1 C5- IT Infrastructure and Emerging Technologies
Let us buy some Blade Servers!

2 reduce wasted computer resources not used for processing, use existing resources more efficiently, and cut costs and power consumption. Invest on hardware and software technologies that are cost-effective, efficient, and energy-saving.

3 Computers 3 A computer Takes data as input Processes it Outputs information CPU  Central Processing Unit Primary Storage RAM  Random Access Memory ROM  Read Only Memory Secondary Storage, Input/Output Devices, Communications Devices Input – Process - Output 3

4 Evolution of IT Infrastructure
General-purpose mainframe and minicomputer era (1959 – present) Personal computer era (1981 to present) Client/server era (1983 to present) Enterprise computing era (1992 to present) Cloud and mobile computing era (2000 to Present)


6 IT Infrastructure Fit 1. Technological 2. Service
6 1. Technological hardware/software needed to operate Capacity, speed 2. Service Services provided by the IT infrastructure Computing platforms, telecommunications, data management, etc. 6

9 The future! Technology Drivers
9 Moore’s Law The power of microprocessors doubles every 18 months Computing power doubles every 18 months The price of computing falls by half every 18 months Law of Mass Digital Storage The amount of digital information is roughly doubling every year The cost of storage is falling at an exponential rate of 100 percent per year Metcalf’s Law The value of a network grows exponentially as a function of the number of network members Metcalfe’s Law and Network economics: If you build a network for ten users, you‘ll spend the necessary money for the basic equipment. If you already have the equipment in place, you can add one more user at nominal costs. However, the additional user will bring value to the network far beyond what it costs to add him/her 9

10 Technology Drivers … Declining Communications Costs and the Internet
10 Declining Communications Costs and the Internet Rapid decline in costs of communication and the exponential growth in the size of the Internet Standards and network effects ASCII (1958) COBOL (1959) Unix (1969–1975) TCP/IP (1974) Ethernet (1973) IBM/Microsoft/Intel Personal Computer (1981) World Wide Web (1989–1993) Network Effects 10

11 7 Components of an IT infrastructure

12 IT infrastructure Components …
Computer Hardware Platforms Blade servers Operating System Platforms Unix and Linux Enterprise Software Applications SAP, Oracle Data Management and Storage Storage Area Networks (SANs)

13 IT infrastructure Components …
Networking/Telecommunications Platforms Combination of telephone services, cell phone connectivity, computers and peripheral devices, handheld PDAs, and wireless services Internet Platforms Intranets/extranets using internet platform Consulting and System Integration Services Legacy Systems Consulting and System Integration Most firms today, even large firms, cannot develop their systems without significant outside help Must ensure new systems integrate with legacy systems Consulting and systems integration is a lucrative market Companies choose not to totally replace legacy systems because it‘s too expensive, involves too much training, and carries too much organizational change.

14 Hardware Platform Trends
and Emerging Technologies Integration of Computing & Telecommunications Increasingly, computing takes place over the network Client level: The integration of cell phones and PDAs Server level: The integration of voice telephone and the Internet bring together two historically separate and distinct global networks The network in many respects is the source of computing power

15 Hardware Platform The Emerging Mobile Digital Platform Grid Computing
17 The Emerging Mobile Digital Platform Netbooks, Smart Phones Grid Computing connecting geographically remote computers short-term access to large computational capacity compare with mainframes/super computers Virtualization multiple operating systems and application programs on one server overall utilization rates, maintenance, upgrades … TCO Here‘s a list of the benefits businesses enjoy from using virtualization:  Increase equipment utilization rates  Conserve data center space and energy usage  Require fewer computers and servers  Combine legacy applications with newer applications  Facilitate centralization and consolidation of hardware administration 15

16 Hardware Platform … Cloud computing Cloud services Green Computing
On-Demand computing (Utility Computing) off-load to a remote and large-scale data processing center. Cloud services Cloud infrastructure as a service Cloud platform as a service Cloud software as a service Green Computing CIBC out sources to HP 28,000 ; 41,000 desktops PCs, 4,500 ATMs, and 10,000 POS terminals. 16

17 Hardware Platform … Autonomic Computing
Cost of managing them has risen 30%-50% to prevent crashing! Features: Configure themselves Optimize and tune themselves Heal themselves when broken Protect themselves from intruders and self-destruction Autonomic computing is an industry-wide effort High-Performance and Power-Saving Processors 17

18 Hardware Platform … Edge Computing
20 Edge Computing A multi-tier, load-balancing scheme for Web-based applications Processing load is distributed closer to the user and handled by smaller, lower-cost servers 18

19 Software Platform Evolution
Five themes Linux and open-source software OpenOffice Software for the Web: Java and Ajax Web Services and Service-Oriented Architecture XML/SOAP for data transfer Software Outsourcing and Cloud Services Software Packages and Enterprise Software Software as a service (SaaS) 5-48

20 Software Platform Evolution …
Linux and Open Source free and can be modified by users Developed and maintained by a worldwide network of programmers and designers under the management of user communities Software Platform Evolution 20

21 Software Platform Evolution …
Java is an operating system-independent, processor-independent, object-oriented programming language The leading interactive programming environment for the Web Enterprise Integration Priority of integrating legacy systems with newer Web-based applications Growth of enterprise-wide applications Use of middleware to create an interface or bridge Enterprise Application Integration (EAI) software packages connect disparate applications 21

22 Management Issues Dealing with Platform and Infrastructure Change
Management and Governance Making Wise Infrastructure Investments Consider TCO

23 Software Platform Trends and Emerging Technologies

24 Software Platform Evolution
Web Services a set of loosely coupled software components that exchange information with each other using Web communication standards and languages Foundation technology is XML Service-oriented architecture Major vendors provide tools for building software using Web services 24

25 Software Outsourcing 28 Today large and small firms purchase most of their software from outside vendors. Three kinds of outsourcing: Purchase of software packages Using application service providers (may rent)‏ Custom outsourcing 25

26 Sources of Software Software package
29 Software package Prewritten off-the-shelf software Application Service Providers (ASP): A business that delivers and manages applications and computer services from remote computer centers to multiple users using the Internet or a private network Software outsourcing Contract the development of custom software 26

27 Management Challenges
27 Making wise infrastructure investments Choosing and coordinating infrastructure components Dealing with infrastructure change scalability Management and governance Model total cost of ownership (TCO)‏ 27
