KubeVirt: The Next-Gen Virtualization Solution for Kubernetes – Run Containers and VMs Side-by-Side

KubeVirt is a Kubernetes-native virtualization solution that allows users to run virtual machines (VMs) and containers side-by-side on the same platform. Kubernetes has become the standard for managing containerized applications in the ever-changing field of cloud computing and containerization. Containers have revolutionized the packaging, distribution, and deployment of applications, providing unmatched flexibility and scalability. However, certain tasks cannot be confined to containers alone, requiring the use of virtual machines (VMs). To address this, the KubeVirt project has been created to seamlessly integrate VMs with containers, allowing Kubernetes to effectively handle both technologies.

Should You Use VMware Fault Tolerance All the Time?

VMware Fault Tolerance (VMware FT) is one of vSphere clustering features that can protect services with zero downtime but not useful for any services or any virtual machine.

This post is not about VMware Fault Tolerance capabilities and I’ll reviewing use cases. At end of this post, you’ll find why this feature is not suitable for each service or environment. Also find that when you should use it and when you should not use that.

CIS Benchmarks – How to Apply on Operating Systems?

Stupid security guys! They only know concepts and has no technical knowledge about their technical field. They just read some documentations. But most important steps of having security is applying configuration and reviewing current configuration. Also, they have no idea that what are they doing on servers and client. CIS benchmarks are reference for hardening most popular operating systems, but you cannot apply the desired configurations in large scale of servers or clients without using some tools.

Iran Daylight Saving on March 2023

The government of Iran has announced that daylight savings will not be observed from March 2023. But apparently, this issue has not been properly coordinated with international institutions. So this was cause of many issues on public services in Iran. We did some updates and configuration changes before 22nd March 2022 and I want to share the story with you.

Virtual Machine Identification (VM-ID) in Fibre Channel: A Comprehensive Overview

Virtual Machine Identification (VMID or VM-ID) is a technology for tracking virtual machine I/O between virtual machine and SAN target. VM-ID can be used by hypervisor and FC switch to trace generated I/O by specific VM. As result, we can optimize whole SAN area for VI workload and non-VI workloads would be achieved.

Kata Containers, Container with VM Isolation

Kata Containers offers method of container deployment with more security. Security is one biggest challenge about containers and containers has lower level of security compared to virtual machines. Because virtual machines are isolated from each other, but containers can’t provide isolation same as virtual machines.
