1.
| A virtualization technique where each VM has an individual operating system.
| A virtualization technique where all containers share a host operating system.
|
2.
| Virtual machines are isolated at the hardware level
| Each container is isolated at the operating system level.
|
3.
| Virtual machines take time to create
| Containers are CREATED fast
|
4.
| Increased management overhead
| Decreased management overhead as only one host operating system needs to be cared for.
|
5.
| Takes minutes to boot up
| Boots up in seconds
|
6.
| Full isolation of VM’s thus providing high security
| Decreased security compared to VM’s
|
7.
| VM’s are huge as it has the overhead of the separate OS
| Lightweight as multiple containers share the same host operating system.
|
8.
| VM’s are mostly application-centric as making it service-centric is not a cost viable option.
| Containers can be designed to be service-centric i.e a container for every microservice. Hence it is HIGHLY customizable for the performance of that particular microservices. Service-centric is the capability to CONFIGURE a single service to run in a single container.
|
9.
| Higher Cost
| Less costly compared to VM’s
|
10.
| More effort required to make VM’s versionable.
| Easily Versionable
|
11.
| The MARKETPLACE in VM’s are segmented and not well known as Docker Hub
| Availability of a central, trusted marketplace where we can pull the IMAGES for the containers
