These service models differ in what the provider manages and what the customer configures. Compare actual service contracts rather than assuming the labels settle every responsibility.
Before you begin
Understand a basic web application's components. Use diagrams or an authorized sandbox with a defined resource and cost boundary.
Work through the idea
Separate assumptions from service guarantees and check the documentation for the actual service selected. Identify ownership of access, data and operations. Plan what happens when a dependency fails or an expected resource is absent. Use non-sensitive sample configuration rather than real credentials in the exercise.
- Identify the managed layers
- Assign application and identity duties
- Consider portability and cost
Practice task
Compare a fictional hosted CRM, application platform and rented virtual server.
Check your result
Create a responsibility table for patching, application code, access and data.
A mistake to avoid
Do not assume that using SaaS removes responsibility for user permissions or data use.
Keep a review note
Save the inputs or scenario, your reasoning and the result you checked. Explain one assumption and one case that needs more work. Revise the exercise after feedback and distinguish what you demonstrated from what remains untested.
