Study Notes
Cloud Service Models
- Cloud services provide a range of benefits, including someone else taking care of tasks that we don't want to or can't do ourselves, such as hosting software applications.
- In an on-prem setup, we would need to manage physical servers, networking, storage, virtualization, operating systems, and applications ourselves.
Infrastructure-as-a-Service (IaaS)
- Provides virtual machines (VMs) that customers can configure and manage as needed
- Customers are responsible for the operating system, supporting software, data, and applications running on the VMs
- Service provider is responsible for the physical servers, storage, and virtualization
- Example: A software development company rents VMs and configures them to create a development environment
Platform-as-a-Service (PaaS)
- Provides a platform for developers to create code without worrying about individual VMs or infrastructure
- Customers are responsible for the applications and data, but not the operating systems or servers
- Service provider is responsible for the platform, operating systems, and infrastructure
- Example: AWS Elastic Beanstalk, which supports various development environments and languages
Software-as-a-Service (SaaS)
- Provides software applications over the internet, eliminating the need for customers to host or manage them
- Service provider is responsible for the entire application, including maintenance, updates, and security
- Customers simply log in and use the application
- Examples: Salesforce, Slack, Google Docs, and Gmail
Other Service Types
- Function-as-a-Service (FaaS): customers submit code to be executed, and the service provider runs it in the background
- Desktop-as-a-Service (DaaS): virtual machines are provided as desktops, which can be spun up and down as needed
- XaaS (Anything-as-a-Service): any service that can be delivered and consumed by a customer, such as Networking-as-a-Service or Storage-as-a-Service
