We can think of the whole computer systems like a human body that consist of cells of various types. They can be hardware or software. When they are software units, the smaller they are, the easier it is for them to self-heal, recuperate from failures, multiply or even get destroyed when that is needed. We call those small units microservices, and they can indeed have behaviours similar to those observed in a human body. The microservices-based system we are building can be made in a way that is has the ability to self-heal. That is not to say that self-healing we are about to explore is applicable only to microservices. It is not. However, self-healing can be applied to almost any type of the architecture but provides best results when combined with microservices.

During this workshop we’ll explore practices and tools required to set up fully autonomous self-healing systems capable of both reactive recuperation from failures and proactive predictions of steps that should be taken to prevent failures before they happen.

We’ll use tools like Docker, Docker Swarm, Docker Compose, Consul, Consul Template, Registrator and Jenkins to design and develop a system that is continuously deploying services packed as containers and perform actions that will recuperate it from failures and scale or de-scale depending on historical records.
