Understand servers¶
If you're interested in learning more about how to utilize cloud computing resources, it's helpful to understand what servers are, their hardware specifications, protocols, and uses.
What is a server?¶
A server is a computer designed to provide services, data, or resources to other computers, known as clients, over a network. Unlike regular desktop computers, servers are built to handle multiple requests simultaneously, operate continuously, and manage large amounts of data.
Servers are the backbone of cloud computing, providing the computational power and resources needed to run applications and services.
Hardware specifications¶
Servers come in various configurations, but some key hardware specifications are common:
-
Processor (CPU): The central processing unit is the brain of the server, executing instructions and managing tasks. Servers often use multi-core processors or multiple processors to handle concurrent requests efficiently.
-
Memory (RAM): Random access memory is crucial for a server's performance, as it stores data that the CPU needs quick access to. Servers typically have a larger amount of RAM compared to desktop computers to manage multiple simultaneous connections.
-
Storage: Servers use hard disk drives (HDDs) or solid-state drives (SSDs) for storing data. SSDs are faster and more reliable but tend to be more expensive.
-
Network interface: Servers have network interface cards (NICs) to connect to the network, often with higher bandwidth capabilities to handle large amounts of data transfer.
Protocols¶
Servers communicate with clients and other servers using various protocols.
-
HTTP/HTTPS (Hypertext Transfer Protocol/Secure) is used for transferring web pages and data on the internet.
-
FTP (File Transfer Protocol): is used for transferring files between computers on a network.
-
SMTP (Simple Mail Transfer Protocol) is used for sending emails.
-
SSH (Secure Shell) is used for secure remote login and command execution.
-
DNS (Domain Name System) is used for translating domain names into IP addresses.
Uses of servers¶
Servers have a wide range of uses.
-
Web hosting: Hosting websites and web applications, making them accessible over the internet.
-
Email hosting: Managing and storing email accounts and messages.
-
Database hosting: Storing and managing large databases for applications and services.
-
File storage: Providing centralized file storage and sharing for organizations.
-
Virtualization: Hosting multiple virtual machines (VMs) on a single physical server, allowing for efficient resource utilization.
-
Cloud computing: In Rumble Cloud, servers provide the computing resources for creating and managing VMs, storage, networking, and other cloud services.
