Sizing
This article describes the sizing requirements for your contact center based on the number of agents using Genesys.
Sizing recommendations for standard deployment
Standard hardware requirement is as follows:
- 4CPU cores, 16GB RAM, 32GB HDD for Standard GWS VM.
- One VM for API (no WWE) + Platform service – can handle 1000 concurrent agents, login rate 1 agent/sec, transactions not limited factor.
- For small non-production lab deployments with less than 10 concurrent agents, databases may be deployed on the same VM or host.
Sizing recommendations based on concurrent agents usage
The following table provides hardware sizing information for each Data Center based on the number of concurrent agents' usage.
| Contact Center Size | Hardware Sizing for HA | Service Description |
| Small (<=1000 concurrent agents) | 1+1 GWS VMs (or 1 single GWS VM for non-HA deployments) |
|
| Medium (<=5000 concurrent agents) | 1+1 GWS VMs |
|
| N+1 GWS VMs (1 VM per 1000 concurrent agents) |
| |
| Optional: 1 Load Balancer |
| |
| Large (>5000 concurrent agents) | 1+1 GWS VMs |
|
| 1+1 GWS VMs |
| |
| N+1 GWS VMs (1 VM per 1000 concurrent agents) |
| |
| K+1 GWS VMs |
| |
| 1 Load Balancer (determined by the customer) |
| |
| 1 Load Balancer |
| |
| Platform Service-only (typically for Outbound Contact Expert without Agent Desktop) | 1+1 GWS VMs |

Redis Sizing Guidelines
For production deployments of GWS 8.6, the requirements of 3 primary and 3 replica nodes for a Redis cluster should be sufficient.
The number of Redis keys is 6 keys per agent (1 key per agent session, 3 keys per current active session, 1 key per call, 1 key per agent's interactions), with key size up to 4kB
Index size: 50 MB per 10,000 agents
Throughput: Up to 12 operations/sec with Redis under high load for each agent session (depends on specific traffic profile for a deployment)
