An important year in software

1991

Hello everybody out there using minix - I’m doing a (free)

  • perating system

(just a hobby, won’t be big and professional like gnu) for 386(486) AT clones.

~21 years later: Linux has won

slide-11
SLIDE 11

Linux runs everywhere

(even old versions, on crashy airline entertainment systems...)

#P0WN ALL TEH GADGETZ !

slide-12
SLIDE 12

The Penguin is triumphant!

(maybe not this one…)

slide-13
SLIDE 13

Linux is ubiquitous

(but often invisible)

slide-14

It works.

  • 2. What about Cloud?
slide-16
SLIDE 16

3 layers

IaaS, PaaS, SaaS

Infrastructure Platform Software

Gmail, Salesforce, Flickr, Google Docs... Amazon EC2, Google CE, OpenStack, vSphere, Joyent, Cloud Stack, Eucalyptus... Google AppEngine, Heroku, Cloud Foundry, EngineYard, Apprenda...

slide-17
SLIDE 17

How did we get here?

slide-18
SLIDE 18

Infrastructure Clouds

  • consumer web companies built out according to

their own needs to support Software

slide-19
SLIDE 19

But - still need to build & manage Platform

slide-20
SLIDE 20

Why is it so hard...?

A real deployment flow (!)

slide-21
SLIDE 21

An alternative approach...

Cloud Foundry can make it simpler!

cf#iaas.yml provision0<my0cloud> add_capacity0<my0cloud> target0<my0cloud> push0<my0app> create0<my0services> bind0<my0services> scale0<my0app>0+100

OPERATOR DEVELOPER

Cloud Deployment: 2-4 hours App Deployment: 30-90 seconds

All the pieces to make your own!

“if you can’t open it, you don’t own it” (O’Reilly MAKE)

slide-25
SLIDE 25

Open & public from the start

Code all on Github

slide-26

Google AppEngine, Heroku, Cloud Foundry, OpenShift, Stackato, Cloudbees, AppFog, Elastic Beanstalk, anyNines, Apprenda...

slide-27

Not all PaaSes are created equal...

Run on: AWS, OpenStack, vSphere... more to come!

Buildpacks

Buildpacks are responsible for preparing the machine image for an application

Compatibility

Cloud Foundry buildpacks follow the Heroku buildpack design

Cloud Foundry and Heroku buildpacks are compatible (if you take care to make them compatible) Other PaaS providers are adopting the buildpack design - emerging convention

Built-in Buildpacks

slide-36

Tested Buildpacks

https://github.com/cloudfoundry-community/cf-docs-contrib/wiki/Buildpacks

Languages Containers

Haskell

slide-37

Java Buildpack

Supports a variety of JVM languages, containers, and frameworks with a modular, configurable, and extensible design

slide-38
SLIDE 38

Java Buildpack Concepts Containers Frameworks JREs

OpenJDK, etc.

Java main() Tomcat Groovy Spring Boot CLI Play Spring config Play config Play JPA config New Relic

slide-39
SLIDE 39

Container Detection Criteria

Java main()

META-INF/MANIFEST.MF exists with Main-class attribute set

Tomcat

WEB-INF directory exists

Groovy

.groovy file with a main() method, or .groovy file with no classes, or .groovy file with a shebang (#!) declaration

Spring Boot CLI

  • ne or more POGO .groovy files

with no main() method, and no WEB-INF directory

Play

start and lib/play.play_*.jar exist

Choose zero or one

slide-40
SLIDE 40

Framework Detection Criteria

Spring

spring-core*.jar exists

Play config

Play application detected

Play JPA config

play-java-jpa plugin exists in app

New Relic

New Relic service bound to app

Choose all that apply

slide-41
SLIDE 41

Customization

Two ways to customize the Java buildpack Configure artifacts used by standard JREs, Containers, and Frameworks Extend the buildpack with your own JREs, Containers, and Frameworks

Customization is done by forking the buildpack

Spring and the Cloud

  • Goal: deploy Spring apps to the cloud without

changing a single line of code

  • Cloud Foundry automatically re-configures bean

definitions to bind to cloud services

  • Works with Spring and Grails
