# Functions

[Catalyst Serverless Functions](https://docs.catalyst.zoho.com/en/serverless/help/functions/introduction) are custom-built coding structures that contain the business logic of your Catalyst application. They can be created either using the [Catalyst console](https://console.catalyst.zoho.com/baas/index) or the [CLI](https://docs.catalyst.zoho.com/en/cli/v1/working-with-functions/introduction). This section covers the various SDK methods that can be used to implement functions in your Catalyst application.

#### Get a Component Instance

A component instance is an object that can be used to access the pre-defined configurations specific to a particular component. This process will not fire a server-side call. 

The `app` reference used in the code below is the [Python object](https://docs.catalyst.zoho.com/en/sdk/python/v1/setup/#initializing-the-sdk) returned as a response during SDK initialization. You can create a new `function_service`instance as shown below. This component instance will be used in the next section while executing the function.

```python
#Get function component instance 
function_service = app.functions()

```
