VMware vSAN clusters are typically aggregates of several ESXi hosts. Local disks with VM data are divided into groups there. It’s preferable that each disk’s load variance doesn’t reach 30%. If it does, there are two options: Automatic and Proactive rebalancing. Each of them has its own pros and cons; you decide which to choose.
Every admin knows that however perfect an environment may be, it’s bound to encounter certain problems along the way. One of the most confusing issues for a VMware vSphere admin is VMware ESXi hosts in vCenter Server being nor responding since there can be too many different reasons. Luckily, you have a chance now to find out the most common ones and means to deal with them!
Just as VMware’s Project Pacific implies, the plans for the further submergence into the world of containerized applications for vSphere clusters intends to deepen. VMware Tanzu Mission Control is to allow admins to manage Kubernetes clusters regardless of their residential environment. The tool is rumored to become the single base of all K8s cluster operations.
Security issues, unfortunately, remain a priority even today, because, obviously, there is no such thing as too much protection. In the case of the custom domains on your apps, the same rules apply. Luckily, there is a new security feature for Azure App Service released. App Service Managed Certificates will help you to secure your domains on Windows and Linux apps!
Virtualization was always about making the most out of less. But corporations fighting over customers divided them into incompatible camps. Recently, though, the winds in the industry have changed. VMware just launched an application mobility platform that migrates and re-balances on-premises vSphere and non-vSphere (Hyper-V and KVM) infrastructures to public clouds based on VMware vCloud!
Keeping your storage up to date is a necessary action one takes to ensure the efficiency of overall infrastructure performance. However, manual handling of such matters as testing storage or setting the workload pattern can be rather tedious to conduct. Or at least it was until the IOBlazer utility kicked in!
It is not enough to build a functioning hyperconverged infrastructure because any IT environment needs to be constantly in check. Testing cluster performance is a necessity that requires the most serious approach. Hot news for VMware vSAN users is that they do not have to spend all that time and effort anymore since this efficient utility allows automating testing process carried out with such benchmark tools as VDbench or Fio.
VMware is not a newbie in IT security sport. Their work presents an impressive portfolio, with such solutions as AppDefense, vRealize Network Insight, and NSX-T/NSX-V. In March 2019, VMware introduced the first Service-defined Firewall, their endgame. Take a closer look under the hood to find out how it came to be a real game changer in the world of virtualized environment security.
VMware Horizon View is a VMware product that aims to improve the infrastructure of the virtual desktop as well as support bring your own device (BYOD) programs. Most administrators back up virtual desktops, but very few pay enough attention to backing up the Horizon View configurations. At the same time, a backup of a VMware Horizon View environment configuration is a critical part of the work of your virtual desktop infrastructure that guarantees its integrity. Moreover, if you any have problems with a large View Manager configuration that can last from several hours to several days, your Horizon View configurations need a safe harbor badly. So, don’t wait for a second!
If you are a VMware vSphere administrator who wants to solve the problem of a low network throughput, Network I/O Control (NIOC) is exactly what you need! It’s a traffic-specific vSphere Distributed Switch (vDS) mechanism of network bandwidth regulation that was firstly introduced in vSphere 4.1 in 2010. NIOC appeared when 10G networking was increasingly prevalent and became a real breakthrough. With this mechanism, you can ensure high network throughput and go with fewer network adapters in ESXi hosts. That sounds pretty good, doesn’t it?
