Ocado is the world's largest dedicated online grocery retailer and continuously seeks to improve the efficiency, reliability and resilience of their warehouse control systems. Unusual Systems was engaged to upgrade the legacy systems at Ocado's Hatfield site.
Situational, Java and C# problems were investigated, analysed and resolved. Legacy services were updated to Java/Spring REST micro-services delivered through gitlab pipelines in Docker containers to kubernetes farms. Performance data was transformed and loaded into Google's BigQuery analytic platform via a Kinesis pipeline.
