What is the difference between System Architect and Application Architect?

System Architect focuses on infrastructure and technical architecture domains: integration, data architecture, identity and access management, sharing and visibility, and development lifecycle. Application Architect focuses on application-layer design: advanced administration, platform development (PD1), data modelling, and sharing design. System Architect is more infrastructure-and-platform-focused; Application Architect is more application-layer-and-code-focused.

Which should I pursue first: System Architect or Application Architect?

Most candidates start with Application Architect — the component exams (Advanced Administrator, Platform Developer I) are more accessible, better-resourced for study, and cost $200 each rather than $400. Application Architect builds the application-layer foundation before tackling the deeper infrastructure domains of System Architect. Candidates with strong integration or security backgrounds may find System Architect domain exams more natural to start with.

How much does it cost to earn both credentials?

Minimum cost to earn both credentials (passing each exam once): Application Architect ~$1,200 (ADV Admin $200 + PD1 $200 + Data Architect $400 + Sharing & Visibility $400) + System Architect additional unique exams ~$1,200 (Integration Architect $400 + IAM Architect $400 + Dev Lifecycle $400) = approximately $2,400 total. Note: Data Architect and Sharing & Visibility Architect count toward both credentials — you only pay for them once.

Are both credentials required for the CTA?

Yes — both the System Architect credential AND the Application Architect credential must be held before applying for the Salesforce Certified Technical Architect (CTA) Board Review. You cannot apply for CTA with only one of the two credentials. Both must be in Active status at the time of CTA application.

Do overlapping exams count toward both credentials?

Yes — the Data Architect exam and the Sharing & Visibility Architect exam appear in both credential requirements. Passing either exam once automatically counts toward both Application Architect and System Architect credentials. This overlap reduces the total unique exams needed from nine to seven for candidates pursuing both credentials and the full CTA path.
