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.
