Factors to Consider
HA is an advanced feature that requires careful consideration. Consider the following points before deploying to an HA environment:
Containerized and cloud HA deployments require using several advanced technologies (e.g., Kubernetes, cloud technologies) outside the Sonatype Suite's scope. You should ensure that you have in-house expertise in these technologies before attempting an HA deployment.
HA requires additional infrastructure and maintenance overhead (See our Sonatype Nexus Repository High Availability Performance Data (AWS, Azure). Deploying HA without a strong need or use case may not yield your desired return on investment.
Sonatype Nexus Repository High Availability deployments should be fully deployed and tested in a development environment before attempting to deploy in production. Improper deployment in a production environment can result in critical data loss.
