Security threats in a virtual environment

Security is typically a hot-topic due also to several regulations and compliant rules and laws. But more important, a security breach can have huge collateral effects, also if no data has been stoled, or compromised. But, for example, a “simple” DoS attack that makes a service not available can have a bad effect on the reputation of a B2C company. This post will try to give an idea of some possible security threads in a virtual environment based on VMware vSphere (but several concepts are quite general also for other virtualization platforms) and some possible approaches to minimize the effect or prevent the attacks.

Why upgrade to VMware vSphere 6.5 (or why not)

VMware vSphere 6.5 is the latest version of the enterprise server virtual platform from VMware, but the new beta it’s already there for testers. Actually the next version it’s (in the beta). If you are building a new infrastructure from scratch the latest stable version is probably the best choices (for most cases); but what about if you have an old environment and you plan to upgrade it?

VMware vCenter Server Appliance Homelab tips

Many IT administrators or virtualization guys run their homelabs at home. It is a good way to learn new technologies, be able to break things in a lab to get stronger skills. It is sometimes a challenge, to squeeze as much RAM as possible from it. The main challenge is always a memory utilization. VMware VMs are getting memory hungry all the time and they are not “optimized” for Homelab use, but rather for production environments. Yes, it is the main purpose of those VMs after all.
