Milline on konteinerite kasutamise ja virtuaalmasinate kasutamise vahe rakenduste juurutamisel?

Containers and virtual machines (VMs) are technologies for application isolation and deployment, but they differ in architecture and resources.

Virtual Machines:

• Emulate a full operating system on top of a hypervisor.
• Each VM contains its own OS kernel, libraries, and applications.
• Are more resource-intensive (CPU, memory, disk).
• Provide strong isolation.

Containers:

• Use the host OS kernel, isolating processes at the namespace and cgroups level.
• Are lighter and start faster.
• Allow running multiple containers on a single host with lower overhead.
• Isolation is less strict than in VMs but sufficient for most applications.

Example: If you need to quickly deploy multiple instances of an application with minimal resources, using containers (e.g., Docker) is better. If full isolation and the ability to run different operating systems are required, prefer VMs.
