Well-Architected Service Selection
This topic covers Well-Architected pillars, availability, failover, scalability, performance, Cloud Run, GKE, Compute Engine, storage, AI services, and design fit.
How to study for Google Professional Cloud Architect
Treat each item as an architecture tradeoff: identify business drivers, technical constraints, migration dependencies, security controls, reliability targets, and operating model.
Core concepts
Concept 1
Well-Architected Service Selection questions test Google Cloud architecture tradeoffs instead of isolated product recall.
Exam cue: Identify the business driver, workload shape, data path, security boundary, reliability target, and operations model.
Concept 2
The best answer maps business goals to technical requirements, Well-Architected pillars, service fit, security, cost, reliability, and operations.
Exam cue: Choose the Google Cloud pattern that satisfies the stated constraint with the least unnecessary custom operations.
Concept 3
Eliminate options that ignore migration dependencies, resource hierarchy, data movement, network boundaries, compliance, or operational ownership.
Exam cue: Prefer managed, observable, secure, resilient, cost-aware, and automatable designs when requirements support them.
Risk pitfalls and guardrails
Choosing a familiar product before reading the business and technical constraints.
Guardrail: Avoid answers that pick products before reading business needs, compliance, migration dependencies, reliability targets, or operations ownership.
Optimizing for one pillar while ignoring security, reliability, performance, cost, or sustainability.
Guardrail: Avoid answers that pick products before reading business needs, compliance, migration dependencies, reliability targets, or operations ownership.
Skipping migration, deployment, monitoring, or support implications in an architecture scenario.
Guardrail: Avoid answers that pick products before reading business needs, compliance, migration dependencies, reliability targets, or operations ownership.
Memory anchors
Well-Architected Framework
The Google Cloud Well-Architected Framework guides secure, reliable, efficient, cost-optimized, and operationally excellent designs.
High Availability
High availability reduces downtime by removing single points of failure and using resilient service patterns.
Failover
Failover shifts service to healthy capacity when a primary component becomes unavailable.
Cloud Run
Cloud Run runs containerized applications with serverless scaling and managed operations.
GKE
Google Kubernetes Engine manages Kubernetes for containerized workloads that need orchestration control.
Compute Engine
Compute Engine provides virtual machines for workloads that need OS-level control.
Cloud Storage
Cloud Storage stores durable object data with storage classes and lifecycle controls.
BigQuery
BigQuery provides serverless analytics for large-scale structured and semi-structured data.
Gemini Models
Gemini models can support generative AI workloads through Google Cloud AI services.
Service Fit
Service fit matches workload needs to platform control, scaling, cost, and operational responsibility.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Check-up Questions
A team has a stateless HTTP API packaged as a container. Traffic is unpredictable, requests finish within the platform's supported duration, and the team wants no cluster administration. Which compute service is the best fit?
A vendor appliance requires a supported custom kernel module and privileged operating-system access. Which platform should the architect evaluate first?
