Cloud Scheduler is a fully managed enterprise-grade cron job scheduler. It allows you to schedule virtually any job, including batch, big data jobs, cloud infrastructure operations, and more.
Automating tasks that re-occur is definitely at the heart of every software developer. Google Cloud Platform has a tool that allows users to schedule jobs while maintaining the usual unix-cron format.
Cloud Scheduler can be referred to as Cronjob as a Service tool, it is fully managed by Google Cloud Platform so you don't need to manage the scheduler's underlying infrastructure.
Cloud Scheduler can be used for multiple use cases such as making requests to an HTTP/S Endpoint, invoking a Pub/Sub topic, making database updates and push notifications, triggering CI/CD pipelines, scheduling tasks such as image uploads and sending an email, or even invoking Cloud Functions.
In this article, we would simply use Cloud Scheduler to make simple requests to an HTTP Endpoint.

In addition, Stackdriver integrates with Cloud Scheduler providing powerful logging for greater transparency into job execution and performance.
Cloud Scheduler is simple and pay-for-use; where you pay for the number of jobs you consume per month. Google Cloud generously also allows you create 3 free jobs per month while you only per for others at $0.10/job/month
