Containers share the host machine's kernel rather than simulating complete hardware, so startup speed can reach the millisecond level, with resource overhead far lower than traditional virtual machines.

VerifiedContainers share the host machine's kernel, while virtual machines emulate complete hardware.79% similarUnverifiedVirtual machines rely on a hypervisor to emulate a complete computer, with the guest having its own kernel, forming a stronger security boundary than containers against the host, but with significantly higher memory and startup overhead.79% similarUnverifiedContainer sandboxes start faster and have lower resource overhead compared to traditional virtual machine isolation, making them suitable for Agent workloads that require frequent creation and destruction.79% similarVerifiedTraditional full virtual machines (such as complete VMware or KVM instances) offer strong isolation but are slow to start and consume significant resources.79% similarUnverifiedLinux containers are essentially a set of isolated and constrained ordinary processes, not virtual machines.74% similar
