Course (certified) on Tech Diplomacy

The implementation of applications or services with a strong presence on the Internet, such as social network applications, present great challenges: design and programming of back-ends (services) that support the popularization of the application, and design and programming of front-ends (mobile applications and web applications) with a good user experience, elegant interfaces, and efficient access to the back-end. The course focuses on the design and programming of the back-end of this type of applications. We list some of the fundamental requirements: 1. Availability (always attending requests) 2. Reliability (fault tolerant) 3. Scalability (huge numbers of simultaneous requests). 4. Maintainability (easily adaptable to new requirements) 5. Accessibility (well-structured APIs for the front-end service). The course delves into the Erlang/OTP ecosystem and the Elixir language. Elixir takes advantage of the Erlang virtual machine, well known for its ability to run low-latency, distributed, and fault tolerant systems. Some examples of applications and systems where these languages have been used are: WhatsApp, Cabify, bet365, Nintendo Switch multi-user online gaming or RabbitMQ.
