Scheduling things in a Serverless environment/Lambdas

Scheduling things in a Serverless environment/Lambdas

Ever wondered how to schedule things when you are working in a serverless environment?

Run the scheduler in the backend itself. You can use various task scheduler libraries. This makes sense because your server is always running. Use CRON jobs on the machine itself to invoke a certain service or webhooks. Both of these options are not possible in the case of lambdas as there are no dedicated machines and the server only runs on demand. Solution AWS CloudWatch comes to rescue here which lets you send scheduled events to lambda, which will invoke your app and you can perform any routine actions that you want.

A Deep Dive into Serverless Tracing with AWS X Ray & Lambda. Over the past few weeks I’ve been experimenting with building a Serverless API on AWS with the goal of having everything needed to run a production system. One necessary piece was distributed tracing. While I’d seen a bit of what some non-AWS options had to offer, the extra cost of the services themselves, along with actually getting the data to them, was a bit prohibitive for what I imagined should be possible (and cheaper) with only AWS, which brought me to X Ray.
