Overview of Salesforce Integration Architecture

Why Do You Need Integration with Salesforce?

Integrating different systems within your Salesforce implementation or projects is essential for a comprehensive approach to managing business processes. Although Salesforce is a powerful platform capable of handling a wide range of tasks related to sales, marketing, customer support, and analytics, it cannot fulfill every business need on its own.

For instance, integrating Salesforce with an accounting system is a common practice. This integration allows businesses to automatically generate invoices in the accounting system when an opportunity is marked as closed won in Salesforce. Similarly, integrating Salesforce with a company’s proprietary system or external services like DocuSign enables the seamless transfer of customer signup data and usage information directly into Salesforce.

Such integrations not only streamline separate processes but also enhance the efficiency and effectiveness of business operations. The foundation of these integrations is typically an Application Programming Interface (API), which facilitates communication between different software applications. Salesforce, being at the forefront of cloud computing, offers a variety of standard APIs that enable these integrations through various methods.

Types of Integration Architectures

Understanding the architecture behind system integrations is crucial for selecting the most suitable approach for your project. There are three primary architectures commonly used in the field:

Point-to-Point Integration

This architecture involves direct connections between systems, where each system communicates with another through a one-to-one relationship. While this may seem straightforward, it becomes complex and costly as the number of integrations increases. Each new system added requires a new set of integrations, making maintenance and scalability challenging. Despite its simplicity, the lack of standardization can lead to performance inconsistencies.

Hub and Spoke Integration

To mitigate some of the drawbacks of point-to-point integrations, the hub and spoke model introduces a centralized hub that manages communication between systems. This reduces the number of direct connections required, as each system connects to the hub, which then routes messages to the appropriate destination. This model improves upon the scalability and maintenance issues of point-to-point integration but introduces a single point of failure. If the hub experiences issues, all communication can be disrupted.

Enterprise Service Bus (ESB)

The ESB architecture evolves from the hub and spoke model by offering a more flexible and robust integration framework. It decouples systems entirely, eliminating a single point of failure and enhancing scalability. Systems communicate through the ESB, which handles routing, transformation, and orchestration of messages. Salesforce’s MuleSoft is an example of an ESB, demonstrating its capabilities in integrating disparate systems seamlessly.

Insight:

Each architecture has its own set of pros and cons, and the choice among them depends on specific project requirements such as scalability, complexity, and resilience to failures. Understanding these architectures is fundamental to planning and implementing effective integrations that align with your organizational needs.

Salesforce Integration Capabilities

Salesforce, a pioneer in cloud computing, has always emphasized the importance of integration, making its platform exceptionally open and adaptable. Since the release of its first API in 2000, Salesforce has developed a robust set of APIs and features to support various integration scenarios, ensuring that businesses can connect Salesforce with other systems in multiple ways. Here are the key Salesforce integration capabilities:

REST API: Primarily designed for web and mobile applications, the Salesforce REST API facilitates database operations like querying (GET), creating (POST), and updating (PUT) records. It operates synchronously, making it ideal for scenarios where immediate feedback on the success of an operation is necessary.
SOAP API: Although it may be considered older technology, the SOAP API is reliable for legacy integrations. It’s known for being secure and comprehensive but can be slower and more bandwidth-intensive compared to REST. The SOAP API operates asynchronously, suitable for processes that don’t require instant feedback.
Bulk API: For operations involving large volumes of data (up to 100 million records per 24 hours), the Bulk API is the go-to choice. It supports asynchronous processing, allowing for large-scale data manipulations either in serial or parallel modes, enhancing efficiency and scalability.
Streaming API: When real-time data synchronization between Salesforce and external systems is needed, the Streaming API provides a solution. It enables external systems to subscribe to certain events in Salesforce and receive notifications as soon as data changes occur, facilitating near-instant integration.
Outbound Messages: For scenarios that prefer configuration over coding, outbound messages offer a straightforward integration method. By sending SOAP-based messages from Salesforce to external systems, including field data for further processing, this feature supports asynchronous communication while ensuring the receiving system acknowledges the message.
Web Service Callouts: Salesforce can initiate outbound integrations to external systems through web service callouts. This capability is particularly useful for verifying data with external databases directly from Salesforce, with Salesforce acting as the initiator of the call.
Salesforce Connect: This paid feature allows for data virtualization, where external data can be viewed within Salesforce without actual data storage. It’s an effective solution for accessing large datasets from external systems within Salesforce, optimizing performance and data storage.
MuleSoft: As part of Salesforce’s suite of products, MuleSoft offers a comprehensive integration platform that unifies APIs, integrations, and systems, facilitating complex integration scenarios across various applications and data sources.
Heroku: Another Salesforce integration service, Heroku, provides a platform-as-a-service (PaaS) environment for building and deploying custom applications. Heroku Connect enables seamless integration between Salesforce and Heroku applications, expanding the possibilities for custom application development and data synchronization.

Salesforce’s integration capabilities are extensive, offering various methods to suit different integration needs, from simple data synchronization to complex, real-time data processing. Understanding these capabilities is essential for leveraging Salesforce’s full potential in connecting and automating business processes across different systems.

Salesforce Integration Direction

Any Salesforce integration can be in two directions: inbound integration or outbound Integration, where Inbound integration is an external system initiates contact with Salesforce, while outbound integration is the type of connection, when Salesforce initiates contact with an external system. You may understand the concept better by viewing the image above.

Integration Patterns in Salesforce

When planning a Salesforce integration, it’s vital to consider various factors like the integration type, data volume, timing, and direction to determine the most appropriate method and pattern for your needs. Integration patterns provide a structured approach to solving common integration problems, guiding how different systems interact with one another. Salesforce recommends several key patterns, each suited to specific scenarios:

Remote Call-In: This pattern is used when an external system needs to create, retrieve, update, or delete data in Salesforce. For instance, an order management system might update Salesforce with the latest order status. This pattern is crucial for ensuring that Salesforce remains synchronized with external business processes.
Request and Reply: Salesforce initiates a process in an external system and waits for it to complete before continuing. This synchronous interaction is necessary when the result of the external process directly impacts the next steps in Salesforce, like verifying a billing address via an external service.
Fire and Forget: In this asynchronous pattern, Salesforce triggers an action in an external system but does not wait for the process to complete. The external system acknowledges the request, allowing Salesforce to continue its processes without delay. This pattern is useful for tasks that are not time-sensitive, such as logging activity data.
Batch Data Synchronization: This pattern is applied when large volumes of data need to be synchronized between Salesforce and an external system periodically. It allows for the efficient updating of records in bulk on a scheduled basis, keeping both systems in alignment.
UI Update Based on Data Changes: When changes in Salesforce data need to reflect immediately on the user interface, this pattern ensures that users have access to the most current information. It’s particularly useful in customer service scenarios, where agents must have up-to-date case status information.
Data Virtualization: This pattern involves displaying external system data within Salesforce without physically storing it in Salesforce. It’s beneficial for accessing large datasets in real time without impacting Salesforce’s storage limits or performance. Salesforce Connect often utilizes this pattern to present external data seamlessly within Salesforce interfaces.

These patterns form the foundation of effective integration strategies, enabling Salesforce professionals to choose the most appropriate solutions for their specific project requirements. By understanding and applying these patterns, you can ensure that your Salesforce integrations are efficient, scalable, and tailored to your business needs.
