It’s important to validate the health of a system from a customer perspective and confirm that customers are able to connect. This is more difficult when the customers don’t constantly call the endpoint. Amazon CloudWatch Synthetics supports the creation of canaries, which can test both public and private endpoints. By using canaries, you can know the status of a system even if it isn’t in use. These canaries are either Node.js Puppeteer scripts or Python Selenium scripts.
