Load balancing distributes incoming network traffic across multiple servers to ensure no single server becomes overwhelmed. This technique enhances application availability, scalability, and reliability. Nginx, a high-performance web server, can also function as an effective software load balancer for applications like those built with Spring B ...

Basic Concepts Load balancing solutions encompass various approaches including DNS-based domain rotation, client-side load distribution, application-layer load balancing, and IP address-based scheduling. This document focuses on LVS, a layer-4 load balancer built upon transport protocols like TCP/UDP. LVS stands for Linux Virtual Server, repres ...

Apache Reverse Proxy and Load Balancing 1. Reverse Proxy Overview A reverse proxy is a server that receives requests from clients on the internet and forwards them to servers on an internal network. It then returns the server's responses to the requesting clients. From the external perspective, the reverse proxy appears as the original server ...

The following procedure outlines the deployment of an Apache HTTP Server instance configured as a reverse proxy and load balancer for multiple backend application servers. The architecture utilizes a front-end proxy layer distributing traffic across two back-end web nodes. Environment Preparation and Back-End Node Configuration Initialize two L ...

Load balancing distributes network traffic or compuattional tasks across a cluster of servers. This ensures optimal resource utilization, minimizes response times, and prevents system bottlenecks. Below are six fundamental algorithms used in modern distributed architectures. 1. Round Robin The Round Robin strategy cycles through the available s ...

DNS and Domain Resolution When a user initiates a request via a URL, the first step is resolving the domain name to an IP address via the Domain Name System (DNS). DNS operates at the application layer, translating human-readable hostnames into machine-readable IP addresses. While direct IP access is possible, domain names provide a layer of ab ...

Nginx Configuration File Locations: The location of Nginx configuration files varies depending on the installation method. Source Code Compilation: Typically found in /usr/local/nginx/conf directory. Yum Installation: Usually in /etc/nginx/ directory (main configuration file) and /etc/nginx/conf.d directory. Docker Container: Generally located ...

In a distributed architecture where multiple backend instances handle incoming traffic, maintaining a consistent authentication state is a common challenge. Typically, a standard implementation involves issuing a unique token to the user upon a successful login. This token is stored in a centralized cache, such as Redis, and the client must inc ...

Load Balancing Fundamentals Global Server Load Balancing (GSLB) GSLB operates across geographically distributed infrastructure with the following components: Global Coordinator: Oversees the entire traffic distribution system Regional Dispatcher: Manages traffic within a specific geographic area Application Controller: Routes requests to appro ...

Nginx functions as a reverse proxy by positioning itself infront of origin servers. It intercepts client requests, forwards them to the appropriate backend server, and returns the server's response to the client. This abstraction shields the client from the direct existence of the backend infrastructure. Load balancing is achieved using Nginx's ...
