This talk will explore the benefits of using serverless architecture in the context of Java applications. This allows startups like Cobrainer to focus on business logic, instead of dealing with infrastructure operations. Examples will cover the migration process of a monolithic application to event-driven cloud architectures, specifically how to make use of services such as AWS Lambda, Amazon Aurora Serverless and Amazon EventBridge. The talk will also cover cost-saving aspects of such migration and common pitfalls to look out for.
