Azure Arc is a crucial cloud computing solution provided by Microsoft for the efficient hybrid management of resources. Unlike traditional solutions, Azure Arc brings Azure services and management features to virtually any infrastructure, making it possible to manage resources irrespective of where they’re located. The infrastructure may be placed across multi-clouds, on-premises, or at the edge. It serves several primary purposes, including management of resources, data services everywhere, and application deployments.
Let us delve into these purposes:
Management Of Resources
Azure Arc facilitates management of your different resources, such as servers, SQL servers, and Kubernetes clusters, as if they were a part of Azure. Even if these assets exist outside of Azure – perhaps on other cloud platforms or in an on-premise data center – you can easily onboard them to Azure Arc for centralized management.
With Azure Arc, you can perform key monitoring and management tasks such as viewing your assets in a global context, organizing them by custom or hierarchical grouping, searching and indexing them, tagging them, and even using role-based access control on them.
Below is an example that demonstrates how Kubernetes cluster, running on-premises is represented in Azure portal after registering with Azure Arc.
POST /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Kubernetes/connectedClusters/{clusterName}/default
By managing resources from a centralized Azure location, companies save both the time and effort typically required to manage resources individually from separate platforms.
Data Services Everywhere
Azure Arc also allows users to get Azure data services everywhere, providing them with the freedom to innovate anywhere with Azure SQL Managed Instance and Azure PostgreSQL Hyperscale. Azure Arc Data services are like SQL managed instances and PostgreSQL Hyperscale, which extend native Azure tools, security, and management to any infrastructure.
Here, users can continue to use familiar tools and benefits like Azure Security Center, Azure Policy, and Azure Lighthouse, ensuring that the tools and systems they prefer are readily available rather than needing to master separate systems for different platforms.
Application Deployments
Azure Arc helps in the deployment of Azure applications anywhere. For example, it enables developers and administrators to deploy containerized applications to any Kubernetes cluster across datacenters, multi-cloud, and edge environments using GitOps-based configuration management.
Users can manage these deployments, monitor the applications’ health and troubleshoot issues across all the environments from Azure portal. This ensures that their business applications can take advantage of Azure cloud scalability, rapid deployment, and development tools, regardless of the underlying infrastructure.
Azure Arc is a powerful tool that extends the Azure management plane and data/services plane beyond Azure. Whether your infrastructure is located on-premises, in multi-clouds, or at the edges, Azure Arc allows standardized visibility, operations, and compliance to be achieved through consistent and unified management. This tool is not only innovative, but it also disrupts norms and breaks traditional barriers in hybrid cloud computing.
Here is a comparison of Azure Arc vs traditional management methods:
| Feature | Azure Arc | Traditional management methods |
|---|---|---|
| Resource Management | Centralized | Spread across different platforms |
| Data Services | Across Infrastructures | Confined to single infrastructure |
| Application Deployments | Available Everywhere | Confined to a single environment |
In essence, the use of Azure Arc enhances flexibility and productivity while simplifying IT operations, thus increasing cost efficiency.
