I tried this, this and some similar solutions, but I couln't g. Tengo la siguiente clase : @Entity() @Table(name = user ) public class UserBean extends BaseEntity implements Serializable private static final long serialVersionUID = 1L; @Id @GeneratedValue( Definitely Docker. Using containerization gives you max flexibility. In your first approach, you jar is dependent on Java. Whenever you create new VM, you need to install fix set of software to support you application. Benefits in second approach, First, everything is going to be in single container. When I have created a ASP.NET Web API application, I have checked to enable Docker for the project, not really knowing what that does. Now, I cannot start my application, becasue when I run it, I h. From what I understand about Docker, it's a tool used for virtual environments. In their lingo, its called containerization. This is more or less what Python's virtualenv does. However, you can use virtualenv in Docker. So, is it a virtual environment inside a virtual environment? Docker is not a replacement for IIS - it can run an application like IIS within a container (I assume - not sure how this is going to work on Windows). Docker is more like a replacement for a VM - the biggest difference between a VM and a Docker container is that the Docker container is MUCH lighter than a full VM. The usual claim that you see is that you can run many more Docker containers on. The description of the tag dockerfile says “A Dockerfile is a file containing instructions to build a Docker image” ⸺ Yes, it was right, but nowadays Dockerfiles are not specific to Docker.

Scaling from 1 to 50 Docker machines once you have already created the initial image is blindingly fast in comparison to the step by step approach Ansible takes, and this is most obvious during a rolling deploy of many machines in smaller groups. Each has its drawbacks in either ability or speed.
