With the chapter almost at the end, here are few key next steps that I feel are worth trying out before we jump over to the next chapter. Firstly, create your own Lambda functions and deploy them either by using APEX or Claudia.js. This will help you in understanding versioning and aliases a bit better along with added simplicity to deploying functions as we move along this book. Additionally, there are other deployment tools and services present out there such as lambda-tools, gordon, and serverless which we will be covering in the later chapters.
