System Requirements
To install and use nevisAdmin 4, respect the following system requirements:
- nevisAdmin 4 runs on
- nevisAppliance (admin4 image),
- Docker / Kubernetes, or
- RHEL 8/9 server.
- nevisAdmin 4 requires between 4 GB and 16 GB of RAM and between 2 and 6 CPU cores.
- The amount of RAM and cores required for your setup primarily depends on the following factors:
- Project size: Amount of patterns in the project and total project size in MB, including attachments.
- Number of projects that are edited/updated concurrently.
- Number of deployments that are executed concurrently.
- Number of target systems and instances that are deployed during one deployment.
- Vertical scaling is supported: You can increase RAM and CPU cores as needed.
- The Java Virtual Machine (JVM) can pose limitations to the vertical scaling: Adding more RAM or cores does not always increase the performance of Java applications.
- These numbers apply to production setups. For testing or development, performance may also be acceptable with less RAM or cores.
- The amount of RAM and cores required for your setup primarily depends on the following factors:
- The managed target systems (deployment hosts) must run on RHEL 7/8, nevisAppliance or on Kubernetes.
- For supported Kubernetes platforms and versions, see Example Installation on Azure.
- MariaDB 10.3.x is the minimum required version, but MariaDB 10.6.x or PostgreSQL 15 is the recommended.
- You can connect only one nevisAdmin 4 instance (server process) to the same database. Horizontal scaling is not supported on the same database.
- For version control of configuration projects, nevisAdmin 4 relies on a remote Git repository.
- nevisAdmin 4 has been tested to work together with Atlassian Bitbucket, GitLab, GitHub, and Gitea.
- nevisAdmin 4 requires a recent Java 17 version.
- nevisAdmin 4 always runs as nvbuser.
