What are components?

Components form the most basic building blocks in OneOps. We have had brief encounters with components before in the circuit directory. Here we will deep dive into components. As mentioned in the OneOps documentation, a component has three aspects--a component class, a component resource, and a component instance. This kind of structure will be instantly recognizable to people familiar with the object-oriented style of programming. In object-oriented programming objects are always instantiated from classes. Similarly, the equivalent of a class in OneOps is a component. Just like a class has variables and methods associated with it, so does a component. Since the backend of OneOps is, currently, heavily modeled in Chef, a OneOps component is a Chef cookbook modified to work with OneOps. In the next chapter, you will be creating your own components from scratch. However, before you start creating your components, you should understand their structure. At the time of writing...
