One of the big news of the vSphere 8.0.3 (8.0 Update 3) version if the ability of live patch ESXi without reboot the host and without migrate the workloads!

With the new Live Patching capability in ESXi, customers can address critical bugs in the virtual machine execution environment  and apply patches to all components without reboot or VM evacuation.

Virtual machines are Fast-Suspend-Resumed (FSR) as part of the host remediation process, for this reason this new feature is not compatible with some specific cases (like VM protected by vSphere FT or VM with PCI passthough).

In the first release, a subset of DRS capabilities was using the new vCLS feature and starting with vCenter 7.0.1, VMware vSphere Distributed Resource Scheduler (vSphere DRS) cannot function if vSphere Cluster Services VMs are not present in each vSphere cluster.

VMware by Broadcom has just released vSphere 8.0 Update 3 (8.0.3).

CentOS Linux was a freely available, community-supported Linux distribution that was developed, distributed, and maintained by the CentOS Project community contributors. It was derived based from Red Hat Enterprise Linux sources and released in alignment with the Red Hat Enterprise Linux production release cycle. For this reason was a great alternative to Red Hat Enterprise Linux.

Note that CentOS Linux is not a Red Hat product and does not have Red Hat support.

But in 2020, The CentOS Project, in coordination with Red Hat, announced that it would shift full investment to CentOS Stream, the upstream development platform for upcoming Red Hat Enterprise Linux releases. That mean that will be no more alligned to the production version of Red Hat Enterprise.

Lot of storage, cloud and backup solutions are promising some kind of data immutability.

Of course, immutability is an important key capability, but it does not imply automatically that your solution is secure (or more secure).

It can give a false sense of security if not implemented properly. When misconfigured, it is possible to delete supposedly immutable data, for example, by manipulating time/date settings on the storage device to bypass retention enforcement mechanisms.

Diffent products are implementing a security model called “four-eyes principle“, also know as the two-person rule or also multi-user authorization (MUA).

In the backup and data protection are, for example, Veeam Backup & Replication (starting with v12) has the Four-Eyes Authorization feature to protect some crucial operations.

But what is the four-eyes (4-eyes) principle and how does it work? First to all is nothing related to software or security but instead a way to minimize the human errors and can be appliable also to non IT activities.
