Zalando Deploys LLMs To Automate Postmortems

Zalando adopted large language models to analyze thousands of archived postmortems on April 5, 2026, targeting datastore technologies such as Postgres, DynamoDB, ElastiCache, S3 and Elasticsearch. The company built a multi-stage LLM pipeline to reduce hallucination and context loss, automating pattern detection and thematic clustering. The approach yields faster, repeatable SRE insights and informs infrastructure investment and reliability decisions.
