A compliance-first sa-east-1 build for an online gaming platform — 170ms to 30ms latency and a clean LGPD audit.
Tech4Bet wanted to capture the Brazilian gaming market but was serving local players from US and EU regions at 150–200ms latency. LGPD required Brazilian player data to stay in country with auditable controls, and the existing infrastructure had patchy multi-AZ coverage, no tested DR, and a console-built history that made replicating it elsewhere slow and error-prone.
sa-east-1 built from the ground up with LGPD as a foundational constraint: dedicated S3 and Multi-AZ RDS in-region, KMS keys scoped locally, IAM policies enforcing geographic access boundaries, and CloudTrail recording every data-access event. CloudFront with latency- and geo-based Route 53 routing serves Brazilian users from local edges with WAF protection, and the entire region is codified as a reusable Terraform regional blueprint.
Average Brazilian latency fell from 170ms to under 30ms, lifting session duration 35% and cutting bounce rates 40% in the first month. The deployment passed LGPD review with zero findings, three quarterly DR exercises completed cleanly with sub-45-second database failover, and the platform absorbed a 4× promotional traffic spike without manual intervention.
Under the hood
“Remāngu understood the regulatory landscape and technical requirements for operating in Brazil. They delivered a solution that met every compliance requirement without compromising the user experience our players expect.”
