The IT Infrastructure Ecosystem Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS The IT Infrastructure Ecosystem

Computer Hardware Platforms Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Computer Hardware Platforms $110 billion annually spent in the United States Dominance of Intel, AMD, and IBM 32-bit processor chips at the client level Server market increasingly dominated by inexpensive generic processors from the same manufacturers

Computer Hardware Platforms (Continued) Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Computer Hardware Platforms (Continued) Strong server market growth for 64 bit generic processors from AMD, Intel and IBM Blade servers replace box servers Mainframes continue as a presence working as very large servers

Operating System Platforms Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Operating System Platforms $100 billion annually spent in the United States Continued dominance of Microsoft OS in the client (95%) and handheld market (45%) Growing dominance of Linux (UNIX) in the corporate server market (85%) Windows 2002 and 2003 Server remains strong in smaller enterprises and workgroup networks

Enterprise Software Applications Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Enterprise Software Applications $165 billion annually spent in the United States for basic enterprise software infrastructure SAP, Oracle, PeopleSoft (now Oracle), and Siebel dominate this market. Middleware firms like BEA and JD Edwards serve smaller firms, and work also in the Web services space.

Enterprise Software Applications (Continued) Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Enterprise Software Applications (Continued) The enterprise market is consolidating around a few huge firms that have gained significant market share such as SAP and Oracle. Microsoft is expanding into smaller firm enterprise systems where it can build on its Windows server-installed base.

Data Management and Storage Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Data Management and Storage $70 billion annually spent in the United States. Oracle and IBM continue to dominate the database software market. Microsoft (SQL Server) and Sybase tend to serve smaller firms. Open source Linux MySQL now supported by HP and most consulting firms as an inexpensive, powerful database used mostly in small to mid-size firms.

Data Management and Storage (Continued) Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Data Management and Storage (Continued) $35 billion annually spent in the United States for physical hard disk storage The hard disk market is consolidating around a few huge firms like EMC and smaller PC hard disk firms like Seagate, Maxtor, and Western Digital

Networking/Telecommunications Platforms Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Networking/Telecommunications Platforms $150 billion annually spent on networking and telecommunications hardware $700 billion annually spent on telecommunications services, e.g. phone and Internet connectivity Local area networking still dominated by Microsoft Server (about 75%) but strong growth of Linux challenges this dominance

Internet hardware server market concentrated in Dell, HP, and IBM Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Internet Platforms $32 billion annually spent on Internet infrastructure in the United States Internet hardware server market concentrated in Dell, HP, and IBM Prices falling rapidly by up to 50% in a single year for low-power servers

Internet Platforms (Continued) Management Information Systems Chapter 6 IT Infrastructure and Platforms     INFRASTRUCTURE COMPONENTS Internet Platforms (Continued) Open-source Apache remains the dominant Web server software, followed by Microsoft’s IIS server. Sun’s Java grows as the most widely used tool for interactive Web applications. Microsoft and Sun settle a long-standing law suit and agree to support a common Java.

The Rise of Linux and Open-Source Software Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS The Rise of Linux and Open-Source Software Open-source software is free and can be modified by users. Developed and maintained by a worldwide network of programmers and designers under the management of user communities

Java is embedded in PDAs, cell phones, and browsers. Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS Java Is Everywhere Java: An operating system—Independent, processor-independent, object-oriented programming language Applications written in Java can run on any hardware for which a Java virtual machine has been defined. Java is embedded in PDAs, cell phones, and browsers. Java is a leading interactive programming environment for the Web.

Software for Enterprise Integration: Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS Software for Enterprise Integration: One of the most important software trends of the last decade is the growth of “enterprise in a box” or the purchase of enterprise-wide software systems by firms. Rather than build all their own software on a custom basis, large firms increasingly purchase enterprise applications prewritten by specialized software firms like SAP, Oracle, PeopleSoft, and others.

Software for Enterprise Integration: (Continued) Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS Software for Enterprise Integration: (Continued) The goal is to achieve an integrated firm-wide information environment, reduce cost, increase reliability, and to adopt business best practices which are captured by the software. Enterprise software firms achieve economies of scale by selling the same software to hundreds of firms. Today's enterprise systems are capable of integrating older legacy applications with newer Web-based applications.

Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS Enterprise Application Integration (EAI) Software Versus Traditional Integration EAI software (a) creates a common platform through which all applications can freely communicate with each other. EAI requires much less programming than traditional point-to-point integration (b).

Web Services and Service-Oriented Architecture Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS Web Services and Service-Oriented Architecture Web Services: An alternative to enterprise systems is to use new Web-based standards to create a communication platform allowing older applications to communicate with newer applications. Web services refers to a set of loosely coupled software components that exchange information with each other using Web communication standards and languages.

Web Services and Service-Oriented Architecture (Continued) Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS Web Services and Service-Oriented Architecture (Continued) Web services permit computer programs to communicate with one another and share information without rewriting applications, or disturbing older legacy systems.

Purchase of Software Packages and Enterprise Software (Continued) Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS Purchase of Software Packages and Enterprise Software (Continued) Application Service Providers: Rather than purchase hardware and software, firms can go onto the Internet and find providers who offer the same functionality over the entertainment, and charge on a per-user or license basis. Example: Salesforce.com provides customer relationship management and sales force management services to firms

Software Outsourcing of Custom Applications Management Information Systems Chapter 6 IT Infrastructure and Platforms CONTEMPORARY SOFTWARE PLATFORM TRENDS Software Outsourcing of Custom Applications A firm contracts custom software development or maintenance of existing legacy programs to outside firms, often in low-wage countries. Example: Dow Chemical hired IBM for $1.1 billion to create an integrated communication system for 50,000 Dow employees in 63 countries. Why would Dow not build this system itself?
