Study Notes

Cloud Computing Basics

Increasing demand for compute, storage, and networking resources in the fast-growing ICT industry.
Cloud computing emerged to provide on-demand resources and promote business innovation.

Background of Cloud Computing

The mobile Internet and connected devices lead to unprecedented data growth and challenges for traditional ICT.
Transition from the PC era (networked computers) to the mobile era (applications on mobile devices) and now to the Internet of Everything (IoE).
IoE encourages competition for ecosystem dominance among enterprises.
Each era features dominant platforms:
- PC era: Windows, Intel, x86 architecture.
- Mobile era: iOS, Android, ARM architecture.
Future industries will be led by companies mastering core chips and operating systems.

Challenges of Conventional IT Architecture

Increased user traffic and data require continuous investment in traditional IT infrastructure.
Drawbacks of traditional IT include:
- Long procurement processes hindering responsive business systems.
- Centralized architecture with poor scalability.
- Independent reliability of devices reliant on software.
- Heterogeneous devices causing management difficulties.
- Limited performance per device with low utilization yet high costs.

Migration to Cloud Architecture

Traditional IT architecture requires extensive physical resources and capital, typically installed locally.
Virtualization technology allows computer components to run in virtual environments, maximizing physical hardware utilization.
Cloud transformation involves transitioning from:
- Resource silos to resource pooling.
- Centralized to distributed architecture.
- Dedicated hardware to software-defined storage (SDS).
- Manual processes to self-service and automation.
- Distributed statistics to unified metering.

Definition of Cloud Computing

A model for ubiquitous, on-demand network access to configurable computing resources, requiring minimal management.
Cloud metaphorically represents networks and the underlying Internet infrastructure.
Offers on-demand IT services analogous to utility services like water and electricity.

Hybrid Cloud

Combines public cloud and private cloud resources, remaining distinct while integrated.
Enables the migration of workloads across cloud environments as required.

Service Models for Cloud Computing

Infrastructure as a Service (IaaS): Provides infrastructure (servers, storage, networks) while users focus on system and application layers.
Platform as a Service (PaaS): Offers infrastructure and application deployment environments, allowing users to concentrate on applications and data.
Software as a Service (SaaS): Delivers all necessary resources and applications, focusing user attention solely on using applications.
Cloud services offer flexibility and lower costs compared to traditional procurement of IT resources.

Benefits of Cloud Computing

Integrates hardware resources in software, dynamically allocating resources to applications.
Supports auto-scaling and optimizes work efficiency.
Centralizes data storage, enhancing asset utilization while achieving energy savings and easier maintenance.
Results in lower costs and higher efficiency across various dimensions.
