Now, it only takes two engineers (at most) to operate and maintain the TiDB solution.&nbsp;&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hybrid transactional and analytical capabilities&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">TiDB Cloud has a two-in-one architecture, or an HTAP architecture. Transactional and analytical workloads do not have to be separately processed by different databases anymore. One TiDB system can handle both workloads at the same time.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Much lower costs&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">TiDB Cloud replaced most of KNN3\u2019s storage components, which cut their cost significantly. In addition, engineers now maintain fewer databases, so the maintenance cost is lower too.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Seamless, horizontal, transparent, and automatic scalability&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">TiDB Cloud can scale out elastically and easily based on changes in real-time read and write traffic. This perfectly fits KNN3\u2019s business needs because the Web3 industry is booming. When their business expands, they don\u2019t have to redesign their storage architecture.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cloud-native design for future integration&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">TiDB is a cloud-native database, which makes it simple and easy to integrate with the ecosystem. This paves the way for future expansion and cooperation with various partners.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n<div style=\"background-color: #172d72;border-width: 2px;border-color: #abb8c3\" class=\"ub_call_to_action wp-block-ub-call-to-action-block\" id=\"ub_call_to_action_384052ec-10af-411c-a7c5-1885f9b57bb5\">\n\t\t\t<div class=\"ub_call_to_action_headline\">\n\t\t\t\t<p class=\"ub_call_to_action_headline_text\" style=\"font-size: 32px; color: #ffffff; text-align: center; \">Try TiDB Cloud Free Now!<\/p>\n\t\t\t<\/div>\n\t\t\t<div class=\"ub_call_to_action_content\">\n\t\t\t\t<p class=\"ub_cta_content_text\" style=\"font-size: 16px; color: #ffffff; text-align: center; \">Get the power of a cloud-native, distributed SQL database built for real-time <br>analytics in a fully managed service.<\/p>\n\t\t\t<\/div>\n\t\t\t<div class=\"ub_call_to_action_button\">\n\t\t\t\t<a href=\"https:\/\/tidbcloud.com\/free-trial\" target=\"_self\" rel=\"noopener noreferrer\" class=\"ub_cta_button\" style=\"background-color: #0ca6f2; width: 203px; \">\n\t\t\t\t\t<p class=\"ub_cta_button_text\" style=\"color: #ffffff; font-size: 21px; \">Sign Me Up<\/p>\n\t\t\t\t<\/a>\n\t\t\t<\/div>\n\t\t<\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Looking_to_the_future\"><\/span>Looking to the future<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">By using TiDB Cloud, KNN3 simplified its storage architecture, lowered its storage costs, and optimized its service performance.
