Why the Salesforce vs Heroku Decision Matters
Discover why choosing the right partner is essential for building scalable architectures.
Salesforce is one of the most powerful platforms for managing customer relationships, automating workflows, and centralizing business data. However, as organizations expand their digital ecosystems, they often encounter use cases that go beyond what the core platform was designed to handle.
When teams begin building customer portals, high-volume integrations, or complex data processing services, a key architectural decision emerges:
Should this solution live directly in Salesforce, or should it be built on Heroku?
Making the incorrect decision can introduce performance issues, scalability limits, and fragile system architectures that become difficult to maintain over time. Understanding when to extend Salesforce with Heroku is critical for building systems that remain stable as organizations grow.
Understanding the Difference Between Salesforce and Heroku
While both platforms are part of the Salesforce ecosystem, they serve different purposes within a modern architecture.
| Platform | Primary Purpose | Key Characteristics |
|---|---|---|
| Salesforce | Manage structured business data and customer relationships | Designed for internal workflows, CRM operations, governance, and secure data management within a highly controlled environment. |
| Heroku | Build and scale custom applications | Cloud platform for developing, running, and scaling custom apps independently while integrating seamlessly with Salesforce. |
Together, they create a powerful architecture where:
- Salesforce acts as the system of record.
- Heroku powers custom applications, APIs, and high-scale services.
When used together strategically, organizations can maintain Salesforce stability while extending their capabilities far beyond the platform’s native limits.
Where Native Salesforce Works Best
Salesforce performs exceptionally well when solutions align with its core strengths.
Native Salesforce development is often the best option when:
- Use cases are primarily internal and workflow-driven
- Data volumes are predictable and manageable
- User interfaces rely on standard Salesforce components
- Performance requirements remain within typical CRM operations
For many business processes, such as sales automation, service management, and internal approvals, staying within the Salesforce platform provides speed, security, and governance.
When Heroku Becomes the Better Choice
Some use cases require more flexibility and the ability to scale and be more dynamic than Salesforce was originally designed to provide. In these scenarios, Heroku becomes a powerful extension.
Organizations often choose Heroku when they need to:
- Build customer-facing or partner-facing applications
- Handle high-volume APIs or integrations
- Process large asynchronous workloads
- Support custom web or mobile experiences
- Integrate Salesforce with multiple external systems
In these architectures, Salesforce remains the central system of record, while Heroku manages the heavy processing, custom logic, and scalable application services.
Common Salesforce Scaling Limits
Salesforce is intentionally designed with governance controls that ensure stability across a multi-tenant platform. While these controls are essential for reliability, they can introduce constraints for certain types of workloads.
Architectural challenges often appear when teams attempt to use Salesforce for:
- High-throughput API services
- Long-running processes
- Large data transformations
- Real-time integrations with multiple external systems
- Custom consumer applications with unpredictable traffic
When these workloads are forced into the core platform, teams may encounter governor limits, slower performance, and increasing technical debt.
How Heroku Extends Salesforce for Scalable Architectures
Heroku helps organizations overcome these challenges by allowing workloads to run outside the core Salesforce environment while remaining fully integrated.
Common patterns include using Heroku to:
- Offload heavy processing workloads
- Run asynchronous background jobs
- Handle traffic spikes and high-volume APIs
- Power custom customer or partner applications
- Integrate multiple external systems through scalable services
This architecture allows Salesforce to remain stable and focused on its strengths while Heroku handles workloads that require greater flexibility.
Best Expert Practices When Combining Salesforce and Heroku
At Oktana, we successfully use Salesforce and Heroku together following a few key architectural principles.
- Keep Salesforce as the system of record: As the trusted source for customer and business data.
- Offload high-volume workloads: Move processing-intensive tasks such as data transformations and asynchronous jobs to Heroku services.
- Design integrations for scalability: Use APIs and asynchronous patterns to ensure systems remain resilient as usage grows.
- Build custom applications outside the core platform: Customer portals, mobile apps, and high-traffic services are often better suited for Heroku.
- Monitor performance across the ecosystem: Observability across both platforms ensures issues can be detected and resolved early.
These practices allow us to maintain Salesforce reliability while expanding their digital capabilities.
How Oktana Approaches Salesforce and Heroku Architectures
Designing the right architecture between Salesforce and Heroku requires more than technical implementation, it requires a deep understanding of how the platforms work together in real-world environments.
At Oktana, Heroku is never treated as a standalone platform. Instead, it is considered a strategic extension of the Salesforce ecosystem. By carefully evaluating system requirements, scalability needs, and integration complexity, teams can design solutions that remain resilient as usage and data volumes grow.
This approach helps avoid common pitfalls such as:
- Performance bottlenecks
- Architectural rework
- Systems that become difficult to maintain over time
When Salesforce and Heroku are used together thoughtfully, they enable organizations to build flexible, scalable solutions while preserving the reliability and governance that make Salesforce such a powerful platform.
If you’re evaluating Heroku, or already running it at scale, engaging a knowledgeable Heroku Partner early can prevent rework and ensure scalable, reliable architectures that integrate seamlessly with Salesforce.
