Traditional VMs vs. Containerized VMs: A Detailed Comparison

Virtual Machines (VMs) and containerised VMs are two prominent technologies in the realm of virtualization and cloud computing. Both have their unique advantages and disadvantages, making them suitable for different use cases. This page will compare VMs and containerised VMs, highlighting their differences, advantages, and disadvantages.?

Virtual Machines (VMs)

Definition:

A VM is a software emulation of a physical computer. It runs an entire operating system and applications, providing complete isolation from other VMs on the same host.

Advantages:

• Isolation: VMs provide strong isolation as each VM runs its own OS, making them more secure and stable.
• Compatibility: VMs can run different operating systems on the same physical hardware, making them versatile for various applications.
• Resource Allocation: VMs can be allocated specific resources (CPU, memory, storage), ensuring predictable performance.

Disadvantages:

• Resource Intensive: VMs require significant resources as each VM includes a full OS, leading to higher overhead.
• Slower Boot Time: VMs take longer to start compared to containers due to the need to boot an entire OS.
• Less Portable: VMs are larger in size (typically gigabytes) and less portable compared to containers.

Containerised VMs

Definition:

Containers are lightweight, portable software packages that include everything needed to run an application, sharing the host OS kernel but isolated from other containers.

Advantages:

• Lightweight: Containers are more efficient as they share the host OS, reducing overhead and improving resource utilization.
• Fast Deployment: Containers can be started and stopped quickly, facilitating rapid development and deployment cycles.
• Portability: Containers are highly portable across different environments, making them ideal for microservices and cloud-native applications.

Disadvantages:

• Security: Containers offer less isolation compared to VMs, potentially leading to security vulnerabilities if not managed properly.
• Single OS Dependency: Containers share the host OS, limiting the ability to run different operating systems simultaneously.
• Complexity in Orchestration: Managing and orchestrating large numbers of containers can be complex and may require additional tools like Kubernetes.
