We often hear that security and privacy concerns are the main inhibitors to cloud adoption. But what are the true threats? Is the cloud really more dangerous than your on-site data center? I would say that virtualization and cloud computing aren’t inherently more dangerous, but they have unique infrastructure that must be addressed when creating…
Read MoreIn my last blog post, I discussed some of the benefits of agentless security for virtual and private cloud servers. Today at VMworld, Harish Agastya, Director of Data Center Security at Trend Micro, conducted a presentation on Agentless Security for VMware Environments (listed on the Trend Micro VMworld page). Trend Micro released agentless antivirus in…
Read MoreThere’s a lot of talk about cloud computing and cloud security this week as many people are attending VMworld in Las Vegas (follow Trend Micro at VMworld).

Quite a lot of companies were affected and you can find the list here. The Internet was flooded with articles speculating what went wrong,…
Read MoreDo you know what cloudbursting is? It is a concept where when you run out of your computing resources in your internal data center, you “burst” the additional workload to an external cloud on an on-demand basis.
Read MoreIs Virtualization stupid? It forces guest VMs sharing a host to do the same things over and over, without sharing. It takes up countless hours of otherwise useful – and expensive – server time.
Read MoreEveryone is familiar with the traditional nursery rhyme, “London Bridge is Falling Down.” However, few know that it traces its roots back to a factual wonder of the medieval world.
