Azure Logic Apps are an integration service used to create workflows that connect applications, data, and services. They provide a visual workflow designer to define business processes like sending emails or reading files from SFTP, enabling quick and easy integration without extensive coding.
Key terminologies include: Logic App (the service itself), Workflow (the integration pattern within a Logic App), Trigger (the event that starts the workflow, either event-based or time-based), Actions (the steps or processes within the workflow that define business logic), Operators (built-in functions to manipulate data), Connectors (built-in capabilities to connect to various applications and services). Connectors are either 'managed' (some cost involved) or 'built-in' (free and highly scalable).
A practical example demonstrates a flight booking workflow. If a flight booking is below a certain amount (e.g., £1000), it's approved automatically. If it exceeds £1000, it requires managerial approval, with options to approve, reject, or escalate. Logic Apps can visually represent and execute such complex, multi-step business processes, providing clear visibility into each step's execution status.
Logic Apps offer two tiers: Consumption and Standard. Consumption is a pay-as-you-go, fully managed (PaaS) service, ideal for learning or single workflows, but data residency is only guaranteed with Integration Service Environment (ISE). Standard tier, powered by an App Service Plan, supports multiple workflows within a single Logic App, offers high scalability, and guarantees data residency within the specified region. Standard is recommended for production environments.
