Invenco, a logistics SaaS company specializing in e-commerce order fulfillment, transitioned from Aurora Serverless v2 to Neon to address challenges with managing serverless traffic and high costs. With AWS Lambda at its core, Invenco's serverless infrastructure faced issues with Aurora, particularly during traffic spikes, leading to dropped connections and insufficient scaling capabilities. Neon, utilizing a connection pooler based on pgBouncer, offered a seamless out-of-the-box solution that handled concurrent requests efficiently, reducing database costs by 80% and improving performance. The migration to Neon allowed Invenco to consolidate non-production services into a single project, simplify data management through branching, and utilize logical replication for minimal downtime during the transition. This setup provided Invenco with a scalable and cost-effective architecture, optimizing operations across its microservices-based framework and supporting its growth in the competitive e-commerce logistics sector.
