Question
You have heard about Azure's Logic Apps. What are they and what do they do?
Answer
Azure Logic Apps are a PaaS solution. Logic Apps execute in response to a triggering event (e.g., recurring on a schedule based on time, receiving a REST API call, or a Tweet being posted). They initiate a variety of different tasks as you can determine the OS architecture (either Windows or Linux) without having to manage that same OS.
Logic Apps are very flexible and powerful. Logic Apps can do many things such as message queueing, monitor Twitter accounts (if you enter your Twitter account's credentials), integrate with SalesForce, or send REST API POST calls with authentication headers.
