Overview of the CloudScript build language for the Cloud.

1. Getting Started with
CloudScript
Nick Peterson, Director of Engineering

2. Our Story
Hosting industry veterans each averaging 8+ years of
managed hosting & cloud infrastructure experience
Making infrastructure easy to deploy and manage for
Developers, DevOps, and Operations folks alike
Providing robust Infrastructure as a Service for high
performance cloud computing applications since 2010

3. What is CloudScript?
CloudScript is a Domain Specific Language
(DSL) for orchestrating application infrastructure.
● External DSL syntax like Make
or Ant
● Engine has Threads, Tasks,
Agents
● Resources include, Keys,
Scripts, Recipes, Servers,
Storage Objects, Networks
● Methods include, Create,
Read-Or-Create, Delete
● Embedded language support
includes, Puppet, Chef, Shell,
Python, Ruby, etc.

4. Design Principles
1. Dependency based programming model
allows programmers to specify prerequisites
2. Idempotent methods on all resource types
allows repetition w/o side effects to reach the
desired outcome for your environment
3. Code enveloping increases the power without
reducing the expressivity of the DSL
4. Distributed agents and centralized event
processing allow for software pipelines

5. Hello World!
cloudscript apache_web_server
version = _LATEST /server/cloud web_server read_or_create
result_template = apache_result_template hostname = 'helloworld'
image = 'Linux Ubuntu 12.04 LTS 64-bit'
globals service_type = 'CS01'
server_pass = lib::random_password() keys = [server_key, console_key]
console_pass = lib::random_password() recipes = [web_server_template]
thread provision_web_server text_template web_server_template
#!/bin/sh
tasks = [configure_web_server] apt-get update; apt-get -y install apache2
/etc/init.d/apache2 start
task configure_web_server cat <<EOF>/var/www/index.html
Hello World!
/key/password server_key read_or_create EOF
key_group = _SERVER exit 0
password = server_pass _eof
/key/password console_key read_or_create text_template apache_result_template
key_group = _CONSOLE Your web page is located at:
password = console_pass http://{{ web_server.ipaddress_public }}
_eof
