Microsoft Azure

What Azure is

Microsoft Azure is a general cloud platform for IT and enterprise teams, with compute, storage, databases, networking, analytics, AI and integration services under one roof. Its documentation hub for China, run for Azure operated by 21Vianet, describes the goal as learning how to build and manage powerful applications on Azure, with documentation, sample code and tutorials. The listing is filed under workflow automation because of one service in particular: Logic Apps, described in the Chinese-language docs as "在云中自动访问和使用数据，而无需编写代码", meaning it automates access to and use of data in the cloud without writing code.

Azure as a whole is not a single no-code builder. It is a large catalog where a few services let non-developers assemble integrations and automations, and many others are for engineers. The reader this fits is an IT or enterprise team choosing a governed platform for many builders and workloads, not a founder looking for a one-evening app. The docs organize the catalog into groups: AI and machine learning, DevOps, web, analytics, media, storage, security, containers, developer tools, databases, identity, hybrid and multicloud, IoT, mobile, management and governance, networking, virtual desktop, compute, migration and integration.

What you build and how

The docs group the integration services together under one heading: API Management, Azure Web PubSub, Logic Apps, Event Grid and Service Bus. Each does a different job.

• Logic Apps is the workflow service, built to automate cloud data access without code.
• Event Grid is described as "实现大规模可靠的事件传递", reliable event delivery at massive scale.
• Service Bus connects across private and public cloud environments.
• API Management publishes APIs to developers, partners and employees securely and at scale.
• Azure Web PubSub builds real-time messaging web apps using WebSockets and the publish-subscribe pattern.
• Event Hubs receives telemetry from millions of devices.
• Azure Functions processes events with serverless code, the code option in the same catalog.

A second automation service sits under management: Automation, described as simplifying cloud management with process automation. Where Logic Apps moves business data between systems, Automation is aimed at the operations work of running the cloud itself.

For data movement, the catalog lists Azure Data Factory as "企业级混合数据集成", enterprise-grade hybrid data integration. The English Data Factory page describes mapping data flows, which are available in both Azure Data Factory pipelines and Azure Synapse Analytics pipelines. Within them, the flowlet transformation runs a previously created flowlet. You pick the flowlet, then map columns from the incoming stream onto the flowlet's expected input columns. That mapping is what makes flowlets reusable snippets of mapping data flow logic across many data flows: a cleansing or lookup step built once can be dropped into every pipeline that needs it. The page shows the data flow script syntax with a short example, and states that the flowlet transformation is currently in public preview. Stream Analytics adds real-time analysis of fast-moving data streams from applications and devices.

Beyond workflows, the same catalog covers most things a team builds on a cloud. App Service creates web and mobile cloud apps quickly, and Web App for Containers deploys containerized web apps that scale with the business. Azure Container Apps builds and deploys modern apps and microservices with serverless containers, and Azure Container Instances runs containers without managing servers. Azure Kubernetes Service simplifies deploying and operating Kubernetes. Azure Spring Apps is a fully managed Spring Cloud service. Databases include Azure Cosmos DB, described as a fast NoSQL database with open APIs at any scale, Azure Cache for Redis, Azure SQL, and managed Azure Database for MySQL, PostgreSQL and MariaDB. For collaborative apps there are Azure Fluid Relay, which adds real-time collaboration through the Fluid Framework, Azure SignalR Service for real-time web features, and Notification Hubs for push notifications to any platform. IoT Hub is described as connecting, monitoring and managing billions of IoT assets.

The AI list is long: Azure AI services, AI Bot Service (a serverless bot service that scales on demand), AI Document Intelligence (an AI-driven extraction service that understands your forms), AI Search, AI Language, AI Content Safety, Azure Machine Learning, Translator, Speech and Vision. Translator, for example, performs machine translation through a simple REST API call. On the analytics side the docs list Azure Databricks, Azure Analysis Services, Azure Synapse Analytics, Azure Managed Grafana and Power BI Embedded, which embeds fully interactive data visualizations in an application.

For people who write code, the docs list Python, .NET, JavaScript, Java, Go, the REST API, Azure PowerShell and the Azure CLI, with ARM templates and Bicep for infrastructure as code, plus Jenkins and Terraform. Visual Studio and Visual Studio Code are the editors named, and the Azure portal is described as a single unified console to build, manage and monitor all Azure products. A Commercial Marketplace is described as an online marketplace of applications and services from independent software vendor partners.

Governance and security sit in the same catalog. Microsoft Entra ID is the identity service, which the docs say syncs on-premises directories and enables single sign-on, and Microsoft Entra External ID handles customer identity and access management in the cloud. Azure Policy enforces corporate governance and standards on Azure resources at scale, and Azure Blueprints (in preview) supports fast, repeatable creation of governed environments. Azure Monitor gives observability across applications, infrastructure and networks. Microsoft Defender for Cloud covers security posture and threat protection across Azure, hybrid and multicloud workloads, and Microsoft Sentinel is a cloud-native SIEM. Key Vault protects keys and other secrets, Microsoft Purview handles unified data governance, Azure Backup is described as simplifying data protection and guarding against ransomware, Azure Site Recovery keeps the business running with built-in disaster recovery, Azure Lighthouse lets service providers manage customers at scale, and Cost Management and Billing is for optimizing cloud spending.

What the documentation states

The documentation lists services and their purpose rather than prices; cost is covered by Cost Management and Billing, described as a way to optimize your cloud spending while getting the most from the cloud. A few other concrete facts:

• The China cloud is "由世纪互联运营的 Azure", Azure operated by 21Vianet, which the hub describes as a dedicated cloud located in China.
• The Data Factory page says the flowlet transformation is in public preview, so it is not a generally available feature.
• Azure Stack Hub is sold as integrated hardware systems with software pre-installed on validated hardware, and Azure Stack is described as a way to build and run hybrid applications across cloud boundaries.
• Azure Arc brings Azure services and management to any infrastructure.
• The hub points to Microsoft Learn for building Azure skills, an architecture center for designing apps, and a cloud adoption framework for organizational goals.

The documentation hub is available in Chinese and the Data Factory article in English, with light, dark and high contrast themes.

Who it suits and who it does not

Azure suits an enterprise or IT team that already needs cloud infrastructure and wants workflow and integration services next to its databases, identity and monitoring. A team in the Microsoft ecosystem can combine Logic Apps for connecting systems, Event Grid and Service Bus for messaging, Data Factory for data pipelines, and Functions for the steps that need code. Governance tools like Policy, Entra ID and Monitor make it a fit for organizations where many builders share one tenant.

It is a harder fit for a founder or a small team that wants a visual builder with templates and a single bill. The catalog is broad, so choosing the right service takes knowledge of the platform. Logic Apps removes code from integrations, but much of what surrounds it, such as Functions, containers and infrastructure templates, is aimed at developers. The Chinese documentation hub covers the China-operated cloud, so a team outside China should check which Azure cloud it will use.
