The document discusses Wongnai.com, a restaurant review and social networking website for food lovers in Southeast Asia. It launched in 2010 and now has over 820,000 users and 120,000 restaurants. As Wongnai's user base and content grew rapidly, the company needed to scale its infrastructure to handle the increased traffic and data. Wongnai migrated its systems to Amazon Web Services to gain scalability, flexibility and cost savings. It now uses services like EC2, RDS, S3, CloudFront, EMR and others to power its website and mobile apps and continuously optimize for millions of users.
