Serverless and Application Integration

Serverless computing has transformed the landscape of cloud-based infrastructure, providing users with scalable and highly available methods of running code without the need for direct server management. This chapter explores the core principles and services that underpin the serverless paradigm, with a focus on equipping you with the knowledge and skills required to design and implement efficient, cost-effective, and resilient serverless applications.

You will begin with an overview of serverless computing, where you will explore its key advantages, such as automatic scaling, pay-per-use pricing, and reduced operational overhead. This contextual foundation sets the stage for a detailed examination of AWS Lambda. You will gain a comprehensive understanding of the Lambda function architecture, including the concepts of event-driven invocation, concurrency management, and execution environment reuse. Having established the fundamentals of standalone...
