Virtual Machines vs Containers
PowerCert Animated Videos・7 minutes read
Engineers developed virtual machines to allow multiple applications to run on a single server, addressing underutilized capacity and increased costs. Containers, such as Docker, offer a lightweight and fast alternative to VMs by containing only an application with necessary files and dependencies.
Insights
- Engineers introduced virtual machines (VMs) to address the inefficiency of one application per server, enabling multiple applications to run on a single server, reducing costs and maximizing server capacity.
- Containers, exemplified by Docker, offer a more lightweight and efficient alternative to VMs, containing only necessary application files and dependencies, thereby enhancing speed, portability, and resource utilization compared to traditional VMs.

What are virtual machines in business operations?
Virtual machines (VMs) are software that allows multiple applications to run on a single server by simulating hardware and software. They help in maximizing server capacity and reducing costs by running multiple applications on a single server.
How do virtual machines manage multiple applications?
Virtual machines utilize a hypervisor to manage multiple virtual machines, each with its own operating system and applications. This allows for efficient use of server resources and eliminates the need for separate physical servers for each application.
What are the drawbacks of virtual machines?
Virtual machines have drawbacks such as consuming significant disk space, RAM, and CPU power. Additionally, they require licenses for each operating system used, which can add to the overall cost of implementing virtual machines in business operations.
How do containers differ from virtual machines?
Containers, like Docker, differ from virtual machines by containing only an application with all necessary files and dependencies. They are lightweight, fast, and portable, making them a more efficient option for running applications compared to traditional virtual machines.
What problem do virtual machines solve in business operations?
Virtual machines solve the issue of underutilized server capacity and increased costs in traditional business operations. By allowing multiple applications to run on a single server, virtual machines help in maximizing server resources and reducing the need for additional physical servers.
