3. WHAT IS IT INFRASTRUCTURE? “IT Infrastructure is the set of physical and virtual resources that supports the flow, storage and processing of data within an organization.” Components: Hardware Soft ware Networks Services

4. COMPONENTS OF IT INFRASTRUCTURE Hardware Servers: Computers that provide services or resources. Network Devices : Routers, Switches and access points that facilitate communication. Storage Devices: Hardware for storing data (e.g. hard drives, SSDs).

5. COMPONENTS OF IT INFRASTRUCTURE Software Operating Systems : Software that manages hardware and software resources (e.g., Windows, Linux). Applications: Programs that perform specific tasks (e.g., databases, email systems).

6. COMPONENTS OF IT INFRASTRUCTURE Networks Network Topologies: The arrangement of different elements (links, nodes, etc.) in a computer network. Protocols : Rules for communication between devices (e.g., TCP/IP).

7. COMPONENTS OF IT INFRASTRUCTURE Services Cloud Services : Online services that provide computing resources over the internet (e.g., AWS, Azure) . Managed Services : Outsourced services that handle IT operations (e.g., IT support).

8. BUILDING BLOCKS OF IT INFRASTRUCTURE Physical Infrastructure Data Centers: Facilities that house computing equipment and storage. Server Rooms: Dedicated spaces for servers within a data center. Cabling: The physical wiring that connects different hardware components .

9. BUILDING BLOCKS OF IT INFRASTRUCTURE Logical Infrastructure Virtualization: Technology that creates virtual versions of physical hardware. Software-Defined Networking: Network management and configuration done through software rather than hardware. .

10. BUILDING BLOCKS OF IT INFRASTRUCTURE Operational Infrastructure Monitoring Tools : Software that tracks the performance and health of IT systems. Backup Systems : Methods and tools to protect IT systems from threats. Security Measures : Techniques and Tools to protect IT systems from threats .

11. KEY DESIGN PRINCIPLES FOR IT INFRASTRUCTURE 1. Scalability : The ability of the infrastructure to grow and handle increased demand. Example : Adding more servers to handle higher traffic.

12. KEY DESIGN PRINCIPLES FOR IT INFRASTRUCTURE 2 . Reliability : Ensuring the infrastructure consistently performs well and remains available. Example : Redundant systems to prevent downtime.

13. KEY DESIGN PRINCIPLES FOR IT INFRASTRUCTURE 3 . Performance : The efficiency and speed at which the infrastructure operates. Example : Optimizing network bandwidth and processing power.

14. KEY DESIGN PRINCIPLES FOR IT INFRASTRUCTURE 4 . Security: Protecting data and resources from unauthorized access and attacks. Example : Implementing firewalls and encryption.

15. IT INFRASTRUCTURE ARCHITECTURE FRAMEWORK 1. Architectural Models Traditional Model: On-premises systems and hardware. Modern Model: Cloud-based services and virtualized resources.

16. IT INFRASTRUCTURE ARCHITECTURE FRAMEWORK 2 . Design Layers Physical Layer: The hardware components and physical connections. Logical Layer : The abstract layer managing virtual resources. Application Layer: The software and services used by end-users.

17. IT INFRASTRUCTURE ARCHITECTURE FRAMEWORK 2. Best Practices Modular Design: Building systems in a way that allows easy upgrades and scaling. Standardization: Using common standards and practices for compatibility and efficiency. Documentation : Keeping detailed records of the infrastructure design and configuration.

18. CONCLUSION Key Takeaways Understanding the fundamental components and principles of IT infrastructure goals. Next Steps: Exploring specific components and design considerations.

19. Q&A Questions or Discussion Points?

20. ASSIGNMENT Choose one design principle of IT Infrastructure from the lecture and write a short paragraph explaining its importance in IT Infrastructure. Include an example of how this principle might be applied in a practical scenario.
