What is azure arc

Overview

Azure Arc is a Microsoft service designed to extend Azure's management capabilities beyond the cloud to encompass on-premises infrastructure, multiple cloud providers, and edge computing environments. It provides a unified management plane allowing IT administrators to govern, secure, and monitor resources wherever they operate, whether in AWS, GCP, or on physical hardware.

Core Capabilities

Azure Arc offers several key functionalities for hybrid and multi-cloud environments:

• Unified Management: Manage servers, Kubernetes clusters, and databases across hybrid and multi-cloud environments from the Azure portal.
• Policy Enforcement: Apply consistent policies, security standards, and compliance requirements across all infrastructure using Azure Policy.
• Update Management: Deploy patches and updates consistently across on-premises and cloud resources automatically.
• Monitoring and Logging: Collect logs and metrics from all resources for centralized analysis, alerting, and performance optimization.
• GitOps Configuration: Implement GitOps workflows for managing configurations across hybrid environments with version control and automated deployments.

Supported Environments

Azure Arc extends management to diverse infrastructure scenarios. It supports Windows and Linux servers running on any hypervisor or physical hardware, Kubernetes clusters from any vendor including EKS and GKE, edge devices running Azure Stack Edge, and databases including SQL Managed Instance and PostgreSQL Hyperscale. This broad support enables organizations with complex infrastructure to simplify management.

Data Services and Applications

Azure Arc enables organizations to run Azure data services on their own infrastructure. SQL Managed Instance and PostgreSQL Hyperscale databases can operate on-premises while providing benefits like automatic updates, scaling, and billing through Azure. Additionally, organizations can deploy Azure applications and services consistently across all environments, ensuring uniform experiences regardless of location.

Security and Compliance

The service enforces security standards and compliance requirements uniformly across all infrastructure. Azure Arc integrates with Azure Security Center to provide threat detection, vulnerability assessments, and security recommendations. Organizations can ensure consistent security postures regardless of where resources operate, reducing risk in hybrid and multi-cloud environments significantly.
