Azure Integration Services brings together API Management, Logic Apps, Service Bus and Event Grid as a reliable, scalable platform for integrating on premise and cloud based applications, data, and processes across your enterprise.
The four components of Azure Integration Services address the core requirements of application integration, yet real scenarios often require more. Maybe your integration application needs a place to store unstructured data or a way to include custom code that does specialised data transformations. Azure Integration Services is part of the larger Azure cloud platform and supports these features. You might store unstructured data in Azure Data Lake Store for instance, or write custom code using Azure Functions, a serverless compute technology. Azure Integration Services is not an isolated, standalone internet Platform as a Service. Instead, it is part of the larger Azure offering which provides immediate integrated access to any other cloud services you need.
