Container architecture design

Containers have become the standard for packaging and deploying modern applications. Azure provides a comprehensive set of container services that range from fully managed Kubernetes clusters to serverless container platforms. Whether you're modernizing existing applications, building cloud-native microservices, or running stateful workloads, Azure container services offer the flexibility, portability, and scalability your organization needs.

Choosing the right container platform depends on your workload requirements, operational expertise, and business goals. Key considerations include orchestration complexity, scaling requirements, networking needs, and the level of control you want over the underlying infrastructure. Azure's container portfolio spans infrastructure as a service (IaaS), platform as a service (PaaS), and serverless models, allowing you to select the approach that best fits your architecture.

Organizational readiness

To help assure the quality of your container solution on Azure, we recommend following the Azure Well-Architected Framework (WAF). WAF provides prescriptive guidance for organizations seeking architectural excellence and discusses how to design, provision, and monitor cost-optimized Azure solutions.

For container-specific guidance, see the Azure Well-Architected Framework service guides for:

• Azure Container Apps
• Azure Kubernetes Service

Operations guide

Getting your workload deployed on Azure is a great milestone, and this is when day-2 operations become critical.

AKS operations

The AKS day-2 operations guide helps ensure you're ready to meet operational demands for Kubernetes workloads.

AKS day-2 operations guide

Key AKS operational areas:

• Triage practices - Systematic approach to troubleshooting AKS issues.
• Backup and recovery for AKS - Protect your cluster configuration and workloads.
• Patch and upgrade worker nodes - Keep clusters secure and up to date.
• Troubleshoot networking - Diagnose and resolve network issues.
• Monitor AKS with Azure Monitor - Collect and analyze telemetry from your clusters.

Container Apps operations

Azure Container Apps reduces operational overhead with managed infrastructure, but you still need to monitor and manage your applications:

• Monitor Container Apps - Use Azure Monitor, Log Analytics, and Application Insights for observability.
• Health probes - Configure liveness, readiness, and startup probes for container health.
• Revisions and traffic splitting - Manage application versions and implement blue-green deployments.
• Quotas and limits - Understand service limits and plan capacity accordingly.

Best practices

Following best practices helps ensure your container solution on Azure is reliable, secure, and cost-effective.
