- Use Heroku Redis for caching and ephemeral workloads.
- Incorporate add-ons (monitoring, logging, messaging) into platform designs.
- Design backup, restore and disaster-recovery strategies for data services.
🔄 Heroku Connect & Salesforce
- Decide which objects to sync and how frequently.
- Understand Read/Write vs Read-Only mappings and their trade-offs.
- Handle conflict resolution and data-quality issues.
- Design patterns that combine Heroku APIs, Connect and external integrations.
🚀 Pipelines, CI/CD & Collaboration
- Structure pipelines for dev, staging and production environments.
- Leverage review apps for feature validation.
- Connect pipelines with external CI tools for automated testing.
- Manage access and collaboration across teams and environments.
🛡️ Security, Compliance & Operations
- Manage secrets via config vars and secure add-ons.

- Implement logging, monitoring and alerting across all tiers.
- Prepare runbooks and incident-response processes for critical apps.
Where Heroku Architect Fits in Your Journey
There is no enforced pre-requisite path, but many candidates follow something like:
- 1️⃣ Foundation: Solid web application development experience (Node.js, Java, etc.).
- 2️⃣ Platform Skills: Hands-on experience deploying and scaling apps on Heroku.
- 3️⃣ Data & Connect: Projects using Heroku Postgres, Redis and Heroku Connect with Salesforce.
- 4️⃣ DevOps & Ops: Responsibility for pipelines, CI/CD, monitoring and incident response.
- 5️⃣ Exam: Attempt Heroku Architect when you regularly make platform-level decisions.
The goal of the exam is to validate that you can act as a platform architect – not just deploy a single app, but design how Heroku fits into the broader Salesforce and enterprise landscape.
4-Week Study Plan (Adjust to Your Experience)
This plan assumes you already have apps running on Heroku. If you’re newer, extend each week and add more hands-on labs and Trailhead modules.
Week 1 – Understand the Exam & Platform Overview
- Read the official Heroku Architect exam guide thoroughly.
- Review how your current Heroku apps are structured (dynos, buildpacks, regions).
- Study reference architectures for 12-factor apps and Heroku’s runtime model.
- Identify gaps in your knowledge – e.g. certain add-ons, data features or Connect features.
Week 2 – Data Services & Heroku Connect
- Deep dive into Heroku Postgres – plans, HA, followers, backups, performance.
- Experiment with Heroku Redis for caching and background processing.
- Set up a sample project using Heroku Connect to sync Salesforce data.
- Practice designing mappings, sync strategies and conflict-resolution approaches.
Week 3 – Pipelines, CI/CD & Operations
- Configure pipelines with development, staging and production apps.
- Use review apps for pull request validation.
- Integrate CI (e.g. GitHub Actions, CircleCI) to run automated tests on deploy.
- Set up logging, metrics and alerts using Heroku add-ons (or external tools).
Week 4 – Security, Scenarios & Mock Exams
- Review security and compliance considerations for Heroku and connected services.
- Work through scenario-based questions, focusing on trade-offs and justification.
- Document 2–3 “reference architectures” – e.g. API backend, event-driven microservices, Salesforce-sidecar app.
- Take timed practice question sets to simulate the actual exam experience.
Sample Scenario-Style Questions
Question 1
A customer is migrating a monolithic on-premise application to Heroku. The app has sudden, unpredictable spikes in traffic, and the team wants to scale horizontally during these peaks while keeping costs reasonable outside of peak hours. Which approach should the architect recommend?
Question 2
A Salesforce customer wants to build a customer portal on Heroku that displays near real-time Salesforce data and allows customers to update limited information. They also need to run analytics queries on large datasets without impacting Salesforce performance. Which combination best meets the requirement?
Question 3
An enterprise runs multiple mission-critical apps on Heroku. The CISO asks for an architecture that minimizes blast radius between apps, improves network isolation and provides more control over inbound traffic. Which pattern should the Heroku Architect prioritize?
