When we are designing a message-based integration solution, one of the first things we need to define is how the application data are going to be serialised into messages, so they can be transmitted to other applications. The Message Construction Enterprise Integration Patterns provide documented knowledge that can...

Introduction

Azure Logic App is a set of workflow definitions, which is written in JSON format. The nature of JSON object results in this being tightly bound with ARM template. In other words, the Logic App has a dependency on an ARM template. Due to these characteristics, when any update is made on the workflow, the...

Update 2021: An updated version of this post is available on this link. 

Introduction

Azure currently has two service offerings of serverless compute: Azure Logic Apps and Azure Functions. Until recently, one could argue that Azure Functions were code triggered by events while Logic Apps were event-triggered...

In many information system development scenarios, including integration scenarios, handling date/time value is always problematic. If your information systems reside in your office or data centre located in your area, that won’t bring about too much trouble. However, if your organisation runs applications in several...

Introduction

A year ago, I wrote a post about this very same topic, the Microsoft Azure Integration Platform as a Service (iPaaS). At that time, the core iPaaS product offering, Azure Logic Apps, was roughly 6 months old, since it’s generally available launch. Since the launch date, we’ve seen an impressive release...

Introduction

In Azure Logic Apps workflows, you can implement conditions and switch cases to control the flow based on runtime inputs and outputs. This functionality is quite useful, and in many cases, can be used to implement the business rules required. However, those business rules are inherent to the workflow, and...

There are many cases that we need to retrieve access keys and/or endpoints of Azure resources, as soon as they are deployed through ARM templates. Typical uses cases are:

1. To display those values in the outputs section of ARM templates,
2. To get a reference to the outputs section of nested ARM templates from their...

When we work for a service integration project for a customer’s information systems, not all systems use cutting-edge technologies. Rather, still many information systems use legacy ways to get integration works done. For example, some legacy applications still drop files to a designated folder so that other...

While working on an integration project, we came across a very interesting requirement of sequencing file fed to a system based on pre-defined dependencies. This problem was complex because the target system did not want to see a file in S3 bucket (or blob container) unless the system has already processed and...

In a previous post, I showed how to implement Business Activity Monitoring for Logic Apps. However, sometimes developers, ops, or business users want to query execution logs to get information about the processing of business messages. Whether for troubleshooting or auditing, there are some questions these personas...
