Definition of a Server
A server is a powerful computer or software system that provides services and resources to other devices (clients) within a network. In an small and mid-sized business, are servers used for data storage, running business applications, managing users, or acting as a central communication hub. Servers can be located on-premise (in the office) or hosted in the cloud.
Examples of Most Common Servers in Small and Mid-Sized Business
- File Server – Stores and shares company documents and backups (e.g., NAS devices).
- Mail Server – Manages company emails (e.g., Microsoft Exchange, Zimbra, or cloud services like Google Workspace).
- Application Server – Runs business applications like accounting software, CRM, or ERP (e.g., QuickBooks, SAP, or Zoho).
- Database Server – Handles databases for business systems (e.g., Microsoft SQL Server, MySQL, PostgreSQL).
- Web Server – Hosts the company website or internal systems (e.g., Apache, Nginx, IIS).
- Virtualization Server – Runs multiple virtual machines for different purposes (e.g., VMware ESXi, Proxmox, Microsoft Hyper-V).

- On-Premise Server – Physically located in the office, requiring regular maintenance, backups, and security management. Provides more control over data.
- Cloud Server – Hosted by a provider (e.g., AWS, Microsoft Azure, Google Cloud), reducing hardware concerns and allowing easy scalability.
- Hybrid Solution – A mix of on-premise and cloud services for optimized costs and security.
