Unit 1.1: Technology Infrastructure

Technology infrastructure

Foundational systems that support computing and connectivity, including hardware, software, networks, databases, cloud, people, and processes.

On-Premises Infrastructure

Physical hardware located within the organization, such as PCs, servers, and data centers.

Pros of On-Premises Infrastructure

Full control over systems and security; internal data management.

Cons of On-Premises Infrastructure

High upfront cost; requires maintenance and IT staff.

Cloud Infrastructure

Remote computing resources accessed via the internet like AWS, Microsoft Azure, and Google Cloud.

Pros of Cloud Infrastructure

Easy scalability, lower upfront cost, accessible from anywhere.

Cons of Cloud Infrastructure

Requires internet connection; shared security responsibility.

Key Difference between Traditional and Cloud

Traditional (On-Prem) = control + responsibility; Cloud = flexibility + scalability.

Components of Technology Infrastructure

Include people, processes, hardware, software, networks, databases, and cloud.

People in Technology Infrastructure

IT professionals and users who manage and operate systems.

Processes in Technology Infrastructure

Procedures and rules that ensure efficiency and security.

Hardware in Technology Infrastructure

Physical devices such as computers, servers, and routers.

Software in Technology Infrastructure

Programs and applications that instruct hardware on what to do.

Networks in Technology Infrastructure

Connect devices and systems to enable communication and data sharing.

Databases in Technology Infrastructure

Store and organize data for fast retrieval and management.

Cloud in Technology Infrastructure

Remote systems that provide storage and computing, offering flexibility and scalability.

Traditional Infrastructure vs Cloud Infrastructure

Traditional uses on-site servers and requires physical hardware, while cloud is hosted remotely and utilizes virtualized resources.

Key Concepts of Technology Infrastructure

Infrastructure is the foundation of IT systems, with all components working together to move and manage data.

Common Test Point about Cloud

Cloud advantage includes scalability and reduces the need for physical hardware.
