Because anyone who processes, classifies, and makes millions of documents searchable every day needs more than just a solid database \u2013 they need a platform that can keep pace with the demands of AI, scalability, and speed. Since 2023, EVANA has relied on MongoDB Atlas as its core database infrastructure. The result: a more stable, faster, and more precise platform for our customers \u2013 and a foundation that grows with our ambitions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-top is-layout-flex wp-container-core-columns-is-layout-1022ce0c wp-block-columns-is-layout-flex\" style=\"margin-top:var(--wp--preset--spacing--70);margin-bottom:var(--wp--preset--spacing--70);padding-right:var(--wp--preset--spacing--60);padding-left:var(--wp--preset--spacing--60)\">\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\" style=\"padding-right:var(--wp--preset--spacing--50);padding-left:var(--wp--preset--spacing--50)\">\n<h3 class=\"wp-block-heading has-text-align-center\">Challenge<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Tech sprawl, inconsistent data storage, and the limitations of relational databases slowed down the speed, stability, and scalability of the EVANA platform.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\" style=\"padding-right:var(--wp--preset--spacing--50);padding-left:var(--wp--preset--spacing--50)\">\n<h3 class=\"wp-block-heading has-text-align-center\">Decision<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">EVANA migrated to MongoDB Atlas as a single source of truth in 2023 \u2013 for operational simplicity, flexibility and maximum developer efficiency.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\" style=\"padding-right:var(--wp--preset--spacing--50);padding-left:var(--wp--preset--spacing--50)\">\n<h3 class=\"wp-block-heading has-text-align-center\">Result<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Capacity for nearly one million files per day, 95 % accuracy over 38 million scanned pages \u2013 and a platform that delivers up to eight new releases daily.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\">From Tech Sprawl to Single Source of Truth<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"has-text-align-left wp-block-paragraph\">In the first few years after its founding, EVANA&#039;s infrastructure grew organically \u2013 and with it, its complexity. PostgreSQL, Azure SQL, Elasticsearch, and MongoDB coexisted, data was replicated multiple times, and teams worked with different database logics. The result: rising costs, instability, and a platform that could no longer keep pace with the growing demands of AI processing. The decision to adopt MongoDB Atlas was the turning point: a unified, flexible platform that processes both structured and unstructured data \u2013 and is specifically designed for the requirements of modern AI applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-f2cd8118 wp-block-columns-is-layout-flex\" style=\"padding-top:var(--wp--preset--spacing--50);padding-bottom:var(--wp--preset--spacing--50)\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h3 class=\"wp-block-heading\">Three factors that tipped the scales<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Operational simplicity, flexibility, and developer efficiency \u2013 these were the decisive criteria in the evaluation. MongoDB Atlas minimizes DevOps effort, enables rapid iteration, and supports all requirements from simple CRUD operations to vectorization and complex pipelines with a unified query language. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a growing AI company like EVANA, this is not a nice-to-have \u2013 it is a basic requirement.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-3e41869c wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link has-luminous-vivid-orange-background-color has-background has-text-align-center wp-element-button\" href=\"https:\/\/demo.evana.ai\">Get to know EVANA now<\/a><\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image aligncenter size-large is-resized has-custom-border\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"745\" src=\"https:\/\/evana.ai\/wp-content\/uploads\/2026\/04\/evana-hero-1024x745.jpg\" alt=\"EVANA mit MongoDB Infrastruktur\" class=\"wp-image-2726\" style=\"border-top-left-radius:53px;border-top-right-radius:53px;border-bottom-left-radius:53px;border-bottom-right-radius:53px;box-shadow:var(--wp--preset--shadow--natural);aspect-ratio:1.21474435196195;object-fit:cover;width:508px;height:auto\" srcset=\"https:\/\/evana.ai\/wp-content\/uploads\/2026\/04\/evana-hero-1024x745.jpg 1024w, https:\/\/evana.ai\/wp-content\/uploads\/2026\/04\/evana-hero-300x218.jpg 300w, https:\/\/evana.ai\/wp-content\/uploads\/2026\/04\/evana-hero-768x559.jpg 768w, https:\/\/evana.ai\/wp-content\/uploads\/2026\/04\/evana-hero-18x12.jpg 18w, https:\/\/evana.ai\/wp-content\/uploads\/2026\/04\/evana-hero.jpg 1100w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center\"><strong>Precision and speed \u2013 combined in one system<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">EVANA now processes over 30,000 documents per hour using MongoDB Atlas.
