Slides for the lightning talk "A practical 10m intro to PHP on Heroku" See the version with animated gif at http://yet.another.linux-nerd.com/blog/a-10-minutes-intro-to-heroku-php-hosting

1. a 10 MINUTES intro
to Heroku PHP hosting
a 10 MINUTES intro
to Heroku PHP hosting

2. So you made a
shiny new app
And you installed on
a dedicated server.

3. YOU MAY
HAVE ISSUES

4. Failing hardware
○ RAID drives down
○ Fan broken
○ Network card KO
○ Motherboard burnt
○ DDOS

5. Software to patch
○ PHP
○ Apache / Nginx
○ MySQL, MongoDB
○ Linux
○ Bash
○ OpenSSL
○ ...

6. Hi !
I am Olivier Garcia
I am here because I’ve been
through that before.

7. SOMETIMES, it’s better to
○ Delegate hardware & platform management
○ Focus on code & customers, not technical scaling

8. Platform As A Service
Run Web applications without building and
maintaining the infrastructure

9. PaaS
You’re given a repo
You push your code
e.g. Heroku, Azure
IaaS
You’re given a server
You install a Linux
e.g. OVH, AWS
Comparing /.+ as a Service/
SaaS
You’re given software
You use it
e.g. Gmail, Salesforce

10. Introducing
Heroku

11. Languages
○ PHP
○ JS
○ Go
○ Python
○ Java/Scale
○ Closure
and more !
Runs most of the OSS tech stack
DB
○ MySQL
○ PostgreSQL
○ MongoDB
○ Redis
○ Solr
○ Graphite
and more !

12. ○ Everything can be
done in CLI &
automated
Insanely easy to work with
○ Great documentation
○ Huge list of add-ons

13. 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

14. 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

15. Some cost
examples

16. Toy projects
0 $
○ CPU: 1 core
○ RAM: 512Mo
○ DB: 64GB
○ Support by mail : 1+ day

17. Small projects
○ CPU: 8 cores
○ RAM: 6 Go
○ DB: 64 GB
○ Custom SSL Domain
○ Support by mail : 1+ day
770 $

18. Big projects
○ CPU: 4 x 8 cores
○ RAM: 4 x 6 Go
○ DB: 1 TB
○ Custom SSL Domain
○ Support in 1H
5220 $

19. DEMO
I previously
○ Created an account
○ Installed the heroku pkg

20. DEMO FALLBACK
Well, it’s not working as
planned, let’s fall back on
slides...

21. Setup project
$ mkdir -p ~/Code/heroku-demo/web
$ cd ~/Code/heroku-demo
$ git init .
$ heroku create php-10m-demo

22. composer.json
{
"require" : {
},
"require-dev": {
"heroku/heroku-buildpack-php": "*"
}
}

23. Procfile
web: vendor/bin/heroku-php-apache2 web/

24. web/index.php
<?php
phpinfo();

25. Add files to project
$ git add web Procfile composer.json
$ git commit -m “Added: Project files”

26. Deploy !
$ git push heroku master

27. See the deployed app
$ heroku open

28. Scale up & down
$ heroku ps:scale web=10
$ heroku ps:scale web=1
$ heroku ps:scale web=0

29. Get logs & run command
$ heroku logs
$ heroku run bash
$ heroku run app/console cache:clear
