows the interior front view of an IBM System z9 Enterprise Class (z9 EC) model that has two frames. The z9 EC is slightly larger than a household refrigerator. The central processor complex, or CPC, resides in its own cage inside the mainframe, and consists of one to four book packages. Just like its personal-computer counterpart, the motherboard or system board, each book package consists of processors, memory, timers, and I/O connections. These collections of hardware parts are called “book packages” because you can slide them in or out of the CPC cage almost as easily as you can slide a book on or off a bookshelf. © Copyright IBM Corp. 2006. All rights reserved. z/OS Basic Skills: The mainframe’s processors Mainframe’s processors > The book package In the System z9, as well as earlier IBM mainframe models, the book package consists of three distinct areas, one each for: • The z9 EC's processors, which are inside one multichip module • Memory cards • Connections to input/output devices All of the book packages plug into a backplane in the z9 EC's frame. -

The Business Value of Legacy Modernization
The Business Value of Legacy Modernization Custom Research Note Published: July 2007 For the latest information, please see www.microsoft.com/mainframe Executive Summary This paper outlines the reasons and provides guidance for developing a legacy modernization strategy. We will discuss the choices to be made and outline the key steps involved in creating this strategy. Along the way, we examine real-life modernization stories. Because we focus on the impact of legacy modernization on business rather than on the technical implementation, no detailed technical knowledge is required. Perhaps the single most important fact to note is that most organizations with mainframe-based systems are spending about 75 percent of their development resources simply to maintain existing applications, which leaves only 25 percent of their development resources for innovation. Effecting a 25-percent reduction in maintenance costs means that investment in innovation can be almost doubled. The key choices in legacy modernization are application extension, migration, redevelopment, and replacement. These choices can be used individually or in combination. We offer a simple legacy modernization strategy framework to help you find an appropriate solution for your organization. Finally, the legacy modernization ecosystem is growing. Many hardware, software, and service providers see an opportunity to provide value in this market. Microsoft recognizes the complexity of legacy modernization and that selecting the right technology platform and solution partner are
