Designing Elixir Systems with OTP, in beta; What is GraphQL? on video

April 17, 2019

The concept of scaffolding is ancient; there's evidence that the paleolithic painters of the Lascaux caves used scaffolding of some sort. Scaffolding of one kind or another was used to build the pyramids of Egypt and the medieval cathedrals in Europe. In the early 1900s, metal poles became common for scaffolding, and Daniel Palmer-Jones, along with his brother David, invented a universal method of coupling the poles together for greater strength. Their scaffolding system was used for repairs on Buckingham Palace in 1913, and the standardized couplings caught on. Today, over one hundred years later, the same system is still standard for construction.

If you've got a good framework, it lasts a long time. The OTP stands for "Open Telecom Platform" and was developed by Ericsson in 1995. Like all good scaffolding, the OTP provides stability and reliability to your Elixir code. When you understand how the scaffolding is built, you can adapt your design to take advantage of that and create faster, more reliable products.

Designing Elixir Systems with OTP: Write Highly Scalable, Self-Healing Software with Layers

Elixir is gaining mindshare as the programming language you can use to keep your software running forever, even in the face of unexpected errors and an ever-growing need to use more processors. This power comes from an effective programming language, an excellent foundation for concurrency and its inheritance of a battle-tested framework called the OTP.

If you're using frameworks like Phoenix or Nerves, you're already experiencing the features that make Elixir an excellent language for today's demands. This book shows you how to go beyond simple programming to designing, and that means building the right layers. Embrace those data structures that work best in functional programs and use them to build functions that perform and compose well, layer by layer, across processes. Test your code at the right place using the right techniques. Layer your code into pieces that are easy to understand and heal themselves when errors strike.

Of all Elixir's boons, the most important one is that it guides us to design our programs in a way to most benefit from the architecture that they run on. The experts do it and now you can learn to design programs that do the same.
