Datanauts 170: NRE Labs – A First Step For Network Automation Training

The Datanauts explore NRE Labs, a free site where network engineers, or anyone, can get training on automation concepts and tools. NRE Labs is backed financially by Juniper Networks, but it's a free and open-source project that welcomes community involvement. Matt Oswalt is our guide for this tour of NRE Labs.

Remote code execution is possible by exploiting flaws in Vxworks

Eleven zero-day vulnerabilities in WindRiver’s VxWorks, a real-time operating system in use across an advertised 2 billion connected devices have been discovered by network security vendor Armis.Six of the vulnerabilities could enable remote attackers to access unpatched systems without any user interaction, even through a firewall according to Armis.

IoT roundup: Connected cows, food safety sensors and tracking rent-a-bikes

While the public image of agriculture remains a bit antiquated, the industry is actually an increasingly sophisticated one, and farmers have been particularly enthusiastic in their embrace of IoT. Everything from GPS-guided precision for planting, watering and harvesting to remote soil monitoring and in-depth yield analysis is available to the modern farmer.What’s more, the technology used in agriculture continues to evolve at speed; witness the recent partnership between Quantified Ag, a University of Nebraska-backed program that, among other things, can track livestock health via a system of IoT ear tags, and Cradlepoint, a vendor that makes the NetCloud Manager product.To read this article in full, please click here

Google Cloud to offer VMware data-center tools natively

Google this week said it would for the first time natively support VMware workloads in its Cloud service, giving customers more options for deploying enterprise applications.The hybrid cloud service called Google Cloud VMware Solution by CloudSimple will use VMware software-defined data center (SDCC) technologies including VMware vSphere, NSX and vSAN software deployed on a platform administered by CloudSimple for GCP.RELATED: How to make hybrid cloud work “Users will have full, native access to the full VMware stack including vCenter, vSAN and NSX-T. Google Cloud will provide the first line of support, working closely with CloudSimple to help ensure customers receive a streamlined product support experience and that their business-critical applications are supported with the SLAs that enterprise customers need,”  Thomas Kurian, CEO of Google Cloud wrote in a blog outlining the deal. To read this article in full, please click here

BrandPost: To SD-WAN or Not to SD-WAN? – The answer is in Your ROI

This is the part-one of a two-part blog series that will explore the return on investment that can be achieved by deploying a business-driven SD-WAN. In this installment, I will discuss how enterprise IT organizations can make the business case for moving from a traditional router-centric WAN architecture to a business-first networking model with SD-WAN.According to a survey conducted by Frost and Sullivan in 2018[1], 72 percent of respondents considered SD-WAN as a priority for their organization. Only a small percentage, six percent, indicated that they have no intention to deploy SD-WAN in the near term.To read this article in full, please click here

How to manage logs in Linux

Managing log files on Linux systems can be incredibly easy or painful. It all depends on what you mean by log management.If all you mean is how you can go about ensuring that your log files don’t eat up all the disk space on your Linux server, the issue is generally quite straightforward. Log files on Linux systems will automatically roll over, and the system will only maintain a fixed number of the rolled-over logs. Even so, glancing over what can easily be a group of 100 files can be overwhelming. In this post, we'll take a look at how the log rotation works and some of the most relevant log files. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ] Automatic log rotation Log files rotate frequently. What is the current log acquires a slightly different file name and a new log file is established. Take the syslog file as an example. This file is something of a catch-all for a lot of normal system messages. If you cd over to /var/log and take a look, you’ll probably see a series of syslog files like this:To read Continue reading

The cloud is the perennial metatrend of enterprise tech, yet it remains poorly understood. Peek under the hood and today’s real benefits emerge.

Coming soon: Eco-friendly data centers | TECH(feed)

As the push for sustainability across all businesses intensifies, so too will the push for greener IT infrastructure. Data centers are notorious for giving off thermal energy and being somewhat energy inefficient. Researchers at Rice University are looking for solutions to turn this heat into something a little more useful. In this episode of TECH(feed), Juliet discusses the push for green IT and how data centers could become much more energy efficient.

Big Data and Kubernetes – Why Your Spark & Hadoop Workloads Should Run Containerized…(1/4)

Starting this week, we will do a series of four blogposts on the intersection of Spark with Kubernetes. The first blog post will delve into the reasons why both platforms should be integrated. The second will deep-dive into Spark/K8s integration. The third will discuss usecases for Serverless and Big Data Analytics. The last post will round off with insights on best practices. 

Introduction

Most Cloud Native Architectures are designed in response to Digital Business initiatives – where it is important to personalize and to track minute customer interactions. The main components of a Cloud Native Platform inevitably leverage a microservices based design. At the same time, Big Data architectures based on Apache Spark have been implemented at 1000s of enterprises and support multiple data ingest capabilities whether real-time, streaming, interactive SQL platform while performing any kind of data processing (batch, analytical, in memory & graph, based) at the same time providing search, messaging & governance capabilities.

The RDBMS has been a fixture of the monolithic application architecture. Cloud Native applications, however, need to work with data formats of the loosely structured kind as well as the regularly structured data. This implies the need to support data streams that are Continue reading
