a 10 MINUTES introto Heroku PHP hostinga 10 MINUTES introto Heroku PHP hosting
So you made a shiny new app
And you installed on a dedicated server.
YOU MAY HAVE ISSUES
Failing hardware
○ RAID drives down○ Fan broken○ Network card KO○ Motherboard burnt○ DDOS
Software to patch
○ PHP○ Apache / Nginx○ MySQL, MongoDB○ Linux○ Bash○ OpenSSL○ ...
Hi !I am Olivier Garcia
I am here because I’ve been through that before.

SOMETIMES, it’s better to
○ Delegate hardware & platform management
○ Focus on code & customers, not technical scaling
Platform As A Service
Run Web applications without building and maintaining the infrastructure
PaaSYou’re given a repo
You push your code
e.g. Heroku, Azure
IaaSYou’re given a server
You install a Linux
e.g. OVH, AWS
Comparing /.+ as a Service/
SaaSYou’re given software
You use it
e.g. Gmail, Salesforce
Introducing
Heroku
Languages○ PHP○ JS○ Go○ Python○ Java/Scale○ Closureand more !
Runs most of the OSS tech stack
DB○ MySQL○ PostgreSQL○ MongoDB○ Redis○ Solr○ Graphiteand more !
○ Everything can be done in CLI & automated
Insanely easy to work with
○ Great documentation
○ Huge list of add-ons
Load balancing
Requests are load balanced on all nodes, no custom rules can be made
When it’s is not the right solution
Custom components
It may take some time/skills to add special components
eg. mod_deflate for Apache
Size
Your app must hold in 100MB
Caching
You may need Varnish and a CDN on top of your app
When it’s is not the right solution
No custom hardware
The only way to get more RAM or CPU is to buy new instances
Price
With a lot of traffic or processing, the hosting will get expensive quickly
Some cost examples
Toy projects
0 $
○ CPU: 1 core○ RAM: 512Mo○ DB: 64GB ○ Support by mail : 1+ day
Small projects
○ CPU: 8 cores○ RAM: 6 Go○ DB: 64 GB○ Custom SSL Domain ○ Support by mail : 1+ day
770 $
Big projects
○ CPU: 4 x 8 cores○ RAM: 4 x 6 Go○ DB: 1 TB○ Custom SSL Domain ○ Support in 1H
5220 $
DEMO
I previously
○ Created an account
○ Installed the heroku pkg
DEMO FALLBACK
Well, it’s not working as planned, let’s fall back on slides...
Setup project
$ mkdir -p ~/Code/heroku-demo/web
$ cd ~/Code/heroku-demo
$ git init .
$ heroku create php-10m-demo
composer.json
{
"require" : {
},
"require-dev": {
"heroku/heroku-buildpack-php": "*"
}
}
Procfile
web: vendor/bin/heroku-php-apache2 web/
web/index.php
<?php
phpinfo();
Add files to project
$ git add web Procfile composer.json$ git commit -m “Added: Project files”
Deploy !
$ git push heroku master
See the deployed app
$ heroku open
Scale up & down
$ heroku ps:scale web=10$ heroku ps:scale web=1$ heroku ps:scale web=0
Get logs & run command
$ heroku logs$ heroku run bash$ heroku run app/console cache:clear
