Any good thriller starts by introducing its primary protagonists. Their motivations, backgrounds, and strengths and weaknesses are presented. The environment in which the key players operate is shown in the first 20 minutes.
This is what the first part of the book is about. The first chapter introduces our hero, Fluentd (and sibling Fluent Bit); we set the scene with the context, the use cases, and so on. If you are still in the process of discovering what Fluentd is about or thinking about the things that will help you make a case to your colleagues for adopting Fluentd, there is plenty of fuel for thought here.
If chapter 1 is about our principal player, then chapter 2 looks at the environments in which Fluentd can operate. We will progress through the first practical steps by installing Fluentd and keep with the time-honored tradition established by Brian Kernighan, with the first solution being “Hello World.”
