IoT Bringing Changes to Company Networks, Big Data Projects

The Internet of Things is big, and only getting bigger. A new report from Ovum suggestions now is the time IT needs to get networks ready to collect all this data, and use it to business advantage.

If 20 billion devices are projected to be connected to the Internet by 2020, the volume of data available will be on a scale never experienced before. That will open opportunities to exploit data and gain insights that IT and business managers haven’t had access to previously. Among other things, the Internet of Things is going to challenge current data capture, storage, and analysis practices. It will move data analysis out toward the edge of the network, closer to where the data is being generated. It is also likely to require new types of database technology.

VMware Fixes XSS Flaws in vRealize for Linux

VMware patched two cross-site scripting issues in several editions of its vRealize cloud software. These flaws could be exploited in stored XSS attacks and could result in the user’s workstation being compromised.

The input validation error exists in Linux versions of VMware vRealize Automation 6.x prior to 6.2.4 and vRealize Business Advanced and Enterprise 8.x prior to 8.2.5, VMware said in the advisory (VMSA-2016-0003). Linux users running affected versions should update to vRealize Automation 6.2.4 and vRealize Business Advanced and Enterprise 8.2.5 to address the problems.

Crate Built a Distributed SQL Database System To Run Within Containers

Crate-01Crate Technology has designed a database system for supporting Docker containers and microservices. The technology stresses ease of use, speed and scalability while retaining the ability to use SQL against very large data sets.

Crate was built to run in ephemeral environments, said Christian Lutz, Crate CEO. It was the ninth official Docker image in the Docker Registry and has been downloaded more than 350,000 times in the past six months. It can be managed with Docker tools, or with Kubernetes or Mesos.

“We believe that microservices architecture will definitely win,” Lutz said. “What you do with application containers already in production will very quickly create a requirement for databases [in containers] as well. If you don’t have the architecture for that, you can’t run in a scalable way in containers. You can take a database that doesn’t work in a container — obviously, SQL works in a container — but you have one node and one volume, but you can’t add hundreds of nodes. That’s why I think it will be very important when people start to put the database into containers.”

EFI Security Improvements And More For Linux 4.6

EFI-enabled systems will see some nice improvements with the upcoming Linux 4.6 kernel. 

One of the big EFI changes for Linux 4.6 that was already delayed twice before is using separate EFI page tables when executing EFI firmware code, which is done in order to isolate the EFI context from the rest of the kernel. This obviously is a big help from a security perspective.

AT&T Sheds More Light on SDN, NFV Initiative

The carrier is ahead of schedule in virtualizing its network, and unveils its ECOMP software platform for building a software-centric infrastructure.

AT&T’s high-profile effort to transform its infrastructure into a software-defined environment is humming along.At the Open Networking Summit (ONS) 2016 this week, John Donovan, chief strategy officer and group president of AT&T technology and operations, gave attendees an update on where the carrier stands with its multi-year Domain 2.0 project to embrace such technologies as software-defined networking (SDN) and network-functions virtualization (NFV) within its data centers.

In an accompanying post on the company blog March 15, Donovan wrote that AT&T is ahead of schedule in virtualizing its network, and that trials of the carrier’s CORD project—which is being used to help fuel AT&T’s fiber-optic network project—will kick off in the next few weeks.

Closed Silo Challenges to an Open Web

BIZ integralintegrationThe growing trend of closed content silos—publishing platforms that require a login in order to view the content—is a step away from a more open web. As this trend continues, owners of closed silos will have even more control over published content and traffic that content drives. 

This is why content producers should also consider ways to publish content openly, and for their users to have the option to access content through their web browsers rather than being driven into closed ecosystems.
