Case Study: South American Bank accelerates cloud migration with LocalStack

South American Bank accelerates cloud migration for 2,000 engineers with LocalStack

The customer, a major South American bank, faced the challenge of scaling its developer workforce from hundreds to thousands while preparing for a full cloud migration. Their core platform team struggled with flaky CI pipelines and inconsistent local development environments within a massive monorepo. To support this growth and standardize microservice development, they needed a formalized solution for local AWS emulation, which led them to the vendor, LocalStack.

LocalStack provided a standardized platform for local AWS service emulation, which was integrated into the bank's existing Docker-based workflows and CI pipelines. The solution enabled teams to emulate services like DynamoDB, SQS, and Lambda locally. This resulted in improved developer velocity through faster feedback cycles, increased standardization across engineering teams, and enhanced quality and reliability by allowing for full-stack testing in isolated environments, thereby supporting the organization's broader cloud migration goals.
