Website monitoring services

As an Event Driven Architecture example

Tech stack:

Serverless, AWS Lambda (Nodejs, Javascript), AWS SNS.

All services are independent, so you can spin up and test independently I use the Serverless framework so you can follow the included readme file on each service to run it

Monitoring service

• Monitoring website performance by making GET requests every x of minute
• Publish the monitoring result into AWS SNS

Store API service

• Consume the monitoring results as an event
• Save it into persistence storage (for simplicity now we use json file to save just the last result/visit)
• Show the result on HTTP GET request

Notifier service

• send email notification to the users if the webiste is down

This template does not include any kind of persistence (database). For more advanced examples, check out the serverless/examples repository which includes Typescript, Mongo, DynamoDB and other examples.
