Virtual servers: No safer than any other kind

August 13th, 2014 · Comments Off

Once upon a time, we used to think in terms of one hardware server equals one server operating system. Then, along came KVM, Hyper-V, VMware, and all the rest of the virtual machine (VM) hypervisors and more recently Docker with its containers. Now the idea of a single server operating system on a solo box is downright quaint.

Don’t think, however, that just because your servers are virtual instead of physical that they are somehow safer from security threats. They’re not.

As Symantec stated in its new report, Threats to virtual environments, “Virtual machine hosting servers are not any [more] secure than any other type of server. They are just as vulnerable to malware or targeted attacks.”

Internet hiccups today? You’re not alone. Here’s why

August 12th, 2014 · Comments Off

If you found your Internet speed has been pathetic today and some sites wouldn’t load at all, you’re not alone.

Many tier-one Internet service providers (ISPs), and in turn, the last mile ISPs they support, experienced technical problems that resulted in bad service throughout the US and some parts of Canada.

According to postings in the North American Network Operators Group (NANOG) mailing list, the professional association for Internet engineering and architecture, there have been “major problems with multiple ISPs since around 4-5 AM EST.” 

According to NANOG, and complaints tracker DownDetector, many Internet providers — including Level 3, AT&T, Cogent, Sprint, Verizon, and others — have suffered from serious performance problems at various times on Tuesday.

And they won’t be the last.

Nadella’s challenge: Saving Microsoft

August 11th, 2014 · Comments Off

In my recent debate with Ed Bott over Microsoft’s future, the public bought Ed’s arguments that Microsoft will have a bright, shining future with Satya Nadella as CEO. The judge though gave me the win because he agreed that “Nadella’s challenges outweigh his support and time window won out. After all, there are a lot of fix-it jobs to do after Steve Ballmer.”
