Containers vs VMs (virtual machines): What are the differences Virtual machines provide an abstracted version of the entire hardware of a physical machine, including the CPU, memory, and storage. Containers are portable instances of software with its dependencies that run on a physical or virtual machine.Virtualization lets you run multiple operating systems on the same physical server, whereas containerization enables you to deploy multiple applications or microservices on the same operating system without any hardware abstraction.Containers and VMs combined

VMs are a great place to run Docker hosts. Whether it may be vSphere VM, Hyper-V VM, or AWS EC2 instance, all of them are equally capable of hosting a docker container server. Containers and VMs sync perfectly as container-based services can interact with VM-based services.

What is the disadvantage of container over VM : Disadvantages of containers

Security: The shared Linux kernel provides far more vulnerability to attacks than a hypervisor in a VM. If an attacker succeeds in accessing the kernel from a container, all containers attached to it are usually affected. VMs, therefore, tend to isolate applications better than containers.

Is Kubernetes a VM

Kubernetes is Cloud Native, VMs are not

Kubernetes is designed to be cloud-native, meaning that it can run on any public cloud platform. This makes it easy to deploy and manage applications across different cloud providers, without having to worry about compatibility issues.

Is a Docker container a VM : A VM lets you run a virtual machine on any hardware. Docker lets you run an application on any operating system. It uses isolated user-space instances known as containers. Docker containers have their own file system, dependency structure, processes, and network capabilities.

While a hypervisor abstracts away hardware for the virtual machines so they can run an operating system, a container engine abstracts away an operating system so containers can run applications.

Amazon Elastic Compute Cloud (EC2) is the Amazon Web Service you use to create and run virtual machines in the cloud (we call these virtual machines 'instances').

Is Docker like a VM

A VM lets you run a virtual machine on any hardware. Docker lets you run an application on any operating system. It uses isolated user-space instances known as containers.If you need Docker too, run a virtual machine with LXD and run Docker containers in that virtual machine. You could run Docker in an LXC container too, but that is not trivial and requires additional parameters and privileges. What is a container “understood as a VM” Its either virtual machine or a container.Advantages of Docker Containers

Docker containers are process-isolated and don't require a hardware hypervisor. This means Docker containers are much smaller and require far fewer resources than a VM. Docker is fast.

In contrast, running within a single OS while using containers in cloud computing allows defects to damage the entire system. Because of the complete isolation provided by VMs, security is improved, and vulnerabilities are more difficult to exploit.

Is a pod a VM : A vSphere Pod is a VM with a small footprint that runs one or more Linux containers. Each vSphere Pod is sized precisely for the workload that it accommodates and has explicit resource reservations for that workload. It allocates the exact amount of storage, memory, and CPU resources required for the workload to run.

Why move from VM to containers

Containers are much lighter than VMs since they don't contain the operating system, and therefore require considerably fewer compute and memory resources. Containers provide greater density of workloads across your clusters, fine-grained resource allocations, and overall lower infrastructure costs.

Kubernetes and virtual machines are two different platforms that are suited for different use cases. Kubernetes is designed specifically for deploying and managing containerized applications, while virtual machines are designed for running entire operating systems and applications.In contrast, running within a single OS while using containers in cloud computing allows defects to damage the entire system. Because of the complete isolation provided by VMs, security is improved, and vulnerabilities are more difficult to exploit.
