The cloud-native technology where applications rely on managed services that abstract away the need to manage, patch, and secure infrastructure and virtual machines is Serverless.

Here's a step-by-step explanation:

1. Understanding the Options:

   • Serverless: This technology allows developers to build and run applications without managing the underlying infrastructure. The cloud provider automatically handles the infrastructure, scaling, patching, and security.
   • Thin VMs: These are lightweight virtual machines that still require some level of management, including patching and securing the infrastructure.
   • Containers: Containers package applications and their dependencies, but they still require orchestration and management of the underlying infrastructure.
   • CaaS (Containers as a Service): This is a managed service for running containers, but it still involves some level of infrastructure management.

2. Key Characteristics of Serverless:

   • No Infrastructure Management: Developers do not need to manage servers or virtual machines.
   • Automatic Scaling: The cloud provider automatically scales the application based on demand.
   • Pay-per-Use: Billing is based on the actual usage of the application, not on pre-allocated resources.
   • Managed Security and Patching: The cloud provider handles security updates and patches for the underlying infrastructure.

3. Conclusion:

   • Among the given options, Serverless is the technology that abstracts away the need to manage, patch, and secure infrastructure and virtual machines. This allows developers to focus solely on writing code and deploying applications without worrying about the underlying infrastructure.

Therefore, the correct answer is Serverless.
