Nexus Repository Reference Architecture 4
Tip
Do you fit this profile?
This reference architecture describes deployment strategies and system requirements for a single Nexus Repository deployment not exceeding the following specifications:
500 max licensed contributing developers who are part of the software development lifecycle
500,000 max requests per day
500 repositories max
50TB max blob storage
If you don’t fit this profile, please see the reference architecture main page to find the deployment profile that best matches your needs.
Very large enterprise-grade deployments require multiple Sonatype Nexus Repository Pro instances in a high-availability (HA) environment to appropriately handle demand.
There are two tested architectures to consider:
High Availability (HA) Nexus Repository Pro deployment
Read Proxies/Replication
High Availability Nexus Repository Pro Deployment
Sonatype Nexus Repository HA deployments can be accomplished using any of our HA deployment options.
