In today's digital landscape, building applications that can handle varying workloads, respond to user demands, and recover from failures is crucial. The traditional approach of provisioning and managing servers can be resource-intensive, inflexible, and susceptible to scalability issues. This presentation explores the transformative potential of AWS serverless services, which offer a compelling alternative for building scalable, resilient, and reactive architectures. Attendees will gain insights into the core principles and benefits of serverless computing, including automatic scaling, pay-per-use pricing, and reduced operational overhead. The presentation will delve into key AWS serverless services such as AWS Lambda, Amazon API Gateway, and Amazon EventBridge. Real-world use cases and best practices will be discussed, illustrating how these services can be seamlessly integrated to create event-driven, microservices-based architectures that respond dynamically to changing conditions.
