How to Build Scalable Cloud DICOM-WEB Services Learn how to build distributed DICOM-WEB services using open-source projects. Overall Architecture Apache Kafka as message queue. RedPanda can be used as alternative during development. Apache Doris as data warehouse. Provides storage for DicomStateMeta, DicomImageMeta, and WadoAccessLog, offering query and statistical analysis. PostgreSQL as database. Provides data storage and indexing functions. Stores only patient, study, and series level metadata to fully leverage ACID properties of relational databases. Can be scaled later with Citus. Redis as cache. Provides data caching functionality. Nginx as reverse proxy server. Provides load balancing, static files, and TLS termination. Files received by the storage service are first stored locally, then sent to the message queue via Kafka. ...
