Looking at the Power Platform from the outside, you see services like Power Apps, Power Automate, Power BI, Power Pages, Copilot Studio, and Microsoft Dataverse. Looking at it from the inside, you see a single platform built on shared foundations. That’s what makes building solutions on the Power Platform feel unified rather than like stitching separate tools together.

How Do the Services Work Together?

Every Power Platform service is designed to integrate with the others. Behind the scenes, they share common foundations such as Microsoft Entra ID, environments, connectors, Microsoft Dataverse, governance tools, and increasingly, Copilot capabilities. This allows apps, flows, pages, dashboards, and agents to work together as part of a unified business solution.

Each service can work independently, but the platform delivers the most value when services are combined. A typical solution might connect a Power App to a Power Automate flow, use Dataverse as a shared data source, embed Power BI reports into an app, or connect a Copilot Studio agent to automated workflows.

Key Concepts

Dataverse — The Shared Data Layer

Most multi-service solutions use Microsoft Dataverse as a central data store. A canvas Power App, a Power Automate cloud flow, a Power Pages site, and a Copilot Studio agent can all read from and write to the same Dataverse tables, with consistent row, column, and table-level security applied across the platform.

Connectors — The Universal Bridge

The connector library is shared across Power Platform services. Connectors such as SharePoint, Outlook, and Salesforce can be used in apps, flows, pages, and agents. Data Loss Prevention (DLP) policies are also applied consistently across these services to help control data movement.

Power Fx — The Shared Logic Language

Microsoft Power Fx is an Excel-like low-code language used to define logic across the platform. It is primarily used in canvas Power Apps and Dataverse formula columns, with expanding support in Copilot Studio and other Power Platform experiences. The syntax is consistent, even when used in different surfaces.

Copilot — The Shared AI Layer

Copilot capabilities are integrated across Power Platform services. A generative AI assistant helps users build apps, design flows, create pages, configure Dataverse, and author agents using natural language.

Single Tenant, Shared Governance

All Power Platform services use Microsoft Entra ID for identity, environments for isolation, and the Power Platform admin center for governance. This ensures consistent security, Data Loss Prevention (DLP) policies, and administrative control across the platform.

The Business Value

• One platform, shared foundation — Power Platform services share core components such as environments, identity, connectors, and governance, along with aligned roadmaps.
• Reusable building blocks — Data (via Microsoft Dataverse), logic, and connectors can be reused across apps, flows, pages, and agents.
• Low-code integration — Services are designed to work together with minimal custom code; many integrations can be achieved through configuration rather than traditional development.
• Solutions packaging — Apps, flows, tables, and pages can be packaged together using solutions and deployed as a single unit across environments.
• Consistent governance — Centralized administration through the Power Platform admin center enables consistent security, Data Loss Prevention (DLP) policies, and environment-based control across services.
• Faster delivery — Most business solutions combine multiple services; shared components reduce duplication and speed up solution delivery.

Common Patterns and Use Cases

Scenario	Services Working Together
Employee leave-request app	Power Apps (form) + Power Automate (approval workflow) + Microsoft Dataverse (data storage)
Customer self-service portal	Microsoft Power Pages + Microsoft Dataverse (data) + Copilot Studio (chat support)
Invoice processing pipeline	Power Automate (document capture and flow) + AI Builder (document processing) + Microsoft Dataverse (store data)
Departmental Teams app	Power Apps + Dataverse for Teams + Power Automate (notifications)
AI-powered helpdesk	Copilot Studio (agent) + Power Automate (actions/workflows) + Microsoft SharePoint (knowledge base)

Quick Reference

Feature	What to Know
Shared data layer	Microsoft Dataverse is a primary data platform used across Power Platform services.
Shared connectors	A common connector library is available across apps, flows, pages, and agents.
Shared logic	Microsoft Power Fx is used across multiple services for defining logic.
Shared AI	Copilot capabilities are integrated across Power Platform services to assist with building and managing solutions.
Shared identity	Microsoft Entra ID (formerly Azure Active Directory) provides identity and access management for all services.
Shared governance	The Power Platform admin center, environments, and Data Loss Prevention (DLP) policies provide centralized governance.
Solutions	Solutions are used to package and deploy apps, flows, tables, and pages together across environments.
Common patterns	App + flow, page + Dataverse, agent + flow, app + agent are common solution patterns.
