Episode 40 — VMs, Containers, Microservices, Serverless

The evolution from virtual machines to containers, microservices, and serverless computing represents the progression toward greater efficiency and automation. This episode explains each abstraction and why it matters for the Google Cloud Digital Leader exam. Virtual machines, or VMs, provide isolated environments for full system control. Containers package applications with dependencies for lightweight portability. Microservices divide applications into independent components that scale and deploy separately. Serverless computing removes infrastructure management entirely, letting developers focus on logic and outcomes. Understanding this continuum helps learners reason about architecture modernization and operational impact.We compare scenarios across this progression: a finance firm maintaining compliance through VMs, a software company accelerating deployment through containers, and a startup embracing serverless to reduce operational overhead. Each model has trade-offs in control, scalability, and cost. Exam questions may test which abstraction suits a given workload or business constraint. The ability to articulate these differences in plain language is a key leadership skill and demonstrates exam readiness.
