Technology Short Take #79

Welcome to Technology Short Take #79! There’s lots of interesting links for you this time around.

Networking

  • I was sure I had mentioned Skydive before, but apparently not (a grep of all my blog posts found nothing), so let me rectify that first. Skydive is (in the project’s own words) an “open source real-time network topology and protocols analyzer.” The project’s GitHub repository is here, and documentation for Skydive is here.
  • OK, now that I’ve mentioned Skydive, I can talk about this article that provides an example of functional SDN testing with Terraform and Skydive. Terraform is used to turn up OpenStack infrastructure, and Skydive (via connections into Neutron and OpenContrail, in this example) is used to validate SDN functionality.
  • Tony Sangha took PowerNSX (a set of PowerShell cmdlets for interacting with NSX) and created a tool to help document the NSX Distributed Firewall configuration. This tool exports the DFW configuration and then converts it into Excel format, and is available on GitHub. (What’s that? You haven’t heard of PowerNSX before? See here.)

For Big Banks, Regulation is the Mother of GPU Invention

There is something to be said for being at the right place at the right time.

While there were plenty of folks who were in the exact wrong spot when the financial crisis hit in 2007-2008, some technologies were uniquely well timed to meet the unexpected demands of a new era.

In the aftermath of the crash, major investment banks and financial institutions had a tough task ahead to keep up with the wave of regulations instituted to keep them straight. This has some serious procedural impacts, and also came with some heady new demands on compute infrastructure. Post-regulation, investment …

Docker Reaches The Enterprise Milestone

In the server virtualization era, there were a couple of virtual machine formats and hypervisors to match them, and despite the desire for a common VM format, the virtual server stacks got siloed into ESXi, KVM, Xen, and Hyper-V stacks with some spicing of PowerVM, Solaris containers and LDOMs, and VM/ESA partitions sprinkled on.

With containers, the consensus has been largely to support the Docker format that was inspired by the foundational Linux container work done by Google, and Docker, the company, was the early and enthusiastic proponent of its way of the Docker way of doing containers.

Now, Docker …

Microsoft starts selling 6 more years of Windows Server support

Microsoft yesterday started selling extended support for its Windows Server software, letting corporate customers add up to six years to the lifespan of Windows Server 2008 and later, and SQL Server 2008 and later.The company had announced this "Premium Assurance" in December, saying then that the extended support would be available for purchase this month.[ Further reading: SharePoint 2013 cheat sheet ] Under Premium Assurance, only vulnerabilities graded as "Critical" and "Important" will be patched. The extended support costs between 5% and 12% of the current licensing cost for each year of coverage, depending on when a customer commits. The sooner a plan is bought, the lower the price.To read this article in full or to leave a comment, please click here

Classic smartphone brands get a spring in their step at MWC (+video)

BARCELONA -- Venerable smartphone brands Motorola, Nokia and BlackBerry got new life at Mobile World Congress 2017, but that was primarily due to the influence of Chinese and Finnish manufacturers that have licensed the names.One new Android smartphone, the BlackBerry KEYone, was launched by TCL Communication, based in Huizhou, China. The phone has both a touchscreen and a physical keyboard, with 52 keys that can be used as shortcuts to find apps and functions. It goes on sale in April for $549.HMD Global of Espoo, Finland, launched three budget Android phones under the Nokia brand — the Nokia 3, 5 and 6, starting at $147 with screens ranging from 5 inches to 5.5 inches in size. A 2000 classic handset was revised — the Nokia 3310 — but with a slimmer size and a color screen.To read this article in full or to leave a comment, please click here

Hottest iPad & Surface alternatives from Mobile World Congress 2017

While the traditional tablet market has had a tough go of it lately, some industry watchers do see growth ahead particularly in the 2-in-1 detachables sector, and the batch of new devices shown at Mobile World Congress in Barcelona this week could play a big role in any such revival.While most of the new smartphones demoed at MWC were of the Android variety, tablet makers gave Windows some love as well with possible Microsoft Surface alternatives. (Apple, as usual, didn’t display at MWC, but is said to have new iPads in the works.)To read this article in full or to leave a comment, please click here

Worth Reading: The data deletion landscape

Delete is a word built into the vocabulary of users from the beginning of personal computing. When commanded to “del,” an operating system appeared to erase a file completely. However, right from the start, a users’ commonsense understanding of the command to “delete” differed from companies’ practices; rather than erasing a file, “delete” meant “put in the recycle bin.” “Deleted” files were not really gone but rather out of sight, available to be recovered if necessary. The rise of cloud computing, where files live remotely from their owners’ devices and are frequently accessible from multiple devices, has further muddied the concept of deletion by saving all of a user’s files in an ambiguous location until called upon. While this change may seem trivial, it represents a larger truth about our digital files: they are almost never really “deleted.” —CDT

AWS says a typo caused the massive S3 failure this week

Everyone makes mistakes. But working at Amazon Web Services means an incorrectly entered input can lead to a massive outage that cripples popular websites and services. That's apparently what happened earlier this week, when the AWS Simple Storage Service (S3) in the provider's Northern Virginia region experienced an 11-hour system failure.Other Amazon services in the US-EAST-1 region that rely on S3, like Elastic Block Store, Lambda, and the new instance launch for the Elastic Compute Cloud infrastructure-as-a-service offering were all impacted by the outage.To read this article in full or to leave a comment, please click here

Slack bug paved the way for a hack that can steal user access

One bug in Slack, the popular work chat application, was enough for a security researcher to design a hack that could trick users into handing over access to their accounts.Bug bounty hunter Frans Rosen noticed he could steal Slack access tokens to user accounts due to a flaw in the way the application communicates data in an internet browser.“Slack missed an important step when using a technology called postMessage,” Rosen said on Wednesday in an email.  PostMessage is a kind of command that can let separate browser windows communicate with each other. In Slack, it’s used whenever the chat application opens a new window to enable a voice call.To read this article in full or to leave a comment, please click here

Free decryption tools now available for Dharma ransomware

Computer users who have been affected by the Dharma ransomware and have held onto their encrypted files can now restore them for free. Researchers have created decryption tools for this ransomware strain after someone recently leaked the decryption keys.Dharma first appeared in November and is based on an older ransomware program known as Crysis. It's easy to recognize files affected by it because they will have the extension: .[email_address].dharma, where the email address is the one used by the attacker as a point of contact.On Wednesday, a user named gektar published a link to a Pastebin post on the BleepingComputer.com technical support forum. The post, he claimed, contained the decryption keys for all Dharma variants.To read this article in full or to leave a comment, please click here

Microsoft, Stanford Researchers Tweak Cloud Economics Framework

Cloud computing makes a lot of sense for a rapidly growing number of larger enterprises and other organizations, and for any number of reasons. The increased application flexibility and agility engendered by creating a pool of shared infrastructure resources, the scalability and the cost efficiencies, are all key drivers in an era of ever-embiggening data.

With public and hybrid cloud environments, companies can offload the integration, deployment and management of the infrastructure to a third party, taking the pressure off their own IT staffs, and in private and hybrid cloud environments, they can keep their most business-critical data securely behind …

IDG Contributor Network: The contact center and CRM collision leads to a new dominant species

Some weeks ago I wrote that CRM and contact center are on a collision course. I argued that as the technologies used in CRM and the contact center will naturally mash up, the vendors of these traditionally distinct technologies will collide.In this post, I will expand upon that idea and talk about the future and a key aspect that will be important to successful synergies: how each domain leverages behaviors.CRM/contact center collision The first post argued that a co-mingling of the technologies used in CRM and the contact center worlds have occurred. This has been more of a lending of functionality. Seldom has true synergy emerged.To read this article in full or to leave a comment, please click here

On the ‘net: LinkedIn’s DC Design Principles


Operating a large-scale, rapidly growing network requires a philosophical change in how you plan, deploy, and operate your infrastructure. At LinkedIn, as we scaled our data center network, it became evident that we needed to provision and build networks not only as quickly as possible, but also with the most simple and minimalistic approaches possible — something that previously was not quite apparent to us. Adding a new component, a new feature, or a new service without any traffic loss or architectural change is challenging. —Network Computing
