Alex Bramley continuous his conversation with Sven Johann. They start with what external and internal dependencies do with your availability requirements and how you calculate availability if you have a microservices dependency tree. They look into how you can introduce SLOs to your organisation. After that, they switch to measure user happiness with your monitoring system, measurement windows and how to report those results.

Alex Bramley talks to Sven Johann about the basics of service level objectives. They begin with terminologies (SLI, SLO, SLA, Error Budget), look at costs of outages and discuss what reliability has to do with customer happiness. They continue with having 100% reliability is the wrong target and what’s possibly the right target. Alex then explains how to get started with collecting data about your system’s behaviour. They close the first part of this series by looking into latency SLIs.

In this episode, Markus Völter talks with Stefan Tilkov about language engineering and its connection to domain-driven design. Picking up from their past interactions in various different podcasts, the two agree and disagree fundamentally in equal parts, on topics such as the usefulness of DSLs, the costs and benefits of domain experts writing code, and the tradeoffs of various architectural approaches.
