 How do Technologies such a virtual machine and containers help improve operational efficiency?

1. by eliminating the need for cloud data centre altogether

2. by spreading energy consumption across multiple locations

3. by allowing multiple applications to run a single server

4. by reducing the consumer demand to Cloud Computing services ​

Both virtual machines and containers allow multiple applications to run on a single physical server, which improves operational efficiency by maximizing resource utilization. This reduces the need for additional physical servers, which saves on hardware costs, space, and power consumption.

The second option ("by spreading energy consumption across multiple locations") is not correct, as virtual machines and containers do not directly relate to spreading energy consumption across multiple locations.

Virtual machines are a type of software that allows multiple operating systems to run on a single physical server. Each virtual machine is isolated from the others, which makes it possible to run different operating systems and applications on the same physical hardware.

Containers are a type of lightweight virtualization that allows multiple applications to run on a single operating system kernel. Containers share the underlying operating system, but each container is isolated from the others, which makes it possible to run multiple applications on the same physical hardware without the overhead of virtualization.

Both virtual machines and containers can help improve operational efficiency by reducing the number of physical servers needed to run multiple applications. This reduces hardware and energy costs, and also simplifies management and maintenance of the infrastructure.
