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.

Veeam Backup and Replication – How to Choose Best Transport Mode for vSphere Proxy?

I’m sure that most IT administrators are familiar with Veeam’s products and specially, Veeam Backup and Replication (Veeam BR). This product is one of popular backup and replication suite for physical and virtual environments. Veeam Backup and Replication offers three transport modes and we’ll review the transport modes and condition of their selection in this post.

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.

Optimizing Data Protection: Unleashing the Power of Database Backup Best Practices in Virtualization Platforms

Virtualization platforms such as VMware vSphere or Linux KVM supporting large scale of virtual machines now. Even, virtualization platforms can host monster virtual machines as database server. At this post, we’ll review database backup solutions in virtualization platforms about advantages and disadvantages.

Network Latency: Best Tools for Measuring

Enterprise businesses such as banking business using latency sensitive applications. Most of application delay issues are related to network infrastructure. Also most of application server are Linux servers. How can we measure network latency on Linux?

Fibre Channel Trunking (Aggregation): Better Performance, Higher Bandwidth (>1 Tb/s)

We are all knowing LACP on ethernet network but Fibre Channel and SAN network providing multipathing I/O by using logical and physical paths as single device on operating system and also using path selecting policies for using I/O paths optimized. But if server using 16Gb/s FC HBA, so there is no bandwidth aggregation. Server can generate bandwidth for each port up to maximum speed of port and also path selecting has performance impact of server when large paths are presented to server. Months before, I was thinking about FC port aggregation and did many searches but I didn’t find anything until now.

MicroVM and Firecracker: Discover Advantages and Disadvantages

During virtualization revolution, physical servers replaced with virtual machines to run multiple different workloads on a single server hardware but virtual machines were still large and needs some resources to run as isolated servers. Virtual machines needs to have their own operating system and applications. Also they needs to manage and configure separately. MicroVM or Micro Virtual Machine offering benefits of two different technologies and Firecracker will help you to implementing MicroVM.
