Cloud Computing
Categories Of Cloud Computing
- Platform As A Service (PAAS)
- Software As A Service (SAAS)
- Infrastructure As A Service (IAAS)
- Mobile backend as a service (MBaaS)
- Serverless computing
- Function as a service (FaaS)
Real-World Analogy Of Cloud Computing Categories
| Option | Analogous to |
|---|
| Drive your own car - You have the flexibility of taking the route you want.You have to take care of the right route and the traffic signals | IAAS. Because you are required to manage the infrastructure.Example - Virtual Machine |
| Book a cab - You don’t have to worry about the routes and traffic signals.You have the flexibility to ask the cab driver to move the cab beyond your destination. | PAAS. Because you aren't required to manage the infrastructure. You can build and deploy your application.Example - App service. |
| Use public transport like bus. The public transport has a fixed path and you don’t have any option for any route change. | SAAS. Because you can use the application created by the vendor. You don’t have the option for any customization. Example - Gmail, Dropbox etc. |
Types Of Cloud Network
| Cloud Network Type | Description |
|---|
| Private cloud | A private cloud is a cloud computing environment dedicated to a specific organization, typically hosted on-premises, offering greater control and security than public or hybrid clouds, with the organization’s IT department responsible for managing its infrastructure and associated costs. |
| Public cloud | A public cloud provides computing services offered by third-party providers over the internet and can typically be deployed faster than a private cloud. |
| Hybrid cloud | A hybrid cloud combines public and private cloud environments, allowing applications and data to be shared between them, with non-sensitive data typically handled by the public cloud and sensitive data managed through a private, often on-premises, cloud. |
| Community model | A community cloud model is like a private cloud, but the infrastructure and resources are shared by multiple organizations that have common goals, requirements, or interests. |
