The Google Professional Cloud Architect (PCA) certification is one of the most respected cloud architecture credentials. It tests your ability to design, plan and manage secure, scalable and reliable solutions on Google Cloud — with a strong focus on business requirements and case studies.
Who should take the PCA?
- Cloud architects and senior cloud engineers
- Consultants designing Google Cloud solutions for clients
- AWS or Azure architects expanding to multi-cloud
- Engineers who have passed the Associate Cloud Engineer
Google recommends several years of industry experience, including at least one year designing on Google Cloud.
Exam overview
The PCA is a two-hour exam with multiple-choice and multiple-select questions, including questions based on published case studies. Google publishes the case studies in advance, so you can study them before the exam.
Exam details such as price, length and question count change periodically — always confirm current information on the official certification page before you book.
Exam sections
- Designing and planning a cloud solution architecture
- Managing and provisioning infrastructure
- Designing for security and compliance
- Analyzing and optimizing technical and business processes
- Managing implementation
- Ensuring solution and operations reliability
Study the case studies deeply
Case studies describe fictional companies with business and technical requirements. For each one:
- List business goals, technical requirements and constraints
- Sketch a reference architecture
- Identify which services fit each requirement
- Consider migration, security, compliance and cost
Many questions test whether you choose the solution that best fits the stated requirements — not simply the most advanced technology.
Key design topics
- Choosing compute: Compute Engine, GKE, Cloud Run, App Engine and Cloud Functions
- Choosing storage and databases: Cloud Storage, Cloud SQL, Spanner, Bigtable, Firestore and BigQuery
- Networking: Shared VPC, hybrid connectivity (Cloud VPN, Interconnect), load balancing and private access
- Security: IAM, organization policies, VPC Service Controls, encryption and key management
- Reliability: regional vs. multi-regional designs, SRE practices, backups and disaster recovery
- Migration strategies and modernization
- Cost optimization: committed use discounts and right-sizing
A study plan
- Review the exam guide and case studies
- Refresh core services through Google Cloud Skills Boost courses and labs
- Read Google Cloud’s Architecture Framework and reference architectures
- Practice designing solutions on paper for each case study
- Take practice exams and review explanations thoroughly
Allow six to ten weeks if you already have cloud experience.
Exam tips
- Read the requirement keywords: “minimize cost,” “global users,” “regulatory compliance,” “minimal changes”
- Prefer managed services when they meet requirements
- Watch for answers that technically work but violate a stated constraint
- Manage your time on long case-study questions
