Cloud Service Models: IaaS, PaaS, Serverless, and SaaS

Dive deeper into the three primary cloud service models: • Infrastructure as a Service (IaaS): Virtualized data centers (e.g., Google Compute Engine). • Platform as a Service (PaaS): Developer-friendly environments (e.g., Google App Engine). • Serverless Computing: Code-only focus (e.g., Cloud Run, Cloud Functions). We’ll compare their trade-offs (control vs. simplicity), pricing models, and use cases, plus touch on SaaS(e.g., Gmail) and how it fits into the cloud ecosystem. Key Takeaways: ✔️ When to use IaaS, PaaS, or serverless. ✔️ How managed services accelerate innovation. ✔️ Real-world examples from Google Cloud.
