Logic Apps is a service offered by Microsoft Azure which promotes the serverless architecture design. Anyone can use Logic Apps to create, edit and deploy cloud-based integrations and workflows. It requires minimal effort in development / deployment, in comparison to other on-premise integration tools such as Microsoft BizTalk server, where the development to deployment time is very high. Microsoft is investing heavily in this new technology and introducing many connectors to suit the demands of the growing integration industry.
Logic Apps is a fully-managed service with no infrastructure requirements. The aim of this technology is to reduce the time from development to production, drastically. There are many ready made components with predefined functionality, that the developers can use to achieve desired results. This means that there is no need to write a single line of code to achieve your integration as you can use pre-defined components.
