Understanding Servers in IT Infrastructure 🌐
Role of Servers 🖥️
Purpose: Servers provide essential IT services such as email, file storage, and website hosting. These services are crucial for employee productivity and organizational operations.
Definition: A server is a machine or software that delivers services to other machines or software. For instance:
Web Server: Stores and serves web content to clients over the internet (e.g., google.com).
Email Server: Manages and delivers email services.
SSH Server: Provides secure shell access for remote management.
Clients and Servers 🤝
Clients: Devices or applications that request and use services from servers.
Interaction: Servers can provide services to multiple clients simultaneously, and clients can utilize services from multiple servers.
Server Hardware and Types 🏢
Standard Hardware: Industry-standard servers operate 24/7 and use robust hardware, unlike personal laptops.
Tower Servers: Upright units that can be placed on a desk or in a closet.
Rack Servers: Flat units mounted in a 19-inch rack, suitable for larger setups.
Blade Servers: Slimmer servers designed for high-density environments.
Customization and Connection 🔌
Customization: Server hardware can be tailored to specific needs, such as increased storage for file servers.
Remote Management: Administrators can manage servers remotely using tools like SSH. For physical access:
KVM Switch: A device allowing control of multiple servers from a single keyboard, monitor, and mouse setup, useful for managing several servers efficiently.
