With the assistance of Cloud, we will provision a VM in seconds and create it able to use terribly apace and that we pay solely what we use. varied Cloud suppliers additionally supports the containers like AWS. however the employment of each depends on use case to use case .

2)Scalability - Scalability is a major role in designing the infrastructure of any software. Both Virtual machine and container are scalable in but depends on the use they both are choosen one. Containers are more scalable then VM's.

3)Portability - Portability is basically software to run on different platform easily. Containers provides the portability feature , while Virtual machine doent support it.

4) Resource Utilization - In past years we tend to use information centres during which we've massive servers which regularly use large areas and continually underutilized. The utilization of VMs create deploy of of these systems on one massive machine and make totally utilised. Then containers get image that are terribly price effective and simple to use.
