1) What are the Cloud Computing Services?
2) Define IaaS, PaaS, SaaS, and give example for each?
3) If a developer want to focus purely on application what cloud service model should he choose?
4) If a company needs email for 500 employees what service model should it choose?
5) Difference between IaaS and PaaS?
1.Cloud computing services are on-demand delivery of IT resources over the internet, primarily categorized into three core service models: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service).
2.IaaS (Infrastructure as a Service): Provides virtualized computing resources (servers, storage, networking) over the internet. Example: Amazon EC2, Microsoft Azure VMs.
PaaS (Platform as a Service), because it abstracts away infrastructure management (OS, servers, databases, runtime), letting the developer focus exclusively on writing and deploying code.
SaaS (Software as a Service), because complete, ready-to-use email solutions (like Microsoft 365 or Google Workspace) require no custom application development or infrastructure setup.
3.PaaS (Platform as a Service), because it abstracts away infrastructure management (OS, servers, databases, runtime), letting the developer focus exclusively on writing and deploying code.
4.SaaS (Software as a Service), because complete, ready-to-use email solutions (like Microsoft 365 or Google Workspace) require no custom application development or infrastructure setup
5. IAAS(Infrastructure as a service) provides raw, virtualized computing resources such as virtual servers, storage, and networking, leaving the user responsible for managing the operating system, middleware, runtime environments, and applications. In contrast, PaaS (Platform as a Service) provides a pre-configured platform that includes the operating system, runtime, and development tools, allowing developers to focus solely on writing and deploying application code while the cloud vendor manages and maintains the underlying infrastructure.
