Azure: What Is Microsoft Azure?
Définition
Microsoft Azure is Microsoft's cloud computing platform, the second-largest player in the global market. It offers over 200 cloud services covering compute, storage, AI, analytics, and development, with native integration into the Microsoft ecosystem (Office 365, Active Directory, Teams).What is Microsoft Azure?
Microsoft Azure, launched in 2010 as Windows Azure and renamed in 2014, is Microsoft's cloud platform. The second-largest global cloud service provider behind AWS with approximately 24% market share, Azure offers over 200 services covering all computing needs: compute, storage, databases, artificial intelligence, Internet of Things, DevOps, and much more. The platform operates in over 60 geographic regions, making it the cloud provider with the broadest global coverage.
Azure's major strength lies in its native integration with the Microsoft ecosystem. Companies already using Microsoft 365, Active Directory, Teams, or Dynamics 365 find in Azure a natural extension of their existing tools. Azure Active Directory (Entra ID) unifies identity management between cloud applications and on-premise environments, significantly simplifying IT administration.
At KERN-IT, we take a cloud-agnostic approach. We recommend Azure when the client context justifies it, particularly when the company is already heavily invested in the Microsoft ecosystem. Our Django and Python expertise integrates seamlessly with Azure services: Azure App Service for hosting, Azure Database for PostgreSQL for databases, and Azure Blob Storage for file storage.
Why Azure Matters
Azure holds a strategic position in the cloud computing market, driven by the power of the Microsoft ecosystem and sustained year-over-year growth.
- Native Microsoft integration: for companies using Microsoft 365, Teams, and Active Directory, Azure offers seamless integration. Single sign-on (SSO), identity management, and security policies are unified, reducing operational complexity.
- Leading hybrid cloud: Azure Arc and Azure Stack allow extending Azure services to on-premise and multi-cloud environments. This hybrid approach is particularly relevant for companies that cannot fully migrate to the cloud for regulatory or technical reasons.
- European compliance: with regions in France (Paris, Marseille), the Netherlands, Germany, and Belgium (recently launched Belgium Central region), Azure meets GDPR and data sovereignty requirements for European businesses.
- AI and cognitive services: Azure OpenAI Service provides access to GPT models directly within the Azure environment, with Microsoft's security and compliance guarantees. Azure Cognitive Services offer ready-to-use APIs for vision, language, and speech.
- Enterprise support: Microsoft enterprise contracts often include Azure credits, and Microsoft sales teams provide direct support. For large enterprises, this premium support is a decisive argument.
How It Works
Azure operates on the same on-demand cloud model as its competitors: resources are provisioned through the Azure web portal, the command-line interface (Azure CLI), SDKs (including the Python azure-sdk), or Infrastructure as Code tools like Terraform and Bicep (Azure's native declarative language).
Resources are organised into Resource Groups, which simplify management, billing, and access control. Each resource is deployed in a specific region and can be replicated to other regions for redundancy. The Subscriptions system allows separating environments (development, staging, production) with distinct budgets and security policies.
Security relies on Azure Active Directory (Entra ID) for identity management, Role-Based Access Control (RBAC) for granular permissions, and Azure Key Vault for secure storage of secrets and certificates. Azure Policy enables defining and enforcing governance rules across the organisation.
Concrete Example
Consider a company that already uses Microsoft 365 and Active Directory for employee management, and wants to deploy a Django application. By choosing Azure App Service, it is possible to integrate application authentication directly with Azure AD, allowing employees to log in with their existing Microsoft credentials via SSO.
The PostgreSQL database can be hosted on Azure Database for PostgreSQL with geographic replication and automatic backups. Sensitive documents are stored on Azure Blob Storage with server-side encryption. Azure CDN distributes static assets (CSS, JavaScript, images) for an optimal user experience. Everything is monitored via Azure Monitor with alerts configured for critical performance thresholds.
Implementation
- Create an Azure account: sign up at portal.azure.com. Azure offers $200 in free credits for 30 days and a permanent free tier for many services.
- Structure the organisation: define a hierarchy of Management Groups, Subscriptions, and Resource Groups suited to your organisation. Separate dev/staging/prod environments in distinct subscriptions.
- Configure identity: if your company uses Active Directory, configure synchronisation with Azure AD. Enable multi-factor authentication (MFA) for all users and configure RBAC.
- Deploy the application: for a Django application, use Azure App Service (PaaS) or Azure Container Instances. Configure continuous deployment from your Git repository.
- Provision supporting services: add Azure Database for PostgreSQL, Azure Blob Storage, and Azure CDN as needed. Use Terraform or Bicep to automate provisioning.
- Monitor and optimise: enable Azure Monitor and Application Insights for performance tracking. Use Azure Advisor for cost and security optimisation recommendations.
Associated Technologies and Tools
- Azure App Service: PaaS hosting for web applications, ideal for Django and Python projects.
- Azure Database for PostgreSQL: fully managed PostgreSQL database with high availability.
- Azure Blob Storage: scalable object storage for files and media.
- Azure CDN: global content delivery network for static assets.
- Azure Active Directory (Entra ID): cloud identity and access management.
- Azure DevOps: integrated CI/CD suite with pipelines, Git repos, and project management.
Conclusion
Microsoft Azure is a mature and comprehensive cloud platform, particularly relevant for companies already embedded in the Microsoft ecosystem. Its native integration with Active Directory, Office 365, and Microsoft productivity tools makes it a natural choice for many organisations. PaaS services like Azure App Service and Azure Database for PostgreSQL significantly simplify Django application deployment. At KERN-IT, we recommend Azure when the client context justifies it, combining our Python/Django expertise with Azure managed services for reliable and secure deployments.
If your company already uses Microsoft 365, check for Azure credits included in your Enterprise Agreement. Many companies have unused Azure credits they are unaware of. Combine this with Azure Reserved Instances for predictable workloads and you can reduce your cloud costs by 30-50%.
