Definition
Heroku is a cloud application platform (PaaS) owned by Salesforce that lets developers build, deploy, and scale applications using popular languages like Node.js, Python, Ruby, Java, and Go. Heroku integrates with Salesforce through Heroku Connect, enabling bidirectional data sync between Heroku Postgres databases and Salesforce objects.
Real-World Example
A real estate company builds a public-facing property search website on Heroku using Node.js and React. Heroku Connect syncs property listings from Salesforce to a Heroku Postgres database, so the website queries fast local data instead of making API calls to Salesforce. When a visitor submits an inquiry form, the data flows back into Salesforce as a Lead record.
Why Heroku Matters
Heroku is a cloud Platform-as-a-Service (PaaS) owned by Salesforce that enables developers to build, deploy, and scale web applications using popular programming languages like Node.js, Python, Ruby, Java, and Go. Unlike the Salesforce platform which uses proprietary languages like Apex, Heroku provides standard developer tooling and hosting for customer-facing applications, APIs, and microservices. The key connector between Heroku and Salesforce is Heroku Connect, which provides bidirectional data synchronization between Heroku Postgres databases and Salesforce objects, enabling real-time or near-real-time data flow without custom API integration code.
As organizations scale their Salesforce implementations, they frequently encounter use cases that exceed the platform's capabilities - public-facing websites with millions of visitors, complex data processing pipelines, or applications requiring specific programming languages and frameworks. Heroku fills this gap by providing a scalable application platform that keeps data connected to Salesforce. Without Heroku or a similar external platform, organizations either force-fit everything into Salesforce (hitting governor limits and performance constraints) or build disconnected applications that create data silos. Heroku's auto-scaling dynos handle traffic spikes, its add-ons ecosystem provides services like Redis caching and Elasticsearch, and Heroku Connect eliminates the integration burden that typically accompanies external application development.
How Organizations Use Heroku
- Crestview Real Estate — Crestview Real Estate built a public property search website on Heroku using Node.js and React. Heroku Connect syncs property listings from Salesforce to a Heroku Postgres database, so the website queries fast local data instead of making API calls to Salesforce. When visitors submit inquiry forms, the data flows back into Salesforce as Lead records automatically.
- Streamline Commerce — Streamline Commerce uses Heroku to host a customer-facing order tracking portal that handles 50,000 daily visitors. The portal reads order status from a Heroku Postgres database synced via Heroku Connect, insulating Salesforce from the traffic load while keeping data synchronized in near-real-time.
- DataPulse Analytics — DataPulse Analytics runs Python-based machine learning models on Heroku that process Salesforce data synced through Heroku Connect. The models generate churn prediction scores that are written back to Salesforce Contact records, giving the customer success team AI-driven insights without requiring Einstein AI licenses.
