mkaciuba - website

Marcin Kaciuba Apr 1, 2017

This project was the longest (except my master degree) I have ever done. The website is composed of few elements and I was trying to learn as much as I can while doing it.

Big picture

Cloudflare

As a first line of defence I’m using the Cloudflare. It is a global Content Delivery Network that helps my site to be faster in all corners of the globe. I’m using CDN for cache all static content and it provides DNS very easy to use. Furthermore by using the Cloudflare I’ve got free wildcard certificate. Maybe in times of Let’s Encrypt it isn’t surprising but it is working without any effort from me.

 

NGINX

As HTTP server I’m using nginx. It is very fast non-blocking HTTP server that gives a lot of opportunities to customize traffic. It can be greatly extended by the use of a little scripting in LUA. I’m using LUA  to check which type is user’s device and check if I should redirect it to HTTPS. I’m still thinking about doing more.

 

PHP

My application is written in PHP using Symfony framework. Symfony has very mature approach to process request. I’m calling it enterprise PHP. Biggest advantages of Symfony is that it has a very big community that provides great support and libraries for everything.I will provide more information about backend in next section of this post.

 

Databases

Redis - very fast in memory key-value store.  I’m using it as cache for many types of objects. For example: cache for ORM result, for rendered HTML, for block etc.

MySQL - most common relational database being used in web services.

Elastica (elasticsearch) - document “databases” of my application are using it for full text search across content.

Beanstalkd  -  very simple messages queue.

 

Backend application

While building this application, I was paying attention to make it easy to use and very like some popular CMS. I have one though in my head “All things it should accomplish by using panel”. I’m caching every request to database so when I’m editing, content/gallery application creates purge request that is going to queue, and then worker is purging it from local nginx and Cloudflare. Task queue isn’t used only to purging but I can add images to gallery from a ZIP archive. Worker extracts files and adds it to a database and then process some predefined transformations on images

Performance comparison

I was testing my application with latest docker images of wordpress. Without cache my application is 2x faster than wordpress. So it’s quiet good.  

No cache - wordpress
