Study Notes
Cloud Computing Layered Architecture
- Cloud computing is a business model, not a technology.
-
Infrastructure as a Service (IaaS): The foundational layer, comprising hardware and networks. It emphasizes scalability and virtualisation.
- Scalability: IaaS vendors provide massive infrastructure, rendering the cost of adding resources almost negligible.
- Virtualisation: Software virtualizes hardware, allowing for efficient resource utilisation (around 90%) compared to traditional hosting.
-
Platform as a Service (PaaS): This layer provides resources for app development, testing, running, and hosting, complementing IaaS.
- Third Party Integrations: Allows developers to integrate third-party software into cloud services.
- Example: Microsoft Azure offers a comprehensive development and deployment environment for building and hosting applications.
-
Software as a Service (SaaS): This layer represents the user's direct interaction with the cloud service provider's offering.
- Web-Based and Device-Independent: SaaS is accessible from anywhere and on any device, leveraging the power of the web.
- Clarification: Cloud and SaaS are not mutually exclusive; SaaS is a layer within the cloud framework.
-
Business Process Outsourcing (BPO): The top layer of the cloud, representing outsourcing services to a vendor.
- Business Model Focus: While not inherently technological, BPO is considered a cloud layer due to its focus on business models, mirroring the other layers.
- Importance of Model: Understanding the layered architecture is crucial to comprehending the core principles of cloud computing.
Application Layer
- This layer is responsible for user interaction and application logic.
- It includes user interface elements, business logic, and data access mechanisms.
- Example: In an e-commerce website, the application layer manages the display of products, shopping carts, and payment processing.
Other Information
