DevOps with Google Functions

Google decided to launch its serverless platform as Cloud Functions, but it is still in its maturing stage. At the time of writing this book, we can only write Google Cloud Functions with Node.js. The functions can be triggered through Google's internal event bus—Pub/Sub and through HTTP as mobile events from Firebase. I am not going to delve much into what Google Functions does, because we have already covered that in earlier chapters. So, in this chapter, we will be covering how we apply DevOps to Google Functions and what are the best practices of deployment, release management, monitoring, and logging. We will look into various examples and a demo with a gcloud command line, Serverless Framework, and Jenkins. So, let's jump in to DevOps.
