Posted by Vladimir Yamkovoy on February 26, 2018

When in the distant 2001 the VMware ESXi hypervisor appeared on the market, a virtual revolution started that began the end of the era of personal computers with the programs installed on them. This event opened a new era in the development of computers and software – client-server technologies and cloud computing technologies.

Building a Cluster based on VMware (part I)
Posted by Veniamin Kireev on January 29, 2018

To build a cluster, VMware uses from 2x to 32x ESXi servers that are managed using vCenter. To build a cluster, you also need a shared store. It can be implemented with VMware vSAN or with storage support providing access via Fiber Channel, iSCSI or NFS. The storage stores the virtual machine files that are available to all the cluster hosts at the same time. It is due to the overall storage and independence of the virtual machine from the physical platform that rapid migration/recovery of virtual machines is achieved.

AWS Still Dominating Cloud Market, but Azure, Google and Alibaba are Growing Faster
Posted by Augusto Alvarez on January 24, 2018

No one should be surprised at this point if we mention that Amazon Web Services (AWS) is the main cloud provider in the market, they were and still are one of the main innovators and precursors of cloud services. It’s not going to be a surprise either if we tell you the Microsoft Azure is in second place and growing, but it may surprise you how much Google Cloud is actually growing and that Alibaba Cloud was the second largest growth year-over-year.

Azure with New Apps Features: Adaptive Applications Controls and App Service Diagnostics
Posted by Augusto Alvarez on January 10, 2018

Microsoft is continuously releasing new features and options available in their public Azure version, the initial state is usually the “preview” of this feature, which after a period and final touches transforms into General Availability (GA). Within the last couple of weeks, Microsoft released two new features in these two different stages: Adaptive Applications Controls as a public preview and Azure App Service Diagnostics as general availability. These new features come with great benefits for organizations relying on Azure to host critical applications.

Install updates in WIM files to accelerate OS deployment
Posted by Romain Serre on December 27, 2017

When I deployed Bare-Metal servers, I always lose time because of updates. In part of my job, I deploy a lot of physical servers, especially for Microsoft hyperconverged solution. When I install this kind of solution, I have to implement between three to sixteen servers at the same time. The cumulative update installation in Windows Server takes almost 30 minutes. If the servers are not installed at the same time, you can lose a lot of time. This is worst when you install physical servers with a tool like MDT and PXE. You have to copy 1GB in each server and then wait to install it.

To save time, now when I’m deploying physical servers, I update the install.wim file. In this way, the OS is installed with latest updates. In this topic, we’ll see how to update images in WIM files.
