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. CloudScript is a Domain Specific Language (DSL) for orchestrating application infrastructure. What is CloudScript? • 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. 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 Design Principles
