☁️ Free practice test question from: Cloud Native Architecture (KCNA)

Containers are lightweight, share the host system's OS, and are ideal for applications that need to be deployed rapidly and scaled efficiently. They are particularly well-suited for microservices architectures, where individual services can be developed, deployed, and scaled independently.

Virtual Machines (VMs), on the other hand, include a full operating system and provide stronger isolation, making them more suitable for scenarios that require full OS environments or high levels of security and isolation.

****

A) Running a legacy monolithic application: These applications often have complex dependencies and require a specific OS environment, making VMs a better fit.  

C) Hosting multiple virtualized desktops: Each desktop requires a full OS instance and user-specific configurations, which is better handled by VMs.

D) Running a resource-intensive database workload: While containers can run databases, the direct hardware access and strong isolation provided by VMs are often preferred for performance and security reasons, especially for very demanding database workloads.
