Migration and Architecture Decisions: Core Concepts for Cloud Computing Fundamentals

Build the mental model

Migration and Architecture Decisions focuses on this learner need: Choose cloud services by responsibility, workload shape, availability, scaling, data, security, governance, and cost rather than by product names alone. Use shared-responsibility boundaries, regions/zones, virtual networks, compute, object/block storage, managed databases, IAM policies, monitoring, scaling, cost, governance, and architecture tradeoffs.

Track the changing state and identify the evidence that makes that state observable.

Identify the parts and boundaries

In Migration and Architecture Decisions, iaaS/PaaS/SaaS responsibility split. Compute and scaling model. Use shared-responsibility boundaries, regions/zones, virtual networks, compute, object/block storage, managed databases, IAM policies, monitoring, scaling, cost, governance, and architecture tradeoffs.

1. 1

   IaaS/PaaS/SaaS responsibility split.

2. 2

   Compute and scaling model.

3. 3

   Identity/network/data controls.

4. 4

   Cost, resilience, governance, and migration tradeoffs.

Trace one concrete case

Choose one realistic input for Migration and Architecture Decisions and trace it using this path lens: Use shared-responsibility boundaries, regions/zones, virtual networks, compute, object/block storage, managed databases, IAM policies, monitoring, scaling, cost, governance, and architecture tradeoffs. Predict the result before running the example, then compare prediction with evidence.

If the prediction fails, identify the assumption before changing the implementation.

MIGRATION AND ARCHITECTURE DECISIONS
====================================
1. IaaS/PaaS/SaaS responsibility split.
2. Compute and scaling model.
3. Identity/network/data controls.
4. Cost, resilience, governance, and migration tradeoffs.
Evidence: the module-specific command, output, test, rendered state, query result, log, or measurement that proves the exercise worked

Read the concept map, predict one concrete result, then compare that prediction with the module example or native tool.

A module-specific concept trace connecting core decisions to observable evidence.

Compare a nearby alternative

For Migration and Architecture Decisions, compare the shown mechanism with a nearby alternative. Use this technical point—Identity/network/data controls.—inside this path context: Use shared-responsibility boundaries, regions/zones, virtual networks, compute, object/block storage, managed databases, IAM policies, monitoring, scaling, cost, governance, and architecture tradeoffs.

State the tradeoff in your own words.

Explain it back with evidence

Summarize Migration and Architecture Decisions without reading the example. Explain the input or state, operation or decision, and result through this implementation lens: Use shared-responsibility boundaries, regions/zones, virtual networks, compute, object/block storage, managed databases, IAM policies, monitoring, scaling, cost, governance, and architecture tradeoffs.

For Migration and Architecture Decisions, use this evidence standard: the module-specific command, output, test, rendered state, query result, log, or measurement that proves the exercise worked. Interpret the evidence through this path context: Use shared-responsibility boundaries, regions/zones, virtual networks, compute, object/block storage, managed databases, IAM policies, monitoring, scaling, cost, governance, and architecture tradeoffs.

Common mistakes to avoid

• Shared-responsibility assumption wrong.
• Scale target without load metric.
• Public exposure or broad identity permission.
• Migration ignores data/latency/egress cost.
