Faster Response Time with Reverse Proxy Cache

These resources are then returned to the client as though they originated from the server itself (or servers themselves). While a forward proxy acts as an intermediary for its (usually nearby) associated clients and returns to them resources accessible on the Internet, a reverse proxy acts as an intermediary for its (usually nearby) associated servers and only returns resources provided by those associated servers.

NGINX

NGINX is a high performance, open source web application accelerator that helps over 37% of the world’s busiest websites deliver more content, faster, to its users.

Companies deploy NGINX to manage the complexities and pitfalls associated with HTTP and to make their web applications more responsive, scalable, fast and secure. NGINX is commonly installed between the network and the application to offload concurrency processing, URL switching, HTTP load balancing, SSL termination, caching, and security policies.

APACHE

The Apache HTTP Server Project is a collaborative software development effort aimed at creating a robust, commercial-grade, featureful, and freely-available source code implementation of an HTTP (Web) server. The project is jointly managed by a group of volunteers located around the world, using the Internet and the Web to communicate, plan, and develop the server and its related documentation. This project is part of the Apache Software Foundation. In addition, hundreds of users have contributed ideas, code, and documentation to the project. This file is intended to briefly describe the history of the Apache HTTP Server and recognize the many contributors.

VARNISH

Varnish is an HTTP accelerator designed for content-heavy dynamic web sites. In contrast to other web accelerators, such as Squid, which began life as a client-side cache, or Apache and nginx, which are primarily origin servers, Varnish was designed as an HTTP accelerator. Varnish is focused exclusively on HTTP, unlike other proxy servers that often support FTP, SMTP and other network protocols.

Installing Nginx on Ubuntu 14.04 with Server Caching

Mike Ross — Thu, 02 Jul 2020 04:47:54 +0000

Before you begin this guide, you should have a regular, non-root user with sudo privileges configured on your server. You can learn how to configure a regular user account by following steps 1-4 in our initial server setup guide for Ubuntu 14.04.

Step One – Install Nginx

We can install Nginx easily because the Ubuntu team provides an Nginx package in its default repositories. Since this is our first interaction with the apt packaging system in this session, we should update our local package index before we begin so that we are using the most up-to-date information. Afterwards, we will install nginx:

sudo apt-get update
sudo apt-get install nginx

You will probably be prompted for your user’s password. Enter it to confirm that you wish to complete the installation. The appropriate software will be downloaded to your server and then automatically installed.

Step Two – Check your Web Server

You can access the default Nginx landing page to confirm that the software is running properly by visiting your server’s domain name or public IP address in your web browser.

If you do not have a spare domain name, or have no need for one, you can use your server’s public IP address. If you do not know your server’s IP address, you can get it a few different ways from the command line.
