Scaling with Proxies
 |
Much of the load that Sonatype Nexus Repository must bear comes from reads rather than writes. Scaling with proxy nodes allows you to take read load off of a primary Sonatype Nexus Repository instance (node) by using proxy nodes with a load balancer to split read traffic.
The proxy nodes are identical to the primary node and don't need to share any state. However, if you make a repository on your primary node, you will need to make a corresponding proxy in the proxy layer.
Combines With
You could make your primary node a cluster and combine this pattern with one of the following patterns:
Ensure you have perfected the Backup/Same-Site Restore pattern before combining it with more advanced patterns like this one
Problems Addressed
Reduces read load on primary Sonatype Nexus Repository instance (node)
Prerequisites
Resilient network connectivity between the primary and proxy nodes
Common DNS name can ensure low-network latency
Factors to Consider
Must maintain corresponding repository structures between primary and proxy nodes
