### Inputs
Inputs put things in motion.

Naming Convention: None

Features:
  * CloudWatch Events Rules
    * Can be API calls or responses to AWS Config
    * From external accounts, puts the event on the main account's event bus.
  * "Custom" entry (Message sent to SNS topic), such as a request to scan for an issue.

### SNS Distribution
There are SNS Topics to distribute from the inputs:

Naming Convention: `fcm-input-[eventName]` or `fcm-input-custom-[typename]`

Features:
  * For each API eventName, named `fcm-input-[eventName]`
  * For each custom type, named `fcm-input-custom-[typename]`

### SQS Queues for Analysis:
SQS queues allow a many-to-one relationship between analysis functions and inputs. A single event/input can fan out to multiple functions.

Naming Convention: `fcm-analysis-[functionname]`.

Function Name:
  * Each analysis function, there is an sqs queue named `fcm-analysis-[functionname]`.
  * This SQS queue can be subscribed to one or more SNS topic. It is up to the function to determine what it is able to process.

### Analysis Functions:
Provide a read-only analysis of the input event.

Naming convention: `fcm-analysis-[functionname]`

  * Lambda functions process the analysis SQS queues.
  * As output, they report result of analysis to the Reporting SNS Topic.
  * If remediation is warranted and possible, send entry to appropriate Remediation SQS Topic.

### SQS Queues for Remediation
Provide a queue for remediation, if applicable.

Naming Convention: `fcm-remediation-[functionname]`

  * Lambda function to process output from analysis function and remediate.
  * Report output to Reporting SNS Topic.

### Reporting SNS Topic
Allows fanout of the reporting, or direct subscription based reporting.

Naming Convention: `fcm-reporting`

### Reporter SQS Queue
One or more queues, subscribed to the reporting SNS topic. Each queue goes to an individual reporter function.

Naming Convention: `fcm-reporting-[functionname]`

### Reporter Function
A function that formats and records the results.

Naming Convention: `fcm-reporting-[functionname]`
