Compute

Watch the presentation Se presentationen på svenska In IT, servers provide the computing power behind applications, websites, and databases. This article breaks down the server concept, focusing on its role as a compute resource, from physical machines to serverless functions. The Purpose of a Server A server is a compute resource designed to process requests and deliver services to other devices, called clients, over a network. Traditionally, servers were physical machines, but now they include virtual machines, containers, and serverless functions. »

Watch the presentation Se presentationen på svenska Servers are designed to fulfill specific roles that cater to the needs of businesses and applications. These roles provide a range of services. Here’s a brief overview of the most common server roles. At the end we make a deeper dive into Web Servers, Application Servers, Reverse Proxies and Bastion Hosts. Overview of Common Server Roles Web Server A web server hosts and serves web pages or applications over the internet or intranet. »

Watch the presentation Se presentationen på svenska Physical servers are built to handle extensive workloads, host applications, store data and much more. Understanding the components within a server is essential for planning, troubleshooting, and management. This article breaks down the internal parts of a physical server and their function. Core Components of a Physical Server Every part of a physical server works in tandem to deliver reliable performance. The CPU processes tasks while RAM temporarily holds data to speed up operations. »

Server Roles Servers often carry out a specific task tailored to business and application needs. This is commonly known as the server role Key Server Roles Web Server: Serves web pages or applications to clients. Application Server: Manages and runs business logic for apps. Proxy Server: Intermediary enhancing security and performance. Bastion Host: Secure access point for internal network management. Database Server: Stores and manages structured data. File Server: Centralized file storage and sharing. »

Inside a Physical Server Physical servers are engineered for reliability and heavy workloads. Components work together to host applications, store data, and process tasks. Core Components CPU: Executes instructions and manages tasks. RAM: Temporary storage for active processes and data. Storage Drives: Persistent data storage. Motherboard: Central communication hub. PSU: Converts power for server use. Cooling Systems: Maintains optimal temperatures. NICs: Handles network connectivity. Expansion Slots: Adds versatility for specialized components. »

Inuti en fysisk server Fysiska servrar är utformade för tillförlitlighet Kärnkomponenter CPU: Utför instruktioner och hanterar uppgifter. RAM: Tillfällig lagring för aktiva processer och data. Lagringsenheter: Permanent datalagring. Moderkort: Central kommunikationshub som förbinder de övriga komponenterna PSU: Omvandlar ström. Kylsystem: Upprätthåller optimala temperaturer. NICs: Hanterar nätverksanslutning. Expansionsplatser: Ger möjlighet att ansluta fler komponenter. CPU Serverns “hjärna”. Flerkärniga processorer hanterar parallella uppgifter. Exempel: Intel Xeon, AMD EPYC. RAM Lagrar temporärt data för snabbare bearbetning. »

Vad är en server? Servrar tillhandahåller datorkraften bakom applikationer, webbplatser, databaser och mycket mer. En server behandlar klientförfrågningar och levererar tjänster via ett nätverk. Viktiga egenskaper Beräkningskraft: Utrustad med CPU, minne och lagring för att utföra olika uppgifter. Nätverksuppkopplad: Möjliggör kommunikation med klienter och andra tjänster. Tjänstebaserad: Tillhandahåller applikationer, databaser, fillagring, etc. till användare. Typer av servrar Fysiska servrar Virtualla servrar Containrar Serverlösa funktioner (Serverless) Fysiska servrar (Bare-Metal) Dedikerad hårdvara som kör applikationer och lagrar data. »

Serverroller Servrar utför ofta en specifik uppgift anpassad till ett affärs- eller applikationsbehov. Detta kallas vanligtvis för en serverroll. Viktiga serverroller Webbserver: Levererar webbsidor till klienter. Applikationsserver: Hanterar och kör affärslogik för större applikationer. Proxyserver: Mellanhand som förbättrar säkerhet och prestanda. Bastion Host: Säker åtkomstpunkt för hantering av servrar på interna nätverk. Databaseserver: Lagrar och hanterar strukturerad data - databaser. Fildelningsserver: Centraliserad lagring och delning av filer. DHCP-server, E-postserver, DNS-server, Utskriftsserver, FTP/SFTP-server, Domänkontrollant, Mediadelningsserver, etc. »

What is a Server? Servers provide the computing power behind applications, websites databases and much more. A server processes client requests and delivers services across a network. Key Characteristics Processing Power: Equipped with CPU, memory, and storage to execute tasks. Networking: Enables communication with clients and other services. Service-Oriented: Provides applications, databases, file storage, etc to users. Types of Servers While traditionally physical, servers now include virtual machines, containers, and serverless functions. »
