Cloud Computing Models

• Five Basic Application Components:

  • Network: LAN cards/cables
  • Storage: SSD / HDD
  • Computing: CPU / RAM
  • OS: Windows / Linux
  • Application

• Categorized based on the components provided:

  • IaaS
  • Infrastructure as a Service: Only infrastructure is provided.
  • Includes Network + Storage + Computing; users install the OS and applications themselves.
  • Similar to renting a virtual computer.
  • Example: AWS EC2
  • PaaS
  • Platform as a Service: Provides all components except for application code.
  • Offers infrastructure, servers, and other necessary components for application development, allowing users to simply upload and run their code.
  • Example: Firebase, Supabase
  • SaaS
  • Software as a Service: Includes infrastructure, OS, and necessary software.
  • Provides the service itself, allowing users to access and use it without additional setup.
  • Examples: Gmail, Slack, Dropbox, etc.

Cloud Computing Deployment Models

• Public (Cloud) Model

  • All application-related activities are executed within the cloud.
  • Low resource costs.
  • High scalability.

• Private Model

  • Offers the highest level of customization.
  • Expensive initial resource costs.
  • High maintenance resource costs.
  • Enhanced security.

• Hybrid Model

  • A mix of private and public models.
  • Often used during the transition from private to public.
  • Commonly used as a backup for private models.
