The world around us is changing at the speed at which the Internet changes.

This is normal because most of the work is based on the skills of people who are searching for better ways to encode, program and display sites.

What is certainly an indication of the quality of the site, in a technological sense, is its speed. That's why we decided to introduce you four technologies that can accelerate the operation of your site.

HTTP/2

In May 2015, a new version of HTTP protocol was published, which has support from the second half of that year. The biggest advantage of the HTTP/2 protocol is that it can cover multiple requests over a single connection. This novelty is called multiplexing (performing multiple actions simultaneously) and represents a revolution in web design (sprites and data URL looks will no longer be effective).

Unlike the HTTP/1 protocol, which was better able to load one large image than a few smaller ones that could not be loaded at once, HTTP/2 solves this problem and compresses the headers before sending data, which in turn simplifies data transfer. The new version of the protocol is binary, unlike the first that was textual.
And what the result is? Acceleration of performance is up to 50%. Check on http2demo.

A problem when switching to HTTP/2 has nothing to do with the protocol itself as such. Namely, although he does not require the site to be provided, web browsers support it only through the SSL protocol for the encryption of computer networks.

BROTLI

Another data compression algorithm released in autumn 2015. Google has designed this algorithm to reduce the size (weight) of data being transmitted and, according to officials, has compression capabilities of 20 to 26%, which on the other hand saves about 40 % of traffic HTML files and about 25% of CSS and JavaScript.

CDN

CDN (Content Delivery Network) is a network of proxy servers located in different centers around the world. CDN servers contain copies of content from your site (images, videos, software, etc.) and, in order to increase the response speed, when you access it, the nearest server that can deliver the data and reduce the response speed as little as possible is called.

Another advantage of this network is to improve the reliability of the site. When the content breaks down on several servers, web hosting is spared traffic and is better protected against falling. Using CDN servers, sites can accelerate up to 50% on average.

SSL

The last item on the list of technologies is SSL encryption between the server and the client. This certificate can be set up in agreement with your hosting provider or for free. Although he does not represent the novel in the true sense of the word, HTTP/2 and Brotli cannot be used without it.

Since it moved from the beta stage in April last year to public use, the Let's encrypt site became popular, among other things, because it provides SSL certificates for free and very fast. The process is simplified, automated and lasts only a few minutes.
