What are Containers and Virtual Machines?
In this video, we dive into the key differences between Docker containers and Virtual Machines (VMs).
Definitions:
Virtual Machines (VMs): Emulated instances that run full guest operating systems on a hypervisor, offering strong security isolation.
Docker Containers: Lightweight, portable environments that package applications and share the host OS kernel, providing process-level isolation.
Key Differences:
Architecture: VMs run on a hypervisor; containers use a container runtime.
Resource Utilization: VMs are resource-heavy; containers are efficient and fast to start.
Isolation: VMs offer strong isolation; containers use namespaces and cgroups.
Portability: Containers are highly portable; VMs may require configuration for migration.
Use Cases: VMs are ideal for legacy apps; Docker suits modern DevOps and microservices.
