Flexible job scheduling for one-time and recurring tasks
Last updated 24 September 2017
The Kronus add-on is currently in beta.
Kronus is an add-on that provides flexible job scheduling for one-time and recurring tasks.
Kronus handles job scheduling for your application by storing jobs and triggering them at a future time. At the scheduled time, Kronus calls back to your application at a provided URL with optional HTTP headers and payload (if you provide them).
By outsourcing the critical task of job scheduling, you can save valuable development time, as well as infrastructure costs associated with building, deploying, and running a dedicated enterprise job-scheduling system.
Easy to use
With straightforward interfaces, you can configure both one-time and recurring jobs in minutes.
Protect your services
You can use either Basic or Digest authentication with your services. Just include the necessary HTTP header in your job’s specification and Kronus does the rest.
It’s easy to move your jobs to another environment: just export the jobs, change the URLs, and import to another application.
Scale with ease
Kronus scales as your application does.
Using REST protocol, integrating with your web application is easy and straightforward. Take a look at our API documentation at http://docs.kronus.apiary.io.
Faster than competitors
Kronus reach your API faster than the competitors, approximately 38 seconds earlier.
