Static Binding vs Ephemeral Binding: Understanding the Network Bindings in VMware vSphere Distributed Switch

Networking is a key component of enterprise virtualization, and as data centers grow, it is imperative to manage network resources effectively and flexibly. VMware’s vSphere Distributed Switch (VDS) is a potent tool that allows for centralized management of networking configuration across ESXi hosts, and one of its key features is its management of network port bindings. There are two main types of bindings that are available with VDS: static and ephemeral. Virtualization administrators that want to optimize their environments must grasp the distinctions, benefits, and trade-offs between static and ephemeral port binding.

A Deep Dive into VMware vSphere vMotion Application Notification: Keeping Applications in the Loop

Ensuring application availability and performance during infrastructure maintenance is essential in the ever changing virtualization landscape. VMware’s flagship product, vMotion, allows virtual machines (VMs) to be moved between physical hosts without interruption. How about the programmes that are executing in such virtual machines? Can they be told that the relocation is coming and given enough time to be ready?

Now for vMotion Application Notification, a revolutionary feature that debuted with vSphere 8. By giving apps the ability to actively participate in the vMotion process, this feature improves resiliency and reduces migration interruptions. Let’s investigate the advantages, settings, and best practices of this cutting-edge technology in more detail.

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.

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.

Guest Operating System Upgrade or New Virtual Machine?

Virtual Machine needs guest operating system (OS) to operates same as physical machine. Operating system is a system software and has life cycle same as other software. But what should we do about updating and upgrading guest operating systems in virtual environments. Guest Operating System Life-Cycle Most implemented services don’t need to any new features on operating system, so we should choose guest operating system with long term support. Both Windows and Linux (Some distributions) offering different of channels. You can choose a path that more stable or choose a path for have new features. Update vs Upgrade When you need to newest technologies and features on the latest major version of operating system, you have to do Upgrade. But when you are applying regular patches on operation system, you are doing Update. Keep Update Guest Operating System Operating systems’ vendors releasing patches during operating system life-cycle. Apply patches (Security or others) to keep guest operating system secure and stable as well as your services and business. Even installing service packs or upgrading to a minor version of current guest operating system is an update process and there is no limitation to do it. When We Should Upgrade Guest Operating...

What’s SDS (Software-Defined Storage) – Part 2 (Ceph)

Whether you want to provide Ceph Object Storage and/or Ceph Block Device services to Cloud Platforms, deploy a Ceph Filesystem or use Ceph for another purpose, all Ceph Storage Cluster deployments begin with setting up each Ceph Node, your network, and the Ceph Storage Cluster. A Ceph Storage Cluster requires at least one Ceph Monitor, Ceph Manager, and Ceph OSD (Object Storage Daemon). The Ceph Metadata Server is also required when running Ceph Filesystem clients.
