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.
