A combination of Serverless tools such as Athena, StepFunctions, Lambda, or Glue can get the job done in many projects. However, some customers prefer to rely on Open-Source projects and tools to access more talent in the job market and be less reliant on a single cloud provider. Today, we’ll share a story of a modernization project that we did for a customer in the online marketing industry.
