    Challenge\u00a0<\/strong><\/p>\n

    EELIS was built as a monolithic, workstation-based\u00a0application \u2014 the\u00a0legacy\u00a0architecture limited scalability, was painful to use in the field, and\u00a0didn’t\u00a0integrate with modern digital workflows.<\/span>\u00a0<\/span><\/p>\n

    Solution\u00a0<\/strong><\/p>\n

      \n
    • Microservices\u00a0migration.\u00a0<\/span><\/b>Complete\u00a0platform\u00a0rebuild on a\u00a0microservices\u00a0architecture for modularity and scale.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
        \n
      • PostgreSQL\u00a0geo-databases.\u00a0<\/span><\/b>Backed by interactive map applications and automated CI\/CD deployment pipelines.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
          \n
        • Mobile field tools.\u00a0<\/span><\/b>Restructured for seamless data exchange with external registries and support for mobile use in the field.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
            \n
          • AI-ready data foundation.\u00a0<\/span><\/b>Reworked data models enable pattern recognition, decision support, and geospatial analytics.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
              \n
            • Open data publishing.\u00a0<\/span><\/b>Opens the door to training ML models for environmental\u00a0research and forecasting.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n<\/div>\r\n\r\n\n\n\n
              \"\"<\/figure>\n\n\n
              \r\n

              Result\u00a0<\/strong><\/p>\n

                \n
              • An intelligent, scalable, data-rich platform for\u00a0nature\u00a0management across Estonia.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
                  \n
                • Specialists have meaningfully better tools for fieldwork and daily operations.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
                    \n
                  • Manual data flows\u00a0largely\u00a0replaced by automated processes.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n
                      \n
                    • EELIS is now a strategic decision-support system, not just\u00a0a static\u00a0registry.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

                       <\/p>\n

                      Key takeaway\u00a0<\/strong><\/p>\n

                      Environmental and scientific registries gain disproportionately from\u00a0microservices \u2014 the real win is unlocking AI and automation that the old architecture made impossible.<\/span>\u00a0<\/span><\/p>\n<\/div>\r\n\r\n\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"featured_media":1275,"template":"","case_category":[9,33,10,7,15],"industry":[12],"class_list":["post-1027","case","type-case","status-publish","has-post-thumbnail","hentry","case_category-ai","case_category-backend","case_category-java","case_category-public","case_category-ux","industry-public"],"acf":[],"yoast_head":"\nA
