Study Notes
Cloud Computing Models
- Cloud computing encompasses more than just offsite computing devices. It offers various capabilities, including the easy deployment of new applications.
- Applications consist of multiple interconnected components (e.g., web servers, database servers, application servers). Cloud platforms enable deployment of all these components with a single action.
- Global accessibility and scalability are key benefits. Applications can be deployed across multiple data centers worldwide, allowing users to access them from the nearest location. Resources and application instances can be adjusted based on demand (scaling up or down). This dynamic resizing saves costs by only paying for used resources.
- Cloud deployments can be private, public, or hybrid.
- Private clouds are solely accessible to one organization, hosted within their own data center.
- Public clouds (like those from Amazon, Microsoft, and Rackspace) are shared resources accessible to multiple organizations.
- Hybrid clouds combine private and public cloud deployments, leveraging both models.
- Community clouds are shared among several organizations with a similar goal, sharing costs for private cloud infrastructure.
Cloud Deployment Models (IaaS, PaaS, SaaS)
-
Infrastructure as a Service (IaaS): Provides the raw computing infrastructure (servers, storage, networking). The user is responsible for the operating system, application, data, and other software.
- Example: A company needing servers for a website, but handling website design and content themselves.
-
Platform as a Service (PaaS): Offers a platform for development and deployment of applications, providing building blocks (modules) instead of raw infrastructure.
- Example: Salesforce.com, providing modules for building custom applications.
-
Software as a Service (SaaS): The cloud provider manages the entire application and data storage, making applications accessible via a web browser. Users don't need to install or manage the application.
- Example: Google Mail and Microsoft 365.
Management Responsibilities
- IaaS: End-users manage application, operating systems, data, and security. Providers handle hardware.
- PaaS: End-users manage applications and data, providers offer the platform and handle security.
- SaaS: Cloud provider manages all aspects of the application, storage, and application updates. End users only use it.
