Study Notes

Traditional Computing Model

Infrastructure is typically viewed as physical hardware requiring substantial space, staff, security, planning, and capital expenditure.
Involves significant upfront investments and lengthy hardware procurement cycles.
Capacity provisioning relies on estimated theoretical maximum peaks, often leading to resource inefficiencies.
Risk of under-provisioning results in lack of capacity, while over-provisioning incurs costs for unused resources.
Setting up new infrastructure demands time and resources, including hardware purchase, installation, and management.

Cloud Computing Advantages

Transforms the perception of infrastructure from hardware to software.
Promotes flexibility and scalability in resource management, reducing dependency on physical assets.

Cloud Computing Models

Infrastructure as a Service (IaaS):
- Provides fundamental cloud IT building blocks like networking, computing, and storage.
- Offers high flexibility and control, closely resembling traditional IT resources.
Platform as a Service (PaaS):
- Minimizes the need to manage underlying infrastructure (hardware and OS).
- Allows greater focus on application deployment and management rather than infrastructure.
Software as a Service (SaaS):
- Delivers fully managed applications by service providers, requiring no maintenance effort from users.
- Example includes web-based email services, where users engage without needing to manage servers or software updates.
