Netflix decided in 2008 that its new business model would have been the complete consumption of public cloud, specifically AWS. It took 8 years to the leader in Video Streaming to complete the migration of its services into AWS, and now Netflix doesn’t run any significant workload in its own premises.
Latest news about telecommunication companies and their struggles against giant cloud service providers show how the war for the public cloud is at its peak, and we are starting to see the first victims.
Snapshot commit operations have always been a problem, especially for large and really active virtual machines. But vSphere 6 has introduced some changes that are probably going to make commits a problem of the past!
In my previous post, I talked about BTRFS, a modern and exciting filesystem for Linux. In this new post, I’m going to give you a quick walkthrough on what you can do with it.
Switching to a new filesystem is never a task that is done with a light heart. We have our own trusted good old filesytem, that has maybe limits in features and performance, but has never let us down. New filesystems are available, and they promise wonderful things. But as much as we are fascinated by them, the big Q “Should I trust it?” comes to mind when we just start thinking about moving to a new filesystem.

In 2012 I wrote a blog post that became really popular: Installing VMware tools on Centos 6 via yum. Few years forward, and today the preferred tools are the open sourced ones available natively in many linux package managers. So, some may think to switch from one version to the other one for their existing virtual machines. That’s what I’ve done in some of my virtual machines, and here is the process.
CentOS is known for not using the latest versions of the Linux kernel. If you need up-to-date versions, you need to configure the OS to use different repositories.
I started to blog when I was already working on virtualization technologies, but before this I was a security consultant, and I still hold my CISSP certification. So, for once I’m writing something about security more than virtualization, because this news about SSL totally deserves an article. TLS is hard… let’s keep SSL for a […]
