Well-Architected Framework review in GCP - Commands & Configuration

Introduction

When building systems in the cloud, it is easy to make mistakes that cause problems later. The Well-Architected Framework helps you check your system to make sure it is reliable, secure, efficient, and cost-effective.

When you want to check if your cloud setup follows best practices for security and reliability

When you plan to build a new application and want to design it well from the start

When you notice your cloud costs are higher than expected and want to find savings

When you want to improve your system's ability to handle failures without downtime

When you want to make sure your system protects user data and privacy

Commands

This command starts a new Well-Architected Framework review for your project to check its design against best practices.

Terminal

gcloud beta wellarchitected reviews create --display-name=my-review --project=my-project

Expected Output

Created Well-Architected Review [my-review] for project [my-project].

→

--display-name - Sets a friendly name for the review

→

--project - Specifies the GCP project to review

This command lists all Well-Architected Framework reviews done for your project so you can see their status.

Terminal

gcloud beta wellarchitected reviews list --project=my-project

Expected Output

NAME       DISPLAY_NAME  STATE

my-review  my-review     COMPLETED

→

--project - Specifies the GCP project to list reviews for

This command shows detailed results of the review, including any issues found and recommendations.

Terminal

gcloud beta wellarchitected reviews describe my-review --project=my-project

Expected Output

Name: my-review

Project: my-project

State: COMPLETED

Summary:

- Reliability: PASS

- Security: WARNING

- Cost Optimization: PASS

- Operational Excellence: PASS

- Performance Efficiency: PASS

Recommendations:

- Improve IAM roles to follow least privilege principle.

→

--project - Specifies the GCP project

Key Concept

If you remember nothing else from this pattern, remember: The Well-Architected Framework review helps you find and fix design problems early to build better cloud systems.

Common Mistakes

Not specifying the correct project ID when running review commands

The commands will run on the wrong project or fail, giving no useful results

Always use the --project flag with your actual GCP project ID

Skipping the review describe step and not checking recommendations

You miss important advice that can improve your system's security and reliability

Always run the describe command to see detailed findings and act on them

Summary

Use gcloud commands to create, list, and describe Well-Architected Framework reviews for your GCP projects.

Creating a review checks your cloud setup against best practices in security, reliability, cost, and more.

Describing a review shows detailed results and recommendations to improve your system design.

Practice

1. Which of the following is NOT one of the five pillars of the GCP Well-Architected Framework?

easy

A. Security

B. Reliability

C. Creativity

D. Cost Optimization

Solution

1. Step 1: Recall the five pillars of the Well-Architected Framework

   The five pillars are Security, Reliability, Performance Efficiency, Cost Optimization, and Operational Excellence.

2. Step 2: Identify the option that is not part of these pillars

   Creativity is not one of the five pillars.

3. Final Answer:

   Creativity -> Option C

4. Quick Check:

   Five pillars exclude Creativity [OK]

Hint: Remember the five pillars; anything outside is incorrect [OK]

Common Mistakes:

• Confusing Performance Efficiency with Creativity
• Thinking Creativity is a pillar
• Mixing up Operational Excellence with Creativity

2. Which GCP service is primarily used to monitor and improve the reliability pillar in the Well-Architected Framework?

easy

A. Cloud Storage

B. Cloud Monitoring

C. Cloud Functions

D. Cloud Pub/Sub

Solution

1. Step 1: Understand the role of Cloud Monitoring

   Cloud Monitoring helps track system health and uptime, which directly supports reliability.

2. Step 2: Match the service to the reliability pillar

   Cloud Monitoring is designed to monitor and alert on system reliability issues.

3. Final Answer:

   Cloud Monitoring -> Option B

4. Quick Check:

   Monitoring = Reliability tool [OK]

Hint: Monitoring tools support reliability checks [OK]

Common Mistakes:

• Choosing Cloud Storage which is for data storage
• Selecting Cloud Functions which is for serverless compute
• Picking Cloud Pub/Sub which is for messaging

3. Consider this snippet of a GCP infrastructure review checklist:
{"Security": "High", "Reliability": "Medium", "Cost Optimization": "Low"}
What does this output indicate about the system's cost management?

medium

A. Cost management needs improvement

B. Cost management is excellent and well optimized

C. Cost management is not evaluated

D. Cost management is irrelevant

Solution

1. Step 1: Analyze the cost optimization value

   The value for Cost Optimization is "Low", indicating poor performance in this area.

2. Step 2: Interpret what "Low" means for cost management

   Low means the system is not managing costs well and needs improvement.

3. Final Answer:

   Cost management needs improvement -> Option A

4. Quick Check:

   Low cost optimization = needs improvement [OK]

Hint: Low rating means improvement needed [OK]

Common Mistakes:

• Assuming Low means good
• Ignoring the cost optimization field
• Confusing Low with Medium or High

4. You have a GCP deployment that fails to recover quickly from outages. Which pillar of the Well-Architected Framework is most likely not well implemented?

medium

A. Operational Excellence

B. Security

C. Cost Optimization

D. Reliability

Solution

1. Step 1: Understand the meaning of recovery from outages

   Recovery from outages relates to system availability and fault tolerance.

2. Step 2: Identify the pillar focused on availability and fault tolerance

   The Reliability pillar ensures systems recover quickly and remain available.

3. Final Answer:

   Reliability -> Option D

4. Quick Check:

   Recovery issues = Reliability problem [OK]

Hint: Recovery speed relates to reliability pillar [OK]

Common Mistakes:

• Confusing Security with recovery
• Choosing Cost Optimization which is about cost
• Selecting Operational Excellence which is about processes

5. A company wants to improve their cloud system's security and cost efficiency simultaneously. According to the Well-Architected Framework, which two pillars should they focus on together to achieve this?

hard

A. Security and Cost Optimization

B. Reliability and Performance Efficiency

C. Operational Excellence and Reliability

D. Performance Efficiency and Security

Solution

1. Step 1: Identify pillars related to security and cost

   Security pillar focuses on protecting data and systems; Cost Optimization focuses on managing expenses.

2. Step 2: Match the pillars that address both goals

   Focusing on Security and Cost Optimization together addresses both security and cost efficiency.

3. Final Answer:

   Security and Cost Optimization -> Option A

4. Quick Check:

   Security + Cost Optimization = Both goals met [OK]

Hint: Match goals to pillars directly: security and cost [OK]

Common Mistakes:

• Mixing unrelated pillars
• Choosing only one pillar
• Confusing Performance Efficiency with cost
