Introduction

All online businesses need to account for growth. As a business receives more visitors to its site, the underlying infrastructure needs to scale to provide the same level of performance that the visitors are accustomed to. Horizontal scaling, the addition of more servers rather than increasing the power of the existing servers, is an easy way to build our web servers’ ability to handle a more significant amount of traffic and protect us against hardware failure. Ensuring that the additional web servers have the same files and data is a potentially time-consuming and challenging task. Automating that task using free, open-source software, such as lsyncd, is a way to ensure that we have a safe, secure, and repeatable method of copying files from one server to another.

This percentage is constantly increasing as clients are in need of a web server that can serve content faster. It can also be used for proxies, reverse proxies, load balancing, and more depending on what modules you load onto NGINX. One of the significant differences between Apache (a popular webserver) and NGINX is the way each system handles access rules. If you are familiar with using .htaccess rules in Apache, then the method that NGINX uses of including directives in the server’s vhost block will be substantial change.

Reading Time: 6 minutesA Squid Proxy Server is a feature rich web server application that provides both reverse proxy services and caching options for websites. This provides a noticeable speedup of sites and allows for reduced load times when being utilized.

Squids reverse proxy is a service that sits between the Internet and the webserver (usually within a private network) that redirects inbound client requests to a server where data is stored for easier retrieval. If the caching server (proxy) does not have the cached data, it then forwards the request on to the webserver where the data is actually stored. This type of caching allows for the collection of data and reproducing the original data values stored in a different location to provide for easier access.
