🌐 Cloud Computing Service Models: A Complete Guide by teShaHch
Cloud computing is the backbone of today’s digital transformation. From startups to global enterprises, everyone is leveraging the cloud. But the big question is – which service model should you choose?
At teShaHch, we simplify the different Cloud Service Models – SaaS, PaaS, IaaS, and the extended models.
1️⃣ IaaS (Infrastructure as a Service)
- What it offers: Servers, storage, networking, virtual machines.
- Who manages what: Provider → Infrastructure | User → OS, Apps, Security
- Examples: AWS EC2, Google Compute Engine
- Analogy: Renting an empty kitchen space and setting up everything yourself.
2️⃣ PaaS (Platform as a Service)
- What it offers: Infrastructure + Runtime environment + Development tools.
- Who manages what: Provider → Platform | User → Application
- Examples: Google App Engine, Heroku
- Analogy: A ready kitchen where you just cook.
3️⃣ SaaS (Software as a Service)
- What it offers: Fully functional ready-to-use software.
- Examples: Gmail, Zoom, Dropbox
- Analogy: Eating ready-made food at a restaurant – no cooking needed.
🔄 Extended Cloud Service Models
4️⃣ FaaS (Function as a Service) / Serverless
👉 Run code without managing servers.
- Examples: AWS Lambda, Google Cloud Functions
- Analogy: You ask a waiter for tea, and they serve it without you entering the kitchen.
5️⃣ CaaS (Container as a Service)
👉 Container deployment and orchestration (Docker, Kubernetes).
- Examples: Google Kubernetes Engine, Amazon ECS
- Analogy: Separate cooking stations in a kitchen for each chef.
6️⃣ DaaS (Desktop as a Service)
👉 Virtual desktops accessible from anywhere.
- Examples: Amazon WorkSpaces, Citrix
- Analogy: No matter where you sit in a restaurant, your table setup is the same.
7️⃣ DBaaS (Database as a Service)
👉 Fully managed databases with scaling, backups, and monitoring.
- Examples: Amazon RDS, MongoDB Atlas
- Analogy: Ingredients are always available in the restaurant store, you just use them for recipes.
8️⃣ BaaS (Backend as a Service)
👉 Ready backend for mobile & web apps (auth, notifications, DB).
- Examples: Firebase, AWS Amplify
- Analogy: All ingredients are pre-prepared – you only serve them on plates.
9️⃣ STaaS (Storage as a Service)
👉 On-demand cloud storage solutions.
- Examples: Google Drive, Amazon S3
- Analogy: A storage room in the restaurant where everything is organized and accessible.
