A. B. C. D. E.Explanation.
The answer to this question depends on various factors such as the size and complexity of the applications, the resource requirements of the instances, and the capabilities of the server hardware.
In general, containers are considered to be more lightweight and efficient than virtual machines as they share the host operating system kernel and require fewer resources. Therefore, hosting instances in containers can potentially allow for hosting the most instances on a server.
However, in some scenarios, using virtual machines may be more appropriate. For example, if the instances require different operating systems or if they have complex dependencies that are difficult to manage in a container environment.
Using virtual machines in containers (option D) is not a common approach and may not be practical in many cases. Microservices (option E) are an architectural approach that breaks down applications into small, independent components, but this does not necessarily have a direct impact on the number of instances that can be hosted on a server.
In conclusion, the most appropriate answer to this question is likely to be option C: using only containers. However, it is important to consider the specific requirements of the applications and the limitations of the server hardware before making a decision on the hosting approach.
