Summary

In this chapter, we delved into the world of serverless computing, a paradigm shift that brings both opportunities and challenges to cloud architecture. We kicked things off by introducing the concept of serverless, its benefits and challenges, and how it compares to traditional microservices. We then discussed the security considerations that are unique to serverless architectures, covering a wide range of topics from responsibility domains and zero-trust architecture to data encryption and compliance. We also explored event-driven security mechanisms, diving into event sources, schema validation, and data encryption. This chapter concluded with a deep dive into securing Lambda functions, discussing code integrity, environment variables, runtime protection, and monitoring, among other key security aspects.

As we move on to the next chapter, we will explore the complex yet crucial topic of multi-tenancy in shared environments, focusing on secure design patterns and techniques...
