Inbound integration refers to the process where external systems provide data or resources to your system. For instance, an app that consumes weather data from an external API exhibits inbound integration. On the contrary, outbound integration involves your system sending data or resources to an external system. A system that sends notification emails is an example of outbound integration.
Designing Azure Inbound Integrations
Azure Logic Apps helps you build powerful integration solutions by connecting your business-critical apps and services eliminating the barriers of compatibility.
Here’s a typical example of using Azure Logic Apps for inbound integration:
Suppose you need to design an app that consumes tweets with a specific hashtag and stores it in an Azure SQL Database.
Using Azure Logic Apps, you can automate this process as follows:
- Create a Logic App that triggers every time a tweet is posted with the selected hashtag.
- Add an action to store the tweet content into SQL server.
The Logic Apps Designer then creates a JSON file to hold the configuration of the tweet and SQL server, connects it with your Azure SQL Server and the Twitter API, and maintains a live connection.
Designing Azure outbound Integration
Similarly, designing outbound integration can be done using Azure Logic Apps. As an example, suppose you want to design a system that sends an email notification whenever a new row is added to an Azure SQL Database. Here is how you can achieve this:
- Create a Logic App that is triggered whenever a new row is added to the precise SQL Server.
- Add an action to send an email through Outlook 365 with the content of the new row.
The Logic Apps Designer creates a JSON file of the configuration of the new row and the email and connects your Azure SQL Server with Outlook 365.
Azure Service Bus for Inbound and Outbound Integrations
Azure Service Bus is another significant tool in Azure used for both inbound and outbound integrations. It serves as a reliable and secure platform for asynchronous data and state transfer.
For Inbound Integration, an external system sends a message to a queue or topic, and your system consumes the message. For Outbound Integration, your system sends a message to a queue or topic, and an external system consumes your message.
The following table gives you a comparison between Azure Logic Apps and Azure Service Bus.
| Azure Logic Apps | Azure Service Bus | |
|---|---|---|
| Complexity | Deals with complex system interactions | For simple system interactions |
| Connection | Connects directly to systems | Needs an endpoint that connects to systems |
| Process | Executes a series of steps or actions | Delivers messages without any additional steps |
| Trigger | Triggers based on system events | Messages are pushed to, or pulled by listeners |
Conclusion
Designing Azure inbound and outbound integrations forms a vital part of the PL-400 exam. Getting hands-on experience with these Azure services will help you grasp the essentials of inbound and outbound integration. Whether it’s about designing a multi-step approval process or simply delivering messages in a decoupled manner, Azure provides all the necessary tools to build and scale these solutions. Explore these services, experiment with different scenarios, and enhance your preparation to ace the exam.
