CloudScript is a domain-specific language for defining and orchestrating infrastructure resources like servers, storage, and networks. It uses an external DSL syntax similar to Make or Ant with threads, tasks, and agents to deploy resources which include keys, scripts, recipes, and servers. Design principles include dependency-based programming, idempotent resource methods, and code enveloping to increase power without reducing expressivity. A Hello World example provisions an Apache web server.

Getting Started with CloudScript
- 1. Getting Started with CloudScript Nick Peterson, Director of Engineering
- 2. Our Story Hosting industryveterans 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? CloudScriptis 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. Dependencybased 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
