CRM System
- CRM System Server Configuration
This document details the server configuration for the Customer Relationship Management (CRM) system, providing guidance for new system administrators and engineers. It covers hardware specifications, software requirements, network considerations, and security best practices. This guide assumes a base installation of a Linux-based operating system (specifically, Ubuntu Server 22.04 LTS is recommended). Familiarity with System Administration and Linux command line is expected.
== 1. Overview
The CRM system is a critical component of our business operations, managing customer data, sales processes, and marketing campaigns. A robust and reliable server infrastructure is essential for its performance and availability. This configuration aims to balance performance, scalability, and security. We use a three-tier architecture: a web server tier, an application server tier, and a database server tier. Each tier is described below. See also Database Management for more information.
== 2. Hardware Specifications
The following tables detail the hardware requirements for each server tier. These are minimum recommended specifications; scaling may be necessary based on usage patterns. The chosen servers are physically located in the dedicated server room, adhering to Data Center Standards.
=== 2.1 Web Server Tier
This tier handles incoming HTTP/HTTPS requests and serves static content.
| Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon Silver 4310 (or AMD EPYC 7313) | 2 |
| RAM | 32 GB DDR4 ECC | 2 |
| Storage | 2 x 480 GB SSD (RAID 1) for OS and static content | 2 |
| Network Interface | 1 Gbps Ethernet | 2 |
| Power Supply | Redundant 750W PSU | 2 |
=== 2.2 Application Server Tier
This tier executes the CRM application logic. Multiple application servers may be deployed for load balancing and high availability. See also Load Balancing Techniques.
| Component | Specification | Quantity | CPU | Intel Xeon Gold 6338 (or AMD EPYC 7543) | 4 |
|---|---|---|---|---|---|
| RAM | 64 GB DDR4 ECC | 4 | |||
| Storage | 2 x 960 GB SSD (RAID 1) for application code and temporary files | 4 | |||
| Network Interface | 10 Gbps Ethernet | 4 | |||
| Power Supply | Redundant 850W PSU | 4 |
=== 2.3 Database Server Tier
This tier stores and manages the CRM data. This is the most critical component and requires the most robust hardware. Refer to Database Security for further details.
| Component | Specification | Quantity |
|---|---|---|
| CPU | Intel Xeon Platinum 8380 (or AMD EPYC 7763) | 2 |
| RAM | 128 GB DDR4 ECC | 2 |
| Storage | 8 x 4 TB SAS HDD (RAID 10) for data storage | 2 |
| Network Interface | 10 Gbps Ethernet | 2 |
| Power Supply | Redundant 1200W PSU | 2 |
== 3. Software Configuration
The following software components are required for the CRM system.
- **Operating System:** Ubuntu Server 22.04 LTS
- **Web Server:** Apache 2.4 (configured with mod_ssl for HTTPS) - See Apache Configuration
- **Application Server:** Java 17 (OpenJDK recommended) with a compatible application server like Tomcat 9 or Jetty 11.
- **Database Server:** PostgreSQL 14 (with appropriate extensions for CRM functionality) - See PostgreSQL Administration
- **Caching:** Redis 6.x (for session management and data caching)
- **Monitoring:** Prometheus and Grafana for system monitoring and alerting - consult System Monitoring
- **Firewall:** UFW (Uncomplicated Firewall)
== 4. Network Configuration
- **IP Addressing:** Static IP addresses are assigned to each server.
- **DNS:** Proper DNS records are configured to resolve the CRM system's hostname.
- **Firewall Rules:** UFW is configured to allow only necessary traffic (HTTP, HTTPS, SSH, PostgreSQL). See Firewall Management.
- **Load Balancer:** An HAProxy instance is used to distribute traffic across the application servers.
- **VPN:** A secure VPN connection is established for remote administration.
== 5. Security Considerations
- **SSL/TLS:** All communication is encrypted using SSL/TLS certificates.
- **Firewall:** A robust firewall configuration is implemented.
- **User Authentication:** Strong password policies and multi-factor authentication are enforced. See User Account Management.
- **Regular Security Audits:** Regular security audits are conducted to identify and address vulnerabilities.
- **Data Backups:** Daily full backups and incremental backups are performed, stored offsite. Refer to Backup and Recovery Procedures.
- **Intrusion Detection System (IDS):** An IDS is implemented to detect and respond to malicious activity.
== 6. Future Scalability
The system is designed for scalability. Additional application servers can be added behind the load balancer to handle increased traffic. Database scaling can be achieved through replication and sharding (although this is a more complex undertaking). Regular capacity planning is crucial. See also Capacity Planning.
