Merge has introduced a single tenant architecture to cater to enterprise-level users seeking enhanced security and compliance with industry standards. This approach, likened to renting a private Airbnb, offers increased flexibility and custom specifications for data management. The company faced challenges in syncing customer-specific and operational data across isolated systems, which they addressed using Amazon Web Services' Simple Notification Service (SNS) and Simple Queue Service (SQS) to ensure reliable and scalable data propagation. This development is part of Merge's broader strategy to provide a robust integration platform, and the company is actively hiring to continue solving such engineering challenges.
