What is Azure Logic Apps? A plain-English explainer
Azure Logic Apps is Azure’s low-code workflow and integration service: it lets you automate a business process by connecting apps and services together — a new file lands in storage, an approval email goes out, a record gets created in another system — largely by configuring steps visually rather than writing custom integration code for each connection. Each workflow starts with a trigger (something that happens) and runs through a sequence of actions (things it does in response), drawing on a large library of prebuilt connectors to common services. Because so much real-world cloud work is “get these two systems talking to each other” rather than building new applications from scratch, Logic Apps appears in Azure certification study alongside Azure’s other integration services. Here is what a workflow actually is, when it fits, and where it sits next to code-first alternatives.
What workflow and integration automation means
A lot of everyday business software work is not building something new, but making existing systems cooperate: when a customer submits a form, add a row to a spreadsheet and notify a team on chat; when an order is placed, check stock in one system and update a shipping system in another. Doing that by hand, or by writing bespoke code for every connection, is slow and easy to get wrong.
Workflow automation tools solve this by letting you define the sequence — trigger, then actions, possibly with conditions and loops — once, and have the platform run it reliably every time the trigger fires. Logic Apps is Azure’s version of that idea, built specifically around integrating with other services rather than running general-purpose application code.
How a Logic App is put together
Every Logic App workflow has the same basic shape:
- A trigger — the event that starts the workflow: a new email arriving, a file appearing in storage, a scheduled time, or an HTTP request coming in.
- A sequence of actions — the steps that run afterwards: send a notification, call an API, transform some data, write a record to a database.
- Connectors — prebuilt integrations to hundreds of services (Microsoft 365, common SaaS tools, databases, other Azure services) that provide the triggers and actions, so you are configuring a connection rather than writing an API client.
- Conditions and control structures — branching logic, loops and conditions, so a workflow can react differently depending on the data it receives.
Common uses
Typical Logic Apps scenarios include integrating SaaS tools that were never designed to talk to each other directly, running event-driven automation in response to something happening elsewhere in Azure (a file upload, a message on a queue), and orchestrating a sequence of steps across multiple systems — an approval process, an onboarding flow, a data-synchronisation job between two platforms. The common thread is connecting existing systems and automating what happens between them, rather than building a new standalone application.
Logic Apps versus code-first orchestration
It is worth being careful here, since Logic Apps is sometimes mentioned in the same breath as services like AWS Step Functions, which also orchestrate multi-step workflows. The comparison holds only loosely: Step Functions orchestrates the flow between your own application code and AWS services, and workflows are typically defined and versioned as part of a codebase by developers. Logic Apps leans lower-code and integration-focused — its main strength is the breadth of prebuilt connectors to third-party and Microsoft services, aimed at a wider range of people building integrations, not only developers writing orchestration code. Both provide visual workflow definitions and both are serverless, but Logic Apps’ centre of gravity is “connect these services together”, while Step Functions’ is “coordinate my own application logic”.
How you pay for it, without the numbers
Logic Apps follows the pay-for-use model common across serverless integration services: cost is generally driven by how many actions and connector calls a workflow executes, rather than a fixed platform fee. Exact pricing, plan types and connector tiers change over time, so this article deliberately avoids listing them — check Microsoft’s official Logic Apps pricing page for current detail. The concept worth keeping is that a workflow only costs something when it actually runs, in line with how most serverless services are billed.
Where Logic Apps appears in certification study
Logic Apps is part of Azure’s integration services, covered at a foundational level in Azure Fundamentals (AZ-900) alongside Azure’s other automation and integration tools. Azure Administrator Associate (AZ-104) goes further, covering deploying and managing Logic Apps resources as part of broader Azure management responsibilities.
This article covers what Logic Apps is and why it exists — designing specific connectors, control structures and error-handling within a workflow belongs in the syllabus itself, which our /revision study library breaks down lesson by lesson for these certifications.
