Era M\u00edo is a Uruguayan omnichannel retailer operating in the secondhand market\u2014one of the fastest-growing segments in global retail, valued at US$393 billion and expanding three times faster than traditional retail. With brick-and-mortar stores in Uruguay and an e-commerce platform (eramio.com.uy), Era M\u00edo allows its customers to both sell used items and purchase curated secondhand products\u2014from clothing to accessories and more. <\/p>\n\n
Despite being an SME, Era M\u00edo\u2019s operational complexity rivals that of much larger retailers. Every item in inventory is unique\u2014the company does not use SKUs. Each item must be tracked individually from consignment receipt through pricing, multi-store visibility, omnichannel synchronization, supplier settlements with commission calculations, and regulatory-compliant electronic invoicing. <\/p>\n\n
Era M\u00edo’s original technology stack was built on .NET and SQL Server, running on limited on-premises infrastructure. As the business grew\u2014adding new branches and launching an e-commerce channel\u2014the legacy platform became a bottleneck:<\/p>\n\n
BigCheese partnered with Era M\u00edo to design, build, and operate a comprehensive cloud-native retail platform on AWS\u2014migrating from .NET\/SQL Server to a containerized Java architecture that supports the entire lifecycle of the secondhand retail business.<\/p>\n\n
The core ERP system was re-architected from .NET\/SQL Server to a Java web application running on Amazon ECS with Fargate<\/strong>, eliminating the need for server management and providing automatic scaling. The migration from SQL Server to Amazon RDS MySQL<\/strong> eliminated licensing costs entirely\u2014a critical savings for an SME. <\/p>\n\n Each branch operates as an independent deployment with its own application cluster and configuration, sharing a centralized database with logically separate schemas. This provides complete operational isolation\u2014a deployment issue at one branch does not affect the other\u2014while optimizing database costs. <\/p>\n\n A two-way integration via REST API connects the ERP system to the e-commerce platform in real time:<\/p>\n\n This two-tier synchronization model effectively eliminates the double-selling of unique items\u2014an existential risk for any secondhand retailer operating across multiple channels.<\/p>\n\n AWS Batch<\/strong>, with dedicated computing environments for each branch, handles scheduled operational tasks: supplier settlement calculations (with commission prorating by item for bulk sales), inventory synchronizations, and report generation\u2014replacing manual processes that previously consumed significant staff time.<\/p>\n\n Amazon QuickSight<\/strong> connects to a dedicated read replica of the database, ensuring that analytical queries do not impact transactional performance. This provides Era M\u00edo\u2019s management team with self-service dashboards offering visibility into sales performance, inventory metrics, supplier analytics, and distribution data. For the first time, the business can make data-driven decisions across all its channels. <\/p>\n\n Automated deployments via AWS CodePipeline<\/strong> ensure that both branches receive updates simultaneously, with built-in manual approval gates and the ability to roll back automatically in less than 5 minutes.<\/p>\n\n The story of Era M\u00edo shows that cloud-native modernization on AWS isn’t just for large companies. By migrating from a legacy .NET\/SQL Server stack to a containerized, fully managed architecture, a growing SMB retailer was able to:<\/p>\n\n As the global resale market continues to accelerate and consumers increasingly expect seamless omnichannel experiences, Era M\u00edo\u2019s platform on AWS positions the company to scale its circular economy model across Latin America.<\/p>\n","protected":false},"excerpt":{"rendered":" Transforming Retail: From On-Premises .NET to AWS-Native Era M\u00edo is a Uruguayan omnichannel retailer operating in the secondhand market\u2014one of the fastest-growing segments in global retail, valued at US$393 billion and expanding three times faster than traditional retail.
