Exam Topics
Exam Tips
- 1Heroku Architecture is 30%—know dynos, add-ons, buildpacks, and scaling strategies.
- 2Understand scaling and performance: horizontal vs vertical scaling, caching, database optimization.
- 3Know security and data: encryption, compliance, data residency.
- 4Be ready for "how would you architect X on Heroku?" questions.
Prerequisites
- •Heroku development experience
- •Architect-level knowledge
Focus Areas
- •Heroku Architecture
- •Scaling and Performance
- •Security and Data
- •Integration
Study Strategy
Design Heroku-based solutions.
Understand dyno types, scaling strategies, and add-ons.
Practice explaining architectural decisions for cloud-native apps.
Exam Format and First-Attempt Readiness
The Salesforce Certified Heroku Architect exam has 60 questions in 105 min, passing score ~63%. Most Salesforce exams test scenario-based decisions — focus on when to use each feature, not just terms.
- Study Heroku Architecture and Scaling and Performance first — together they carry 55% of the exam.
- Do timed question sets. Build pacing and confidence.
- Review why wrong answers are wrong. It improves scenario reasoning.
- Book the exam once your mock scores are steady above ~63%.
Is the Heroku Architect Exam Hard?
Is the Heroku Architect Exam Hard?
The Heroku Architect exam is hard. It rewards practical Salesforce experience because many questions ask you to choose the best configuration, design, or troubleshooting approach rather than recall isolated definitions.
- 60 questions in 120 min.
- ~68% passing score — build a margin above the minimum before booking.
- Scenario-based choices — expect questions that test when to use Heroku, Scalability, or Deployment.
- Hands-on context matters — candidates who have configured or supported Heroku in a real org are better prepared than candidates who only memorize notes.
Pass Rate Guidance
Aim for 75%+ on timed practice sets before booking. If your score is below that, review the highest-weight topics first and retake questions until you can explain why each wrong option is wrong.

How Many Questions Are Scenario-Based?
A meaningful share of questions are scenario-based. The common pattern is a business requirement followed by several plausible Salesforce options; your job is to identify the safest, most maintainable choice for Heroku.
Best Way to Pass on Your First Attempt
- Start with the official outline: Map each exam objective to your notes, Trailhead practice, and weak areas before taking full mocks.
- Prioritize high-impact topics: Spend extra time on Heroku, Scalability, and Deployment because these usually drive the hardest scenario questions.
- Practice under time pressure: Use timed question sets so you learn when to move on and return to marked questions later.
- Review explanations deeply: Do not just memorize the right option; write down why the other options are less appropriate for the scenario.
Heroku Architect: Key Concepts for the Exam
Heroku Platform Architecture & Dynos
Heroku runs applications in lightweight Linux containers called Dynos. Dyno types: Web (handles HTTP traffic), Worker (background jobs, no HTTP), One-Off (manual or scheduled tasks). Dyno sizes range from Eco (shared, sleeps after 30 min) to Performance-XL (dedicated, high memory). The Dyno Manager restarts crashed dynos automatically. Horizontal scaling adds more dynos of the same type; vertical scaling changes the dyno size. The Procfile defines process types and start commands. The Router load-balances requests across web dynos (round-robin with session stickiness disabled by default). The architect exam tests how to size and scale a Heroku deployment for a given traffic and processing profile.
Data Services: Heroku Postgres & Redis
Heroku Postgres is the primary managed database — available in Essential (row limits), Standard, Premium, and Private tiers. Connection pooling via PgBouncer reduces database connection overhead. Follow databases provide read replicas for analytics queries. Continuous protection (WAL archiving) enables point-in-time recovery. Heroku Data for Redis handles caching, session storage, and pub/sub messaging. Redis plans: Mini (non-persistent) to Premium (persistent, HA). Heroku Key-Value Store (Redis) replaces legacy Heroku Redis. The exam tests data tier selection for a given durability, availability, and performance requirement, and how to configure read replicas for a high-read workload.
CI/CD, Review Apps & Release Management
Heroku Pipelines define promotion stages: Development → Staging → Production. Review Apps automatically deploy pull requests to ephemeral apps for testing — each PR gets its own URL. Heroku CI runs automated tests on each push and blocks promotion on failure. The `heroku pipelines:promote` command promotes a slug (compiled app image) from one stage to the next without rebuilding. Release Phase runs migration scripts or data seeding commands before each new release goes live. Rollbacks revert to a previous release slug instantly. Config Vars (environment variables) are separate per stage, preventing accidental production config in staging. The exam tests how to design a pipeline for a team with multiple parallel feature branches.
Security, Compliance & Private Spaces
Heroku Private Spaces run Dynos and data services inside a dedicated, isolated network environment — required for compliance workloads (HIPAA, PCI, SOC 2). Private Spaces connect to Salesforce orgs via Salesforce Private Connect (AWS PrivateLink) for secure data exchange without traffic traversing the public internet. Internal Routing restricts apps in a Private Space to only receive traffic from within the space. Shield Private Spaces add encryption at rest and enhanced security controls. Log Drains export Heroku logs to external SIEM or logging systems. Heroku Enterprise provides SSO, audit logs, and team-based access controls. The exam tests Private Space configuration for compliance scenarios and the networking model.
Architecture Patterns for Salesforce + Heroku
Heroku Connect syncs data bidirectionally between Heroku Postgres and Salesforce objects — enabling Heroku apps to read/write Salesforce data without direct API calls. Write acceleration pattern: high-volume writes go to Heroku Postgres first, then Heroku Connect syncs to Salesforce asynchronously, avoiding API rate limits. Event-driven pattern: Salesforce Platform Events trigger Heroku workers via Heroku Connect CDC. Compute-offload pattern: complex calculations (ML inference, image processing) run on Heroku and results are written back to Salesforce. The architect exam tests which pattern to apply for a given scalability, latency, and Salesforce API limit scenario — especially for IoT, mobile, or high-volume data scenarios.
Heroku Connect maps Salesforce objects to Postgres tables and polls both sides on a schedule (or via streaming), writing changes in whichever direction is configured — this lets a Heroku app read/write Salesforce data without direct API calls.
How to Pass the Heroku Architect Exam
The Heroku Architect exam tests enterprise-scale Heroku deployment design. Focus on Heroku infrastructure components, Heroku Connect for Salesforce data sync, high-availability patterns, and security architecture.
Heroku Infrastructure Components
Know dynos (web, worker, one-off), formations, add-ons, buildpacks, and config vars. Understand how these components combine to run a scalable application on Heroku.
Heroku Connect Architecture
Know how Heroku Connect syncs data between Heroku Postgres and Salesforce using polled sync (Salesforce → Postgres) and a Salesforce trigger (Postgres → Salesforce). Understand conflict resolution and sync frequency.
High Availability & Scaling
Understand horizontal scaling (multiple dynos), how the Heroku Router load-balances requests, database connection pooling (PgBouncer), and how to design for zero-downtime deployments.
Security Architecture
Know how to use Private Spaces for network isolation, Heroku Shield for HIPAA/PCI compliance, and how to secure data in transit (TLS) and at rest with encrypted Heroku Postgres.
Performance Optimization
Know how to use Heroku caching (Redis add-on), async job processing (worker dynos with Sidekiq/Celery), and database query optimization to design performant Heroku applications.
