System requirements for PowerShell Universal
Hardware
Hardware recommendations are based on use and depend on how many scripts are running on the PowerShell Universal server and how many users are accessing the machine. Unix based machines typically require less hardware requirements than Windows based machines. The below recommendations are based on low use of the system.
Minimum
This is the base line for a Universal server with very minimal server load. It should be used for trial or development purposes only.
2 CPU
4 GB
250 GB
SQLite Database
Recommended
This is the base line for a Universal server running several jobs an hour, hosting APIs with fewer than 100 requests per hour and a single App. It will support up to 10 concurrent users.
4 CPU
16 GB
500 GB
MS SQL\PostgreSQL Database
Performance
This is the base line for a Universal server running dozens of jobs an hour, hosting APIs with greater than 100 requests per hour and up to 5 Apps. It will support up to 50 concurrent users.
16 CPU
32 GB
1 TB
MS SQL\PostgreSQL Database
Distributed
A distributed system employs multiple instances of PowerShell Universal connected to the same database. It requires either Git or managed deployments to share configuration data. We recommend this for widely used production instances. It provides the best performance, stability and redundancy.
This configuration can support hundreds of jobs per hour, thousands of API requests and many apps. The number of concurrent users will depend on the number of PSU servers in the cluster.
