Service Observability

When business systems adopt microservices architecture and migrate to the cloud, we face many challenges, especially how to view the status of each individual service of the application, quickly locate and resolve online issues, and monitor the call relationships between services. In the cloud-native world, observability is one of the categories used to address these challenges. This chapter will introduce the definition and application of service observability, the difference and relation between observability and monitoring, the current state of the observability community, and our team’s practice on observability adoption.
