OK, if you know anything about the cloud, you’re going to say the most popular cloud operating system is Linux. With the exception of Microsoft Azure with Windows Server 2008 and Windows Server 2012, the most popular client operating system family on clouds is indeed Linux. But, can you guess what seems to be the most popular guest Linux on clouds?

I couldn’t blame you, if — based on recent headlines such as “Linux worm Darlloz targets Intel architecture to mine digital currency” and “Botnet of thousands of Linux servers pumps Windows desktop malware onto web” — you thought Linux was as full of holes as Windows XP. If you take a closer look, you’ll find that Linux isn’t the problem. No, the real security hole lies with some of Linux’s administrators and users.

It’s not too surprising that members of the Linux Foundation’s OpenDaylight Project believe that the networking industry thinks open source is the future for software-defined networking (SDN). After all, OpenDaylight is an industry consortium of technology powers, such as Brocade, Cisco, and Microsoft, devoted to open-sourcing SDN and Network Functions Virtualization (NFV). The Project’s survey was conducted by a third party, Gigaom Research, which found no less than 95 percent of networking professionals want open-source SDN.

Linux is very secure. Google’s Linux-based Chrome OS, with its auto-updating and security sandboxing, is even more secure. But, neither is perfect. At Google’s own Pwnium hacking contest and HP Zero Day Initiative’s (ZDI) annual Pwn2Own hacking contest, three new sets of security problems were found in Chrome OS… and then immediately patched.

Without the Domain Name System (DNS), we’re all lost on the Internet. DNS provides the service that translates our human readable Web addresses such as google.com to their real, but mysterious Internet Protocol version 4 (IPv4) addresses, such as 8.8.8.8 or IPv6’s 2001:4860:4860::8888. The problem with this master yellow pages directory to the Internet is that DNS records themselves can be corrupted or your communications with the DNS servers interrupted by a man-in-the-middle (MiM) attack.
On March 16, the network security company BGPmon reported that Google’s Public DNS server, 8.8.8.8, was hijacked for Internet users in Brazil and Venezuela for 22 minutes. During this so-called MiM attack, anyone seeking a Web site, e-mail server, or the like was redirected to a site belonging to British Telecomm’s Latin America division. The assault seems to have been result of Border Gateway Protocol (BGP) hijacking.

While digging into the last OpenStack User Survey, I found that Ubuntu Linux was the most popular OpenStack operating system.
No matter if users had dozens, or thousands, of CPU cores in their cloud, most preferrred Ubuntu. It was followed by the Red Hat Enterprise Linux (RHEL) clone CentOS, which is now part of the Red Hat family, and then RHEL itself. At the end of the herd, was Windows, Debian, openSUSE and SUSE Linux Enterprise Server (SLES).
