Topology Planning

Based on existing production deployments, we have determined a suggested number of servers based on total entitlement assignments. These suggested number of servers are guidelines for your particular deployment requirements. Unique client requirements may require customization, which may differ from the listed number of servers.

For a description of possible production deployments, see Deployment Architecture in the Autonomous Identity Installation Guide.

Suggested Number of Servers

Data Set Ranges
	Small	Medium	Large	Custom
Total Assignments	<1M	1-5M	5-15M	15M+
Suggested # of Servers
Application	Discuss with Autonomous Identity Team (dependent on HA requirements)[1]
Database	2	2	3	Custom[2]
Analytics	1	2	3	Custom[2]
Deployer[3]	1	1	1	1

[1] Docker Swarm is designed to be highly available and may require 5 or more nodes. For a production deployment, the specific requirements can be discussed with the Autonomous Identity Team. Docker Swarm requirements are not correlated to data set size, but to front-end user requirements (for example, the number of users and frequency of use).
[2] For environments with more than 15 million assignments, server requirements will need to be specifically customized.

Production Technical Specifications

Autonomous Identity 2021.3.1 has the following technical specifications for production deployments:
