Siemens Healthineers transitioned from manual processes to a modern SaaS, underscoring the importance of Site Reliability Engineering (SRE) foundations by focusing on crucial Service Level Indicators (SLIs) like availability and leveraging observability data for continuous improvement. The Harness Platform supports this journey by managing Service Level Objectives (SLOs), conducting chaos experiments, and validating deployments to enhance system reliability. In an episode of ShipTalk, Dr. Vlad Ukis, Head of R&D for Siemens Healthineers, discusses this transition and highlights the critical role of selecting key SLIs and creating baselines for measuring improvements. By doing so, Siemens Healthineers aims to improve the reliability of their medical devices and healthcare technology, which are vital in maintaining lives and quality of care in the healthcare industry. The Harness Platform offers robust features to support resilience goals through organizing SLOs, experimenting, and using observability data to ensure successful deployments.
