Educational Episodes: Hyperconverged Infrastructure (HCI)

Nowadays it’s quite trendy to have penetration testing as a starting point for cybersecurity. Even though penetration testing is a good practice, it’s very limited and focused on one application/product and should therefore not be used as an entry point for cybersecurity.

Everybody knows that access errors are the most irritating ones in any computer-related activity. They become even more confusing if the traditional means to get behind it won’t work. Say, you are trying to connect your VM to a domain, and you get this infamous “access denied” message? Don’t worry that this will bother you.

VMware snapshots are important part of vSphere infrastructure. Using snapshots is very flexible way of being able to go back in time and revert changes. VMware snapshots are used by admins, developers and other IT team members who are not all VMware specialists. As such it might be a good idea to learn some good practices about snapshots and this technology, to get the most out of it.

There isn’t really much to say about Terraform and ways it can help you manage your environment that hasn’t been already said. However, highlighting its features does not limit to deploying resources in Azure or storing passwords for security measures. Time to find out how your working process can reach more efficiency!

Windows Admin Center (WAC) is a locally-deployed, browser-based management tool that provides you with the full control over your Windows Server environment. The nice thing is, it does not push you to Azure or any other cloud, so it works for you even if you do not feel that enthusiastic about public cloud.

Some time ago, I published articles on setting up a home lab using a PC running ESXi and Workstation. We all know that nested virtualization is not an ESXi-only feature; Microsoft Hyper-V also enables us to run VMs inside its VMs. Microsoft’s implementation of this technology is a bit different, but it exists. And, considering that VMware and Microsoft have been competing for a long time, it’s interesting to see what each has to offer for this type of virtualization. In this post, I examine how easy it is to configure a nested virtualization layer inside Hyper-V and vSphere VMs and discuss peculiarities of this process in both environments.

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!

You have probably already covered the basics of Django installation on Ubuntu Server 18.04 LTS. This framework now is ready for the ride, but, as you know, there’s always room for improvement. If you have a little interest in using default SQLite database option, then it’s time to opt for better!

Once engineers came up with the way to virtualize graphics processing units (GPUs), the new era started for machine learning, gaming, modeling, and whatever else IOPS-hungry: all these applications can now go cloud! In this article, I’d like to take a closer look at why GPU virtualization is so promising, who pioneers this tech, and how VMware managed to cover the gap between the virtual and bare-metal GPUs.
