The 4 Biggest Questions About Docker from VMworld 2016

Simply incredible. We spent last week at VMworld speaking with thousands of enterprise security, infrastructure and virtualization pros. It was humbling to witness all of the curiosity and excitement around Docker at the show, and how Docker clearly made a strong impression on the attendees.

This curiosity around Docker and its use within enterprise environments is the reason why i’m writing this blog. We noticed that there were many of the same questions that arose, and we figured we should share them with you, as you start your journey towards adopting Docker containers and VMs.

Here are the most commonly asked questions from the conference.

1. What is Docker? Or even a container? Is it a lightweight VM? Can I use it with vSphere? What value do they provide?

Containers are really about applications, not servers. That’s why they aren’t VMs. @docker #VMWorld #TFD

A Docker container is a standard unit in which application code, binaries and libraries can be packaged and isolated. The Docker Engine is the runtime installed on your infrastructure of choice and is what executes commands to build and deploy containers. Many containers can be connected together to form a Continue reading

Today’s supercomputers will get blown away by these systems

The Department of Energy says the $40 million it is investing in nearly two dozen multi-year projects will result in exascale computing systems that perform calculations on data 50 to 100 times faster than today's most powerful supercomputers.The DoE Exascale Computing Project says such high-performance computing systems can make at least a billion billion calculations per second, and will be used to process data for applications such as energy security, economic security, scientific discovery, healthcare and climate/environmental science. The U.S. is shooting to attain such powerful systems by the mid-2020s and China is aiming for 2020.To read this article in full or to leave a comment, please click here

UK police listened in to 9 percent more calls last year

The U.K. government has published a report on the staggering scale of surveillance in the country last year.The report, compiled by the Interception of Communications Commissioner's Office (IOCCO), covers the surveillance activities of the U.K.'s three main intelligence agencies (MI5, the Secret Intelligence Service, and GCHQ, the Government Communications Headquarters), the tax authority, and a number of police forces.It shows that warrants for the interception of communications rose 9 percent and that authorities continue to collect communications metadata -- information about who called or connected to whom, when, how often -- with abandon. To read this article in full or to leave a comment, please click here

Microsoft’s all-in-one Surface PCs could debut next month

A few months back I reported on rumors of new Surface-branded all-in-one PCs from Microsoft that could target both other all-in-ones as well as Apple's languishing iMac line. Now new information says they are coming soon.Citing her usual deep bench of sources, Mary Jo Foley of ZDNet says there will be a hardware launch event in late October, one year after a New York City event at which Microsoft unveiled the Surface Book, Surface Pro 4, Lumia 950 and 950 XL.To read this article in full or to leave a comment, please click here

The time Cisco’s Rob Soderbery hooped it up vs. NBA’s Kyrie Irving

Reading about Cisco exec Rob Soderbery's departure from the company, I couldn't help thinking back to the first time I came across the enterprise products muckety-muck: Back at Interop 2013 in Las Vegas, where Soderbery took on Cleveland Cavalier star Kyrie Irving in a basketball shooting contest in the name of IoT marketing.The Stanford- and Caltech-educated Soderbery was pumping up Cisco's vision for software-defined networking as well as the internet of things, and it is IoT where the Irving cameo came in.  Cisco was getting into the game of a much more connected pro sports world, where sensors in everything from basketball shoes to basketballs help teams better measure player and team performance and improve the fan experience.To read this article in full or to leave a comment, please click here

JBAS011469 Error in Junos Space

Just went onto a customer’s Junos Space/Security Director installation to discover that their SRX5800 was showing as ‘out of sync’.    I tried to do a ‘Resynchronize with Network’ from the Device Operations menu, but this failed with the following error:

Error while reading config from device: <devicename> javax.persistence. TransactionRequiredException: JBAS011469: Transaction is required to perform this operation (either use a transaction of extended persistence context)

JBAS011469 error in Space 15.2

Unfortunately (like most Space-related errors) there’s nothing about this in Juniper’s knowledgebase – the only hit I found on a Google search was a similar error, but with a different cause that had been fixed.   So I thought I’d put this here in case it helps anyone.  

The solution in the end was to update the DMI schema for the device. The SRX5800 had been upgraded from 12.1R3.5 to 12.3X48-D30.7 but the schema within Space had not.  I downloaded the appropriate schema, and now the device re-syncs just fine.

Xen Project patches serious virtual machine escape flaws

The Xen Project has fixed four vulnerabilities in its widely used virtualization software, two of which could allow malicious virtual machine administrators to take over host servers.Flaws that break the isolation layer between virtual machines are the most serious kind for a hypervisor like Xen, which allows users to run multiple VMs on the same underlying hardware in a secure manner.The Xen hypervisor is widely used by cloud computing providers and virtual private server hosting companies like Linode, which had to reboot some of its servers over the past few days to apply the new patches.To read this article in full or to leave a comment, please click here

This USB stick will fry your unsecured computer

A Hong Kong-based technology manufacturer, USBKill.com, has taken data security to the "Mission Impossible" extreme by creating a USB stick that uses an electrical discharge to fry an unauthorized computer into which it's plugged."When the USB Kill stick is plugged in, it rapidly charges its capacitors from the USB power supply, and then discharges -- all in the matter of seconds," the company said in a news release.

US lawmakers make last-ditch bid to block internet governance transfer

Republican lawmakers are making a last-ditch bid to thwart the proposed transfer by the U.S. of internet governance to a multistakeholder body, by calling on the government to reconsider its plans to put the transition into effect by month end.Raising fears that control of the internet could pass to authoritarian regimes, the legislators wrote in a letter Thursday to Attorney General Loretta E. Lynch and Secretary of Commerce Penny Pritzker that there were unresolved issues, such as the ability to ensure that the Internet Corporation for Assigned Names and Numbers would in fact follow its own bylaws after the transfer.To read this article in full or to leave a comment, please click here

University of California’s outsourcing is wrong, says U.S. lawmaker

A decision by the University of California to lay off IT employees and send their jobs overseas is under fire from U.S. Rep. Zoe Lofgren (D-Calif) and the IEEE-USA.The university recently informed about 80 IT workers at its San Francisco campus, including contract employees and vendor contractors, that it hired India-based HCL, under a $50 million contract, to manage infrastructure and networking-related services.The university employees will remain on the job until the end of February, but before then they are expecting to train their foreign replacements. The number of affected employees may expand. The university's IT services agreement with HCL can be leveraged by any institution in the 10-campus system.To read this article in full or to leave a comment, please click here

OSPF Areas and Summarization: Theory and Reality

While most readers, commenters, and Twitterati agreed with my take on the uselessness of OSPF areas and inter-area summarization in 21st century, a few of them pointed out that in practice, the theory and practice are not the same. Unfortunately, most of those counterexamples failed due to broken implementations or vendor “optimizations”.
