Cloud Service Models

Hook

Renting infrastructure, a managed platform and finished software shifts different operational duties.

Watch

Choose AWS or GCP mapping, change one validated model parameter and load the trace. Provider labels identify concepts; the model never provisions resources or calls a provider account.

How it works

Compare IaaS, PaaS and SaaS against explicit task ownership. IaaS exposes guest OS/runtime/app maintenance, PaaS manages the runtime, and SaaS manages application source. Customer tenant-data policy and account credentials remain customer choices.

AWS and GCP comparison

AWS: EC2 IaaS / managed platform / SaaS concepts. GCP: Compute Engine IaaS / App Engine / Google SaaS concepts. This is a declared baseline, not every provider product contract. Google Workspace is a Google SaaS example, not a resource inside a GCP project. Actual contract, configuration and business requirements define each responsibility.

Try it

Change the service boundary and inspect which incomplete patch flags remain customer gaps. Then make a tenant data-access decision unsafe and explain why SaaS does not fix it. Predict the next modeled decision before advancing.

Complexity

Use the displayed measured operation and explicit bounds. Simulator operations, service quotas, network latency and cloud billing are different measurements. Validate production capacity using the selected product and workload.

Code

The four references implement the core local state model. Provider annotations and UI controls surround that model; the snippets do not authenticate, provision resources or replace a vendor SDK. Worked saga references assume reliable local compensation.

When to use

Use the scenario to explain access patterns, ownership, failure policy and the operational assumptions behind a cloud service choice.

Interview pitfalls

This is a declared baseline, not every provider product contract. Google Workspace is a Google SaaS example, not a resource inside a GCP project. Actual contract, configuration and business requirements define each responsibility.

Quiz

Explain one concrete outcome, one provider distinction and one unmodeled production concern.
