What advantage does Kubernetes offer with regard to serverless infrastructure?

1. Requires VM access

2. Integrates with AWS Lambda

3. Operates without direct access to VMs

4. Only runs on physical servers

The correct answer is: Operates without direct access to VMs

Kubernetes provides a significant advantage in operating without the need for direct access to virtual machines (VMs). This characteristic is particularly beneficial for implementing serverless architectures, as it abstracts the underlying infrastructure complexities. By managing containers rather than individual servers or VMs, Kubernetes allows developers to focus on deploying applications and services without worrying about the specifics of VM management or provisioning. This is a crucial feature of serverless infrastructure, where the focus is on executing code in response to events without the typical overhead of server management. With Kubernetes, you can dynamically allocate and release resources as needed, enabling a more efficient and cost-effective approach to scaling applications in response to demand. The other options suggest limitations or specific integrations that do not reflect the core strengths of Kubernetes in the context of serverless design. For instance, requiring VM access directly opposes the serverless concept, while only running on physical servers contradicts the model used by many cloud-native applications. Integrating with AWS Lambda is a possible scenario but does not encompass the full capability of Kubernetes to operate independently of VM access.
