Introduction to Microsoft Power Platform for developers

Microsoft Power Platform is a low-code platform for rapidly building customized end-to-end business solutions. It consists of four product areas: Power Apps, Power Automate, Power BI, and Power Pages. Each area can be used individually or together. United by the underlying Microsoft Dataverse technology, all areas are designed for a connected experience to achieve your business goals, whether it's creating analytics, process automation, or data-driven productivity applications.

The platform's low-code approach enables everyone in an organization—from frontline workers to professional developers—to participate in the development of business solutions that drive positive business outcomes. Developers can collaborate with citizen developers to enhance business solutions and solve complex requirements by using the platform's various extension capabilities with code. Thanks to a native integration with Azure, developers can use their cloud development skills to extend Microsoft Power Platform with different Azure services. With a low-code integrated development approach, business goals can be achieved faster and frees up time for the developers.

As a developer interacting with the platform, it's important to understand the basics of what the platform offers. In the following, you'll find a high-level overview of each of the core product areas and their key extensibility points.

Power Apps

Apps created with Power Apps can be shared with internal users and can be run in a browser or on a mobile device. You can create following types of apps: canvas and model-driven.

Canvas apps

Provides the Power Apps maker with complete control over the pixel-perfect screen contents and navigation between multiple screens. Canvas applications use different connectors to work with data and services. Canvas applications can be embedded into SharePoint, Teams, Power BI, and Dynamics 365 applications.

Key developer extensibility points

Build custom UI components using Power Apps component framework

Create custom connectors to communicate to your external data sources and services. A custom connector is a wrapper around a REST API and can be created using tools like Azure Functions and Azure API Management

Model-driven apps

Data-driven applications that are built on top of Microsoft Dataverse. Other data sources and services can be used by model-driven applications by embedding a canvas application.

Key developer extensibility points

Build custom UI components using Power Apps component framework

Implement client business logic using JavaScript and the client API

Build HTML web resources

Power Automate

Power Automate is used to automate tasks and orchestrate activities across various services that use integrated or custom connectors. Using Power Automate you can create cloud flows or desktop flows.

Type	Description
Cloud flows	Can be triggered manually, configured to run when specific events occur, such as when a record is created, or scheduled to run at a specific time. Power Automate is built on top of Azure Logic Apps but offers unique integration with Microsoft Power Platform.
Desktop flows	Used to automate repetitive interactive tasks on the web or the desktop.

Key developer extensibility points

Create custom connectors to communicate to your external data sources and services. A custom connector is a wrapper around a REST API and can be created using tools like Azure Functions and Azure API Management

Use workflow definition functions to build complex expressions

Power BI

Power BI is Microsoft's business analytics solution that provides interactive data visualization BI tools to help users visualize and share data and insights across their organization.

Key developer extensibility points

Embed Power BI in apps, websites, and portals

Create custom visuals using the open-source SDK

Power Pages

Power Pages is a secure, enterprise-grade, low-code software as a service (SaaS) platform for creating, hosting, and administering modern external-facing business websites. Low-code makers can rapidly design, configure, and publish websites that seamlessly work across web browsers and devices. Professional developers can extend these capabilities to address advanced business requirements.

Key developer extensibility points

Custom web page templates built with HTML, CSS, and Liquid

Extend site integration with Dataverse with the portals Web API

Use Visual Studio Code and the Power Platform CLI to enable metadata editing and CI/CD (Continuous Integration/Continuous Deployment) of site configurations

Dataverse

Dataverse is a cloud scale data store that builds on Microsoft's data technologies and abstracts away data management complexity from the app maker. It lets you securely store and manage data that is used by business applications. Business data within Dataverse is stored within a set of data tables. Role-based security allows businesses to control access to the data tables and even individual records for different users within your organization. Developers can extend or customize Dataverse functionality by adding custom business logic. You can define calculated table columns, business rules, workflows, and business process flows to ensure data quality and drive business processes.

Key developer extensibility points

Create plug-ins, similar to event handlers, that customize or extend Dataverse data processing with custom business logic (code)

Use webhooks and Azure Service Bus to integrate with external systems

Extend the Dataverse API with your own custom API that implements your business logic

Use virtual tables to integrate data stored in external systems into Dataverse without replicating the data
