Erlang and OTP in Action

Chapter 8. Introducing distributed Erlang/OTP

This chapter covers

• The basics of distributed Erlang
• Working with Erlang nodes and clusters
• Implementing a simple resource discovery system

In this chapter, we take a break from adding functionality to the cache application. Instead, we explore the distributed programming capabilities of Erlang, in order to prepare you for the next chapter. Although Erlang/OTP makes distribution a lot simpler than it is in most other languages, it’s still a complex topic. This chapter will teach you the basics of working with distributed Erlang, but it can take a lot of experience to get the hang of it and realize how few of the lessons from traditional sequential programming remain valid. But don’t worry—above ...
