Network	10 Mbps	100 Mbps

Scaling Guidelines

Agent Count	CPU	RAM	Storage
1-100	2 cores	2 GB	20 GB
100-500	4 cores	4 GB	50 GB
500-1000	4 cores	8 GB	100 GB
1000+	8 cores	16 GB	200 GB

Operating System

Supported:

• Ubuntu 22.04 LTS (recommended)
• Ubuntu 20.04 LTS
• Debian 11/12
• RHEL 8/9
• Rocky Linux 8/9

Software Dependencies

Docker Deployment:

• Docker 24.0+
• Docker Compose 2.20+

Manual Deployment:

• Python 3.11+
• PostgreSQL 14+
• Redis 7+
• Node.js 20+ (for building frontend)

Database Requirements

PostgreSQL

Version: 14 or higher

Configuration:

# postgresql.conf
max_connections = 100
shared_buffers = 256MB
effective_cache_size = 768MB
work_mem = 4MB

Redis

Version: 7 or higher

Configuration:

# redis.conf
maxmemory 256mb
maxmemory-policy allkeys-lru

Network Requirements

Ports

Port	Protocol	Purpose
443	TCP	HTTPS (Frontend + API)
80	TCP	HTTP → HTTPS redirect
8000	TCP	Backend API (internal)
5432	TCP	PostgreSQL (internal)
6379	TCP	Redis (internal)

Firewall Rules

Inbound (from Internet):

• 443/tcp - HTTPS access
• 80/tcp - HTTP redirect (optional)

Inbound (from Agents):

• 443/tcp - Agent WebSocket connections

SSL/TLS

A valid SSL certificate is required for production. Options:

1. Let's Encrypt (recommended) - Free, automated
2. Commercial CA - Purchased certificate
3. Self-signed - Development only

Agent Requirements

Windows

Resource	Minimum
OS	Windows 10/11, Server 2016+
Architecture	x64
RAM	50 MB
Disk	50 MB

Linux

Resource	Minimum
OS	Any modern distribution
Architecture	x64, ARM64
RAM	20 MB
Disk	20 MB

Supported Distributions:

• Debian / Ubuntu
• RHEL / CentOS / Fedora
• Arch Linux
• Alpine Linux

macOS

Resource	Minimum
OS	macOS 11+ (Big Sur)
Architecture	Intel (x64), Apple Silicon (ARM64)
RAM	30 MB
Disk	30 MB

Browser Requirements

The web dashboard supports:

• Chrome 90+
• Firefox 90+
• Safari 14+
• Edge 90+

JavaScript must be enabled.

Network Connectivity

Agents require:

• Outbound HTTPS (443) to the SlimRMM server
• Stable internet connection
• No proxy that terminates TLS (mTLS is used)

Proxy Considerations

If agents are behind a proxy, ensure the proxy:

• Supports WebSocket connections
• Does not terminate TLS (pass-through mode)
• Allows connections to your SlimRMM server
