Overview

AWS Event Cache features

The AWS Event Cache Plugin provides the following features:

• Manual cache refresh within Spinnaker
  • Enables fetching the latest data from AWS providers
  • Useful in scenarios where you’ve reached rate limits and need real-time data
• Dynamic polling interval adjustment for data retrieval from AWS providers
  • Provides flexibility in managing the frequency of API calls, helping to mitigate rate limit issues
• Seamless integration with AWS SNS for event-driven communication
  • The plugin receives notifications from SNS whenever a change is made, ensuring timely responses to rate limit issues.
• An event scheduler
  • Coordinates with the notification handling service
  • Designed to be invoked by AWS SNS, ensuring efficient processing of events related to rate limit changes
• Different configurations for non-production environments
  • You can set a longer polling interval in non-production environments to reduce the frequency of API calls without compromising overall functionality.

The plugin uses AWS Config to send events to Spinnaker through a new endpoint in the Gate service.

How the plugin works

AWS SNS Integration

The plugin seamlessly integrates with AWS SNS to establish a reliable communication channel. AWS SNS is configured to send notifications whenever a change is detected in the AWS environment, such as rate limit adjustments or IAM role modifications.

Event Scheduler Initialization

Upon receiving a notification from AWS SNS, the plugin’s event scheduler is initialized. This scheduler acts as the orchestrator, coordinating the subsequent actions to manage rate limit issues. Event Handling Workflow:

The Event Scheduler triggers an event handling workflow that consists of the following steps:

1. Event Validation: The plugin validates the incoming event, ensuring it is legitimate and corresponds to a relevant change in the AWS environment.
2. Decision Logic: The plugin determines the appropriate action to take based on the type of event, such as rate limit increase or IAM role modification.
