AWS Step Functions for networkers – Workflow definition
AWS has many great tools and products that may simplify your task. In day to day work, no matter if you are networks engineer, software administrator or have a different role in your organization you will perform small repetitive tasks to complete the bigger project. Writing a long, complex scripts or programs is a solution, but it is flexible? Step Functions is a good option in such cases.
Good programming rule is to create small functions to complete small chunk of work and then pass it on another one. So instead of writing one script that will log into 100 devices to fetch firmware version you create a small function that does it for one device and then you call it in a loop in other function passing the new IP as an argument. That is exactly what AWS Step Functions are meant for. Using this service you can create a flow of small tasks, each dependent on other if required, to complete bigger work. Let me show you the basics and how you can use it.
