I. Introduction to Cloud Computing
Cloud computing is a revolutionary model for delivering IT services over the internet. It provides OnDemand access to a shared pool of configurable computing resources, including networks, servers, storage, applications, and services.
Key Characteristics:
1. OnDemand self-service
2. Broad network access
3. Resource pooling
4. Rapid elasticity
5. Measured service
II. Types of Cloud Computing
1. Public Cloud
Owned and operated by third-party cloud service providers
Resources are shared among multiple organizations
Examples: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform
Advantages:
Cost-effective
Highly scalable
No maintenance responsibilities
Disadvantages:
Less control over infrastructure
Potential security concerns
2. Private Cloud
Dedicated to a single organization
Can be managed internally or by a third party
Located on-premises or offsite
Advantages:
Greater control and customization
Enhanced security and privacy
Disadvantages:
Higher costs
Limited scalability
3. Hybrid Cloud
Combination of public and private clouds
Allows data and applications to move between private and public clouds
Advantages:
Flexibility and scalability
Costeffectiveness
Improved security options
Disadvantages:
Complexity in management
Potential integration challenges
4. Community Cloud
Shared by several organizations with common concerns (e.g., security, compliance)
III. Cloud Service Models
1. Infrastructure as a Service (IaaS)
Provides virtualized computing resources over the internet
领英推荐
Examples: AWS EC2, Google Compute Engine
2. Platform as a Service (PaaS)
Offers a platform for developers to build, run, and manage applications
Examples: Heroku, Google App Engine
3. Software as a Service (SaaS)
Delivers software applications over the internet
Examples: Salesforce, Google Workspace
