Episode 43 — Containers vs VMs and When to Use Each
Containers and virtual machines both isolate workloads but differ in architecture and operational efficiency. This episode explains those differences, helping learners distinguish their advantages for exam and practical purposes. Virtual machines virtualize hardware, providing complete operating systems with dedicated resources. Containers virtualize at the application layer, sharing the host OS kernel, which makes them faster to start and easier to scale. The Google Cloud Digital Leader exam frequently includes questions comparing these technologies in the context of modernization strategies. Choosing correctly depends on factors such as deployment speed, governance, and resource optimization.
We look at scenarios where containers offer agility—like continuous integration and microservices—while VMs remain ideal for legacy workloads needing full system control. Google Kubernetes Engine and Cloud Run simplify container orchestration and scaling, while Compute Engine continues to support traditional applications. Understanding these options allows leaders to recommend hybrid approaches that balance innovation and stability. Exam readiness comes from recognizing that containers serve cloud-native agility, whereas VMs provide transitional or specialized reliability.
