Multi-node deployments

Multi-node hardware requirements

Based on our performance tests, we recommend the maximum numbers below:

• 150,000 attended robots connected to Orchestrator and running jobs
• 10,000 Action Center users processing actions
• 3,000 unattended robots running jobs (creating actions and resuming after the actions completion)

Environment Configuration

To ensure seamless performance for the above scenario, we recommend setting the environment below.

Instance	No. of Deployment Nodes	Azure VM	vCPU Cores	Frequency (GHz)	RAM (GB)
Action Center	3	B2s	2	2.0	4
Orchestrator	10	F16	16	2.0	32
SQL Server	1	F32	32	2.0	64

Drive Storage

Allocate a drive for each of the following content:

Stored Content	Drive Capacity
Database	1TB
Temporary database	1TB
Transactional logs	1TB

Database Setup

Product	Configuration
Redis Enterprise HA	CentOS 8 CPU Cores 2.0 GHz minimum frequency 16GB RAM
Bucket storage VM	Standard L32s_v2 Ultra Disc 4TB 900MB/s throughput

Test Setup and Sample Data

We generated the hardware requirements, along with additional setups and configurations, by conducting performance tests that simulate a large load on Action Center and Orchestrator. The tests were performed using the following sample data:

• 10,000 concurrent Action Center users
• 240,000 actions
  • 60% document validation actions
  • 40% form actions
• Payload per one form action:
  • Form layout—5KB
  • Form data—5KB
  • 10 storage files x 100KB
• Payload per one document validation action:
  • One PDF file x 150KB
