Description

Connected registry in Azure Container Registry (ACR) is now generally available. Connected registry is a local resource managed using a cloud-based ACR registry. It can be deployed via the Azure Portal and Command Line Interface (CLI) as an Arc extension on Arc-enabled Kubernetes clusters, or in an environment that supports container workloads on premises/remote. Connected registry synchronizes images and other OCI artifacts between the ACR registry and the on-prem connected registry. Integrating with Azure Arc simplifies governance and management by delivering a consistent multi-cloud and on-premises management solution. 


Key Benefits: 

  1. Efficiency: fast on-premises access to containerized workload enhances operational efficiency by mitigating latency and improving performance.  
  2. Security: provides greater control over data security and compliance, as all operations are managed within the organization’s own infrastructure. 
  3. Flexibility: can be configured to synchronize a subset of the repositories from the ACR registry or to synchronize only during certain intervals to reduce traffic between the cloud and the on-premises. 
  4. Scalability: supports scaling of deployments to ensure services are delivered with minimal delay for both occasional and always connected customer scenarios. 
  5. Garbage Collection: reclaims storage space by removing objects that are no longer being used.
