Virtual machines and Virtualisation: A Quick Introduction to Advanced Concepts
In our previous article, we only scratched the surface of the vast potential that exists in the dynamic world of virtualisation. Today, we embark on an interesting journey to discover more about the complex structure of cutting-edge virtualisation concepts.?
Exploring Advanced Features
Virtual machine (VM) tools offer a wide range of features to boost productivity, streamline operations, and strengthen resilience in case of disaster recovery.
Some features of VM tools that enable users to overcome the limitations of traditional computing, include:
Understanding Hypervisor Types
There are two types of hypervisors:
While both serve as the foundation for virtualised systems, their architectural variances result in unique functionality and use cases.?

Type 1 hypervisors, often known as bare-metal hypervisors, run directly on the actual hardware of a? system, eliminating the requirement for an underlying operating system. This architectural approach has several benefits, including improved performance, lower overhead, and higher security. By running directly on the hardware, Type 1 hypervisors have privileged access to system resources, allowing them to manage resources more effectively and provide stronger isolation between VMs. Examples of Type 1 hypervisors include VMware vSphere/ESXi, Microsoft Hyper-V, and KVM .
In contrast, Type 2 hypervisors, also known as hosted hypervisors, function on top of a standard operating system. This architectural approach adds another degree of abstraction because the hypervisor manages hardware resources in conjunction with the underlying operating system. While Type 2 hypervisors may offer simplicity of installation and maintenance, they often suffer more overhead and worse performance compared to their Type 1 counterparts. Examples of Type 2 hypervisors include VMware Workstation, Parallels Desktop, and Oracle VirtualBox.
By deconstructing the complexities of each hypervisor type, we arm ourselves with the information required to confidently traverse the virtualisation environment, making educated selections that correspond with our organisational goals and infrastructure requirements.
Virtualisation: Optimising Performance, Securing Environments, and Navigating Challenges
In order to make virtual environments scalable, you need to manage VMs. This includes mastering the technical details of CPU and memory allocation, disk management, resource monitoring, resolving hypervisor vulnerabilities, and establishing strong VM isolation mechanisms to protect against possible attacks. Furthermore, VM performance needs to be troubleshooted and optimised. By providing useful insights and techniques for fine-tuning virtual machine performance, detecting common difficulties, and applying efficient troubleshooting tactics, organisations can overcome barriers and keep their virtualised infrastructure running smoothly.
