Study Notes

Traditional IT Process

Sequential phases: Decision to Go Ahead → PO Issued → HW Implementation → SW Implementation
Key steps in hardware implementation include selecting vendors, shipment, and preparing data centers.
Software implementation involves licensing, cabling, installation, testing, and user acceptance testing (UAT).
Timelines: 1-2 months for decision and purchase order, 2-3 months for hardware, 1-2 months for software, culminating in a total deployment period of 6-12 months.

Inefficiencies in Traditional IT

Common issues include "under-supply" of IT capacities leading to missed opportunities.
"Waste" of IT resources occurs due to fixed costs associated with maintaining excess capacities.
Traditional practices create barriers to innovation due to inflexibility and inefficiency.

Cloud: A Better Alternative

Cloud provision allows for rapid environment setup (servers, networks, apps) within minutes.
Pay As You Go (PAYG) pricing model enables customers to pay only for the resources they consume.
Capacity can be adjusted dynamically, allowing for addition or removal based on real-time needs.
Clients can terminate services without further payment, providing a flexible cost structure.

Cloud Computing in the IT Industry

Cloud computing likened to electricity, removing the need for companies to maintain their own data centers.
Businesses can focus on core activities without the overhead of data center management and staffing.
Transition to cloud frees up resources and reduces operational costs significantly.

The Cloud Way

Improved IT capacity management with no under-supply issues, alleviating over-supply risks.
Cloud solutions simplify IT investments by allowing for adjustments in resource allocation based on actual load.
Reduction of initial capital investment is a significant advantage with cloud solutions.

Introduction to Cloud Computing

Lecture outline includes: Evolution of IT infrastructure, cloud characteristics, service and deployment models, service providers, and benefits of cloud computing.

Evolution of IT Infrastructure

Historical progression includes: Mainframe/Mini Computers → Personal Computers → Client/Server → Web-Based Applications → Cloud/Mobile Computing.

History of Electricity as an Analogy

In the mid-1800s, businesses generated their own electricity, leading to high costs and operational challenges.
Emergence of electricity providers in the late 1800s simplified access to power, replacing self-generation.
Businesses benefited from reduced costs, no maintenance of complex machinery, and flexible pricing based on consumption.
