In 2023, an Amazon Prime Video team published a blog post about how they saved costs and increased scalability by migrating away from a serverless architecture. Does this mean serverless is a failure if even Amazon is moving away from it? To address this question, we will explore how a serverless architecture is effectively used at OTTO's marketplace to select customers for discounts and benefits. We'll also discuss why the Amazon Prime Video team made the right decision by migrating away from serverless, highlighting the different needs and contexts of each use case. By the end, you'll be able to decide for yourself when a serverless architecture is the right choice and when it's better to opt for more traditional technologies.
