Azure App Service :

Azure App Service includes the Web App + Mobile App capabilities that we previously delivered separately (as Azure Websites + Azure Mobile   Services).  It also includes powerful new Logic/Workflow App and API App capabilities that we are introducing today for the very first time  – along with built-in connectors that make it super easy to build logic workflows that integrate with dozens of popular SaaS and  on-premises applications (Office 365, SalesForce, Dynamics, OneDrive, Box, DropBox, Twilio, Twitter, Facebook, Marketo, and more).

Logic Apps :

Azure App Service is a fully managed PaaS (Platform as a Service) for developers that makes it easier to build web, mobile, and integration  apps. Logic Apps are a part of this suite and allow any technical user or developer to automate business process execution and workflow  using an easy-to-use visual designer.

Why Logic Apps?

Logic Apps allow developers to design workflows that start from a trigger and then execute a series of steps. Each step invokes an API  whilst securely taking care of authentication and best practices, like checkpointing and durable execution.

Logic App Concepts :

The following are some of the key pieces that comprise the Logic Apps experience.

Workflow – Logic Apps provides a graphical way to model your business processes as a series of steps or a workflow.

Managed APIs – Your logic apps need access to data and services. Managed APIs are created specifically to aid you when you are connecting to and working with your data. See the list of APIs available now in managed APIs.

Triggers – Some Managed APIs can also act as a trigger. A trigger starts a new instance of a workflow based on a specific event, like the arrival of an e-mail or a change in your Azure Storage account.

Actions – Each step after the trigger in a workflow is called an action. Each action typically maps to an operation on your managed or custom API apps.

BizTalk – For more advanced integration scenarios, Logic Apps includes capabilities from Biztalk. Biztalk is Microsoft’s industry leading integration platform. The BizTalk API apps allow you to easily include validation, transformation, rules, and more in to your Logic App workflows.
