Technical requirements
This chapter is more code-oriented since often, we will need to give up a more black-box approach to modify the code and collect more application context details.
We will use two sample applications to demonstrate the usage of AWS X-Ray in real scenarios, one implemented in JavaScript/Node.js and another in Java. Code experience with those languages is welcome, but we will keep it simple so that no deep understanding is required.
We will rely on infrastructure automation using CloudFormation. Please check the product page and documentation at https://aws.amazon.com/cloudformation/.
We will also install and configure software on a Linux server, so some basic bash shell experience is welcome.
